Known Indirect Subclasses

AutoCompleteTextView, CheckBox, CompoundButton, ExtractEditText, MultiAutoCompleteTextView, RadioButton, Switch, ToggleButton

AutoCompleteTextView	An editable text view that shows completion suggestions automatically while the user is typing.
CheckBox	A checkbox is a specific type of two-states button that can be either checked or unchecked.
CompoundButton	A button with two states, checked and unchecked.
ExtractEditText	* Specialization of `EditText` for showing and interacting with the extracted text in a full-screen input method.
MultiAutoCompleteTextView	An editable text view, extending `AutoCompleteTextView`, that can show completion suggestions for the substring of the text where the user is typing instead of necessarily for the entire thing.
RadioButton	A radio button is a two-states button that can be either checked or unchecked.
Switch	A Switch is a two-state toggle switch widget that can select between two options.
ToggleButton	Displays checked/unchecked states as a button with a "light" indicator and by default accompanied with the text "ON" or "OFF".

A user interface element that displays text to the user. To provide user-editable text, see EditText.

The following code sample shows a typical use, with an XML layout and code to modify the contents of the text view:

<LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent">
     <TextView
         android:id="@+id/text_view_id"
         android:layout_height="wrap_content"
         android:layout_width="wrap_content"
         android:text="@string/hello" />
  </LinearLayout>

This code sample demonstrates how to modify the contents of the text view defined in the previous XML layout:

public class MainActivity extends Activity {
 
     protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          final TextView helloTextView = (TextView) findViewById(R.id.text_view_id);
          helloTextView.setText(R.string.user_greeting);
      }
  }

Inherited XML attributes

From class View

android:accessibilityHeading

Whether or not this view is a heading for accessibility purposes.

May be a boolean value, such as "true" or "false".

android:alpha

alpha property of the view, as a value between 0 (completely transparent) and 1 (completely opaque).

May be a floating point value, such as "1.2".

android:background

A drawable to use as the background. This can be either a reference to a full drawable resource (such as a PNG image, 9-patch, XML state list description, etc), or a solid color such as "#ff000000" (black).

May be a reference to another resource, in the form "@[+][package:]type/name" or a theme attribute in the form "?[package:]type/name".

May be a color value, in the form of "rgb", "argb", "rrggbb", or "aarrggbb".

android:clickable

Defines whether this view reacts to click events.

May be a boolean value, such as "true" or "false".

android:contentDescription

Defines text that briefly describes content of the view. This property is used primarily for accessibility. Since some views do not have textual representation this attribute can be used for providing such.

May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;

android:drawingCacheQuality

Defines the quality of translucent drawing caches. This property is used only when the drawing cache is enabled and translucent. The default value is auto. Deprecated: The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11.

Must be one of the following constant values.

Constant	Value	Description
auto	0	Lets the framework decide what quality level should be used for the drawing cache. Deprecated: The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11.
high	2	High quality. When set to high quality, the drawing cache uses a higher color depth but uses more memory. Deprecated: The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11.
low	1	Low quality. When set to low quality, the drawing cache uses a lower color depth, thus losing precision in rendering gradients, but uses less memory. Deprecated: The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11.

android:duplicateParentState

When this attribute is set to true, the view gets its drawable state (focused, pressed, etc.) from its direct parent rather than from itself.

May be a boolean value, such as "true" or "false".

android:fadeScrollbars

Defines whether to fade out scrollbars when they are not in use.

May be a boolean value, such as "true" or "false".

android:fadingEdgeLength

Defines the length of the fading edges.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

android:filterTouchesWhenObscured

Specifies whether to filter touches when the view's window is obscured by another visible window. When set to true, the view will not receive touches whenever a toast, dialog or other window appears above the view's window. Refer to the android.view.View security documentation for more details.

May be a boolean value, such as "true" or "false".

android:fitsSystemWindows

Boolean internal attribute to adjust view layout based on system windows such as the status bar. If true, adjusts the padding of this view to leave space for the system windows. Will only take effect if this view is in a non-embedded activity.

May be a boolean value, such as "true" or "false".

android:focusable

Controls whether a view can take focus. By default, this is "auto" which lets the framework determine whether a user can move focus to a view. By setting this attribute to true the view is allowed to take focus. By setting it to "false" the view will not take focus. This value does not impact the behavior of directly calling android.view.View#requestFocus, which will always request focus regardless of this view. It only impacts where focus navigation will try to move focus.

May be a boolean value, such as "true" or "false".

Must be one of the following constant values.

Constant	Value	Description
auto	10

android:focusableInTouchMode

Boolean that controls whether a view can take focus while in touch mode. If this is true for a view, that view can gain focus when clicked on, and can keep focus if another view is clicked on that doesn't have this attribute set to true.

May be a boolean value, such as "true" or "false".

android:focusedByDefault

May be a boolean value, such as "true" or "false".

android:hapticFeedbackEnabled

Boolean that controls whether a view should have haptic feedback enabled for events such as long presses.

May be a boolean value, such as "true" or "false".

android:id

Supply an identifier name for this view, to later retrieve it with View.findViewById() or Activity.findViewById(). This must be a resource reference; typically you set this using the @+ syntax to create a new ID resources. For example: android:id="@+id/my_id" which allows you to later retrieve the view with findViewById(R.id.my_id).

May be a reference to another resource, in the form "@[+][package:]type/name" or a theme attribute in the form "?[package:]type/name".

android:isScrollContainer

Set this if the view will serve as a scrolling container, meaning that it can be resized to shrink its overall window so that there will be space for an input method. If not set, the default value will be true if "scrollbars" has the vertical scrollbar set, else it will be false.

May be a boolean value, such as "true" or "false".

android:keepScreenOn

Controls whether the view's window should keep the screen on while visible.

May be a boolean value, such as "true" or "false".

"ltr" is the direction used in "en-US". The default for this attribute is "inherit".

Must be one of the following constant values.

Constant	Value	Description
inherit	2	Inherit from parent.
locale	3	Locale.
ltr	0	Left-to-Right.
rtl	1	Right-to-Left.

android:longClickable

Defines whether this view reacts to long click events.

This value will take precedence over any of the edge-specific values (paddingLeft, paddingTop, paddingRight, paddingBottom, paddingHorizontal and paddingVertical), but will not override paddingStart or paddingEnd, if set. A view's size will include its padding. If a android.R.attr#background is provided, the padding will initially be set to that (0 if the drawable does not have padding). Explicitly setting a padding value will override the corresponding padding found in the background.

Inherited constants

From class View

`Int`	`ACCESSIBILITY_LIVE_REGION_ASSERTIVE` Live region mode specifying that accessibility services should interrupt ongoing speech to immediately announce changes to this view. Use with `setAccessibilityLiveRegion(int)`.
`Int`	`ACCESSIBILITY_LIVE_REGION_NONE` Live region mode specifying that accessibility services should not automatically announce changes to this view. This is the default live region mode for most views. Use with `setAccessibilityLiveRegion(int)`.
`Int`	`ACCESSIBILITY_LIVE_REGION_POLITE` Live region mode specifying that accessibility services should announce changes to this view. Use with `setAccessibilityLiveRegion(int)`.
`Int`	`AUTOFILL_FLAG_INCLUDE_NOT_IMPORTANT_VIEWS` Flag requesting you to add views that are marked as not important for autofill (see `setImportantForAutofill(int)`) to a `ViewStructure`.
`String`	`AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DATE` Hint indicating that this view can be autofilled with a credit card expiration date. It should be used when the credit card expiration date is represented by just one view; if it is represented by more than one (for example, one view for the month and another view for the year), then each of these views should use the hint specific for the unit (`AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DAY`, `AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_MONTH`, or `AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_YEAR`). Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DATE}`). When annotating a view with this hint, it's recommended to use a date autofill value to avoid ambiguity when the autofill service provides a value for it. To understand why a value can be ambiguous, consider "April of 2020", which could be represented as either of the following options: `"04/2020"` `"4/2020"` `"2020/04"` `"2020/4"` `"April/2020"` `"Apr/2020"` You define a date autofill value for the view by overriding the following methods: `getAutofillType()` to return `AUTOFILL_TYPE_DATE`. `getAutofillValue()` to return a `AutofillValue#forDate(long)`. `autofill(android.view.autofill.AutofillValue)` to expect a data autofillvalue. See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DAY` Hint indicating that this view can be autofilled with a credit card expiration day. Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DAY}`). See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_MONTH` Hint indicating that this view can be autofilled with a credit card expiration month. Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_MONTH}`). When annotating a view with this hint, it's recommended to use a text autofill value whose value is the numerical representation of the month, starting on `1` to avoid ambiguity when the autofill service provides a value for it. To understand why a value can be ambiguous, consider "January", which could be represented as either of `"1"`: recommended way. `"0"`: if following the `Calendar#MONTH` convention. `"January"`: full name, in English. `"jan"`: abbreviated name, in English. `"Janeiro"`: full name, in another language. Another recommended approach is to use a date autofill value - see `AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DATE` for more details. See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_YEAR` Hint indicating that this view can be autofilled with a credit card expiration year. Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_YEAR}`). See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_CREDIT_CARD_NUMBER` Hint indicating that this view can be autofilled with a credit card number.

See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_EMAIL_ADDRESS` Hint indicating that this view can be autofilled with an email address. Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_EMAIL_ADDRESS}`). See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_NAME` Hint indicating that this view can be autofilled with a user's real name. Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_NAME}`).

`String`	`AUTOFILL_HINT_POSTAL_ADDRESS` Hint indicating that this view can be autofilled with a postal address. Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_POSTAL_ADDRESS}`). See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_POSTAL_CODE` Hint indicating that this view can be autofilled with a postal code. Can be used with either `setAutofillHints(java.lang.String[])` or `android:autofillHint` (in which case the value should be `{@value #AUTOFILL_HINT_POSTAL_CODE}`). See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`String`	`AUTOFILL_HINT_USERNAME` Hint indicating that this view can be autofilled with a username.

See `setAutofillHints(java.lang.String...)` for more info about autofill hints.
`Int`	`AUTOFILL_TYPE_DATE` Autofill type for a field that contains a date, which is represented by a long representing the number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT (see `java.util.Date#getTime()`. `AutofillValue` instances for autofilling a `View` can be obtained through `AutofillValue#forDate(long)`, and the values passed to autofill a `View` can be fetched through `AutofillValue#getDateValue()`.
`Int`	`AUTOFILL_TYPE_LIST` Autofill type for a selection list field, which is filled by an `int` representing the element index inside the list (starting at `0`). `AutofillValue` instances for autofilling a `View` can be obtained through `AutofillValue#forList(int)`, and the value passed to autofill a `View` can be fetched through `AutofillValue#getListValue()`. The available options in the selection list are typically provided by `android.app.assist.AssistStructure.ViewNode#getAutofillOptions()`.
`Int`	`AUTOFILL_TYPE_NONE` Autofill type for views that cannot be autofilled. Typically used when the view is read-only; for example, a text label.
`Int`	`AUTOFILL_TYPE_TEXT` Autofill type for a text field, which is filled by a `CharSequence`. `AutofillValue` instances for autofilling a `View` can be obtained through `AutofillValue#forText(CharSequence)`, and the value passed to autofill a `View` can be fetched through `AutofillValue#getTextValue()`.
`Int`	`AUTOFILL_TYPE_TOGGLE` Autofill type for a togglable field, which is filled by a `boolean`. `AutofillValue` instances for autofilling a `View` can be obtained through `AutofillValue#forToggle(boolean)`, and the value passed to autofill a `View` can be fetched through `AutofillValue#getToggleValue()`.
`Int`	`DRAG_FLAG_GLOBAL` Flag indicating that a drag can cross window boundaries. When `startDragAndDrop(android.content.ClipData,android.view.View.DragShadowBuilder,java.lang.Object,int)` is called with this flag set, all visible applications with targetSdkVersion >= `API 24` will be able to participate in the drag operation and receive the dragged content. If this is the only flag set, then the drag recipient will only have access to text data and intents contained in the `ClipData` object. Access to URIs contained in the `ClipData` is determined by other DRAG_FLAG_GLOBAL_* flags
`Int`	`DRAG_FLAG_GLOBAL_PERSISTABLE_URI_PERMISSION` When this flag is used with `DRAG_FLAG_GLOBAL_URI_READ` and/or , the URI permission grant can be persisted across device reboots until explicitly revoked with `android.content.Context#revokeUriPermission(Uri, int)` Context.revokeUriPermission}.
`Int`	`DRAG_FLAG_GLOBAL_PREFIX_URI_PERMISSION` When this flag is used with `DRAG_FLAG_GLOBAL_URI_READ` and/or , the URI permission grant applies to any URI that is a prefix match against the original granted URI.
`Int`	`DRAG_FLAG_GLOBAL_URI_READ` When this flag is used with `DRAG_FLAG_GLOBAL`, the drag recipient will be able to request read access to the content URI(s) contained in the `ClipData` object.
`Int`	`DRAG_FLAG_GLOBAL_URI_WRITE` When this flag is used with `DRAG_FLAG_GLOBAL`, the drag recipient will be able to request write access to the content URI(s) contained in the `ClipData` object.
`Int`	`DRAG_FLAG_OPAQUE` Flag indicating that the drag shadow will be opaque. When `startDragAndDrop(android.content.ClipData,android.view.View.DragShadowBuilder,java.lang.Object,int)` is called with this flag set, the drag shadow will be opaque, otherwise, it will be semitransparent.
`Int`	`DRAWING_CACHE_QUALITY_AUTO` Enables automatic quality mode for the drawing cache.
`Int`	`DRAWING_CACHE_QUALITY_HIGH` Enables high quality mode for the drawing cache.
`Int`	`DRAWING_CACHE_QUALITY_LOW` Enables low quality mode for the drawing cache.
`Int`	`FIND_VIEWS_WITH_CONTENT_DESCRIPTION` Find find views that contain the specified content description.
`Int`	`FIND_VIEWS_WITH_TEXT` Find views that render the specified text.
`Int`	`FOCUSABLE` This view wants keystrokes. Use with `setFocusable(int)` and `android:focusable`.
`Int`	`FOCUSABLES_ALL` View flag indicating whether `addFocusables(java.util.ArrayList,int,int)` should add all focusable Views regardless if they are focusable in touch mode.
`Int`	`FOCUSABLES_TOUCH_MODE` View flag indicating whether `addFocusables(java.util.ArrayList,int,int)` should add only Views focusable in touch mode.
`Int`	`FOCUSABLE_AUTO` This view determines focusability automatically. This is the default. Use with `setFocusable(int)` and `android:focusable`.
`Int`	`FOCUS_BACKWARD` Use with `focusSearch(int)`. Move focus to the previous selectable item.
`Int`	`FOCUS_DOWN` Use with `focusSearch(int)`. Move focus down.
`Int`	`FOCUS_FORWARD` Use with `focusSearch(int)`. Move focus to the next selectable item.
`Int`	`FOCUS_LEFT` Use with `focusSearch(int)`. Move focus to the left.
`Int`	`FOCUS_RIGHT` Use with `focusSearch(int)`. Move focus to the right.
`Int`	`FOCUS_UP` Use with `focusSearch(int)`. Move focus up.
`Int`	`GONE` This view is invisible, and it doesn't take any space for layout purposes. Use with `setVisibility` and `android:visibility`.
`Int`	`HAPTIC_FEEDBACK_ENABLED` View flag indicating whether this view should have haptic feedback enabled for events such as long presses.
`Int`	`IMPORTANT_FOR_ACCESSIBILITY_AUTO` Automatically determine whether a view is important for accessibility.
`Int`	`IMPORTANT_FOR_ACCESSIBILITY_NO` The view is not important for accessibility.
`Int`	`IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS` The view is not important for accessibility, nor are any of its descendant views.
`Int`	`IMPORTANT_FOR_ACCESSIBILITY_YES` The view is important for accessibility.
`Int`	`IMPORTANT_FOR_AUTOFILL_AUTO` Automatically determine whether a view is important for autofill.
`Int`	`IMPORTANT_FOR_AUTOFILL_NO` The view is not important for autofill, but its children (if any) will be traversed.
`Int`	`IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS` The view is not important for autofill, and its children (if any) will not be traversed.
`Int`	`IMPORTANT_FOR_AUTOFILL_YES` The view is important for autofill, and its children (if any) will be traversed.
`Int`	`IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS` The view is important for autofill, but its children (if any) will not be traversed.
`Int`	`INVISIBLE` This view is invisible, but it still takes up space for layout purposes. Use with `setVisibility` and `android:visibility`.
`Int`	`KEEP_SCREEN_ON` View flag indicating that the screen should remain on while the window containing this view is visible to the user. This effectively takes care of automatically setting the WindowManager's `WindowManager.LayoutParams#FLAG_KEEP_SCREEN_ON`.
`Int`	`LAYER_TYPE_HARDWARE` Indicates that the view has a hardware layer. A hardware layer is backed by a hardware specific texture (generally Frame Buffer Objects or FBO on OpenGL hardware) and causes the view to be rendered using Android's hardware rendering pipeline, but only if hardware acceleration is turned on for the view hierarchy. When hardware acceleration is turned off, hardware layers behave exactly as `software layers`. A hardware layer is useful to apply a specific color filter and/or blending mode and/or translucency to a view and all its children. A hardware layer can be used to cache a complex view tree into a texture and reduce the complexity of drawing operations. For instance, when animating a complex view tree with a translation, a hardware layer can be used to render the view tree only once. A hardware layer can also be used to increase the rendering quality when rotation transformations are applied on a view. It can also be used to prevent potential clipping issues when applying 3D transforms on a view.
`Int`	`LAYER_TYPE_NONE` Indicates that the view does not have a layer.
`Int`	`LAYER_TYPE_SOFTWARE` Indicates that the view has a software layer. A software layer is backed by a bitmap and causes the view to be rendered using Android's software rendering pipeline, even if hardware acceleration is enabled. Software layers have various usages: When the application is not using hardware acceleration, a software layer is useful to apply a specific color filter and/or blending mode and/or translucency to a view and all its children. When the application is using hardware acceleration, a software layer is useful to render drawing primitives not supported by the hardware accelerated pipeline. It can also be used to cache a complex view tree into a texture and reduce the complexity of drawing operations. For instance, when animating a complex view tree with a translation, a software layer can be used to render the view tree only once. Software layers should be avoided when the affected view tree updates often. Every update will require to re-render the software layer, which can potentially be slow (particularly when hardware acceleration is turned on since the layer will have to be uploaded into a hardware texture after every update.)
`Int`	`LAYOUT_DIRECTION_INHERIT` Horizontal layout direction of this view is inherited from its parent. Use with `setLayoutDirection`.
`Int`	`LAYOUT_DIRECTION_LOCALE` Horizontal layout direction of this view is from deduced from the default language script for the locale. Use with `setLayoutDirection`.
`Int`	`LAYOUT_DIRECTION_LTR` Horizontal layout direction of this view is from Left to Right. Use with `setLayoutDirection`.
`Int`	`LAYOUT_DIRECTION_RTL` Horizontal layout direction of this view is from Right to Left. Use with `setLayoutDirection`.
`Int`	`MEASURED_HEIGHT_STATE_SHIFT` Bit shift of `MEASURED_STATE_MASK` to get to the height bits for functions that combine both width and height into a single int, such as `getMeasuredState()` and the childState argument of `resolveSizeAndState(int,int,int)`.
`Int`	`MEASURED_SIZE_MASK` Bits of `getMeasuredWidthAndState()` and `getMeasuredWidthAndState()` that provide the actual measured size.
`Int`	`MEASURED_STATE_MASK` Bits of `getMeasuredWidthAndState()` and `getMeasuredWidthAndState()` that provide the additional state bits.
`Int`	`MEASURED_STATE_TOO_SMALL` Bit of `getMeasuredWidthAndState()` and `getMeasuredWidthAndState()` that indicates the measured size is smaller that the space the view would like to have.
`Int`	`NOT_FOCUSABLE` This view does not want keystrokes. Use with `setFocusable(int)` and `android:focusable`.
`Int`	`NO_ID` Used to mark a View that has no ID.
`Int`	`OVER_SCROLL_ALWAYS` Always allow a user to over-scroll this view, provided it is a view that can scroll.
`Int`	`OVER_SCROLL_IF_CONTENT_SCROLLS` Allow a user to over-scroll this view only if the content is large enough to meaningfully scroll, provided it is a view that can scroll.
`Int`	`OVER_SCROLL_NEVER` Never allow a user to over-scroll this view.
`Int`	`SCREEN_STATE_OFF` Indicates that the screen has changed state and is now off.
`Int`	`SCREEN_STATE_ON` Indicates that the screen has changed state and is now on.
`Int`	`SCROLLBARS_INSIDE_INSET` The scrollbar style to display the scrollbars inside the padded area, increasing the padding of the view. The scrollbars will not overlap the content area of the view.
`Int`	`SCROLLBARS_INSIDE_OVERLAY` The scrollbar style to display the scrollbars inside the content area, without increasing the padding. The scrollbars will be overlaid with translucency on the view's content.
`Int`	`SCROLLBARS_OUTSIDE_INSET` The scrollbar style to display the scrollbars at the edge of the view, increasing the padding of the view. The scrollbars will only overlap the background, if any.
`Int`	`SCROLLBARS_OUTSIDE_OVERLAY` The scrollbar style to display the scrollbars at the edge of the view, without increasing the padding. The scrollbars will be overlaid with translucency.
`Int`	`SCROLLBAR_POSITION_DEFAULT` Position the scroll bar at the default position as determined by the system.
`Int`	`SCROLLBAR_POSITION_LEFT` Position the scroll bar along the left edge.
`Int`	`SCROLLBAR_POSITION_RIGHT` Position the scroll bar along the right edge.
`Int`	`SCROLL_AXIS_HORIZONTAL` Indicates scrolling along the horizontal axis.
`Int`	`SCROLL_AXIS_NONE` Indicates no axis of view scrolling.
`Int`	`SCROLL_AXIS_VERTICAL` Indicates scrolling along the vertical axis.
`Int`	`SCROLL_INDICATOR_BOTTOM` Scroll indicator direction for the bottom edge of the view.
`Int`	`SCROLL_INDICATOR_END` Scroll indicator direction for the ending edge of the view. Resolved according to the view's layout direction, see `getLayoutDirection()` for more information.
`Int`	`SCROLL_INDICATOR_LEFT` Scroll indicator direction for the left edge of the view.
`Int`	`SCROLL_INDICATOR_RIGHT` Scroll indicator direction for the right edge of the view.
`Int`	`SCROLL_INDICATOR_START` Scroll indicator direction for the starting edge of the view. Resolved according to the view's layout direction, see `getLayoutDirection()` for more information.
`Int`	`SCROLL_INDICATOR_TOP` Scroll indicator direction for the top edge of the view.
`Int`	`SOUND_EFFECTS_ENABLED` View flag indicating whether this view should have sound effects enabled for events such as clicking and touching.
`Int`	`STATUS_BAR_HIDDEN`
`Int`	`STATUS_BAR_VISIBLE`
`Int`	`SYSTEM_UI_FLAG_FULLSCREEN` Flag for `setSystemUiVisibility(int)`: View has requested to go into the normal fullscreen mode so that its content can take over the screen while still allowing the user to interact with the application. This has the same visual effect as `WindowManager.LayoutParams.FLAG_FULLSCREEN`, meaning that non-critical screen decorations (such as the status bar) will be hidden while the user is in the View's window, focusing the experience on that content. Unlike the window flag, if you are using ActionBar in overlay mode with `Window#FEATURE_ACTION_BAR_OVERLAY`, then enabling this flag will also hide the action bar. This approach to going fullscreen is best used over the window flag when it is a transient state -- that is, the application does this at certain points in its user interaction where it wants to allow the user to focus on content, but not as a continuous state. For situations where the application would like to simply stay full screen the entire time (such as a game that wants to take over the screen), the `window flag` is usually a better approach. The state set here will be removed by the system in various situations (such as the user moving to another application) like the other system UI states. When using this flag, the application should provide some easy facility for the user to go out of it. A common example would be in an e-book reader, where tapping on the screen brings back whatever screen and UI decorations that had been hidden while the user was immersed in reading the book.
`Int`	`SYSTEM_UI_FLAG_HIDE_NAVIGATION` Flag for `setSystemUiVisibility(int)`: View has requested that the system navigation be temporarily hidden. This is an even less obtrusive state than that called for by `SYSTEM_UI_FLAG_LOW_PROFILE`; on devices that draw essential navigation controls (Home, Back, and the like) on screen, `SYSTEM_UI_FLAG_HIDE_NAVIGATION` will cause those to disappear. This is useful (in conjunction with the `FLAG_FULLSCREEN` and `FLAG_LAYOUT_IN_SCREEN` window flags) for displaying content using every last pixel on the display. There is a limitation: because navigation controls are so important, the least user interaction will cause them to reappear immediately. When this happens, both this flag and `SYSTEM_UI_FLAG_FULLSCREEN` will be cleared automatically, so that both elements reappear at the same time.
`Int`	`SYSTEM_UI_FLAG_IMMERSIVE` Flag for `setSystemUiVisibility(int)`: View would like to remain interactive when hiding the navigation bar with `SYSTEM_UI_FLAG_HIDE_NAVIGATION`. If this flag is not set, `SYSTEM_UI_FLAG_HIDE_NAVIGATION` will be force cleared by the system on any user interaction. Since this flag is a modifier for `SYSTEM_UI_FLAG_HIDE_NAVIGATION`, it only has an effect when used in combination with that flag.
`Int`	`SYSTEM_UI_FLAG_IMMERSIVE_STICKY` Flag for `setSystemUiVisibility(int)`: View would like to remain interactive when hiding the status bar with `SYSTEM_UI_FLAG_FULLSCREEN` and/or hiding the navigation bar with `SYSTEM_UI_FLAG_HIDE_NAVIGATION`. Use this flag to create an immersive experience while also hiding the system bars. If this flag is not set, `SYSTEM_UI_FLAG_HIDE_NAVIGATION` will be force cleared by the system on any user interaction, and `SYSTEM_UI_FLAG_FULLSCREEN` will be force-cleared by the system if the user swipes from the top of the screen. When system bars are hidden in immersive mode, they can be revealed temporarily with system gestures, such as swiping from the top of the screen. These transient system bars will overlay app's content, may have some degree of transparency, and will automatically hide after a short timeout. Since this flag is a modifier for `SYSTEM_UI_FLAG_FULLSCREEN` and `SYSTEM_UI_FLAG_HIDE_NAVIGATION`, it only has an effect when used in combination with one or both of those flags.
`Int`	`SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN` Flag for `setSystemUiVisibility(int)`: View would like its window to be laid out as if it has requested `SYSTEM_UI_FLAG_FULLSCREEN`, even if it currently hasn't. This allows it to avoid artifacts when switching in and out of that mode, at the expense that some of its user interface may be covered by screen decorations when they are shown. You can perform layout of your inner UI elements to account for non-fullscreen system UI through the `fitSystemWindows(android.graphics.Rect)` method. Note: on displays that have a `DisplayCutout`, the window may still be placed differently than if `SYSTEM_UI_FLAG_FULLSCREEN` was set, if the window's `WindowManager.LayoutParams#layoutInDisplayCutoutMode` is `WindowManager.LayoutParams#LAYOUT_IN_DISPLAY_CUTOUT_MODE_DEFAULT`. To avoid this, use either of the other modes.
`Int`	`SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION` Flag for `setSystemUiVisibility(int)`: View would like its window to be laid out as if it has requested `SYSTEM_UI_FLAG_HIDE_NAVIGATION`, even if it currently hasn't. This allows it to avoid artifacts when switching in and out of that mode, at the expense that some of its user interface may be covered by screen decorations when they are shown. You can perform layout of your inner UI elements to account for the navigation system UI through the `fitSystemWindows(android.graphics.Rect)` method.
`Int`	`SYSTEM_UI_FLAG_LAYOUT_STABLE` Flag for `setSystemUiVisibility(int)`: When using other layout flags, we would like a stable view of the content insets given to `fitSystemWindows(android.graphics.Rect)`. This means that the insets seen there will always represent the worst case that the application can expect as a continuous state. In the stock Android UI this is the space for the system bar, nav bar, and status bar, but not more transient elements such as an input method. The stable layout your UI sees is based on the system UI modes you can switch to. That is, if you specify `SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN` then you will get a stable layout for changes of the `SYSTEM_UI_FLAG_FULLSCREEN` mode; if you specify `SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN` and `SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION`, then you can transition to `SYSTEM_UI_FLAG_FULLSCREEN` and `SYSTEM_UI_FLAG_HIDE_NAVIGATION` with a stable layout. (Note that you should avoid using `SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION` by itself.) If you have set the window flag `WindowManager.LayoutParams#FLAG_FULLSCREEN` to hide the status bar (instead of using `SYSTEM_UI_FLAG_FULLSCREEN`), then a hidden status bar will be considered a "stable" state for purposes here. This allows your UI to continually hide the status bar, while still using the system UI flags to hide the action bar while still retaining a stable layout. Note that changing the window fullscreen flag will never provide a stable layout for a clean transition. If you are using ActionBar in overlay mode with `Window#FEATURE_ACTION_BAR_OVERLAY`, this flag will also impact the insets it adds to those given to the application.
`Int`	`SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR` Flag for `setSystemUiVisibility(int)`: Requests the navigation bar to draw in a mode that is compatible with light navigation bar backgrounds. For this to take effect, the window must request `FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS` but not `FLAG_TRANSLUCENT_NAVIGATION`.
`Int`	`SYSTEM_UI_FLAG_LIGHT_STATUS_BAR` Flag for `setSystemUiVisibility(int)`: Requests the status bar to draw in a mode that is compatible with light status bar backgrounds. For this to take effect, the window must request `FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS` but not `FLAG_TRANSLUCENT_STATUS`.
`Int`	`SYSTEM_UI_FLAG_LOW_PROFILE` Flag for `setSystemUiVisibility(int)`: View has requested the system UI to enter an unobtrusive "low profile" mode. This is for use in games, book readers, video players, or any other "immersive" application where the usual system chrome is deemed too distracting. In low profile mode, the status bar and/or navigation icons may dim.
`Int`	`SYSTEM_UI_FLAG_VISIBLE` Special constant for `setSystemUiVisibility(int)`: View has requested the system UI (status bar) to be visible (the default).
`Int`	`SYSTEM_UI_LAYOUT_FLAGS` Flags that can impact the layout in relation to system UI.
`Int`	`TEXT_ALIGNMENT_CENTER` Center the paragraph, e.g. ALIGN_CENTER. Use with `setTextAlignment(int)`
`Int`	`TEXT_ALIGNMENT_GRAVITY` Default for the root view. The gravity determines the text alignment, ALIGN_NORMAL, ALIGN_CENTER, or ALIGN_OPPOSITE, which are relative to each paragraph's text direction. Use with `setTextAlignment(int)`
`Int`	`TEXT_ALIGNMENT_INHERIT` Default text alignment. The text alignment of this View is inherited from its parent. Use with `setTextAlignment(int)`
`Int`	`TEXT_ALIGNMENT_TEXT_END` Align to the end of the paragraph, e.g. ALIGN_OPPOSITE. Use with `setTextAlignment(int)`
`Int`	`TEXT_ALIGNMENT_TEXT_START` Align to the start of the paragraph, e.g. ALIGN_NORMAL. Use with `setTextAlignment(int)`
`Int`	`TEXT_ALIGNMENT_VIEW_END` Align to the end of the view, which is ALIGN_RIGHT if the view's resolved layoutDirection is LTR, and ALIGN_LEFT otherwise. Use with `setTextAlignment(int)`
`Int`	`TEXT_ALIGNMENT_VIEW_START` Align to the start of the view, which is ALIGN_LEFT if the view's resolved layoutDirection is LTR, and ALIGN_RIGHT otherwise. Use with `setTextAlignment(int)`

Inherited functions

From class View

`Unit`	`addChildrenForAccessibility(outChildren: ArrayList<View!>!)` Adds the children of this View relevant for accessibility to the given list as output. Since some Views are not important for accessibility the added child views are not necessarily direct children of this view, rather they are the first level of descendants important for accessibility.
`Unit`	`addFocusables(views: ArrayList<View!>!, direction: Int)` Add any focusable views that are descendants of this view (possibly including this view if it is focusable itself) to views. If we are in touch mode, only add views that are also focusable in touch mode.
`Unit`	`addFocusables(views: ArrayList<View!>!, direction: Int, focusableMode: Int)` Adds any focusable views that are descendants of this view (possibly including this view if it is focusable itself) to views. This method adds all focusable views regardless if we are in touch mode or only views focusable in touch mode if we are in touch mode or only views that can take accessibility focus if accessibility is enabled depending on the focusable mode parameter.
`Unit`	`addKeyboardNavigationClusters(views: MutableCollection<View!>, direction: Int)` Adds any keyboard navigation cluster roots that are descendants of this view (possibly including this view if it is a cluster root itself) to views.
`Unit`	`addOnAttachStateChangeListener(listener: View.OnAttachStateChangeListener!)` Add a listener for attach state changes. This listener will be called whenever this view is attached or detached from a window. Remove the listener using `removeOnAttachStateChangeListener(android.view.View.OnAttachStateChangeListener)`.
`Unit`	`addOnLayoutChangeListener(listener: View.OnLayoutChangeListener!)` Add a listener that will be called when the bounds of the view change due to layout processing.
`Unit`	`addOnUnhandledKeyEventListener(listener: View.OnUnhandledKeyEventListener!)` Adds a listener which will receive unhandled `KeyEvent`s. This must be called on the UI thread.
`Unit`	`addTouchables(views: ArrayList<View!>!)` Add any touchable views that are descendants of this view (possibly including this view if it is touchable itself) to views.
`ViewPropertyAnimator!`	`animate()` This method returns a ViewPropertyAnimator object, which can be used to animate specific properties on this View.
`Unit`	`announceForAccessibility(text: CharSequence!)` Convenience method for sending a `AccessibilityEvent#TYPE_ANNOUNCEMENT` `AccessibilityEvent` to suggest that an accessibility service announce the specified text to its users. Note: The event generated with this API carries no semantic meaning, and is appropriate only in exceptional situations. Apps can generally achieve correct behavior for accessibility by accurately supplying the semantics of their UI. They should not need to specify what exactly is announced to users.
`Unit`	`autofill(values: SparseArray<AutofillValue!>)` Automatically fills the content of the virtual children within this view. Views with virtual children support the Autofill Framework mainly by: Providing the metadata defining what the virtual children mean and how they can be autofilled. Implementing the methods that autofill the virtual children. `onProvideAutofillVirtualStructure(android.view.ViewStructure,int)` is responsible for the former, this method is responsible for the latter - see `autofill(android.view.autofill.AutofillValue)` and `onProvideAutofillVirtualStructure(android.view.ViewStructure,int)` for more info about autofill. If a child value is updated asynchronously, the next call to `AutofillManager#notifyValueChanged(View, int, AutofillValue)` must happen after the value was changed to the autofilled value. If not, the child will not be considered autofilled. Note: To indicate that a virtual view was autofilled, `?android:attr/autofilledHighlight` should be drawn over it until the data changes.
`Boolean`	`awakenScrollBars()` Trigger the scrollbars to draw. When invoked this method starts an animation to fade the scrollbars out after a default delay. If a subclass provides animated scrolling, the start delay should equal the duration of the scrolling animation. The animation starts only if at least one of the scrollbars is enabled, as specified by `isHorizontalScrollBarEnabled()` and `isVerticalScrollBarEnabled()`. When the animation is started, this method returns true, and false otherwise. If the animation is started, this method calls `invalidate()`; in that case the caller should not call `invalidate()`. This method should be invoked every time a subclass directly updates the scroll parameters. This method is automatically invoked by `scrollBy(int,int)` and `scrollTo(int,int)`.
`Boolean`	`awakenScrollBars(startDelay: Int)` Trigger the scrollbars to draw. When invoked this method starts an animation to fade the scrollbars out after a fixed delay. If a subclass provides animated scrolling, the start delay should equal the duration of the scrolling animation. The animation starts only if at least one of the scrollbars is enabled, as specified by `isHorizontalScrollBarEnabled()` and `isVerticalScrollBarEnabled()`. When the animation is started, this method returns true, and false otherwise. If the animation is started, this method calls `invalidate()`; in that case the caller should not call `invalidate()`. This method should be invoked every time a subclass directly updates the scroll parameters.
`Boolean`	`awakenScrollBars(startDelay: Int, invalidate: Boolean)` Trigger the scrollbars to draw. When invoked this method starts an animation to fade the scrollbars out after a fixed delay. If a subclass provides animated scrolling, the start delay should equal the duration of the scrolling animation. The animation starts only if at least one of the scrollbars is enabled, as specified by `isHorizontalScrollBarEnabled()` and `isVerticalScrollBarEnabled()`. When the animation is started, this method returns true, and false otherwise. If the animation is started, this method calls `invalidate()` if the invalidate parameter is set to true; in that case the caller should not call `invalidate()`. This method should be invoked every time a subclass directly updates the scroll parameters.
`Unit`	`bringToFront()` Change the view's z order in the tree, so it's on top of other sibling views. This ordering change may affect layout, if the parent container uses an order-dependent layout scheme (e.g., LinearLayout). Prior to `android.os.Build.VERSION_CODES#KITKAT` this method should be followed by calls to `requestLayout()` and `View#invalidate()` on the view's parent to force the parent to redraw with the new child ordering.
`Unit`	`buildDrawingCache()` Calling this method is equivalent to calling `buildDrawingCache(false)`.
`Unit`	`buildDrawingCache(autoScale: Boolean)` Forces the drawing cache to be built if the drawing cache is invalid. If you call `buildDrawingCache()` manually without calling `setDrawingCacheEnabled(true)`, you should cleanup the cache by calling `destroyDrawingCache()` afterwards. Note about auto scaling in compatibility mode: When auto scaling is not enabled, this method will create a bitmap of the same size as this view. Because this bitmap will be drawn scaled by the parent ViewGroup, the result on screen might show scaling artifacts. To avoid such artifacts, you should call this method by setting the auto scaling to true. Doing so, however, will generate a bitmap of a different size than the view. This implies that your application must be able to handle this size. You should avoid calling this method when hardware acceleration is enabled. If you do not need the drawing cache bitmap, calling this method will increase memory usage and cause the view to be rendered in software once, thus negatively impacting performance.
`Unit`	`buildLayer()` Forces this view's layer to be created and this view to be rendered into its layer. If this view's layer type is set to `LAYER_TYPE_NONE`, invoking this method will have no effect. This method can for instance be used to render a view into its layer before starting an animation. If this view is complex, rendering into the layer before starting the animation will avoid skipping frames.
`Boolean`	`callOnClick()` Directly call any attached OnClickListener. Unlike `performClick()`, this only calls the listener, and does not do any associated clicking actions like reporting an accessibility event.
`Boolean`	`canResolveLayoutDirection()` Check if layout direction resolution can be done.
`Boolean`	`canResolveTextAlignment()` Check if text alignment resolution can be done.
`Boolean`	`canResolveTextDirection()` Check if text direction resolution can be done.
`Boolean`	`canScrollHorizontally(direction: Int)` Check if this view can be scrolled horizontally in a certain direction.
`Boolean`	`canScrollVertically(direction: Int)` Check if this view can be scrolled vertically in a certain direction.
`Unit`	`cancelDragAndDrop()` Cancels an ongoing drag and drop operation. A `android.view.DragEvent` object with `android.view.DragEvent#getAction()` value of `android.view.DragEvent#ACTION_DRAG_ENDED` and `android.view.DragEvent#getResult()` value of `false` will be sent to every View that received `android.view.DragEvent#ACTION_DRAG_STARTED` even if they are not currently visible. This method can be called on any View in the same window as the View on which `startDragAndDrop` was called.
`Unit`	`cancelPendingInputEvents()` Cancel any deferred high-level input events that were previously posted to the event queue. Many views post high-level events such as click handlers to the event queue to run deferred in order to preserve a desired user experience - clearing visible pressed states before executing, etc. This method will abort any events of this nature that are currently in flight. Custom views that generate their own high-level deferred input events should override `onCancelPendingInputEvents()` and remove those pending events from the queue. This will also cancel pending input events for any child views. Note that this may not be sufficient as a debouncing strategy for clicks in all cases. This will not impact newer events posted after this call that may occur as a result of lower-level input events still waiting in the queue. If you are trying to prevent double-submitted events for the duration of some sort of asynchronous transaction you should also take other steps to protect against unexpected double inputs e.g. calling `setEnabled(false)` and re-enabling the view when the transaction completes, tracking already submitted transaction IDs, etc.
`Boolean`	`checkInputConnectionProxy(view: View!)` Called by the `android.view.inputmethod.InputMethodManager` when a view who is not the current input connection target is trying to make a call on the manager. The default implementation returns false; you can override this to return true for certain views if you are performing InputConnection proxying to them.
`Unit`	`clearAnimation()` Cancels any animations for this view.
`Unit`	`clearFocus()` Called when this view wants to give up focus. If focus is cleared `onFocusChanged(boolean,int,android.graphics.Rect)` is called. Note: When not in touch-mode, the framework will try to give focus to the first focusable View from the top after focus is cleared. Hence, if this View is the first from the top that can take focus, then all callbacks related to clearing focus will be invoked after which the framework will give focus to this view.
`Int`	`combineMeasuredStates(curState: Int, newState: Int)` Merge two states as returned by `getMeasuredState()`.
`Int`	`computeHorizontalScrollExtent()` Compute the horizontal extent of the horizontal scrollbar's thumb within the horizontal range. This value is used to compute the length of the thumb within the scrollbar's track. The range is expressed in arbitrary units that must be the same as the units used by `computeHorizontalScrollRange()` and `computeHorizontalScrollOffset()`. The default extent is the drawing width of this view.
`Int`	`computeHorizontalScrollOffset()` Compute the horizontal offset of the horizontal scrollbar's thumb within the horizontal range. This value is used to compute the position of the thumb within the scrollbar's track. The range is expressed in arbitrary units that must be the same as the units used by `computeHorizontalScrollRange()` and `computeHorizontalScrollExtent()`. The default offset is the scroll offset of this view.
`WindowInsets!`	`computeSystemWindowInsets(in: WindowInsets!, outLocalInsets: Rect!)` Compute insets that should be consumed by this view and the ones that should propagate to those under it.
`Int`	`computeVerticalScrollOffset()` Compute the vertical offset of the vertical scrollbar's thumb within the horizontal range. This value is used to compute the position of the thumb within the scrollbar's track. The range is expressed in arbitrary units that must be the same as the units used by `computeVerticalScrollRange()` and `computeVerticalScrollExtent()`. The default offset is the scroll offset of this view.
`AccessibilityNodeInfo!`	`createAccessibilityNodeInfo()` Returns an `AccessibilityNodeInfo` representing this view from the point of view of an `android.accessibilityservice.AccessibilityService`. This method is responsible for obtaining an accessibility node info from a pool of reusable instances and calling `onInitializeAccessibilityNodeInfo(android.view.accessibility.AccessibilityNodeInfo)` on this view to initialize the former. Note: The client is responsible for recycling the obtained instance by calling `AccessibilityNodeInfo#recycle()` to minimize object creation.
`Unit`	`createContextMenu(menu: ContextMenu!)` Show the context menu for this view. It is not safe to hold on to the menu after returning from this method. You should normally not overload this method. Overload `onCreateContextMenu(android.view.ContextMenu)` or define an `OnCreateContextMenuListener` to add items to the context menu.
`Unit`	`destroyDrawingCache()` Frees the resources used by the drawing cache. If you call `buildDrawingCache()` manually without calling `setDrawingCacheEnabled(true)`, you should cleanup the cache with this method afterwards.
`WindowInsets!`	`dispatchApplyWindowInsets(insets: WindowInsets!)` Request to apply the given window insets to this view or another view in its subtree. This method should be called by clients wishing to apply insets corresponding to areas obscured by window decorations or overlays. This can include the status and navigation bars, action bars, input methods and more. New inset categories may be added in the future. The method returns the insets provided minus any that were applied by this view or its children. Clients wishing to provide custom behavior should override the `onApplyWindowInsets(android.view.WindowInsets)` method or alternatively provide a `OnApplyWindowInsetsListener` via the `setOnApplyWindowInsetsListener` method. This method replaces the older `fitSystemWindows` method.
`Boolean`	`dispatchCapturedPointerEvent(event: MotionEvent!)` Pass a captured pointer event down to the focused view.
`Unit`	`dispatchConfigurationChanged(newConfig: Configuration!)` Dispatch a notification about a resource configuration change down the view hierarchy. ViewGroups should override to route to their children.
`Unit`	`dispatchDisplayHint(hint: Int)` Dispatch a hint about whether this view is displayed. For instance, when a View moves out of the screen, it might receives a display hint indicating the view is not displayed. Applications should not rely on this hint as there is no guarantee that they will receive one.
`Boolean`	`dispatchDragEvent(event: DragEvent!)` Detects if this View is enabled and has a drag event listener. If both are true, then it calls the drag event listener with the `android.view.DragEvent` it received. If the drag event listener returns `true`, then dispatchDragEvent() returns `true`. For all other cases, the method calls the `onDragEvent()` drag event handler method and returns its result. This ensures that a drag event is always consumed, even if the View does not have a drag event listener. However, if the View has a listener and the listener returns true, then onDragEvent() is not called.
`Unit`	`dispatchDraw(canvas: Canvas!)` Called by draw to draw the child views. This may be overridden by derived classes to gain control just before its children are drawn (but after its own view has been drawn).
`Unit`	`dispatchDrawableHotspotChanged(x: Float, y: Float)` Dispatches drawableHotspotChanged to all of this View's children.
`Unit`	`dispatchFinishTemporaryDetach()` Dispatch `onFinishTemporaryDetach()` to this View and its direct children if this is a container View. If you override this method you must call through to the superclass implementation.
`Boolean`	`dispatchGenericFocusedEvent(event: MotionEvent!)` Dispatch a generic motion event to the currently focused view. Do not call this method directly. Call `dispatchGenericMotionEvent(android.view.MotionEvent)` instead.
`Boolean`	`dispatchGenericMotionEvent(event: MotionEvent!)` Dispatch a generic motion event. Generic motion events with source class `InputDevice#SOURCE_CLASS_POINTER` are delivered to the view under the pointer. All other generic motion events are delivered to the focused view. Hover events are handled specially and are delivered to `onHoverEvent(android.view.MotionEvent)`.
`Boolean`	`dispatchGenericPointerEvent(event: MotionEvent!)` Dispatch a generic motion event to the view under the first pointer. Do not call this method directly. Call `dispatchGenericMotionEvent(android.view.MotionEvent)` instead.
`Boolean`	`dispatchHoverEvent(event: MotionEvent!)` Dispatch a hover event. Do not call this method directly. Call `dispatchGenericMotionEvent(android.view.MotionEvent)` instead.
`Boolean`	`dispatchKeyEvent(event: KeyEvent!)` Dispatch a key event to the next view on the focus path. This path runs from the top of the view tree down to the currently focused view. If this view has focus, it will dispatch to itself. Otherwise it will dispatch the next node down the focus path. This method also fires any key listeners.
`Boolean`	`dispatchKeyEventPreIme(event: KeyEvent!)` Dispatch a key event before it is processed by any input method associated with the view hierarchy. This can be used to intercept key events in special situations before the IME consumes them; a typical example would be handling the BACK key to update the application's UI instead of allowing the IME to see it and close itself.
`Boolean`	`dispatchKeyShortcutEvent(event: KeyEvent!)` Dispatches a key shortcut event.
`Boolean`	`dispatchNestedFling(velocityX: Float, velocityY: Float, consumed: Boolean)` Dispatch a fling to a nested scrolling parent. This method should be used to indicate that a nested scrolling child has detected suitable conditions for a fling. Generally this means that a touch scroll has ended with a `VelocityTracker` in the direction of scrolling that meets or exceeds the `ViewConfiguration#getScaledMinimumFlingVelocity()` along a scrollable axis. If a nested scrolling child view would normally fling but it is at the edge of its own content, it can use this method to delegate the fling to its nested scrolling parent instead. The parent may optionally consume the fling or observe a child fling.
`Boolean`	`dispatchNestedPreFling(velocityX: Float, velocityY: Float)` Dispatch a fling to a nested scrolling parent before it is processed by this view. Nested pre-fling events are to nested fling events what touch intercept is to touch and what nested pre-scroll is to nested scroll. `dispatchNestedPreFling` offsets an opportunity for the parent view in a nested fling to fully consume the fling before the child view consumes it. If this method returns `true`, a nested parent view consumed the fling and this view should not scroll as a result. For a better user experience, only one view in a nested scrolling chain should consume the fling at a time. If a parent view consumed the fling this method will return false. Custom view implementations should account for this in two ways: If a custom view is paged and needs to settle to a fixed page-point, do not call `dispatchNestedPreFling`; consume the fling and settle to a valid position regardless. If a nested parent does consume the fling, this view should not scroll at all, even to settle back to a valid idle position. Views should also not offer fling velocities to nested parent views along an axis where scrolling is not currently supported; a `ScrollView` should not offer a horizontal fling velocity to its parents since scrolling along that axis is not permitted and carrying velocity along that motion does not make sense.
`Boolean`	`dispatchNestedPrePerformAccessibilityAction(action: Int, arguments: Bundle!)` Report an accessibility action to this view's parents for delegated processing. Implementations of `performAccessibilityAction(int,android.os.Bundle)` may internally call this method to delegate an accessibility action to a supporting parent. If the parent returns true from its `ViewParent#onNestedPrePerformAccessibilityAction(View, int, android.os.Bundle)` method this method will return true to signify that the action was consumed. This method is useful for implementing nested scrolling child views. If `isNestedScrollingEnabled()` returns true and the action is a scrolling action a custom view implementation may invoke this method to allow a parent to consume the scroll first. If this method returns true the custom view should skip its own scrolling behavior.
`Boolean`	`dispatchNestedPreScroll(dx: Int, dy: Int, consumed: IntArray?, offsetInWindow: IntArray?)` Dispatch one step of a nested scroll in progress before this view consumes any portion of it. Nested pre-scroll events are to nested scroll events what touch intercept is to touch. `dispatchNestedPreScroll` offers an opportunity for the parent view in a nested scrolling operation to consume some or all of the scroll operation before the child view consumes it.
`Boolean`	`dispatchNestedScroll(dxConsumed: Int, dyConsumed: Int, dxUnconsumed: Int, dyUnconsumed: Int, offsetInWindow: IntArray?)` Dispatch one step of a nested scroll in progress. Implementations of views that support nested scrolling should call this to report info about a scroll in progress to the current nested scrolling parent. If a nested scroll is not currently in progress or nested scrolling is not `enabled` for this view this method does nothing. Compatible View implementations should also call `dispatchNestedPreScroll` before consuming a component of the scroll event themselves.
`Unit`	`dispatchPointerCaptureChanged(hasCapture: Boolean)`
`Boolean`	`dispatchPopulateAccessibilityEvent(event: AccessibilityEvent!)` Dispatches an `AccessibilityEvent` to the `View` first and then to its children for adding their text content to the event. Note that the event text is populated in a separate dispatch path since we add to the event not only the text of the source but also the text of all its descendants. A typical implementation will call `onPopulateAccessibilityEvent(android.view.accessibility.AccessibilityEvent)` on the this view and then call the `dispatchPopulateAccessibilityEvent(android.view.accessibility.AccessibilityEvent)` on each child. Override this method if custom population of the event text content is required. If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#dispatchPopulateAccessibilityEvent(View, AccessibilityEvent)` is responsible for handling this call. Note: Accessibility events of certain types are not dispatched for populating the event text via this method. For details refer to `AccessibilityEvent`.
`Unit`	`dispatchProvideAutofillStructure(structure: ViewStructure, flags: Int)` Dispatches creation of a `ViewStructure`s for autofill purposes down the hierarchy, when an Assist structure is being created as part of an autofill request. The default implementation does the following: Sets the `AutofillId` in the structure. Calls `onProvideAutofillStructure(android.view.ViewStructure,int)`. Calls `onProvideAutofillVirtualStructure(android.view.ViewStructure,int)`. Typically, this method should only be overridden by subclasses that provide a view hierarchy (such as `ViewGroup`) - other classes should override `onProvideAutofillStructure(android.view.ViewStructure,int)` or `onProvideAutofillVirtualStructure(android.view.ViewStructure,int)` instead. When overridden, it must: Either call `super.dispatchProvideAutofillStructure(structure, flags)` or explicitly set the `AutofillId` in the structure (for example, by calling `structure.setAutofillId(getAutofillId())`). Decide how to handle the `AUTOFILL_FLAG_INCLUDE_NOT_IMPORTANT_VIEWS` flag - when set, all views in the structure should be considered important for autofill, regardless of what `isImportantForAutofill()` returns. We encourage you to respect this flag to provide a better user experience - this flag is typically used when an user explicitly requested autofill. If the flag is not set, then only views marked as important for autofill should be included in the structure - skipping non-important views optimizes the overall autofill performance.
`Unit`	`dispatchProvideStructure(structure: ViewStructure!)` Dispatch creation of `ViewStructure` down the hierarchy. The default implementation calls `onProvideStructure` and `onProvideVirtualStructure`.
`Unit`	`dispatchRestoreInstanceState(container: SparseArray<Parcelable!>!)` Called by `restoreHierarchyState(android.util.SparseArray)` to retrieve the state for this view and its children. May be overridden to modify how restoring happens to a view's children; for example, some views may want to not store state for their children.
`Unit`	`dispatchSaveInstanceState(container: SparseArray<Parcelable!>!)` Called by `saveHierarchyState(android.util.SparseArray)` to store the state for this view and its children. May be overridden to modify how freezing happens to a view's children; for example, some views may want to not store state for their children.
`Unit`	`dispatchSetActivated(activated: Boolean)` Dispatch setActivated to all of this View's children.
`Unit`	`dispatchSetPressed(pressed: Boolean)` Dispatch setPressed to all of this View's children.
`Unit`	`dispatchSetSelected(selected: Boolean)` Dispatch setSelected to all of this View's children.
`Unit`	`dispatchStartTemporaryDetach()` Dispatch `onStartTemporaryDetach()` to this View and its direct children if this is a container View. If you override this method you must call through to the superclass implementation.
`Unit`	`dispatchSystemUiVisibilityChanged(visibility: Int)` Dispatch callbacks to `setOnSystemUiVisibilityChangeListener` down the view hierarchy.
`Boolean`	`dispatchTouchEvent(event: MotionEvent!)` Pass the touch screen motion event down to the target view, or this view if it is the target.
`Boolean`	`dispatchTrackballEvent(event: MotionEvent!)` Pass a trackball motion event down to the focused view.
`Boolean`	`dispatchUnhandledMove(focused: View!, direction: Int)` This method is the last chance for the focused view and its ancestors to respond to an arrow key. This is called when the focused view did not consume the key internally, nor could the view system find a new view in the requested direction to give focus to.
`Unit`	`dispatchVisibilityChanged(changedView: View, visibility: Int)` Dispatch a view visibility change down the view hierarchy. ViewGroups should override to route to their children.
`Unit`	`dispatchWindowFocusChanged(hasFocus: Boolean)` Called when the window containing this view gains or loses window focus. ViewGroups should override to route to their children.
`Unit`	`dispatchWindowSystemUiVisiblityChanged(visible: Int)` Dispatch callbacks to `onWindowSystemUiVisibilityChanged(int)` down the view hierarchy.
`Unit`	`dispatchWindowVisibilityChanged(visibility: Int)` Dispatch a window visibility change down the view hierarchy. ViewGroups should override to route to their children.
`Unit`	`draw(canvas: Canvas!)` Manually render this view (and all of its children) to the given Canvas. The view must have already done a full layout before this function is called. When implementing a view, implement `onDraw(android.graphics.Canvas)` instead of overriding this method. If you do need to override this method, call the superclass version. If you override this method you must call through to the superclass implementation.
`View!`	`findFocus()` Find the view in the hierarchy rooted at this view that currently has focus.
`T`	`findViewById(id: Int)` Finds the first descendant view with the given ID, the view itself if the ID matches `getId()`, or `null` if the ID is invalid (< 0) or there is no matching view in the hierarchy. Note: In most cases -- depending on compiler support -- the resulting view is automatically cast to the target class type. If the target class type is unconstrained, an explicit cast may be necessary.
`T`	`findViewWithTag(tag: Any!)` Look for a child view with the given tag. If this view has the given tag, return this view.
`Boolean`	`fitSystemWindows(insets: Rect!)` Called by the view hierarchy when the content insets for a window have changed, to allow it to adjust its content to fit within those windows. The content insets tell you the space that the status bar, input method, and other system windows infringe on the application's window. You do not normally need to deal with this function, since the default window decoration given to applications takes care of applying it to the content of the window. If you use `SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN` or `SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION` this will not be the case, and your content can be placed under those system elements. You can then use this method within your view hierarchy if you have parts of your UI which you would like to ensure are not being covered. The default implementation of this method simply applies the content insets to the view's padding, consuming that content (modifying the insets to be 0), and returning true. This behavior is off by default, but can be enabled through `setFitsSystemWindows(boolean)`. This function's traversal down the hierarchy is depth-first. The same content insets object is propagated down the hierarchy, so any changes made to it will be seen by all following views (including potentially ones above in the hierarchy since this is a depth-first traversal). The first view that returns true will abort the entire traversal. The default implementation works well for a situation where it is used with a container that covers the entire window, allowing it to apply the appropriate insets to its content on all edges. If you need a more complicated layout (such as two different views fitting system windows, one on the top of the window, and one on the bottom), you can override the method and handle the insets however you would like. Note that the insets provided by the framework are always relative to the far edges of the window, not accounting for the location of the called view within that window. (In fact when this method is called you do not yet know where the layout will place the view, as it is done before layout happens.) Note: unlike many View methods, there is no dispatch phase to this call. If you are overriding it in a ViewGroup and want to allow the call to continue to your children, you must be sure to call the super implementation. Here is a sample layout that makes use of fitting system windows to have controls for a video view placed inside of the window decorations that it hides and shows. This can be used with code like the second sample (video player) shown in `setSystemUiVisibility(int)`. <framelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <view class="com.example.android.apis.view.VideoPlayerActivity$Content" android:id="@+id/content" android:src="@drawable/frantic" android:layout_width="match_parent" android:layout_height="match_parent" android:scaletype="center" /> <framelayout android:layout_width="match_parent" android:layout_height="match_parent" android:fitssystemwindows="true" android:animatelayoutchanges="true"> <textview android:id="@+id/title" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="top\|center_horizontal" android:textcolor="#ffffffff" android:background="#a0000000" android:textappearance="?android:attr/textAppearanceLarge" android:gravity="left" android:padding="16dp" android:text="A title goes here" /> <button android:id="@+id/play" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:gravity="center" android:textsize="28dp"></button> <seekbar android:id="@+id/seekbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom\|center_horizontal" android:layout_marginbottom="16dp" /> </framelayout> </framelayout>
`View!`	`focusSearch(direction: Int)` Find the nearest view in the specified direction that can take focus. This does not actually give focus to that view.
`Unit`	`forceHasOverlappingRendering(hasOverlappingRendering: Boolean)` Sets the behavior for overlapping rendering for this view (see for more details on this behavior). Calling this method is an alternative to overriding `hasOverlappingRendering()` in a subclass, providing the value which is then used internally. That is, when is called, the value of is ignored and the value passed into this method is used instead.
`Unit`	`forceLayout()` Forces this view to be laid out during the next layout pass. This method does not call requestLayout() or forceLayout() on the parent.
`Int`	`generateViewId()` Generate a value suitable for use in `setId(int)`. This value will not collide with ID values generated at build time by aapt for R.id.
`View.AccessibilityDelegate!`	`getAccessibilityDelegate()` Returns the delegate for implementing accessibility support via composition. For more details see `AccessibilityDelegate`.
`Int`	`getAccessibilityLiveRegion()` Gets the live region mode for this View.
`AccessibilityNodeProvider!`	`getAccessibilityNodeProvider()` Gets the provider for managing a virtual view hierarchy rooted at this View and reported to `android.accessibilityservice.AccessibilityService`s that explore the window content. If this method returns an instance, this instance is responsible for managing `AccessibilityNodeInfo`s describing the virtual sub-tree rooted at this View including the one representing the View itself. Similarly the returned instance is responsible for performing accessibility actions on any virtual view or the root view itself. If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#getAccessibilityNodeProvider(View)` is responsible for handling this call.
`CharSequence?`	`getAccessibilityPaneTitle()` Get the title of the pane for purposes of accessibility.
`Int`	`getAccessibilityTraversalAfter()` Gets the id of a view after which this one is visited in accessibility traversal.
`Int`	`getAccessibilityTraversalBefore()` Gets the id of a view before which this one is visited in accessibility traversal.
`Float`	`getAlpha()` The opacity of the view. This is a value from 0 to 1, where 0 means the view is completely transparent and 1 means the view is completely opaque. By default this is 1.0f.
`Animation!`	`getAnimation()` Get the animation currently associated with this view.
`Matrix?`	`getAnimationMatrix()` Return the current transformation matrix of the view. This is used in animation frameworks, such as `android.transition.Transition`. Returns `null` when there is no transformation provided by `setAnimationMatrix(android.graphics.Matrix)`. Application developers should use transformation methods like `setRotation(float)`, `setScaleX(float)`, `setScaleX(float)`, `setTranslationX(float)`} and `setTranslationY(float)` (float)}} instead.
`IBinder!`	`getApplicationWindowToken()` Retrieve a unique token identifying the top-level "real" window of the window that this view is attached to. That is, this is like `getWindowToken`, except if the window this view in is a panel window (attached to another containing window), then the token of the containing window is returned instead.
`IntArray`	`getAttributeResolutionStack(attribute: Int)` Returns the ordered list of resource ID that are considered when resolving attribute values for this `View`. The list will include layout resource ID if the View is inflated from XML. It will also include a set of explicit styles if specified in XML using `style="..."`. Finally, it will include the default styles resolved from the theme. Note: this method will only return actual values if the view attribute debugging is enabled in Android developer options.
`MutableMap<Int!, Int!>`	`getAttributeSourceResourceMap()` Returns the mapping of attribute resource ID to source resource ID where the attribute value was set. Source resource ID can either be a layout resource ID, if the value was set in XML within the View tag, or a style resource ID, if the attribute was set in a style. The source resource value will be one of the resource IDs from `getAttributeSourceResourceMap()`. Note: this method will only return actual values if the view attribute debugging is enabled in Android developer options.
`Array<String!>?`	`getAutofillHints()` Gets the hints that help an `android.service.autofill.AutofillService` determine how to autofill the view with the user's data. See `setAutofillHints(java.lang.String...)` for more info about these hints.
`AutofillId!`	`getAutofillId()` Gets the unique, logical identifier of this view in the activity, for autofill purposes. The autofill id is created on demand, unless it is explicitly set by `setAutofillId(android.view.autofill.AutofillId)`. See `setAutofillId(android.view.autofill.AutofillId)` for more info.
`Drawable!`	`getBackground()` Gets the background drawable
`BlendMode?`	`getBackgroundTintBlendMode()` Return the blending mode used to apply the tint to the background drawable, if specified.
`ColorStateList?`	`getBackgroundTintList()` Return the tint applied to the background drawable, if specified.
`PorterDuff.Mode?`	`getBackgroundTintMode()` Return the blending mode used to apply the tint to the background drawable, if specified.
`Int`	`getBottom()` Bottom position of this view relative to its parent.
`Float`	`getBottomFadingEdgeStrength()` Returns the strength, or intensity, of the bottom faded edge. The strength is a value between 0.0 (no fade) and 1.0 (full fade). The default implementation returns 0.0 or 1.0 but no value in between. Subclasses should override this method to provide a smoother fade transition when scrolling occurs.
`Float`	`getCameraDistance()` Gets the distance along the Z axis from the camera to this view.
`Rect!`	`getClipBounds()` Returns a copy of the current `clipBounds`.
`Boolean`	`getClipBounds(outRect: Rect!)` Populates an output rectangle with the clip bounds of the view, returning `true` if successful or `false` if the view's clip bounds are `null`.
`Boolean`	`getClipToOutline()` Returns whether the Outline should be used to clip the contents of the View. Note that this flag will only be respected if the View's Outline returns true from `Outline#canClip()`.
`ContentCaptureSession?`	`getContentCaptureSession()` Gets the session used to notify content capture events.
`CharSequence!`	`getContentDescription()` Returns the `View`'s content description. Note: Do not override this method, as it will have no effect on the content description presented to accessibility services. You must call `setContentDescription(java.lang.CharSequence)` to modify the content description.
`Context!`	`getContext()` Returns the context the view is running in, through which it can access the current theme, resources, etc.
`ContextMenu.ContextMenuInfo!`	`getContextMenuInfo()` Views should implement this if they have extra information to associate with the context menu. The return result is supplied as a parameter to the `OnCreateContextMenuListener#onCreateContextMenu(ContextMenu, View, ContextMenuInfo)` callback.
`Boolean`	`getDefaultFocusHighlightEnabled()` /** Returns whether this View should use a default focus highlight when it gets focused but doesn't have `android.R.attr#state_focused` defined in its background.
`Int`	`getDefaultSize(size: Int, measureSpec: Int)` Utility to return a default size. Uses the supplied size if the MeasureSpec imposed no constraints. Will get larger if allowed by the MeasureSpec.
`Display!`	`getDisplay()` Gets the logical display to which the view's window has been attached.
`IntArray!`	`getDrawableState()` Return an array of resource IDs of the drawable states representing the current state of the view.
`Bitmap!`	`getDrawingCache()` Calling this method is equivalent to calling `getDrawingCache(false)`.
`Bitmap!`	`getDrawingCache(autoScale: Boolean)` Returns the bitmap in which this view drawing is cached. The returned bitmap is null when caching is disabled. If caching is enabled and the cache is not ready, this method will create it. Calling `draw(android.graphics.Canvas)` will not draw from the cache when the cache is enabled. To benefit from the cache, you must request the drawing cache by calling this method and draw it on screen if the returned bitmap is not null. Note about auto scaling in compatibility mode: When auto scaling is not enabled, this method will create a bitmap of the same size as this view. Because this bitmap will be drawn scaled by the parent ViewGroup, the result on screen might show scaling artifacts. To avoid such artifacts, you should call this method by setting the auto scaling to true. Doing so, however, will generate a bitmap of a different size than the view. This implies that your application must be able to handle this size.
`Int`	`getDrawingCacheBackgroundColor()`
`Int`	`getDrawingCacheQuality()` Returns the quality of the drawing cache.
`Unit`	`getDrawingRect(outRect: Rect!)` Return the visible drawing bounds of your view. Fills in the output rectangle with the values from getScrollX(), getScrollY(), getWidth(), and getHeight(). These bounds do not account for any transformation properties currently set on the view, such as `setScaleX(float)` or `setRotation(float)`.
`Long`	`getDrawingTime()` Return the time at which the drawing of the view hierarchy started.
`Float`	`getElevation()` The base elevation of this view relative to its parent, in pixels.
`Int`	`getExplicitStyle()` Returns the resource ID for the style specified using `style="..."` in the `AttributeSet`'s backing XML element or `Resources#ID_NULL` otherwise if not specified or otherwise not applicable. Each `View` can have an explicit style specified in the layout file. This style is used first during the `View` attribute resolution, then if an attribute is not defined there the resource system looks at default style and theme as fallbacks. Note: this method will only return actual values if the view attribute debugging is enabled in Android developer options.
`Boolean`	`getFilterTouchesWhenObscured()` Gets whether the framework should discard touches when the view's window is obscured by another visible window. Refer to the `View` security documentation for more details.
`Boolean`	`getFitsSystemWindows()` Check for state of `setFitsSystemWindows(boolean)`. If this method returns `true`, the default implementation of `fitSystemWindows(android.graphics.Rect)` will be executed.
`Int`	`getFocusable()` Returns the focusable setting for this view.
`ArrayList<View!>!`	`getFocusables(direction: Int)` Find and return all focusable views that are descendants of this view, possibly including this view if it is focusable itself.
`Drawable!`	`getForeground()` Returns the drawable used as the foreground of this View. The foreground drawable, if non-null, is always drawn on top of the view's content.
`Int`	`getForegroundGravity()` Describes how the foreground is positioned.
`BlendMode?`	`getForegroundTintBlendMode()` Return the blending mode used to apply the tint to the foreground drawable, if specified.
`ColorStateList?`	`getForegroundTintList()` Return the tint applied to the foreground drawable, if specified.
`PorterDuff.Mode?`	`getForegroundTintMode()` Return the blending mode used to apply the tint to the foreground drawable, if specified.
`Boolean`	`getGlobalVisibleRect(r: Rect!, globalOffset: Point!)` If some part of this view is not clipped by any of its parents, then return that area in r in global (root) coordinates. To convert r to local coordinates (without taking possible View rotations into account), offset it by -globalOffset (e.g. r.offset(-globalOffset.x, -globalOffset.y)). If the view is completely clipped or translated out, return false.
`Boolean`	`getGlobalVisibleRect(r: Rect!)`
`Handler!`	`getHandler()`
`Boolean`	`getHasOverlappingRendering()` Returns the value for overlapping rendering that is used internally. This is either the value passed into `forceHasOverlappingRendering(boolean)`, if called, or the return value of `hasOverlappingRendering()`, otherwise.
`Int`	`getHeight()` Return the height of your view.
`Unit`	`getHitRect(outRect: Rect!)` Hit rectangle in parent's coordinates
`Int`	`getHorizontalFadingEdgeLength()` Returns the size of the horizontal faded edges used to indicate that more content in this view is visible.
`Int`	`getHorizontalScrollbarHeight()` Returns the height of the horizontal scrollbar.
`Drawable?`	`getHorizontalScrollbarThumbDrawable()` Returns the currently configured Drawable for the thumb of the horizontal scroll bar if it exists, null otherwise.

`Int`	`getId()` Returns this view's identifier.
`Int`	`getImportantForAccessibility()` Gets the mode for determining whether this View is important for accessibility. A view is important for accessibility if it fires accessibility events and if it is reported to accessibility services that query the screen.
`Int`	`getImportantForAutofill()` Gets the mode for determining whether this view is important for autofill. See `setImportantForAutofill(int)` and `isImportantForAutofill()` for more info about this mode.
`Boolean`	`getKeepScreenOn()` Returns whether the screen should remain on, corresponding to the current value of `KEEP_SCREEN_ON`.
`KeyEvent.DispatcherState!`	`getKeyDispatcherState()` Return the global `KeyEvent.DispatcherState` for this view's window. Returns null if the view is not currently attached to the window. Normally you will not need to use this directly, but just use the standard high-level event callbacks like `onKeyDown(int,android.view.KeyEvent)`.
`Int`	`getLabelFor()` Gets the id of a view for which this view serves as a label for accessibility purposes.
`Int`	`getLayerType()` Indicates what type of layer is currently associated with this view. By default a view does not have a layer, and the layer type is `LAYER_TYPE_NONE`. Refer to the documentation of `setLayerType(int,android.graphics.Paint)` for more information on the different types of layers.
`Int`	`getLayoutDirection()` Returns the resolved layout direction for this view.
`ViewGroup.LayoutParams!`	`getLayoutParams()` Get the LayoutParams associated with this view. All views should have layout parameters. These supply parameters to the parent of this view specifying how it should be arranged. There are many subclasses of ViewGroup.LayoutParams, and these correspond to the different subclasses of ViewGroup that are responsible for arranging their children. This method may return null if this View is not attached to a parent ViewGroup or `setLayoutParams(android.view.ViewGroup.LayoutParams)` was not invoked successfully. When a View is attached to a parent ViewGroup, this method must not return null.
`Int`	`getLeft()` Left position of this view relative to its parent.
`Boolean`	`getLocalVisibleRect(r: Rect!)`
`Unit`	`getLocationInSurface(location: IntArray)` Compute the view's coordinate within the surface. Computes the coordinates of this view in its surface. The argument must be an array of two integers. After the method returns, the array contains the x and y location in that order.
`Unit`	`getLocationInWindow(outLocation: IntArray!)` Computes the coordinates of this view in its window. The argument must be an array of two integers. After the method returns, the array contains the x and y location in that order.
`Unit`	`getLocationOnScreen(outLocation: IntArray!)` Computes the coordinates of this view on the screen. The argument must be an array of two integers. After the method returns, the array contains the x and y location in that order.
`Matrix!`	`getMatrix()` The transform matrix of this view, which is calculated based on the current rotation, scale, and pivot properties.
`Int`	`getMeasuredHeight()` Like `getMeasuredHeightAndState()`, but only returns the raw height component (that is the result is masked by `MEASURED_SIZE_MASK`).
`Int`	`getMeasuredHeightAndState()` Return the full height measurement information for this view as computed by the most recent call to `measure(int,int)`. This result is a bit mask as defined by `MEASURED_SIZE_MASK` and `MEASURED_STATE_TOO_SMALL`. This should be used during measurement and layout calculations only. Use `getHeight()` to see how wide a view is after layout.
`Int`	`getMeasuredState()` Return only the state bits of `getMeasuredWidthAndState()` and `getMeasuredHeightAndState()`, combined into one integer. The width component is in the regular bits `MEASURED_STATE_MASK` and the height component is at the shifted bits `MEASURED_HEIGHT_STATE_SHIFT`>>`MEASURED_STATE_MASK`.
`Int`	`getMeasuredWidth()` Like `getMeasuredWidthAndState()`, but only returns the raw width component (that is the result is masked by `MEASURED_SIZE_MASK`).
`Int`	`getMeasuredWidthAndState()` Return the full width measurement information for this view as computed by the most recent call to `measure(int,int)`. This result is a bit mask as defined by `MEASURED_SIZE_MASK` and `MEASURED_STATE_TOO_SMALL`. This should be used during measurement and layout calculations only. Use `getWidth()` to see how wide a view is after layout.
`Int`	`getMinimumHeight()` Returns the minimum height of the view.

`Int`	`getOutlineAmbientShadowColor()`
`ViewOutlineProvider!`	`getOutlineProvider()` Returns the current `ViewOutlineProvider` of the view, which generates the Outline that defines the shape of the shadow it casts, and enables outline clipping.
`Int`	`getOutlineSpotShadowColor()`
`Int`	`getOverScrollMode()` Returns the over-scroll mode for this view. The result will be one of `OVER_SCROLL_ALWAYS`, `OVER_SCROLL_IF_CONTENT_SCROLLS` (allow over-scrolling only if the view content is larger than the container), or `OVER_SCROLL_NEVER`.
`ViewOverlay!`	`getOverlay()` Returns the overlay for this view, creating it if it does not yet exist. Adding drawables to the overlay will cause them to be displayed whenever the view itself is redrawn. Objects in the overlay should be actively managed: remove them when they should not be displayed anymore. The overlay will always have the same size as its host view. Note: Overlays do not currently work correctly with `SurfaceView` or `TextureView`; contents in overlays for these types of views may not display correctly.
`Int`	`getPaddingBottom()` Returns the bottom padding of this view. If there are inset and enabled scrollbars, this value may include the space required to display the scrollbars as well.
`Int`	`getPaddingEnd()` Returns the end padding of this view depending on its resolved layout direction. If there are inset and enabled scrollbars, this value may include the space required to display the scrollbars as well.
`Int`	`getPaddingLeft()` Returns the left padding of this view. If there are inset and enabled scrollbars, this value may include the space required to display the scrollbars as well.
`Int`	`getPaddingRight()` Returns the right padding of this view. If there are inset and enabled scrollbars, this value may include the space required to display the scrollbars as well.
`Int`	`getPaddingStart()` Returns the start padding of this view depending on its resolved layout direction. If there are inset and enabled scrollbars, this value may include the space required to display the scrollbars as well.
`Int`	`getPaddingTop()` Returns the top padding of this view.
`ViewParent!`	`getParent()` Gets the parent of this view. Note that the parent is a ViewParent and not necessarily a View.
`ViewParent!`	`getParentForAccessibility()` Gets the parent for accessibility purposes. Note that the parent for accessibility is not necessary the immediate parent. It is the first predecessor that is important for accessibility.
`Float`	`getPivotX()` The x location of the point around which the view is `rotated` and `scaled`.
`Float`	`getPivotY()` The y location of the point around which the view is `rotated` and `scaled`.
`PointerIcon!`	`getPointerIcon()` Gets the pointer icon for the current view.
`Resources!`	`getResources()` Returns the resources associated with this view.
`Boolean`	`getRevealOnFocusHint()` Returns this view's preference for reveal behavior when it gains focus. When this method returns true for a child view requesting focus, ancestor views responding to a focus change in `ViewParent#requestChildFocus(View, View)` should make a best effort to make the newly focused child fully visible to the user. When it returns false, ancestor views should preferably not disrupt scroll positioning or other properties affecting visibility to the user as part of the focus change.
`Int`	`getRight()` Right position of this view relative to its parent.
`View!`	`getRootView()` Finds the topmost view in the current view hierarchy.
`WindowInsets!`	`getRootWindowInsets()` Provide original WindowInsets that are dispatched to the view hierarchy. The insets are only available if the view is attached.

`Float`	`getRotationY()` The degrees that the view is rotated around the vertical axis through the pivot point.
`Float`	`getScaleX()` The amount that the view is scaled in x around the pivot point, as a proportion of the view's unscaled width. A value of 1, the default, means that no scaling is applied. By default, this is 1.0f.
`Float`	`getScaleY()` The amount that the view is scaled in y around the pivot point, as a proportion of the view's unscaled height. A value of 1, the default, means that no scaling is applied. By default, this is 1.0f.

`Int`	`getScrollBarFadeDuration()` Returns the scrollbar fade duration.
`Int`	`getScrollBarSize()` Returns the scrollbar size.
`Int`	`getScrollBarStyle()` Returns the current scrollbar style.
`Int`	`getScrollIndicators()` Returns a bitmask representing the enabled scroll indicators. For example, if the top and left scroll indicators are enabled and all other indicators are disabled, the return value will be `View.SCROLL_INDICATOR_TOP \| View.SCROLL_INDICATOR_LEFT`. To check whether the bottom scroll indicator is enabled, use the value of `(getScrollIndicators() & View.SCROLL_INDICATOR_BOTTOM) != 0`.
`Int`	`getScrollX()` Return the scrolled left position of this view. This is the left edge of the displayed part of your view. You do not need to draw any pixels farther left, since those are outside of the frame of your view on screen.
`Int`	`getScrollY()` Return the scrolled top position of this view. This is the top edge of the displayed part of your view. You do not need to draw any pixels above it, since those are outside of the frame of your view on screen.
`Int`	`getSolidColor()` Override this if your view is known to always be drawn on top of a solid color background, and needs to draw fading edges. Returning a non-zero color enables the view system to optimize the drawing of the fading edges. If you do return a non-zero color, the alpha should be set to 0xFF.
`Int`	`getSourceLayoutResId()` A `View` can be inflated from an XML layout. For such Views this method returns the resource ID of the source layout.
`StateListAnimator!`	`getStateListAnimator()` Returns the current StateListAnimator if exists.
`Int`	`getSuggestedMinimumHeight()` Returns the suggested minimum height that the view should use. This returns the maximum of the view's minimum height and the background's minimum height (`android.graphics.drawable.Drawable#getMinimumHeight()`). When being used in `onMeasure(int,int)`, the caller should still ensure the returned height is within the requirements of the parent.
`Int`	`getSuggestedMinimumWidth()` Returns the suggested minimum width that the view should use. This returns the maximum of the view's minimum width and the background's minimum width (`android.graphics.drawable.Drawable#getMinimumWidth()`). When being used in `onMeasure(int,int)`, the caller should still ensure the returned width is within the requirements of the parent.
`MutableList<Rect!>`	`getSystemGestureExclusionRects()` Retrieve the list of areas within this view's post-layout coordinate space where the system should not intercept touch or other pointing device gestures. Do not modify the returned list.

`Int`	`getTextAlignment()` Return the resolved text alignment.
`Int`	`getTextDirection()` Return the resolved text direction.
`CharSequence?`	`getTooltipText()` Returns the view's tooltip text. Note: Do not override this method, as it will have no effect on the text displayed in the tooltip. You must call `setTooltipText(java.lang.CharSequence)` to modify the tooltip text.
`Int`	`getTop()` Top position of this view relative to its parent.
`Float`	`getTopFadingEdgeStrength()` Returns the strength, or intensity, of the top faded edge. The strength is a value between 0.0 (no fade) and 1.0 (full fade). The default implementation returns 0.0 or 1.0 but no value in between. Subclasses should override this method to provide a smoother fade transition when scrolling occurs.
`TouchDelegate!`	`getTouchDelegate()` Gets the TouchDelegate for this View.
`ArrayList<View!>!`	`getTouchables()` Find and return all touchable views that are descendants of this view, possibly including this view if it is touchable itself.
`Float`	`getTransitionAlpha()` This property is intended only for use by the Fade transition, which animates it to produce a visual translucency that does not side-effect (or get affected by) the real alpha property. This value is composited with the other alpha value (and the AlphaAnimation value, when that is present) to produce a final visual translucency result, which is what is passed into the DisplayList.
`String!`	`getTransitionName()` Returns the name of the View to be used to identify Views in Transitions. Names should be unique in the View hierarchy. This returns null if the View has not been given a name.
`Float`	`getTranslationX()` The horizontal location of this view relative to its `left` position. This position is post-layout, in addition to wherever the object's layout placed it.
`Float`	`getTranslationY()` The vertical location of this view relative to its `top` position. This position is post-layout, in addition to wherever the object's layout placed it.

`Drawable?`	`getVerticalScrollbarTrackDrawable()` Returns the currently configured Drawable for the track of the vertical scroll bar if it exists, null otherwise.
`Int`	`getVerticalScrollbarWidth()` Returns the width of the vertical scrollbar.
`ViewTreeObserver!`	`getViewTreeObserver()` Returns the ViewTreeObserver for this view's hierarchy. The view tree observer can be used to get notifications when global events, like layout, happen. The returned ViewTreeObserver observer is not guaranteed to remain valid for the lifetime of this View. If the caller of this method keeps a long-lived reference to ViewTreeObserver, it should always check for the return value of `ViewTreeObserver#isAlive()`.
`Int`	`getVisibility()` Returns the visibility status for this view.
`Int`	`getWidth()` Return the width of your view.
`Int`	`getWindowAttachCount()`
`WindowId!`	`getWindowId()` Retrieve the `WindowId` for the window this view is currently attached to.
`Int`	`getWindowSystemUiVisibility()` Returns the current system UI visibility that is currently set for the entire window. This is the combination of the `setSystemUiVisibility(int)` values supplied by all of the views in the window.
`IBinder!`	`getWindowToken()` Retrieve a unique token identifying the window this view is attached to.
`Int`	`getWindowVisibility()` Returns the current visibility of the window this view is attached to (either `GONE`, `INVISIBLE`, or `VISIBLE`).
`Unit`	`getWindowVisibleDisplayFrame(outRect: Rect!)` Retrieve the overall visible display size in which the window this view is attached to has been positioned in. This takes into account screen decorations above the window, for both cases where the window itself is being position inside of them or the window is being placed under then and covered insets are used for the window to position its content inside. In effect, this tells you the available area where content can be placed and remain visible to users. This function requires an IPC back to the window manager to retrieve the requested information, so should not be used in performance critical code like drawing.
`Float`	`getX()` The visual x position of this view, in pixels. This is equivalent to the `translationX` property plus the current `left` property.
`Float`	`getY()` The visual y position of this view, in pixels. This is equivalent to the `translationY` property plus the current `top` property.
`Float`	`getZ()` The visual z position of this view, in pixels. This is equivalent to the `translationZ` property plus the current `elevation` property.
`Boolean`	`hasExplicitFocusable()` Returns true if this view is focusable or if it contains a reachable View for which `hasExplicitFocusable()` returns `true`. A "reachable hasExplicitFocusable()" is a view whose parents do not block descendants focus. Only `VISIBLE` views for which `getFocusable()` would return `FOCUSABLE` are considered focusable. This method preserves the pre-`Build.VERSION_CODES#O` behavior of `hasFocusable()` in that only views explicitly set focusable will cause this method to return true. A view set to `FOCUSABLE_AUTO` that resolves to focusable will not.
`Boolean`	`hasFocus()` Returns true if this view has focus itself, or is the ancestor of the view that has focus.
`Boolean`	`hasFocusable()` Returns true if this view is focusable or if it contains a reachable View for which `hasFocusable()` returns `true`. A "reachable hasFocusable()" is a view whose parents do not block descendants focus. Only `VISIBLE` views are considered focusable. As of `Build.VERSION_CODES#O` views that are determined to be focusable through `FOCUSABLE_AUTO` will also cause this method to return `true`. Apps that declare a `android.content.pm.ApplicationInfo#targetSdkVersion` of earlier than `Build.VERSION_CODES#O` will continue to see this method return `false` for views not explicitly marked as focusable. Use `hasExplicitFocusable()` if you require the pre-`Build.VERSION_CODES#O` behavior.
`Boolean`	`hasNestedScrollingParent()` Returns true if this view has a nested scrolling parent. The presence of a nested scrolling parent indicates that this view has initiated a nested scroll and it was accepted by an ancestor view further up the view hierarchy.
`Boolean`	`hasOnClickListeners()` Return whether this view has an attached OnClickListener. Returns true if there is a listener, false if there is none.
`Boolean`	`hasPointerCapture()` Checks pointer capture status.
`Boolean`	`hasTransientState()` Indicates whether the view is currently tracking transient state that the app should not need to concern itself with saving and restoring, but that the framework should take special note to preserve when possible. A view with transient state cannot be trivially rebound from an external data source, such as an adapter binding item views in a list. This may be because the view is performing an animation, tracking user selection of content, or similar.
`Boolean`	`hasWindowFocus()` Returns true if this view is in a window that currently has window focus. Note that this is not the same as the view itself having focus.
`View!`	`inflate(context: Context!, resource: Int, root: ViewGroup!)` Inflate a view from an XML resource. This convenience method wraps the `LayoutInflater` class, which provides a full range of options for view inflation.
`Unit`	`invalidate(dirty: Rect!)` Mark the area defined by dirty as needing to be drawn. If the view is visible, `onDraw(android.graphics.Canvas)` will be called at some point in the future. This must be called from a UI thread. To call from a non-UI thread, call `postInvalidate()`. WARNING: In API 19 and below, this method may be destructive to `dirty`.
`Unit`	`invalidate(l: Int, t: Int, r: Int, b: Int)` Mark the area defined by the rect (l,t,r,b) as needing to be drawn. The coordinates of the dirty rect are relative to the view. If the view is visible, `onDraw(android.graphics.Canvas)` will be called at some point in the future. This must be called from a UI thread. To call from a non-UI thread, call `postInvalidate()`.
`Unit`	`invalidate()` Invalidate the whole view. If the view is visible, `onDraw(android.graphics.Canvas)` will be called at some point in the future. This must be called from a UI thread. To call from a non-UI thread, call `postInvalidate()`.
`Unit`	`invalidateOutline()` Called to rebuild this View's Outline from its `ViewOutlineProvider`
`Boolean`	`isAccessibilityFocused()` Returns whether this View is accessibility focused.
`Boolean`	`isAccessibilityHeading()` Gets whether this view is a heading for accessibility purposes.
`Boolean`	`isActivated()` Indicates the activation state of this view.
`Boolean`	`isAttachedToWindow()` Returns true if this view is currently attached to a window.
`Boolean`	`isClickable()` Indicates whether this view reacts to click events or not.
`Boolean`	`isContextClickable()` Indicates whether this view reacts to context clicks or not.
`Boolean`	`isDirty()` True if this view has changed since the last time being drawn.
`Boolean`	`isDrawingCacheEnabled()` Indicates whether the drawing cache is enabled for this view.
`Boolean`	`isDuplicateParentStateEnabled()` Indicates whether this duplicates its drawable state from its parent.
`Boolean`	`isEnabled()` Returns the enabled status for this view. The interpretation of the enabled state varies by subclass.
`Boolean`	`isFocusable()` Returns whether this View is currently able to take focus.
`Boolean`	`isFocusableInTouchMode()` When a view is focusable, it may not want to take focus when in touch mode. For example, a button would like focus when the user is navigating via a D-pad so that the user can click on it, but once the user starts touching the screen, the button shouldn't take focus
`Boolean`	`isFocused()` Returns true if this view has focus
`Boolean`	`isFocusedByDefault()` Returns whether this View should receive focus when the focus is restored for the view hierarchy containing this view. Focus gets restored for a view hierarchy when the root of the hierarchy gets added to a window or serves as a target of cluster navigation.
`Boolean`	`isForceDarkAllowed()` See `setForceDarkAllowed(boolean)`
`Boolean`	`isHapticFeedbackEnabled()`
`Boolean`	`isHardwareAccelerated()` Indicates whether this view is attached to a hardware accelerated window or not. Even if this method returns true, it does not mean that every call to `draw(android.graphics.Canvas)` will be made with an hardware accelerated `android.graphics.Canvas`. For instance, if this view is drawn onto an offscreen `android.graphics.Bitmap` and its window is hardware accelerated, `android.graphics.Canvas#isHardwareAccelerated()` will likely return false, and this method will return true.
`Boolean`	`isHorizontalFadingEdgeEnabled()` Indicate whether the horizontal edges are faded when the view is scrolled horizontally.
`Boolean`	`isHorizontalScrollBarEnabled()` Indicate whether the horizontal scrollbar should be drawn or not. The scrollbar is not drawn by default.
`Boolean`	`isHovered()` Returns true if the view is currently hovered.
`Boolean`	`isImportantForAccessibility()` Computes whether this view should be exposed for accessibility. In general, views that are interactive or provide information are exposed while views that serve only as containers are hidden. If an ancestor of this view has importance `IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS`, this method returns `false`. Otherwise, the value is computed according to the view's `getImportantForAccessibility()` value: `IMPORTANT_FOR_ACCESSIBILITY_NO` or `IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS`, return `false` `IMPORTANT_FOR_ACCESSIBILITY_YES`, return `true` `IMPORTANT_FOR_ACCESSIBILITY_AUTO`, return `true` if view satisfies any of the following: Is actionable, e.g. `isClickable()`, `isLongClickable()`, or `isFocusable()` Has an `AccessibilityDelegate` Has an interaction listener, e.g. `OnTouchListener`, `OnKeyListener`, etc. Is an accessibility live region, e.g. `getAccessibilityLiveRegion()` is not `ACCESSIBILITY_LIVE_REGION_NONE`. Has an accessibility pane title, see `setAccessibilityPaneTitle`
`Boolean`	`isImportantForAutofill()` Hints the Android System whether the `android.app.assist.AssistStructure.ViewNode` associated with this view is considered important for autofill purposes. Generally speaking, a view is important for autofill if: The view can be autofilled by an `android.service.autofill.AutofillService`. The view contents can help an `android.service.autofill.AutofillService` determine how other views can be autofilled. For example, view containers should typically return `false` for performance reasons (since the important info is provided by their children), but if its properties have relevant information (for example, a resource id called `credentials`, it should return `true`. On the other hand, views representing labels or editable fields should typically return `true`, but in some cases they could return `false` (for example, if they're part of a "Captcha" mechanism). The value returned by this method depends on the value returned by `getImportantForAutofill()`: if it returns `IMPORTANT_FOR_AUTOFILL_YES` or `IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS`, then it returns `true` if it returns `IMPORTANT_FOR_AUTOFILL_NO` or `IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS`, then it returns `false` if it returns `IMPORTANT_FOR_AUTOFILL_AUTO`, then it uses some simple heuristics that can return `true` in some cases (like a container with a resource id), but `false` in most. otherwise, it returns `false`. When a view is considered important for autofill: The view might automatically trigger an autofill request when focused on. The contents of the view are included in the `ViewStructure` used in an autofill request. On the other hand, when a view is considered not important for autofill: The view never automatically triggers autofill requests, but it can trigger a manual request through `AutofillManager#requestAutofill(View)`. The contents of the view are not included in the `ViewStructure` used in an autofill request, unless the request has the `AUTOFILL_FLAG_INCLUDE_NOT_IMPORTANT_VIEWS` flag.
`Boolean`	`isInEditMode()` Indicates whether this View is currently in edit mode. A View is usually in edit mode when displayed within a developer tool. For instance, if this View is being drawn by a visual user interface builder, this method should return true. Subclasses should check the return value of this method to provide different behaviors if their normal behavior might interfere with the host environment. For instance: the class spawns a thread in its constructor, the drawing code relies on device-specific features, etc. This method is usually checked in the drawing code of custom widgets.
`Boolean`	`isInLayout()` Returns whether the view hierarchy is currently undergoing a layout pass. This information is useful to avoid situations such as calling `requestLayout()` during a layout pass.
`Boolean`	`isInTouchMode()` Returns whether the device is currently in touch mode. Touch mode is entered once the user begins interacting with the device by touch, and affects various things like whether focus is always visible to the user.
`Boolean`	`isKeyboardNavigationCluster()` Returns whether this View is a root of a keyboard navigation cluster.
`Boolean`	`isLaidOut()` Returns true if this view has been through at least one layout since it was last attached to or detached from a window.
`Boolean`	`isLayoutDirectionResolved()`
`Boolean`	`isLayoutRequested()` Indicates whether or not this view's layout will be requested during the next hierarchy layout pass.
`Boolean`	`isLongClickable()` Indicates whether this view reacts to long click events or not.
`Boolean`	`isNestedScrollingEnabled()` Returns true if nested scrolling is enabled for this view. If nested scrolling is enabled and this View class implementation supports it, this view will act as a nested scrolling child view when applicable, forwarding data about the scroll operation in progress to a compatible and cooperating nested scrolling parent.
`Boolean`	`isOpaque()` Indicates whether this View is opaque. An opaque View guarantees that it will draw all the pixels overlapping its bounds using a fully opaque color. Subclasses of View should override this method whenever possible to indicate whether an instance is opaque. Opaque Views are treated in a special way by the View hierarchy, possibly allowing it to perform optimizations during invalidate/draw passes.
`Boolean`	`isPaddingRelative()` Return if the padding has been set through relative values `setPaddingRelative(int,int,int,int)` or through
`Boolean`	`isPivotSet()` Returns whether or not a pivot has been set by a call to `setPivotX(float)` or `setPivotY(float)`. If no pivot has been set then the pivot will be the center of the view.
`Boolean`	`isPressed()` Indicates whether the view is currently in pressed state. Unless `setPressed(boolean)` is explicitly called, only clickable views can enter the pressed state.
`Boolean`	`isSaveEnabled()` Indicates whether this view will save its state (that is, whether its `onSaveInstanceState` method will be called).
`Boolean`	`isSaveFromParentEnabled()` Indicates whether the entire hierarchy under this view will save its state when a state saving traversal occurs from its parent. The default is true; if false, these views will not be saved unless `saveHierarchyState(android.util.SparseArray)` is called directly on this view.
`Boolean`	`isScreenReaderFocusable()` Returns whether the view should be treated as a focusable unit by screen reader accessibility tools.
`Boolean`	`isScrollContainer()` Indicates whether this view is one of the set of scrollable containers in its window.
`Boolean`	`isScrollbarFadingEnabled()` Returns true if scrollbars will fade when this view is not scrolling
`Boolean`	`isSelected()` Indicates the selection state of this view.
`Boolean`	`isShown()` Returns the visibility of this view and all of its ancestors
`Boolean`	`isSoundEffectsEnabled()`
`Boolean`	`isTemporarilyDetached()` Tells whether the `View` is in the state between `onStartTemporaryDetach()` and `onFinishTemporaryDetach()`. This method always returns `true` when called directly or indirectly from `onStartTemporaryDetach()`. The return value when called directly or indirectly from `onFinishTemporaryDetach()`, however, depends on the OS version. `true` on `API 24` `false` on `API 25`} and later
`Boolean`	`isTextAlignmentResolved()`
`Boolean`	`isTextDirectionResolved()`
`Boolean`	`isVerticalFadingEdgeEnabled()` Indicate whether the vertical edges are faded when the view is scrolled horizontally.
`Boolean`	`isVerticalScrollBarEnabled()` Indicate whether the vertical scrollbar should be drawn or not. The scrollbar is not drawn by default.
`Boolean`	`isVisibleToUserForAutofill(virtualId: Int)` Computes whether this virtual autofill view is visible to the user. Note: By default it returns `true`, but views providing a virtual hierarchy view must override it.
`View!`	`keyboardNavigationClusterSearch(currentCluster: View!, direction: Int)` Find the nearest keyboard navigation cluster in the specified direction. This does not actually give focus to that cluster.
`Unit`	`layout(l: Int, t: Int, r: Int, b: Int)` Assign a size and position to a view and all of its descendants This is the second phase of the layout mechanism. (The first is measuring). In this phase, each parent calls layout on all of its children to position them. This is typically done using the child measurements that were stored in the measure pass(). Derived classes should not override this method. Derived classes with children should override onLayout. In that method, they should call layout on each of their children.
`Unit`	`measure(widthMeasureSpec: Int, heightMeasureSpec: Int)` This is called to find out how big a view should be. The parent supplies constraint information in the width and height parameters. The actual measurement work of a view is performed in `onMeasure(int,int)`, called by this method. Therefore, only `onMeasure(int,int)` can and must be overridden by subclasses.
`IntArray!`	`mergeDrawableStates(baseState: IntArray!, additionalState: IntArray!)` Merge your own state values in additionalState into the base state values baseState that were returned by `onCreateDrawableState(int)`.
`Unit`	`offsetLeftAndRight(offset: Int)` Offset this view's horizontal location by the specified amount of pixels.
`Unit`	`offsetTopAndBottom(offset: Int)` Offset this view's vertical location by the specified number of pixels.
`Unit`	`onAnimationEnd()` Invoked by a parent ViewGroup to notify the end of the animation currently associated with this view. If you override this method, always call super.onAnimationEnd(); If you override this method you must call through to the superclass implementation.
`Unit`	`onAnimationStart()` Invoked by a parent ViewGroup to notify the start of the animation currently associated with this view. If you override this method, always call super.onAnimationStart(); If you override this method you must call through to the superclass implementation.
`WindowInsets!`	`onApplyWindowInsets(insets: WindowInsets!)` Called when the view should apply `WindowInsets` according to its internal policy. This method should be overridden by views that wish to apply a policy different from or in addition to the default behavior. Clients that wish to force a view subtree to apply insets should call `dispatchApplyWindowInsets(android.view.WindowInsets)`. Clients may supply an `OnApplyWindowInsetsListener` to a view. If one is set it will be called during dispatch instead of this method. The listener may optionally call this method from its own implementation if it wishes to apply the view's default insets policy in addition to its own. Implementations of this method should either return the insets parameter unchanged or a new `WindowInsets` cloned from the supplied insets with any insets consumed that this view applied itself. This allows new inset types added in future platform versions to pass through existing implementations unchanged without being erroneously consumed. By default if a view's `fitsSystemWindows` property is set then the view will consume the system window insets and apply them as padding for the view.
`Unit`	`onCancelPendingInputEvents()` Called as the result of a call to `cancelPendingInputEvents()` on this view or a parent view. This method is responsible for removing any pending high-level input events that were posted to the event queue to run later. Custom view classes that post their own deferred high-level events via `post(java.lang.Runnable)`, `postDelayed(java.lang.Runnable,long)` or `android.os.Handler` should override this method, call `super.onCancelPendingInputEvents()` and remove those callbacks as appropriate.
`Boolean`	`onCapturedPointerEvent(event: MotionEvent!)` Implement this method to handle captured pointer events
`Unit`	`onDetachedFromWindow()` This is called when the view is detached from a window. At this point it no longer has a surface for drawing. If you override this method you must call through to the superclass implementation.
`Unit`	`onDisplayHint(hint: Int)` Gives this view a hint about whether is displayed or not. For instance, when a View moves out of the screen, it might receives a display hint indicating the view is not displayed. Applications should not rely on this hint as there is no guarantee that they will receive one.
`Unit`	`onDrawForeground(canvas: Canvas!)` Draw any foreground content for this view. Foreground content may consist of scroll bars, a `foreground` drawable or other view-specific decorations. The foreground is drawn on top of the primary view content.
`Unit`	`onDrawScrollBars(canvas: Canvas!)` Request the drawing of the horizontal and the vertical scrollbar. The scrollbars are painted only if they have been awakened first.
`Boolean`	`onFilterTouchEventForSecurity(event: MotionEvent!)` Filter the touch event to apply security policies.
`Unit`	`onFinishInflate()` Finalize inflating a view from XML. This is called as the last phase of inflation, after all child views have been added. Even if the subclass overrides onFinishInflate, they should always be sure to call the super method, so that we get called. If you override this method you must call through to the superclass implementation.
`Unit`	`onFinishTemporaryDetach()` Called after `onStartTemporaryDetach` when the container is done changing the view.
`Unit`	`onHoverChanged(hovered: Boolean)` Implement this method to handle hover state changes. This method is called whenever the hover state changes as a result of a call to `setHovered`.
`Boolean`	`onHoverEvent(event: MotionEvent!)` Implement this method to handle hover events. This method is called whenever a pointer is hovering into, over, or out of the bounds of a view and the view is not currently being touched. Hover events are represented as pointer events with action `MotionEvent#ACTION_HOVER_ENTER`, `MotionEvent#ACTION_HOVER_MOVE`, or `MotionEvent#ACTION_HOVER_EXIT`. The view receives a hover event with action `MotionEvent#ACTION_HOVER_ENTER` when the pointer enters the bounds of the view. The view receives a hover event with action `MotionEvent#ACTION_HOVER_MOVE` when the pointer has already entered the bounds of the view and has moved. The view receives a hover event with action `MotionEvent#ACTION_HOVER_EXIT` when the pointer has exited the bounds of the view or when the pointer is about to go down due to a button click, tap, or similar user action that causes the view to be touched. The view should implement this method to return true to indicate that it is handling the hover event, such as by changing its drawable state. The default implementation calls `setHovered` to update the hovered state of the view when a hover enter or hover exit event is received, if the view is enabled and is clickable. The default implementation also sends hover accessibility events.
`Unit`	`onInitializeAccessibilityEvent(event: AccessibilityEvent!)` Initializes an `AccessibilityEvent` with information about this View which is the event source. In other words, the source of an accessibility event is the view whose state change triggered firing the event. Example: Setting the password property of an event in addition to properties set by the super implementation: public void onInitializeAccessibilityEvent(AccessibilityEvent event) { super.onInitializeAccessibilityEvent(event); event.setPassword(true); } If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#onInitializeAccessibilityEvent(View, AccessibilityEvent)` is responsible for handling this call. Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add. If you override this method you must call through to the superclass implementation.
`Unit`	`onInitializeAccessibilityNodeInfo(info: AccessibilityNodeInfo!)` Initializes an `AccessibilityNodeInfo` with information about this view. The base implementation sets: `AccessibilityNodeInfo#setParent(View)`, `AccessibilityNodeInfo#setBoundsInParent(Rect)`, `AccessibilityNodeInfo#setBoundsInScreen(Rect)`, `AccessibilityNodeInfo#setPackageName(CharSequence)`, `AccessibilityNodeInfo#setClassName(CharSequence)`, `AccessibilityNodeInfo#setContentDescription(CharSequence)`, `AccessibilityNodeInfo#setEnabled(boolean)`, `AccessibilityNodeInfo#setClickable(boolean)`, `AccessibilityNodeInfo#setFocusable(boolean)`, `AccessibilityNodeInfo#setFocused(boolean)`, `AccessibilityNodeInfo#setLongClickable(boolean)`, `AccessibilityNodeInfo#setSelected(boolean)`, `AccessibilityNodeInfo#setContextClickable(boolean)` Subclasses should override this method, call the super implementation, and set additional attributes. If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo)` is responsible for handling this call. If you override this method you must call through to the superclass implementation.
`Boolean`	`onKeyLongPress(keyCode: Int, event: KeyEvent!)` Default implementation of `KeyEvent.Callback#onKeyLongPress(int, KeyEvent)`: always returns false (doesn't handle the event). Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.
`Unit`	`onOverScrolled(scrollX: Int, scrollY: Int, clampedX: Boolean, clampedY: Boolean)` Called by `overScrollBy(int,int,int,int,int,int,int,int,boolean)` to respond to the results of an over-scroll operation.
`Unit`	`onPointerCaptureChange(hasCapture: Boolean)` Called when the window has just acquired or lost pointer capture. If you override this method you must call through to the superclass implementation.
`Unit`	`onPopulateAccessibilityEvent(event: AccessibilityEvent!)` Called from `dispatchPopulateAccessibilityEvent(android.view.accessibility.AccessibilityEvent)` giving a chance to this View to populate the accessibility event with its text content. While this method is free to modify event attributes other than text content, doing so should normally be performed in `onInitializeAccessibilityEvent(android.view.accessibility.AccessibilityEvent)`. Example: Adding formatted date string to an accessibility event in addition to the text added by the super implementation: public void onPopulateAccessibilityEvent(AccessibilityEvent event) { super.onPopulateAccessibilityEvent(event); final int flags = DateUtils.FORMAT_SHOW_DATE \| DateUtils.FORMAT_SHOW_WEEKDAY; String selectedDateUtterance = DateUtils.formatDateTime(mContext, mCurrentDate.getTimeInMillis(), flags); event.getText().add(selectedDateUtterance); } If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#onPopulateAccessibilityEvent(View, AccessibilityEvent)` is responsible for handling this call. Note: Always call the super implementation before adding information to the event, in case the default implementation has basic information to add. If you override this method you must call through to the superclass implementation.
`Unit`	`onProvideAutofillStructure(structure: ViewStructure!, flags: Int)` Populates a `ViewStructure` to fullfil an autofill request. The structure should contain at least the following properties: Autofill id (`ViewStructure#setAutofillId(AutofillId, int)`). Autofill type (`ViewStructure#setAutofillType(int)`). Autofill value (`ViewStructure#setAutofillValue(AutofillValue)`). Whether the data is sensitive (`ViewStructure#setDataIsSensitive(boolean)`). It's also recommended to set the following properties - the more properties the structure has, the higher the changes of an `android.service.autofill.AutofillService` properly using the structure: Autofill hints (`ViewStructure#setAutofillHints(String[])`). Autofill options (`ViewStructure#setAutofillOptions(CharSequence[])`) when the view can only be filled with predefined values (typically used when the autofill type is `AUTOFILL_TYPE_LIST`). Resource id (`ViewStructure#setId(int, String, String, String)`). Class name (`ViewStructure#setClassName(String)`). Content description (`ViewStructure#setContentDescription(CharSequence)`). Visual properties such as visibility (`ViewStructure#setVisibility(int)`), dimensions (`ViewStructure#setDimens(int, int, int, int, int, int)`), and opacity (`ViewStructure#setOpaque(boolean)`). For views representing text fields, text properties such as the text itself (`ViewStructure#setText(CharSequence)`), text hints (`ViewStructure#setHint(CharSequence)`, input type (`ViewStructure#setInputType(int)`), For views representing HTML nodes, its web domain (`ViewStructure#setWebDomain(String)`) and HTML properties ((`ViewStructure#setHtmlInfo(android.view.ViewStructure.HtmlInfo)`). The default implementation of this method already sets most of these properties based on related `View` methods (for example, the autofill id is set using `getAutofillId()`, the autofill type set using `getAutofillType()`, etc.), and views in the standard Android widgets library also override it to set their relevant properties (for example, `android.widget.TextView` already sets the text properties), so it's recommended to only override this method (and call `super.onProvideAutofillStructure()`) when: The view contents does not include PII (Personally Identifiable Information), so it can call `ViewStructure#setDataIsSensitive(boolean)` passing `false`. The view can only be autofilled with predefined options, so it can call `ViewStructure#setAutofillOptions(CharSequence[])`. Note: The `left` and `top` values set in `ViewStructure#setDimens(int, int, int, int, int, int)` must be relative to the next `ViewGroup#isImportantForAutofill()` predecessor view included in the structure. Views support the Autofill Framework mainly by: Providing the metadata defining what the view means and how it can be autofilled. Notifying the Android System when the view value changed by calling `AutofillManager#notifyValueChanged(View)`. Implementing the methods that autofill the view. This method is responsible for the former; `autofill(android.view.autofill.AutofillValue)` is responsible for the latter.
`Unit`	`onProvideAutofillVirtualStructure(structure: ViewStructure!, flags: Int)` Populates a `ViewStructure` containing virtual children to fullfil an autofill request. This method should be used when the view manages a virtual structure under this view. For example, a view that draws input fields using `draw(android.graphics.Canvas)`. When implementing this method, subclasses must follow the rules below: Add virtual children by calling the `ViewStructure#newChild(int)` or `ViewStructure#asyncNewChild(int)` methods, where the `id` is an unique id identifying the children in the virtual structure. The children hierarchy can have multiple levels if necessary, but ideally it should exclude intermediate levels that are irrelevant for autofill; that would improve the autofill performance. Also implement `autofill(android.util.SparseArray)` to autofill the virtual children. Set the autofill properties of the child structure as defined by `onProvideAutofillStructure(android.view.ViewStructure,int)`, using `ViewStructure#setAutofillId(AutofillId, int)` to set its autofill id. Call `android.view.autofill.AutofillManager#notifyViewEntered(View, int, Rect)` and/or `android.view.autofill.AutofillManager#notifyViewExited(View, int)` when the focused virtual child changed. Override `isVisibleToUserForAutofill(int)` to allow the platform to query whether a given virtual view is visible to the user in order to support triggering save when all views of interest go away. Call `android.view.autofill.AutofillManager#notifyValueChanged(View, int, AutofillValue)` when the value of a virtual child changed. Call when the visibility of a virtual child changed. Call `android.view.autofill.AutofillManager#notifyViewClicked(View, int)` when a virtual child is clicked. Call `AutofillManager#commit()` when the autofill context of the view structure changed and the current context should be committed (for example, when the user tapped a `SUBMIT` button in an HTML page). Call `AutofillManager#cancel()` when the autofill context of the view structure changed and the current context should be canceled (for example, when the user tapped a `CANCEL` button in an HTML page). Provide ways for users to manually request autofill by calling `AutofillManager#requestAutofill(View, int, Rect)`. The `left` and `top` values set in `ViewStructure#setDimens(int, int, int, int, int, int)` must be relative to the next `ViewGroup#isImportantForAutofill()` predecessor view included in the structure. Views with virtual children support the Autofill Framework mainly by: Providing the metadata defining what the virtual children mean and how they can be autofilled. Implementing the methods that autofill the virtual children. This method is responsible for the former; `autofill(android.util.SparseArray)` is responsible for the latter.
`Unit`	`onProvideStructure(structure: ViewStructure!)` Called when assist structure is being retrieved from a view as part of `Activity.onProvideAssistData`.
`Unit`	`onProvideVirtualStructure(structure: ViewStructure!)` Called when assist structure is being retrieved from a view as part of `Activity.onProvideAssistData` to generate additional virtual structure under this view. The defaullt implementation uses `getAccessibilityNodeProvider()` to try to generate this from the view's virtual accessibility nodes, if any. You can override this for a more optimal implementation providing this data.
`Boolean`	`onSetAlpha(alpha: Int)` Invoked if there is a Transform that involves alpha. Subclass that can draw themselves with the specified alpha should return true, and then respect that alpha when their onDraw() is called. If this returns false then the view may be redirected to draw into an offscreen buffer to fulfill the request, which will look fine, but may be slower than if the subclass handles it internally. The default implementation returns false.
`Unit`	`onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int)` This is called during layout when the size of this view has changed. If you were just added to the view hierarchy, you're called with the old values of 0.
`Unit`	`onStartTemporaryDetach()` This is called when a container is going to temporarily detach a child, with `ViewGroup#detachViewFromParent(View)`. It will either be followed by `onFinishTemporaryDetach()` or `onDetachedFromWindow()` when the container is done.
`Unit`	`onVisibilityAggregated(isVisible: Boolean)` Called when the user-visibility of this View is potentially affected by a change to this view itself, an ancestor view or the window this view is attached to. If you override this method you must call through to the superclass implementation.
`Unit`	`onWindowSystemUiVisibilityChanged(visible: Int)` Override to find out when the window's requested system UI visibility has changed, that is the value returned by `getWindowSystemUiVisibility()`. This is different from the callbacks received through `setOnSystemUiVisibilityChangeListener(android.view.View.OnSystemUiVisibilityChangeListener)` in that this is only telling you about the local request of the window, not the actual values applied by the system.
`Unit`	`onWindowVisibilityChanged(visibility: Int)` Called when the window containing has change its visibility (between `GONE`, `INVISIBLE`, and `VISIBLE`). Note that this tells you whether or not your window is being made visible to the window manager; this does not tell you whether or not your window is obscured by other windows on the screen, even if it is itself visible.
`Boolean`	`overScrollBy(deltaX: Int, deltaY: Int, scrollX: Int, scrollY: Int, scrollRangeX: Int, scrollRangeY: Int, maxOverScrollX: Int, maxOverScrollY: Int, isTouchEvent: Boolean)` Scroll the view with standard behavior for scrolling beyond the normal content boundaries. Views that call this method should override `onOverScrolled(int,int,boolean,boolean)` to respond to the results of an over-scroll operation. Views can use this method to handle any touch or fling-based scrolling.
`Boolean`	`performAccessibilityAction(action: Int, arguments: Bundle!)` Performs the specified accessibility action on the view. For possible accessibility actions look at `AccessibilityNodeInfo`. If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#performAccessibilityAction(View, int, Bundle)` is responsible for handling this call. The default implementation will delegate `AccessibilityNodeInfo#ACTION_SCROLL_BACKWARD` and `AccessibilityNodeInfo#ACTION_SCROLL_FORWARD` to nested scrolling parents if `nested scrolling is enabled` on this view.
`Boolean`	`performClick()` Call this view's OnClickListener, if it is defined. Performs all normal actions associated with clicking: reporting accessibility event, playing a sound, etc.
`Boolean`	`performContextClick(x: Float, y: Float)` Call this view's OnContextClickListener, if it is defined.
`Boolean`	`performContextClick()` Call this view's OnContextClickListener, if it is defined.
`Boolean`	`performHapticFeedback(feedbackConstant: Int)` BZZZTT!!1! Provide haptic feedback to the user for this view. The framework will provide haptic feedback for some built in actions, such as long presses, but you may wish to provide feedback for your own widget. The feedback will only be performed if `isHapticFeedbackEnabled()` is true.
`Boolean`	`performHapticFeedback(feedbackConstant: Int, flags: Int)` BZZZTT!!1! Like `performHapticFeedback(int)`, with additional options.
`Boolean`	`performLongClick(x: Float, y: Float)` Calls this view's OnLongClickListener, if it is defined. Invokes the context menu if the OnLongClickListener did not consume the event, anchoring it to an (x,y) coordinate.
`Unit`	`playSoundEffect(soundConstant: Int)` Play a sound effect for this view. The framework will play sound effects for some built in actions, such as clicking, but you may wish to play these effects in your widget, for instance, for internal navigation. The sound effect will only be played if sound effects are enabled by the user, and `isSoundEffectsEnabled()` is true.
`Boolean`	`post(action: Runnable!)` Causes the Runnable to be added to the message queue. The runnable will be run on the user interface thread.
`Boolean`	`postDelayed(action: Runnable!, delayMillis: Long)` Causes the Runnable to be added to the message queue, to be run after the specified amount of time elapses. The runnable will be run on the user interface thread.
`Unit`	`postInvalidate()` Cause an invalidate to happen on a subsequent cycle through the event loop. Use this to invalidate the View from a non-UI thread. This method can be invoked from outside of the UI thread only when this View is attached to a window.
`Unit`	`postInvalidate(left: Int, top: Int, right: Int, bottom: Int)` Cause an invalidate of the specified area to happen on a subsequent cycle through the event loop. Use this to invalidate the View from a non-UI thread. This method can be invoked from outside of the UI thread only when this View is attached to a window.
`Unit`	`postInvalidateDelayed(delayMilliseconds: Long)` Cause an invalidate to happen on a subsequent cycle through the event loop. Waits for the specified amount of time. This method can be invoked from outside of the UI thread only when this View is attached to a window.
`Unit`	`postInvalidateDelayed(delayMilliseconds: Long, left: Int, top: Int, right: Int, bottom: Int)` Cause an invalidate of the specified area to happen on a subsequent cycle through the event loop. Waits for the specified amount of time. This method can be invoked from outside of the UI thread only when this View is attached to a window.
`Unit`	`postInvalidateOnAnimation()` Cause an invalidate to happen on the next animation time step, typically the next display frame. This method can be invoked from outside of the UI thread only when this View is attached to a window.
`Unit`	`postInvalidateOnAnimation(left: Int, top: Int, right: Int, bottom: Int)` Cause an invalidate of the specified area to happen on the next animation time step, typically the next display frame. This method can be invoked from outside of the UI thread only when this View is attached to a window.
`Unit`	`postOnAnimation(action: Runnable!)` Causes the Runnable to execute on the next animation time step. The runnable will be run on the user interface thread.
`Unit`	`postOnAnimationDelayed(action: Runnable!, delayMillis: Long)` Causes the Runnable to execute on the next animation time step, after the specified amount of time elapses. The runnable will be run on the user interface thread.
`Unit`	`refreshDrawableState()` Call this to force a view to update its drawable state. This will cause drawableStateChanged to be called on this view. Views that are interested in the new state should call getDrawableState.
`Unit`	`releasePointerCapture()` Releases the pointer capture. If the window does not have pointer capture, this call will do nothing.
`Boolean`	`removeCallbacks(action: Runnable!)` Removes the specified Runnable from the message queue.
`Unit`	`removeOnAttachStateChangeListener(listener: View.OnAttachStateChangeListener!)` Remove a listener for attach state changes. The listener will receive no further notification of window attach/detach events.
`Unit`	`removeOnLayoutChangeListener(listener: View.OnLayoutChangeListener!)` Remove a listener for layout changes.
`Unit`	`removeOnUnhandledKeyEventListener(listener: View.OnUnhandledKeyEventListener!)` Removes a listener which will receive unhandled `KeyEvent`s. This must be called on the UI thread.
`Unit`	`requestApplyInsets()` Ask that a new dispatch of `onApplyWindowInsets(android.view.WindowInsets)` be performed.
`Unit`	`requestFitSystemWindows()` Ask that a new dispatch of `fitSystemWindows(android.graphics.Rect)` be performed.
`Boolean`	`requestFocus()` Call this to try to give focus to a specific view or to one of its descendants. A view will not actually take focus if it is not focusable (`isFocusable` returns false), or if it can't be focused due to other conditions (not focusable in touch mode (`isFocusableInTouchMode`) while the device is in touch mode, not visible, not enabled, or has no size). See also `focusSearch(int)`, which is what you call to say that you have focus, and you want your parent to look for the next one. This is equivalent to calling `requestFocus(int,android.graphics.Rect)` with arguments `FOCUS_DOWN` and `null`.
`Boolean`	`requestFocus(direction: Int)` Call this to try to give focus to a specific view or to one of its descendants and give it a hint about what direction focus is heading. A view will not actually take focus if it is not focusable (`isFocusable` returns false), or if it is focusable and it is not focusable in touch mode (`isFocusableInTouchMode`) while the device is in touch mode. See also `focusSearch(int)`, which is what you call to say that you have focus, and you want your parent to look for the next one. This is equivalent to calling `requestFocus(int,android.graphics.Rect)` with `null` set for the previously focused rectangle.
`Boolean`	`requestFocus(direction: Int, previouslyFocusedRect: Rect!)` Call this to try to give focus to a specific view or to one of its descendants and give it hints about the direction and a specific rectangle that the focus is coming from. The rectangle can help give larger views a finer grained hint about where focus is coming from, and therefore, where to show selection, or forward focus change internally. A view will not actually take focus if it is not focusable (`isFocusable` returns false), or if it is focusable and it is not focusable in touch mode (`isFocusableInTouchMode`) while the device is in touch mode. A View will not take focus if it is not visible. A View will not take focus if one of its parents has `android.view.ViewGroup#getDescendantFocusability()` equal to `ViewGroup#FOCUS_BLOCK_DESCENDANTS`. See also `focusSearch(int)`, which is what you call to say that you have focus, and you want your parent to look for the next one. You may wish to override this method if your custom `View` has an internal `View` that it wishes to forward the request to.
`Boolean`	`requestFocusFromTouch()` Call this to try to give focus to a specific view or to one of its descendants. This is a special variant of `requestFocus()` that will allow views that are not focusable in touch mode to request focus when they are touched.
`Unit`	`requestLayout()` Call this when something has changed which has invalidated the layout of this view. This will schedule a layout pass of the view tree. This should not be called while the view hierarchy is currently in a layout pass (`isInLayout()`. If layout is happening, the request may be honored at the end of the current layout pass (and then layout will run again) or after the current frame is drawn and the next layout occurs. Subclasses which override this method should call the superclass method to handle possible request-during-layout errors correctly. If you override this method you must call through to the superclass implementation.
`Unit`	`requestPointerCapture()` Requests pointer capture mode. When the window has pointer capture, the mouse pointer icon will disappear and will not change its position. Further mouse will be dispatched with the source `InputDevice#SOURCE_MOUSE_RELATIVE`, and relative position changes will be available through `MotionEvent#getX` and `MotionEvent#getY`. Non-mouse events (touchscreens, or stylus) will not be affected. If the window already has pointer capture, this call does nothing. The capture may be released through `releasePointerCapture()`, or will be lost automatically when the window loses focus.
`Boolean`	`requestRectangleOnScreen(rectangle: Rect!)` Request that a rectangle of this view be visible on the screen, scrolling if necessary just enough. A View should call this if it maintains some notion of which part of its content is interesting. For example, a text editing view should call this when its cursor moves. The Rectangle passed into this method should be in the View's content coordinate space. It should not be affected by which part of the View is currently visible or its scroll position.
`Boolean`	`requestRectangleOnScreen(rectangle: Rect!, immediate: Boolean)` Request that a rectangle of this view be visible on the screen, scrolling if necessary just enough. A View should call this if it maintains some notion of which part of its content is interesting. For example, a text editing view should call this when its cursor moves. The Rectangle passed into this method should be in the View's content coordinate space. It should not be affected by which part of the View is currently visible or its scroll position. When `immediate` is set to true, scrolling will not be animated.
`Unit`	`requestUnbufferedDispatch(event: MotionEvent!)` Request unbuffered dispatch of the given stream of MotionEvents to this View. Until this View receives a corresponding `MotionEvent#ACTION_UP`, ask that the input system not batch `MotionEvent`s but instead deliver them as soon as they're available. This method should only be called for touch events. This api is not intended for most applications. Buffered dispatch provides many of benefits, and just requesting unbuffered dispatch on most MotionEvent streams will not improve your input latency. Side effects include: increased latency, jittery scrolls and inability to take advantage of system resampling. Talk to your input professional to see if `requestUnbufferedDispatch(android.view.MotionEvent)` is right for you.
`T`	`requireViewById(id: Int)` Finds the first descendant view with the given ID, the view itself if the ID matches `getId()`, or throws an IllegalArgumentException if the ID is invalid or there is no matching view in the hierarchy. Note: In most cases -- depending on compiler support -- the resulting view is automatically cast to the target class type. If the target class type is unconstrained, an explicit cast may be necessary.
`Unit`	`resetPivot()` Clears any pivot previously set by a call to `setPivotX(float)` or `setPivotY(float)`. After calling this `isPivotSet()` will be false and the pivot used for rotation will return to default of being centered on the view.
`Int`	`resolveSize(size: Int, measureSpec: Int)` Version of `resolveSizeAndState(int,int,int)` returning only the `MEASURED_SIZE_MASK` bits of the result.
`Int`	`resolveSizeAndState(size: Int, measureSpec: Int, childMeasuredState: Int)` Utility to reconcile a desired size and state, with constraints imposed by a MeasureSpec. Will take the desired size, unless a different size is imposed by the constraints. The returned value is a compound integer, with the resolved size in the `MEASURED_SIZE_MASK` bits and optionally the bit `MEASURED_STATE_TOO_SMALL` set if the resulting size is smaller than the size the view wants to be.
`Boolean`	`restoreDefaultFocus()` Gives focus to the default-focus view in the view hierarchy that has this view as a root. If the default-focus view cannot be found, falls back to calling `requestFocus(int)`.
`Unit`	`restoreHierarchyState(container: SparseArray<Parcelable!>!)` Restore this view hierarchy's frozen state from the given container.
`Unit`	`saveAttributeDataForStyleable(context: Context, styleable: IntArray, attrs: AttributeSet?, t: TypedArray, defStyleAttr: Int, defStyleRes: Int)` Stores debugging information about attributes. This should be called in a constructor by every custom `View` that uses a custom styleable. If the custom view does not call it, then the custom attributes used by this view will not be visible in layout inspection tools.
`Unit`	`saveHierarchyState(container: SparseArray<Parcelable!>!)` Store this view hierarchy's frozen state into the given container.
`Unit`	`scheduleDrawable(who: Drawable, what: Runnable, when: Long)` Schedules an action on a drawable to occur at a specified time.
`Unit`	`scrollBy(x: Int, y: Int)` Move the scrolled position of your view. This will cause a call to `onScrollChanged(int,int,int,int)` and the view will be invalidated.
`Unit`	`scrollTo(x: Int, y: Int)` Set the scrolled position of your view. This will cause a call to `onScrollChanged(int,int,int,int)` and the view will be invalidated.
`Unit`	`sendAccessibilityEvent(eventType: Int)` Sends an accessibility event of the given type. If accessibility is not enabled this method has no effect. The default implementation calls `onInitializeAccessibilityEvent(android.view.accessibility.AccessibilityEvent)` first to populate information about the event source (this View), then calls `dispatchPopulateAccessibilityEvent(android.view.accessibility.AccessibilityEvent)` to populate the text content of the event source including its descendants, and last calls `ViewParent#requestSendAccessibilityEvent(View, AccessibilityEvent)` on its parent to request sending of the event to interested parties. If an `AccessibilityDelegate` has been specified via calling `setAccessibilityDelegate(android.view.View.AccessibilityDelegate)` its `AccessibilityDelegate#sendAccessibilityEvent(View, int)` is responsible for handling this call.
`Unit`	`setAccessibilityDelegate(delegate: View.AccessibilityDelegate?)` Sets a delegate for implementing accessibility support via composition (as opposed to inheritance). For more details, see `AccessibilityDelegate`. Note: On platform versions prior to `API 23`, delegate methods on views in the `android.widget.` package are called before* host methods. This prevents certain properties such as class name from being modified by overriding `AccessibilityDelegate#onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfo)`, as any changes will be overwritten by the host class. Starting in `API 23`, delegate methods are called after host methods, which all properties to be modified without being overwritten by the host class.
`Unit`	`setAccessibilityHeading(isHeading: Boolean)` Set if view is a heading for a section of content for accessibility purposes.
`Unit`	`setAccessibilityLiveRegion(mode: Int)` Sets the live region mode for this view. This indicates to accessibility services whether they should automatically notify the user about changes to the view's content description or text, or to the content descriptions or text of the view's children (where applicable). For example, in a login screen with a TextView that displays an "incorrect password" notification, that view should be marked as a live region with mode `ACCESSIBILITY_LIVE_REGION_POLITE`. To disable change notifications for this view, use `ACCESSIBILITY_LIVE_REGION_NONE`. This is the default live region mode for most views. To indicate that the user should be notified of changes, use `ACCESSIBILITY_LIVE_REGION_POLITE`. If the view's changes should interrupt ongoing speech and notify the user immediately, use `ACCESSIBILITY_LIVE_REGION_ASSERTIVE`.
`Unit`	`setAccessibilityPaneTitle(accessibilityPaneTitle: CharSequence?)` Visually distinct portion of a window with window-like semantics are considered panes for accessibility purposes. One example is the content view of a fragment that is replaced. In order for accessibility services to understand a pane's window-like behavior, panes should have descriptive titles. Views with pane titles produce `AccessibilityEvent`s when they appear, disappear, or change title.
`Unit`	`setAccessibilityTraversalAfter(afterId: Int)` Sets the id of a view after which this one is visited in accessibility traversal. A screen-reader must visit the content of the other view before the content of this one. For example, if view B is set to be after view A, then a screen-reader will traverse the entire content of A before traversing the entire content of B, regardles of what traversal strategy it is using. Views that do not have specified before/after relationships are traversed in order determined by the screen-reader. Setting that this view is after a view that is not important for accessibility or if this view is not important for accessibility will have no effect as the screen-reader is not aware of unimportant views.
`Unit`	`setAccessibilityTraversalBefore(beforeId: Int)` Sets the id of a view before which this one is visited in accessibility traversal. A screen-reader must visit the content of this view before the content of the one it precedes. For example, if view B is set to be before view A, then a screen-reader will traverse the entire content of B before traversing the entire content of A, regardles of what traversal strategy it is using. Views that do not have specified before/after relationships are traversed in order determined by the screen-reader. Setting that this view is before a view that is not important for accessibility or if this view is not important for accessibility will have no effect as the screen-reader is not aware of unimportant views.
`Unit`	`setActivated(activated: Boolean)` Changes the activated state of this view. A view can be activated or not. Note that activation is not the same as selection. Selection is a transient property, representing the view (hierarchy) the user is currently interacting with. Activation is a longer-term state that the user can move views in and out of. For example, in a list view with single or multiple selection enabled, the views in the current selection set are activated. (Um, yeah, we are deeply sorry about the terminology here.) The activated state is propagated down to children of the view it is set on.
`Unit`	`setAlpha(alpha: Float)` Sets the opacity of the view to a value from 0 to 1, where 0 means the view is completely transparent and 1 means the view is completely opaque. Note: setting alpha to a translucent value (0 < alpha < 1) can have significant performance implications, especially for large views. It is best to use the alpha property sparingly and transiently, as in the case of fading animations. For a view with a frequently changing alpha, such as during a fading animation, it is strongly recommended for performance reasons to either override `hasOverlappingRendering()` to return `false` if appropriate, or setting a `layer type` on the view for the duration of the animation. On versions `android.os.Build.VERSION_CODES#M` and below, the default path for rendering an unlayered View with alpha could add multiple milliseconds of rendering cost, even for simple or small views. Starting with `android.os.Build.VERSION_CODES#M`, `LAYER_TYPE_HARDWARE` is automatically applied to the view at the rendering level. If this view overrides `onSetAlpha(int)` to return true, then this view is responsible for applying the opacity itself. On versions `android.os.Build.VERSION_CODES#LOLLIPOP_MR1` and below, note that if the view is backed by a `layer` and is associated with a `layer paint`, setting an alpha value less than 1.0 will supersede the alpha of the layer paint. Starting with `android.os.Build.VERSION_CODES#M`, setting a translucent alpha value will clip a View to its bounds, unless the View returns `false` from `hasOverlappingRendering`.
`Unit`	`setAnimation(animation: Animation!)` Sets the next animation to play for this view. If you want the animation to play immediately, use `startAnimation(android.view.animation.Animation)` instead. This method provides allows fine-grained control over the start time and invalidation, but you must make sure that 1) the animation has a start time set, and 2) the view's parent (which controls animations on its children) will be invalidated when the animation is supposed to start.
`Unit`	`setAnimationMatrix(matrix: Matrix?)` Changes the transformation matrix on the view. This is used in animation frameworks, such as `android.transition.Transition`. When the animation finishes, the matrix should be cleared by calling this method with `null` as the matrix parameter. Application developers should use transformation methods like `setRotation(float)`, `setScaleX(float)`, `setScaleX(float)`, `setTranslationX(float)`} and `setTranslationY(float)` (float)}} instead.
`Unit`	`setAutofillHints(vararg autofillHints: String!)` Sets the hints that help an `android.service.autofill.AutofillService` determine how to autofill the view with the user's data. Typically, there is only one way to autofill a view, but there could be more than one. For example, if the application accepts either an username or email address to identify an user. These hints are not validated by the Android System, but passed "as is" to the service. Hence, they can have any value, but it's recommended to use the `AUTOFILL_HINT_` constants such as: `AUTOFILL_HINT_USERNAME`, `AUTOFILL_HINT_PASSWORD`, `AUTOFILL_HINT_EMAIL_ADDRESS`, `AUTOFILL_HINT_NAME`, `AUTOFILL_HINT_PHONE`, `AUTOFILL_HINT_POSTAL_ADDRESS`, `AUTOFILL_HINT_POSTAL_CODE`, `AUTOFILL_HINT_CREDIT_CARD_NUMBER`, `AUTOFILL_HINT_CREDIT_CARD_SECURITY_CODE`, `AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DATE`, `AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_DAY`, `AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_MONTH` or `AUTOFILL_HINT_CREDIT_CARD_EXPIRATION_YEAR`.
`Unit`	`setAutofillId(id: AutofillId?)` Sets the unique, logical identifier of this view in the activity, for autofill purposes. The autofill id is created on demand, and this method should only be called when a view is reused after `dispatchProvideAutofillStructure(android.view.ViewStructure,int)` is called, as that method creates a snapshot of the view that is passed along to the autofill service. This method is typically used when view subtrees are recycled to represent different content* —in this case, the autofill id can be saved before the view content is swapped out, and restored later when it's swapped back in. For example: EditText reusableView = ...; ViewGroup parentView = ...; AutofillManager afm = ...; // Swap out the view and change its contents AutofillId oldId = reusableView.getAutofillId(); CharSequence oldText = reusableView.getText(); parentView.removeView(reusableView); AutofillId newId = afm.getNextAutofillId(); reusableView.setText("New I am"); reusableView.setAutofillId(newId); parentView.addView(reusableView); // Later, swap the old content back in parentView.removeView(reusableView); reusableView.setAutofillId(oldId); reusableView.setText(oldText); parentView.addView(reusableView);
`Unit`	`setBackground(background: Drawable!)` Set the background to a given Drawable, or remove the background. If the background has padding, this View's padding is set to the background's padding. However, when a background is removed, this View's padding isn't touched. If setting the padding is desired, please use `setPadding(int,int,int,int)`.
`Unit`	`setBackgroundColor(color: Int)` Sets the background color for this view.
`Unit`	`setBackgroundDrawable(background: Drawable!)`
`Unit`	`setBackgroundResource(resid: Int)` Set the background to a given resource. The resource should refer to a Drawable object or 0 to remove the background.
`Unit`	`setBackgroundTintBlendMode(blendMode: BlendMode?)` Specifies the blending mode used to apply the tint specified by `setBackgroundTintList(android.content.res.ColorStateList)`} to the background drawable. The default mode is `BlendMode#SRC_IN`.
`Unit`	`setBackgroundTintList(tint: ColorStateList?)` Applies a tint to the background drawable. Does not modify the current tint mode, which is `BlendMode#SRC_IN` by default. Subsequent calls to `setBackground(android.graphics.drawable.Drawable)` will automatically mutate the drawable and apply the specified tint and tint mode using `Drawable#setTintList(ColorStateList)`.
`Unit`	`setBackgroundTintMode(tintMode: PorterDuff.Mode?)` Specifies the blending mode used to apply the tint specified by `setBackgroundTintList(android.content.res.ColorStateList)`} to the background drawable. The default mode is `PorterDuff.Mode#SRC_IN`.
`Unit`	`setBottom(bottom: Int)` Sets the bottom position of this view relative to its parent. This method is meant to be called by the layout system and should not generally be called otherwise, because the property may be changed at any time by the layout.
`Unit`	`setCameraDistance(distance: Float)` Sets the distance along the Z axis (orthogonal to the X/Y plane on which views are drawn) from the camera to this view. The camera's distance affects 3D transformations, for instance rotations around the X and Y axis. If the rotationX or rotationY properties are changed and this view is large (more than half the size of the screen), it is recommended to always use a camera distance that's greater than the height (X axis rotation) or the width (Y axis rotation) of this view. The distance of the camera from the view plane can have an affect on the perspective distortion of the view when it is rotated around the x or y axis. For example, a large distance will result in a large viewing angle, and there will not be much perspective distortion of the view as it rotates. A short distance may cause much more perspective distortion upon rotation, and can also result in some drawing artifacts if the rotated view ends up partially behind the camera (which is why the recommendation is to use a distance at least as far as the size of the view, if the view is to be rotated.) The distance is expressed in "depth pixels." The default distance depends on the screen density. For instance, on a medium density display, the default distance is 1280. On a high density display, the default distance is 1920. If you want to specify a distance that leads to visually consistent results across various densities, use the following formula: float scale = context.getResources().getDisplayMetrics().density; view.setCameraDistance(distance * scale); The density scale factor of a high density display is 1.5, and 1920 = 1280 * 1.5.
`Unit`	`setClickable(clickable: Boolean)` Enables or disables click events for this view. When a view is clickable it will change its state to "pressed" on every click. Subclasses should set the view clickable to visually react to user's clicks.
`Unit`	`setClipBounds(clipBounds: Rect!)` Sets a rectangular area on this view to which the view will be clipped when it is drawn. Setting the value to null will remove the clip bounds and the view will draw normally, using its full bounds.
`Unit`	`setClipToOutline(clipToOutline: Boolean)` Sets whether the View's Outline should be used to clip the contents of the View. Only a single non-rectangular clip can be applied on a View at any time. Circular clips from a `ViewAnimationUtils#createCircularReveal(View, int, int, float, float)` animation take priority over Outline clipping, and child Outline clipping takes priority over Outline clipping done by a parent. Note that this flag will only be respected if the View's Outline returns true from `Outline#canClip()`.
`Unit`	`setContentCaptureSession(contentCaptureSession: ContentCaptureSession?)` Sets the (optional) `ContentCaptureSession` associated with this view. This method should be called when you need to associate a `ContentCaptureContext` to the content capture events associated with this view or its view hierarchy (if it's a `ViewGroup`). For example, if your activity is associated with a web domain, first you would need to set the context for the main DOM: ContentCaptureSession mainSession = rootView.getContentCaptureSession(); mainSession.setContentCaptureContext(ContentCaptureContext.forLocusId(Uri.parse(myUrl)); Then if the page had an `IFRAME`, you would create a new session for it: ContentCaptureSession iframeSession = mainSession.createContentCaptureSession( ContentCaptureContext.forLocusId(Uri.parse(iframeUrl))); iframeView.setContentCaptureSession(iframeSession);
`Unit`	`setContentDescription(contentDescription: CharSequence!)` Sets the `View`'s content description. A content description briefly describes the view and is primarily used for accessibility support to determine how a view should be presented to the user. In the case of a view with no textual representation, such as `android.widget.ImageButton`, a useful content description explains what the view does. For example, an image button with a phone icon that is used to place a call may use "Call" as its content description. An image of a floppy disk that is used to save a file may use "Save".
`Unit`	`setContextClickable(contextClickable: Boolean)` Enables or disables context clicking for this view. This event can launch the listener.
`Unit`	`setDefaultFocusHighlightEnabled(defaultFocusHighlightEnabled: Boolean)` Sets whether this View should use a default focus highlight when it gets focused but doesn't have `android.R.attr#state_focused` defined in its background.
`Unit`	`setDrawingCacheBackgroundColor(color: Int)` Setting a solid background color for the drawing cache's bitmaps will improve performance and memory usage. Note, though that this should only be used if this view will always be drawn on top of a solid color.
`Unit`	`setDrawingCacheEnabled(enabled: Boolean)` Enables or disables the drawing cache. When the drawing cache is enabled, the next call to `getDrawingCache()` or `buildDrawingCache()` will draw the view in a bitmap. Calling `draw(android.graphics.Canvas)` will not draw from the cache when the cache is enabled. To benefit from the cache, you must request the drawing cache by calling `getDrawingCache()` and draw it on screen if the returned bitmap is not null. Enabling the drawing cache is similar to `setting a layer` when hardware acceleration is turned off. When hardware acceleration is turned on, enabling the drawing cache has no effect on rendering because the system uses a different mechanism for acceleration which ignores the flag. If you want to use a Bitmap for the view, even when hardware acceleration is enabled, see `setLayerType(int,android.graphics.Paint)` for information on how to enable software and hardware layers. This API can be used to manually generate a bitmap copy of this view, by setting the flag to `true` and calling `getDrawingCache()`.
`Unit`	`setDrawingCacheQuality(quality: Int)` Set the drawing cache quality of this view. This value is used only when the drawing cache is enabled
`Unit`	`setDuplicateParentStateEnabled(enabled: Boolean)` Enables or disables the duplication of the parent's state into this view. When duplication is enabled, this view gets its drawable state from its parent rather than from its own internal properties. Note: in the current implementation, setting this property to true after the view was added to a ViewGroup might have no effect at all. This property should always be used from XML or set to true before adding this view to a ViewGroup. Note: if this view's parent addStateFromChildren property is enabled and this property is enabled, an exception will be thrown. Note: if the child view uses and updates additional states which are unknown to the parent, these states should not be affected by this method.
`Unit`	`setElevation(elevation: Float)` Sets the base elevation of this view, in pixels.
`Unit`	`setFadingEdgeLength(length: Int)` Set the size of the faded edge used to indicate that more content in this view is available. Will not change whether the fading edge is enabled; use `setVerticalFadingEdgeEnabled(boolean)` or `setHorizontalFadingEdgeEnabled(boolean)` to enable the fading edge for the vertical or horizontal fading edges.
`Unit`	`setFilterTouchesWhenObscured(enabled: Boolean)` Sets whether the framework should discard touches when the view's window is obscured by another visible window. Refer to the `View` security documentation for more details.
`Unit`	`setFitsSystemWindows(fitSystemWindows: Boolean)` Sets whether or not this view should account for system screen decorations such as the status bar and inset its content; that is, controlling whether the default implementation of `fitSystemWindows(android.graphics.Rect)` will be executed. See that method for more details. Note that if you are providing your own implementation of `fitSystemWindows(android.graphics.Rect)`, then there is no need to set this flag to true -- your implementation will be overriding the default implementation that checks this flag.
`Unit`	`setFocusable(focusable: Boolean)` Set whether this view can receive the focus. Setting this to false will also ensure that this view is not focusable in touch mode.
`Unit`	`setFocusable(focusable: Int)` Sets whether this view can receive focus. Setting this to `FOCUSABLE_AUTO` tells the framework to determine focusability automatically based on the view's interactivity. This is the default. Setting this to NOT_FOCUSABLE will ensure that this view is also not focusable in touch mode.
`Unit`	`setFocusableInTouchMode(focusableInTouchMode: Boolean)` Set whether this view can receive focus while in touch mode. Setting this to true will also ensure that this view is focusable.
`Unit`	`setFocusedByDefault(isFocusedByDefault: Boolean)` Sets whether this View should receive focus when the focus is restored for the view hierarchy containing this view. Focus gets restored for a view hierarchy when the root of the hierarchy gets added to a window or serves as a target of cluster navigation.
`Unit`	`setForceDarkAllowed(allow: Boolean)` Sets whether or not to allow force dark to apply to this view. Setting this to false will disable the auto-dark feature on everything this view draws, including any descendants. Setting this to true will allow this view to be automatically made dark, however a value of 'true' will not override any 'false' value in its parent chain nor will it prevent any 'false' in any of its children. The default behavior of force dark is also influenced by the Theme's `isLightTheme` attribute. If a theme is isLightTheme="false", then force dark is globally disabled for that theme.
`Unit`	`setForeground(foreground: Drawable!)` Supply a Drawable that is to be rendered on top of all of the content in the view.
`Unit`	`setForegroundGravity(gravity: Int)` Describes how the foreground is positioned. Defaults to START and TOP.
`Unit`	`setForegroundTintBlendMode(blendMode: BlendMode?)` Specifies the blending mode used to apply the tint specified by `setForegroundTintList(android.content.res.ColorStateList)`} to the background drawable. The default mode is `BlendMode#SRC_IN`.
`Unit`	`setForegroundTintList(tint: ColorStateList?)` Applies a tint to the foreground drawable. Does not modify the current tint mode, which is `PorterDuff.Mode#SRC_IN` by default. Subsequent calls to `setForeground(android.graphics.drawable.Drawable)` will automatically mutate the drawable and apply the specified tint and tint mode using `Drawable#setTintList(ColorStateList)`.
`Unit`	`setForegroundTintMode(tintMode: PorterDuff.Mode?)` Specifies the blending mode used to apply the tint specified by `setForegroundTintList(android.content.res.ColorStateList)`} to the background drawable. The default mode is `PorterDuff.Mode#SRC_IN`.
`Unit`	`setHapticFeedbackEnabled(hapticFeedbackEnabled: Boolean)` Set whether this view should have haptic feedback for events such as long presses. You may wish to disable haptic feedback if your view already controls its own haptic feedback.
`Unit`	`setHasTransientState(hasTransientState: Boolean)` Set whether this view is currently tracking transient state that the framework should attempt to preserve when possible. This flag is reference counted, so every call to setHasTransientState(true) should be paired with a later call to setHasTransientState(false). A view with transient state cannot be trivially rebound from an external data source, such as an adapter binding item views in a list. This may be because the view is performing an animation, tracking user selection of content, or similar.
`Unit`	`setHorizontalFadingEdgeEnabled(horizontalFadingEdgeEnabled: Boolean)` Define whether the horizontal edges should be faded when this view is scrolled horizontally.
`Unit`	`setHorizontalScrollBarEnabled(horizontalScrollBarEnabled: Boolean)` Define whether the horizontal scrollbar should be drawn or not. The scrollbar is not drawn by default.
`Unit`	`setHorizontalScrollbarThumbDrawable(drawable: Drawable?)` Defines the horizontal thumb drawable
`Unit`	`setHorizontalScrollbarTrackDrawable(drawable: Drawable?)` Defines the horizontal track drawable
`Unit`	`setHovered(hovered: Boolean)` Sets whether the view is currently hovered. Calling this method also changes the drawable state of the view. This enables the view to react to hover by using different drawable resources to change its appearance. The `onHoverChanged` method is called when the hovered state changes.
`Unit`	`setId(id: Int)` Sets the identifier for this view. The identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.
`Unit`	`setImportantForAccessibility(mode: Int)` Sets how to determine whether this view is important for accessibility which is if it fires accessibility events and if it is reported to accessibility services that query the screen.
`Unit`	`setImportantForAutofill(mode: Int)` Sets the mode for determining whether this view is considered important for autofill. The platform determines the importance for autofill automatically but you can use this method to customize the behavior. For example: When the view contents is irrelevant for autofill (for example, a text field used in a "Captcha" challenge), it should be `IMPORTANT_FOR_AUTOFILL_NO`. When both the view and its children are irrelevant for autofill (for example, the root view of an activity containing a spreadhseet editor), it should be `IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS`. When the view content is relevant for autofill but its children aren't (for example, a credit card expiration date represented by a custom view that overrides the proper autofill methods and has 2 children representing the month and year), it should be `IMPORTANT_FOR_AUTOFILL_YES_EXCLUDE_DESCENDANTS`. Note: Setting the mode as `IMPORTANT_FOR_AUTOFILL_NO` or `IMPORTANT_FOR_AUTOFILL_NO_EXCLUDE_DESCENDANTS` does not guarantee the view (and its children) will be always be considered not important; for example, when the user explicitly makes an autofill request, all views are considered important. See `isImportantForAutofill()` for more details about how the View's importance for autofill is used.
`Unit`	`setKeepScreenOn(keepScreenOn: Boolean)` Controls whether the screen should remain on, modifying the value of `KEEP_SCREEN_ON`.
`Unit`	`setKeyboardNavigationCluster(isCluster: Boolean)` Set whether this view is a root of a keyboard navigation cluster.
`Unit`	`setLabelFor(id: Int)` Sets the id of a view for which this view serves as a label for accessibility purposes.
`Unit`	`setLayerPaint(paint: Paint?)` Updates the `Paint` object used with the current layer (used only if the current layer type is not set to `LAYER_TYPE_NONE`). Changed properties of the Paint provided to `setLayerType(int,android.graphics.Paint)` will be used the next time the View is redrawn, but `setLayerPaint(android.graphics.Paint)` must be called to ensure that the view gets redrawn immediately. A layer is associated with an optional `android.graphics.Paint` instance that controls how the layer is composed on screen. The following properties of the paint are taken into account when composing the layer: `Translucency (alpha)` `Blending mode` `Color filter` If this view has an alpha value set to < 1.0 by calling `setAlpha(float)`, the alpha value of the layer's paint is superseded by this view's alpha value.
`Unit`	`setLayerType(layerType: Int, paint: Paint?)` Specifies the type of layer backing this view. The layer can be `LAYER_TYPE_NONE`, `LAYER_TYPE_SOFTWARE` or `LAYER_TYPE_HARDWARE`. A layer is associated with an optional `android.graphics.Paint` instance that controls how the layer is composed on screen. The following properties of the paint are taken into account when composing the layer: `Translucency (alpha)` `Blending mode` `Color filter` If this view has an alpha value set to < 1.0 by calling `setAlpha(float)`, the alpha value of the layer's paint is superseded by this view's alpha value. Refer to the documentation of `LAYER_TYPE_NONE`, `LAYER_TYPE_SOFTWARE` and `LAYER_TYPE_HARDWARE` for more information on when and how to use layers.
`Unit`	`setLayoutDirection(layoutDirection: Int)` Set the layout direction for this view. This will propagate a reset of layout direction resolution to the view's children and resolve layout direction for this view.
`Unit`	`setLayoutParams(params: ViewGroup.LayoutParams!)` Set the layout parameters associated with this view. These supply parameters to the parent of this view specifying how it should be arranged. There are many subclasses of ViewGroup.LayoutParams, and these correspond to the different subclasses of ViewGroup that are responsible for arranging their children.
`Unit`	`setLeft(left: Int)` Sets the left position of this view relative to its parent. This method is meant to be called by the layout system and should not generally be called otherwise, because the property may be changed at any time by the layout.
`Unit`	`setLeftTopRightBottom(left: Int, top: Int, right: Int, bottom: Int)` Assign a size and position to this view. This method is meant to be used in animations only as it applies this position and size for the view only temporary and it can be changed back at any time by the layout.
`Unit`	`setLongClickable(longClickable: Boolean)` Enables or disables long click events for this view. When a view is long clickable it reacts to the user holding down the button for a longer duration than a tap. This event can either launch the listener or a context menu.
`Unit`	`setMeasuredDimension(measuredWidth: Int, measuredHeight: Int)` This method must be called by `onMeasure(int,int)` to store the measured width and measured height. Failing to do so will trigger an exception at measurement time.
`Unit`	`setMinimumHeight(minHeight: Int)` Sets the minimum height of the view. It is not guaranteed the view will be able to achieve this minimum height (for example, if its parent layout constrains it with less available height).
`Unit`	`setMinimumWidth(minWidth: Int)` Sets the minimum width of the view. It is not guaranteed the view will be able to achieve this minimum width (for example, if its parent layout constrains it with less available width).
`Unit`	`setNestedScrollingEnabled(enabled: Boolean)` Enable or disable nested scrolling for this view. If this property is set to true the view will be permitted to initiate nested scrolling operations with a compatible parent view in the current hierarchy. If this view does not implement nested scrolling this will have no effect. Disabling nested scrolling while a nested scroll is in progress has the effect of `stopping` the nested scroll.
`Unit`	`setNextClusterForwardId(nextClusterForwardId: Int)` Sets the id of the view to use as the root of the next keyboard navigation cluster.
`Unit`	`setNextFocusDownId(nextFocusDownId: Int)` Sets the id of the view to use when the next focus is `FOCUS_DOWN`.
`Unit`	`setNextFocusForwardId(nextFocusForwardId: Int)` Sets the id of the view to use when the next focus is `FOCUS_FORWARD`.
`Unit`	`setNextFocusLeftId(nextFocusLeftId: Int)` Sets the id of the view to use when the next focus is `FOCUS_LEFT`.
`Unit`	`setNextFocusRightId(nextFocusRightId: Int)` Sets the id of the view to use when the next focus is `FOCUS_RIGHT`.
`Unit`	`setNextFocusUpId(nextFocusUpId: Int)` Sets the id of the view to use when the next focus is `FOCUS_UP`.
`Unit`	`setOnApplyWindowInsetsListener(listener: View.OnApplyWindowInsetsListener!)` Set an `OnApplyWindowInsetsListener` to take over the policy for applying window insets to this view. The listener's `OnApplyWindowInsetsListener#onApplyWindowInsets(View, WindowInsets)` method will be called instead of the view's `onApplyWindowInsets` method.
`Unit`	`setOnCapturedPointerListener(l: View.OnCapturedPointerListener!)` Set a listener to receive callbacks when the pointer capture state of a view changes.
`Unit`	`setOnClickListener(l: View.OnClickListener?)` Register a callback to be invoked when this view is clicked. If this view is not clickable, it becomes clickable.
`Unit`	`setOnContextClickListener(l: View.OnContextClickListener?)` Register a callback to be invoked when this view is context clicked. If the view is not context clickable, it becomes context clickable.
`Unit`	`setOnCreateContextMenuListener(l: View.OnCreateContextMenuListener!)` Register a callback to be invoked when the context menu for this view is being built. If this view is not long clickable, it becomes long clickable.
`Unit`	`setOnDragListener(l: View.OnDragListener!)` Register a drag event listener callback object for this View. The parameter is an implementation of `android.view.View.OnDragListener`. To send a drag event to a View, the system calls the `android.view.View.OnDragListener#onDrag(View,DragEvent)` method.
`Unit`	`setOnFocusChangeListener(l: View.OnFocusChangeListener!)` Register a callback to be invoked when focus of this view changed.
`Unit`	`setOnGenericMotionListener(l: View.OnGenericMotionListener!)` Register a callback to be invoked when a generic motion event is sent to this view.
`Unit`	`setOnHoverListener(l: View.OnHoverListener!)` Register a callback to be invoked when a hover event is sent to this view.
`Unit`	`setOnKeyListener(l: View.OnKeyListener!)` Register a callback to be invoked when a hardware key is pressed in this view. Key presses in software input methods will generally not trigger the methods of this listener.
`Unit`	`setOnLongClickListener(l: View.OnLongClickListener?)` Register a callback to be invoked when this view is clicked and held. If this view is not long clickable, it becomes long clickable.
`Unit`	`setOnScrollChangeListener(l: View.OnScrollChangeListener!)` Register a callback to be invoked when the scroll X or Y positions of this view change. Note: Some views handle scrolling independently from View and may have their own separate listeners for scroll-type events. For example, `ListView` allows clients to register an `AbsListView.OnScrollListener` to listen for changes in list scroll position.
`Unit`	`setOnSystemUiVisibilityChangeListener(l: View.OnSystemUiVisibilityChangeListener!)` Set a listener to receive callbacks when the visibility of the system bar changes.
`Unit`	`setOnTouchListener(l: View.OnTouchListener!)` Register a callback to be invoked when a touch event is sent to this view.
`Unit`	`setOutlineAmbientShadowColor(color: Int)` Sets the color of the ambient shadow that is drawn when the view has a positive Z or elevation value. By default the shadow color is black. Generally, this color will be opaque so the intensity of the shadow is consistent between different views with different colors. The opacity of the final ambient shadow is a function of the shadow caster height, the alpha channel of the outlineAmbientShadowColor (typically opaque), and the `android.R.attr#ambientShadowAlpha` theme attribute.
`Unit`	`setOutlineProvider(provider: ViewOutlineProvider!)` Sets the `ViewOutlineProvider` of the view, which generates the Outline that defines the shape of the shadow it casts, and enables outline clipping. The default ViewOutlineProvider, `ViewOutlineProvider#BACKGROUND`, queries the Outline from the View's background drawable, via `Drawable#getOutline(Outline)`. Changing the outline provider with this method allows this behavior to be overridden. If the ViewOutlineProvider is null, if querying it for an outline returns false, or if the produced Outline is `Outline#isEmpty()`, shadows will not be cast. Only outlines that return true from `Outline#canClip()` may be used for clipping.
`Unit`	`setOutlineSpotShadowColor(color: Int)` Sets the color of the spot shadow that is drawn when the view has a positive Z or elevation value. By default the shadow color is black. Generally, this color will be opaque so the intensity of the shadow is consistent between different views with different colors. The opacity of the final spot shadow is a function of the shadow caster height, the alpha channel of the outlineSpotShadowColor (typically opaque), and the `android.R.attr#spotShadowAlpha` theme attribute.
`Unit`	`setOverScrollMode(overScrollMode: Int)` Set the over-scroll mode for this view. Valid over-scroll modes are `OVER_SCROLL_ALWAYS`, `OVER_SCROLL_IF_CONTENT_SCROLLS` (allow over-scrolling only if the view content is larger than the container), or `OVER_SCROLL_NEVER`. Setting the over-scroll mode of a view will have an effect only if the view is capable of scrolling.
`Unit`	`setPivotX(pivotX: Float)` Sets the x location of the point around which the view is `rotated` and `scaled`. By default, the pivot point is centered on the object. Setting this property disables this behavior and causes the view to use only the explicitly set pivotX and pivotY values.
`Unit`	`setPivotY(pivotY: Float)` Sets the y location of the point around which the view is `rotated` and `scaled`. By default, the pivot point is centered on the object. Setting this property disables this behavior and causes the view to use only the explicitly set pivotX and pivotY values.
`Unit`	`setPointerIcon(pointerIcon: PointerIcon!)` Set the pointer icon for the current view. Passing `null` will restore the pointer icon to its default value.
`Unit`	`setPressed(pressed: Boolean)` Sets the pressed state for this view.
`Unit`	`setRevealOnFocusHint(revealOnFocus: Boolean)` Sets this view's preference for reveal behavior when it gains focus. When set to true, this is a signal to ancestor views in the hierarchy that this view would prefer to be brought fully into view when it gains focus. For example, a text field that a user is meant to type into. Other views such as scrolling containers may prefer to opt-out of this behavior. The default value for views is true, though subclasses may change this based on their preferred behavior.
`Unit`	`setRight(right: Int)` Sets the right position of this view relative to its parent. This method is meant to be called by the layout system and should not generally be called otherwise, because the property may be changed at any time by the layout.
`Unit`	`setRotation(rotation: Float)` Sets the degrees that the view is rotated around the pivot point. Increasing values result in clockwise rotation.
`Unit`	`setRotationX(rotationX: Float)` Sets the degrees that the view is rotated around the horizontal axis through the pivot point. Increasing values result in clockwise rotation from the viewpoint of looking down the x axis. When rotating large views, it is recommended to adjust the camera distance accordingly. Refer to `setCameraDistance(float)` for more information.
`Unit`	`setRotationY(rotationY: Float)` Sets the degrees that the view is rotated around the vertical axis through the pivot point. Increasing values result in counter-clockwise rotation from the viewpoint of looking down the y axis. When rotating large views, it is recommended to adjust the camera distance accordingly. Refer to `setCameraDistance(float)` for more information.
`Unit`	`setSaveEnabled(enabled: Boolean)` Controls whether the saving of this view's state is enabled (that is, whether its `onSaveInstanceState` method will be called). Note that even if freezing is enabled, the view still must have an id assigned to it (via `setId(int)`) for its state to be saved. This flag can only disable the saving of this view; any child views may still have their state saved.
`Unit`	`setSaveFromParentEnabled(enabled: Boolean)` Controls whether the entire hierarchy under this view will save its state when a state saving traversal occurs from its parent. The default is true; if false, these views will not be saved unless `saveHierarchyState(android.util.SparseArray)` is called directly on this view.
`Unit`	`setScaleX(scaleX: Float)` Sets the amount that the view is scaled in x around the pivot point, as a proportion of the view's unscaled width. A value of 1 means that no scaling is applied.
`Unit`	`setScaleY(scaleY: Float)` Sets the amount that the view is scaled in Y around the pivot point, as a proportion of the view's unscaled width. A value of 1 means that no scaling is applied.
`Unit`	`setScreenReaderFocusable(screenReaderFocusable: Boolean)` Sets whether this View should be a focusable element for screen readers and include non-focusable Views from its subtree when providing feedback. Note: this is similar to using `android:focusable`, but does not impact input focus behavior.
`Unit`	`setScrollBarDefaultDelayBeforeFade(scrollBarDefaultDelayBeforeFade: Int)` Define the delay before scrollbars fade.
`Unit`	`setScrollBarFadeDuration(scrollBarFadeDuration: Int)` Define the scrollbar fade duration.
`Unit`	`setScrollBarSize(scrollBarSize: Int)` Define the scrollbar size.
`Unit`	`setScrollBarStyle(style: Int)` Specify the style of the scrollbars. The scrollbars can be overlaid or inset. When inset, they add to the padding of the view. And the scrollbars can be drawn inside the padding area or on the edge of the view. For example, if a view has a background drawable and you want to draw the scrollbars inside the padding specified by the drawable, you can use SCROLLBARS_INSIDE_OVERLAY or SCROLLBARS_INSIDE_INSET. If you want them to appear at the edge of the view, ignoring the padding, then you can use SCROLLBARS_OUTSIDE_OVERLAY or SCROLLBARS_OUTSIDE_INSET.
`Unit`	`setScrollContainer(isScrollContainer: Boolean)` Change whether this view is one of the set of scrollable containers in its window. This will be used to determine whether the window can resize or must pan when a soft input area is open -- scrollable containers allow the window to use resize mode since the container will appropriately shrink.
`Unit`	`setScrollIndicators(indicators: Int)` Sets the state of all scroll indicators. See `setScrollIndicators(int,int)` for usage information.
`Unit`	`setScrollIndicators(indicators: Int, mask: Int)` Sets the state of the scroll indicators specified by the mask. To change all scroll indicators at once, see `setScrollIndicators(int)`. When a scroll indicator is enabled, it will be displayed if the view can scroll in the direction of the indicator. Multiple indicator types may be enabled or disabled by passing the logical OR of the desired types. If multiple types are specified, they will all be set to the same enabled state. For example, to enable the top scroll indicatorExample: setScrollIndicators indicators the indicator direction, or the logical OR of multiple indicator directions. One or more of: <ul> <li>{ #SCROLL_INDICATOR_TOP}</li> <li>{ #SCROLL_INDICATOR_BOTTOM}</li> <li>{ #SCROLL_INDICATOR_LEFT}</li> <li>{ #SCROLL_INDICATOR_RIGHT}</li> <li>{ #SCROLL_INDICATOR_START}</li> <li>{ #SCROLL_INDICATOR_END}</li> </ul> #setScrollIndicators(int) #getScrollIndicators() ref android.R.styleable#View_scrollIndicators indicators Value is either <code>0</code> or a combination of { android.view.View#SCROLL_INDICATOR_TOP}, { android.view.View#SCROLL_INDICATOR_BOTTOM}, { android.view.View#SCROLL_INDICATOR_LEFT}, { android.view.View#SCROLL_INDICATOR_RIGHT}, { android.view.View#SCROLL_INDICATOR_START}, and { android.view.View#SCROLL_INDICATOR_END} mask Value is either <code>0</code> or a combination of { android.view.View#SCROLL_INDICATOR_TOP}, { android.view.View#SCROLL_INDICATOR_BOTTOM}, { android.view.View#SCROLL_INDICATOR_LEFT}, { android.view.View#SCROLL_INDICATOR_RIGHT}, { android.view.View#SCROLL_INDICATOR_START}, and { android.view.View#SCROLL_INDICATOR_END} 23
`Unit`	`setScrollX(value: Int)` Set the horizontal scrolled position of your view. This will cause a call to `onScrollChanged(int,int,int,int)` and the view will be invalidated.
`Unit`	`setScrollY(value: Int)` Set the vertical scrolled position of your view. This will cause a call to `onScrollChanged(int,int,int,int)` and the view will be invalidated.
`Unit`	`setScrollbarFadingEnabled(fadeScrollbars: Boolean)` Define whether scrollbars will fade when the view is not scrolling.
`Unit`	`setSoundEffectsEnabled(soundEffectsEnabled: Boolean)` Set whether this view should have sound effects enabled for events such as clicking and touching. You may wish to disable sound effects for a view if you already play sounds, for instance, a dial key that plays dtmf tones.
`Unit`	`setStateListAnimator(stateListAnimator: StateListAnimator!)` Attaches the provided StateListAnimator to this View. Any previously attached StateListAnimator will be detached.
`Unit`	`setSystemGestureExclusionRects(rects: MutableList<Rect!>)` Sets a list of areas within this view's post-layout coordinate space where the system should not intercept touch or other pointing device gestures. This method should be called by `onLayout(boolean,int,int,int,int)` or `onDraw(android.graphics.Canvas)`. Use this to tell the system which specific sub-areas of a view need to receive gesture input in order to function correctly in the presence of global system gestures that may conflict. For example, if the system wishes to capture swipe-in-from-screen-edge gestures to provide system-level navigation functionality, a view such as a navigation drawer container can mark the left (or starting) edge of itself as requiring gesture capture priority using this API. The system may then choose to relax its own gesture recognition to allow the app to consume the user's gesture. It is not necessary for an app to register exclusion rects for broadly spanning regions such as the entirety of a `ScrollView` or for simple press and release click targets such as `Button`. Mark an exclusion rect when interacting with a view requires a precision touch gesture in a small area in either the X or Y dimension, such as an edge swipe or dragging a `SeekBar` thumb. Do not modify the provided list after this method is called. Note: the system will put a limit of `200dp` on the vertical extent of the exclusions it takes into account. The limit does not apply while the navigation bar is `stickily` hidden, nor to the `input method` and `Intent#CATEGORY_HOME`.
`Unit`	`setSystemUiVisibility(visibility: Int)` Request that the visibility of the status bar or other screen/window decorations be changed. This method is used to put the over device UI into temporary modes where the user's attention is focused more on the application content, by dimming or hiding surrounding system affordances. This is typically used in conjunction with `Window#FEATURE_ACTION_BAR_OVERLAY`, allowing the applications content to be placed behind the action bar (and with these flags other system affordances) so that smooth transitions between hiding and showing them can be done. Two representative examples of the use of system UI visibility is implementing a content browsing application (like a magazine reader) and a video playing application. The first code shows a typical implementation of a View in a content browsing application. In this implementation, the application goes into a content-oriented mode by hiding the status bar and action bar, and putting the navigation elements into lights out mode. The user can then interact with content while in this mode. Such an application should provide an easy way for the user to toggle out of the mode (such as to check information in the status bar or access notifications). In the implementation here, this is done simply by tapping on the content. public static class Content extends ScrollView implements View.OnSystemUiVisibilityChangeListener, View.OnClickListener { TextView mText; TextView mTitleView; SeekBar mSeekView; boolean mNavVisible; int mBaseSystemUiVisibility = SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN \| SYSTEM_UI_FLAG_LAYOUT_STABLE; int mLastSystemUiVis; Runnable mNavHider = new Runnable() { @Override public void run() { setNavVisibility(false); } }; public Content(Context context, AttributeSet attrs) { super(context, attrs); mText = new TextView(context); mText.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16); mText.setText(context.getString(R.string.alert_dialog_two_buttons2ultra_msg)); mText.setClickable(false); mText.setOnClickListener(this); mText.setTextIsSelectable(true); addView(mText, new ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); setOnSystemUiVisibilityChangeListener(this); } public void init(TextView title, SeekBar seek) { // This called by the containing activity to supply the surrounding // state of the content browser that it will interact with. mTitleView = title; mSeekView = seek; setNavVisibility(true); } @Override public void onSystemUiVisibilityChange(int visibility) { // Detect when we go out of low-profile mode, to also go out // of full screen. We only do this when the low profile mode // is changing from its last state, and turning off. int diff = mLastSystemUiVis ^ visibility; mLastSystemUiVis = visibility; if ((diff&SYSTEM_UI_FLAG_LOW_PROFILE) != 0 && (visibility&SYSTEM_UI_FLAG_LOW_PROFILE) == 0) { setNavVisibility(true); } } @Override protected void onWindowVisibilityChanged(int visibility) { super.onWindowVisibilityChanged(visibility); // When we become visible, we show our navigation elements briefly // before hiding them. setNavVisibility(true); getHandler().postDelayed(mNavHider, 2000); } @Override protected void onScrollChanged(int l, int t, int oldl, int oldt) { super.onScrollChanged(l, t, oldl, oldt); // When the user scrolls, we hide navigation elements. setNavVisibility(false); } @Override public void onClick(View v) { // When the user clicks, we toggle the visibility of navigation elements. int curVis = getSystemUiVisibility(); setNavVisibility((curVis&SYSTEM_UI_FLAG_LOW_PROFILE) != 0); } void setBaseSystemUiVisibility(int visibility) { mBaseSystemUiVisibility = visibility; } void setNavVisibility(boolean visible) { int newVis = mBaseSystemUiVisibility; if (!visible) { newVis \|= SYSTEM_UI_FLAG_LOW_PROFILE \| SYSTEM_UI_FLAG_FULLSCREEN; } final boolean changed = newVis == getSystemUiVisibility(); // Unschedule any pending event to hide navigation if we are // changing the visibility, or making the UI visible. if (changed \|\| visible) { Handler h = getHandler(); if (h != null) { h.removeCallbacks(mNavHider); } } // Set the new desired visibility. setSystemUiVisibility(newVis); mTitleView.setVisibility(visible ? VISIBLE : INVISIBLE); mSeekView.setVisibility(visible ? VISIBLE : INVISIBLE); } } This second code sample shows a typical implementation of a View in a video playing application. In this situation, while the video is playing the application would like to go into a complete full-screen mode, to use as much of the display as possible for the video. When in this state the user can not interact with the application; the system intercepts touching on the screen to pop the UI out of full screen mode. See `fitSystemWindows(android.graphics.Rect)` for a sample layout that goes with this code. public static class Content extends ImageView implements View.OnSystemUiVisibilityChangeListener, View.OnClickListener, ActionBar.OnMenuVisibilityListener { Activity mActivity; TextView mTitleView; Button mPlayButton; SeekBar mSeekView; boolean mAddedMenuListener; boolean mMenusOpen; boolean mPaused; boolean mNavVisible; int mLastSystemUiVis; Runnable mNavHider = new Runnable() { @Override public void run() { setNavVisibility(false); } }; public Content(Context context, AttributeSet attrs) { super(context, attrs); setOnSystemUiVisibilityChangeListener(this); setOnClickListener(this); } public void init(Activity activity, TextView title, Button playButton, SeekBar seek) { // This called by the containing activity to supply the surrounding // state of the video player that it will interact with. mActivity = activity; mTitleView = title; mPlayButton = playButton; mSeekView = seek; mPlayButton.setOnClickListener(this); setPlayPaused(true); } @Override protected void onAttachedToWindow() { super.onAttachedToWindow(); if (mActivity != null) { mAddedMenuListener = true; mActivity.getActionBar().addOnMenuVisibilityListener(this); } } @Override protected void onDetachedFromWindow() { super.onDetachedFromWindow(); if (mAddedMenuListener) { mActivity.getActionBar().removeOnMenuVisibilityListener(this); } } @Override public void onSystemUiVisibilityChange(int visibility) { // Detect when we go out of nav-hidden mode, to clear our state // back to having the full UI chrome up. Only do this when // the state is changing and nav is no longer hidden. int diff = mLastSystemUiVis ^ visibility; mLastSystemUiVis = visibility; if ((diff&SYSTEM_UI_FLAG_HIDE_NAVIGATION) != 0 && (visibility&SYSTEM_UI_FLAG_HIDE_NAVIGATION) == 0) { setNavVisibility(true); } } @Override protected void onWindowVisibilityChanged(int visibility) { super.onWindowVisibilityChanged(visibility); // When we become visible or invisible, play is paused. setPlayPaused(true); } @Override public void onClick(View v) { if (v == mPlayButton) { // Clicking on the play/pause button toggles its state. setPlayPaused(!mPaused); } else { // Clicking elsewhere makes the navigation visible. setNavVisibility(true); } } @Override public void onMenuVisibilityChanged(boolean isVisible) { mMenusOpen = isVisible; setNavVisibility(true); } void setPlayPaused(boolean paused) { mPaused = paused; mPlayButton.setText(paused ? R.string.play : R.string.pause); setKeepScreenOn(!paused); setNavVisibility(true); } void setNavVisibility(boolean visible) { int newVis = SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN \| SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION \| SYSTEM_UI_FLAG_LAYOUT_STABLE; if (!visible) { newVis \|= SYSTEM_UI_FLAG_LOW_PROFILE \| SYSTEM_UI_FLAG_FULLSCREEN \| SYSTEM_UI_FLAG_HIDE_NAVIGATION; } // If we are now visible, schedule a timer for us to go invisible. if (visible) { Handler h = getHandler(); if (h != null) { h.removeCallbacks(mNavHider); if (!mMenusOpen && !mPaused) { // If the menus are open or play is paused, we will not auto-hide. h.postDelayed(mNavHider, 3000); } } } // Set the new desired visibility. setSystemUiVisibility(newVis); mTitleView.setVisibility(visible ? VISIBLE : INVISIBLE); mPlayButton.setVisibility(visible ? VISIBLE : INVISIBLE); mSeekView.setVisibility(visible ? VISIBLE : INVISIBLE); } }
`Unit`	`setTag(tag: Any!)` Sets the tag associated with this view. A tag can be used to mark a view in its hierarchy and does not have to be unique within the hierarchy. Tags can also be used to store data within a view without resorting to another data structure.
`Unit`	`setTag(key: Int, tag: Any!)` Sets a tag associated with this view and a key. A tag can be used to mark a view in its hierarchy and does not have to be unique within the hierarchy. Tags can also be used to store data within a view without resorting to another data structure. The specified key should be an id declared in the resources of the application to ensure it is unique (see the ID resource type). Keys identified as belonging to the Android framework or not associated with any package will cause an `IllegalArgumentException` to be thrown.
`Unit`	`setTextAlignment(textAlignment: Int)` Set the text alignment.
`Unit`	`setTextDirection(textDirection: Int)` Set the text direction.
`Unit`	`setTooltipText(tooltipText: CharSequence?)` Sets the tooltip text which will be displayed in a small popup next to the view. The tooltip will be displayed: On long click, unless it is handled otherwise (by OnLongClickListener or a context menu). On hover, after a brief delay since the pointer has stopped moving Note: Do not override this method, as it will have no effect on the text displayed in the tooltip.
`Unit`	`setTop(top: Int)` Sets the top position of this view relative to its parent. This method is meant to be called by the layout system and should not generally be called otherwise, because the property may be changed at any time by the layout.
`Unit`	`setTouchDelegate(delegate: TouchDelegate!)` Sets the TouchDelegate for this View.
`Unit`	`setTransitionAlpha(alpha: Float)` This property is intended only for use by the Fade transition, which animates it to produce a visual translucency that does not side-effect (or get affected by) the real alpha property. This value is composited with the other alpha value (and the AlphaAnimation value, when that is present) to produce a final visual translucency result, which is what is passed into the DisplayList.
`Unit`	`setTransitionName(transitionName: String!)` Sets the name of the View to be used to identify Views in Transitions. Names should be unique in the View hierarchy.
`Unit`	`setTransitionVisibility(visibility: Int)` Changes the visibility of this View without triggering any other changes. This should only be used by animation frameworks, such as `android.transition.Transition`, where visibility changes should not adjust focus or trigger a new layout. Application developers should use `setVisibility` instead to ensure that the hierarchy is correctly updated. Only call this method when a temporary visibility must be applied during an animation and the original visibility value is guaranteed to be reset after the animation completes. Use `setVisibility` in all other cases.
`Unit`	`setTranslationX(translationX: Float)` Sets the horizontal location of this view relative to its `left` position. This effectively positions the object post-layout, in addition to wherever the object's layout placed it.
`Unit`	`setTranslationY(translationY: Float)` Sets the vertical location of this view relative to its `top` position. This effectively positions the object post-layout, in addition to wherever the object's layout placed it.
`Unit`	`setTranslationZ(translationZ: Float)` Sets the depth location of this view relative to its `elevation`.
`Unit`	`setVerticalFadingEdgeEnabled(verticalFadingEdgeEnabled: Boolean)` Define whether the vertical edges should be faded when this view is scrolled vertically.
`Unit`	`setVerticalScrollBarEnabled(verticalScrollBarEnabled: Boolean)` Define whether the vertical scrollbar should be drawn or not. The scrollbar is not drawn by default.
`Unit`	`setVerticalScrollbarPosition(position: Int)` Set the position of the vertical scroll bar. Should be one of `SCROLLBAR_POSITION_DEFAULT`, `SCROLLBAR_POSITION_LEFT` or `SCROLLBAR_POSITION_RIGHT`.
`Unit`	`setVerticalScrollbarThumbDrawable(drawable: Drawable?)` Defines the vertical scrollbar thumb drawable
`Unit`	`setVerticalScrollbarTrackDrawable(drawable: Drawable?)` Defines the vertical scrollbar track drawable
`Unit`	`setVisibility(visibility: Int)` Set the visibility state of this view.
`Unit`	`setWillNotCacheDrawing(willNotCacheDrawing: Boolean)` When a View's drawing cache is enabled, drawing is redirected to an offscreen bitmap. Some views, like an ImageView, must be able to bypass this mechanism if they already draw a single bitmap, to avoid unnecessary usage of the memory.
`Unit`	`setWillNotDraw(willNotDraw: Boolean)` If this view doesn't do any drawing on its own, set this flag to allow further optimizations. By default, this flag is not set on View, but could be set on some View subclasses such as ViewGroup. Typically, if you override `onDraw(android.graphics.Canvas)` you should clear this flag.
`Unit`	`setX(x: Float)` Sets the visual x position of this view, in pixels. This is equivalent to setting the `translationX` property to be the difference between the x value passed in and the current `left` property.
`Unit`	`setY(y: Float)` Sets the visual y position of this view, in pixels. This is equivalent to setting the `translationY` property to be the difference between the y value passed in and the current `top` property.
`Unit`	`setZ(z: Float)` Sets the visual z position of this view, in pixels. This is equivalent to setting the `translationZ` property to be the difference between the z value passed in and the current `elevation` property.
`ActionMode!`	`startActionMode(callback: ActionMode.Callback!)` Start an action mode with the default type `ActionMode#TYPE_PRIMARY`.
`ActionMode!`	`startActionMode(callback: ActionMode.Callback!, type: Int)` Start an action mode with the given type.
`Unit`	`startAnimation(animation: Animation!)` Start the specified animation now.
`Boolean`	`startDrag(data: ClipData!, shadowBuilder: View.DragShadowBuilder!, myLocalState: Any!, flags: Int)`
`Boolean`	`startDragAndDrop(data: ClipData!, shadowBuilder: View.DragShadowBuilder!, myLocalState: Any!, flags: Int)` Starts a drag and drop operation. When your application calls this method, it passes a `android.view.View.DragShadowBuilder` object to the system. The system calls this object's `DragShadowBuilder#onProvideShadowMetrics(Point, Point)` to get metrics for the drag shadow, and then calls the object's `DragShadowBuilder#onDrawShadow(Canvas)` to draw the drag shadow itself. Once the system has the drag shadow, it begins the drag and drop operation by sending drag events to all the View objects in your application that are currently visible. It does this either by calling the View object's drag listener (an implementation of `onDrag()` or by calling the View object's `onDragEvent()` method. Both are passed a `android.view.DragEvent` object that has a `android.view.DragEvent#getAction()` value of `android.view.DragEvent#ACTION_DRAG_STARTED`. Your application can invoke `startDragAndDrop()` on any attached View object. The View object does not need to be the one used in `android.view.View.DragShadowBuilder`, nor does it need to be related to the View the user selected for dragging.
`Boolean`	`startNestedScroll(axes: Int)` Begin a nestable scroll operation along the given axes. A view starting a nested scroll promises to abide by the following contract: The view will call startNestedScroll upon initiating a scroll operation. In the case of a touch scroll this corresponds to the initial `MotionEvent#ACTION_DOWN`. In the case of touch scrolling the nested scroll will be terminated automatically in the same manner as `ViewParent#requestDisallowInterceptTouchEvent(boolean)`. In the event of programmatic scrolling the caller must explicitly call `stopNestedScroll()` to indicate the end of the nested scroll. If `startNestedScroll` returns true, a cooperative parent was found. If it returns false the caller may ignore the rest of this contract until the next scroll. Calling startNestedScroll while a nested scroll is already in progress will return true. At each incremental step of the scroll the caller should invoke `dispatchNestedPreScroll` once it has calculated the requested scrolling delta. If it returns true the nested scrolling parent at least partially consumed the scroll and the caller should adjust the amount it scrolls by. After applying the remainder of the scroll delta the caller should invoke `dispatchNestedScroll`, passing both the delta consumed and the delta unconsumed. A nested scrolling parent may treat these values differently. See `ViewParent#onNestedScroll(View, int, int, int, int)`.
`Unit`	`stopNestedScroll()` Stop a nested scroll in progress. Calling this method when a nested scroll is not currently in progress is harmless.
`String`	`toString()`
`Unit`	`transformMatrixToGlobal(matrix: Matrix)` Modifies the input matrix such that it maps view-local coordinates to on-screen coordinates.
`Unit`	`transformMatrixToLocal(matrix: Matrix)` Modifies the input matrix such that it maps on-screen coordinates to view-local coordinates.
`Unit`	`unscheduleDrawable(who: Drawable, what: Runnable)` Cancels a scheduled action on a drawable.
`Unit`	`unscheduleDrawable(who: Drawable!)` Unschedule any events associated with the given Drawable. This can be used when selecting a new Drawable into a view, so that the previous one is completely unscheduled.
`Unit`	`updateDragShadow(shadowBuilder: View.DragShadowBuilder!)` Updates the drag shadow for the ongoing drag and drop operation.
`Boolean`	`willNotCacheDrawing()` Returns whether or not this View can cache its drawing or not.
`Boolean`	`willNotDraw()` Returns whether or not this View draws on its own.

android:imeOptions

Additional features you can enable in an IME associated with an editor to improve the integration with your application. The constants here correspond to those defined by android.view.inputmethod.EditorInfo#imeOptions.

Must be one or more (separated by '|') of the following constant values.

Constant	Value	Description
actionDone	6	The action key performs a "done" operation, closing the soft input method. Corresponds to `android.view.inputmethod.EditorInfo#IME_ACTION_DONE`.
actionGo	2	The action key performs a "go" operation to take the user to the target of the text they typed. Typically used, for example, when entering a URL. Corresponds to `android.view.inputmethod.EditorInfo#IME_ACTION_GO`.
actionNext	5	The action key performs a "next" operation, taking the user to the next field that will accept text. Corresponds to `android.view.inputmethod.EditorInfo#IME_ACTION_NEXT`.
actionNone	1	This editor has no action associated with it. Corresponds to `android.view.inputmethod.EditorInfo#IME_ACTION_NONE`.
actionPrevious	7	The action key performs a "previous" operation, taking the user to the previous field that will accept text. Corresponds to `android.view.inputmethod.EditorInfo#IME_ACTION_PREVIOUS`.
actionSearch	3	The action key performs a "search" operation, taking the user to the results of searching for the text the have typed (in whatever context is appropriate). Corresponds to `android.view.inputmethod.EditorInfo#IME_ACTION_SEARCH`.
actionSend	4	The action key performs a "send" operation, delivering the text to its target. This is typically used when composing a message. Corresponds to `android.view.inputmethod.EditorInfo#IME_ACTION_SEND`.
actionUnspecified	0	There is no specific action associated with this editor, let the editor come up with its own if it can. Corresponds to `android.view.inputmethod.EditorInfo#IME_NULL`.
flagForceAscii	80000000	Used to request that the IME should be capable of inputting ASCII characters. The intention of this flag is to ensure that the user can type Roman alphabet characters in a `android.widget.TextView` used for, typically, account ID or password input. It is expected that IMEs normally are able to input ASCII even without being told so (such IMEs already respect this flag in a sense), but there could be some cases they aren't when, for instance, only non-ASCII input languages like Arabic, Greek, Hebrew, Russian are enabled in the IME. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it. However, it is strongly recommended for IME authors to respect this flag especially when their IME could end up with a state that has only non-ASCII input languages enabled. Corresponds to `android.view.inputmethod.EditorInfo#IME_FLAG_FORCE_ASCII`.
flagNavigateNext	8000000	Used to specify that there is something interesting that a forward navigation can focus on. This is like using actionNext, except allows the IME to be multiline (with an enter key) as well as provide forward navigation. Note that some IMEs may not be able to do this, especially when running on a small screen where there is little space. In that case it does not need to present a UI for this option. Like actionNext, if the user selects the IME's facility to forward navigate, this will show up in the application at `InputConnection.performEditorAction(int)`. Corresponds to `android.view.inputmethod.EditorInfo#IME_FLAG_NAVIGATE_NEXT`.
flagNavigatePrevious	4000000	Like flagNavigateNext, but specifies there is something interesting that a backward navigation can focus on. If the user selects the IME's facility to backward navigate, this will show up in the application as an actionPrevious at `InputConnection.performEditorAction(int)`. Corresponds to `android.view.inputmethod.EditorInfo#IME_FLAG_NAVIGATE_PREVIOUS`.
flagNoAccessoryAction	20000000	Used in conjunction with a custom action, this indicates that the action should not be available as an accessory button when the input method is full-screen. Note that by setting this flag, there can be cases where the action is simply never available to the user. Setting this generally means that you think showing text being edited is more important than the action you have supplied. Corresponds to `android.view.inputmethod.EditorInfo#IME_FLAG_NO_ACCESSORY_ACTION`.
flagNoEnterAction	40000000	Used in conjunction with a custom action, this indicates that the action should not be available in-line as a replacement for the "enter" key. Typically this is because the action has such a significant impact or is not recoverable enough that accidentally hitting it should be avoided, such as sending a message. Note that `android.widget.TextView` will automatically set this flag for you on multi-line text views. Corresponds to `android.view.inputmethod.EditorInfo#IME_FLAG_NO_ENTER_ACTION`.
flagNoExtractUi	10000000	Used to specify that the IME does not need to show its extracted text UI. For input methods that may be fullscreen, often when in landscape mode, this allows them to be smaller and let part of the application be shown behind. Though there will likely be limited access to the application available from the user, it can make the experience of a (mostly) fullscreen IME less jarring. Note that when this flag is specified the IME may not be set up to be able to display text, so it should only be used in situations where this is not needed. Corresponds to `android.view.inputmethod.EditorInfo#IME_FLAG_NO_EXTRACT_UI`.
flagNoFullscreen	2000000	Used to request that the IME never go into fullscreen mode. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it. Corresponds to `android.view.inputmethod.EditorInfo#IME_FLAG_NO_FULLSCREEN`.
flagNoPersonalizedLearning	1000000	Used to request that the IME should not update any personalized data such as typing history and personalized language model based on what the user typed on this text editing object. Typical use cases are: When the application is in a special mode, where user's activities are expected to be not recorded in the application's history. Some web browsers and chat applications may have this kind of modes. When storing typing history does not make much sense. Specifying this flag in typing games may help to avoid typing history from being filled up with words that the user is less likely to type in their daily life. Another example is that when the application already knows that the expected input is not a valid word (e.g. a promotion code that is not a valid word in any natural language). Applications need to be aware that the flag is not a guarantee, and some IMEs may not respect it.
normal	0	There are no special semantics associated with this editor.
