HandwritingDelegateConfiguration

Kotlin |Java

public class HandwritingDelegateConfiguration
extends Object

java.lang.Object
↳	android.view.HandwritingDelegateConfiguration

Configuration for a view to act as a handwriting initiation delegate. This allows handwriting mode for a delegator editor view to be initiated by stylus movement on the delegate view.

If a stylus MotionEvent occurs within the delegate view's bounds, the callback returned by getInitiationCallback() will be called. The callback implementation is expected to show and focus the delegator editor view. If a view with identifier matching getDelegatorViewId() creates an input connection while the same stylus MotionEvent sequence is ongoing, handwriting mode will be initiated for that view.

A common use case is a custom view which looks like a text editor but does not actually support text editing itself, and clicking on the custom view causes an EditText to be shown. To support handwriting initiation in this case, View#setHandwritingDelegateConfiguration can be called on the custom view to configure it as a delegate, and set the EditText as the delegator by passing the EditText's identifier as the delegatorViewId. The initiationCallback implementation is typically the same as the click listener implementation which shows the EditText.

Summary

Public constructors
`HandwritingDelegateConfiguration(int delegatorViewId, Runnable initiationCallback)` Constructs a HandwritingDelegateConfiguration instance.

Public methods
`int`	`getDelegatorViewId()` Returns the identifier of the delegator editor view for which handwriting mode should be initiated.
`Runnable`	`getInitiationCallback()` Returns the callback which should be called when a stylus `MotionEvent` occurs within the delegate view's bounds.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public constructors

HandwritingDelegateConfiguration

Added in Android UpsideDownCake

public HandwritingDelegateConfiguration (int delegatorViewId, 
                Runnable initiationCallback)

Constructs a HandwritingDelegateConfiguration instance.

Parameters
`delegatorViewId`	`int`: identifier of the delegator editor view for which handwriting mode should be initiated
`initiationCallback`	`Runnable`: callback called when a stylus `MotionEvent` occurs within this view's bounds. This will be called from the UI thread. This value cannot be `null`.

Public methods

getDelegatorViewId

Added in Android UpsideDownCake

public int getDelegatorViewId ()

Returns the identifier of the delegator editor view for which handwriting mode should be initiated.

Returns
`int`

getInitiationCallback

Added in Android UpsideDownCake

public Runnable getInitiationCallback ()

Returns the callback which should be called when a stylus MotionEvent occurs within the delegate view's bounds. The callback should only be called from the UI thread.

Returns
`Runnable`	This value cannot be `null`.
