Known direct subclasses

HorizontalGridView, VerticalGridView

HorizontalGridView	A `ViewGroup` that shows items in a horizontal scrolling list.
VerticalGridView	A `ViewGroup` that shows items in a vertically scrolling list.

An abstract base class for vertically and horizontally scrolling lists. The items come from the RecyclerView.Adapter associated with this view. Do not directly use this class, use VerticalGridView and HorizontalGridView. The class is not intended to be subclassed other than VerticalGridView and HorizontalGridView.

Value indicates that percent is not used.

Constant Value: -1.0

SAVE_ALL_CHILD

public static final int SAVE_ALL_CHILD

Save on screen views plus save off screen child views without any limitation. This might cause out of memory, only use it when you are dealing with limited data.

Constant Value: 3 (0x00000003)

SAVE_LIMITED_CHILD

public static final int SAVE_LIMITED_CHILD

Save on screen views plus save off screen child views states up to getSaveChildrenLimitNumber().

Constant Value: 2 (0x00000002)

SAVE_NO_CHILD

public static final int SAVE_NO_CHILD

Dont save states of any child views.

Constant Value: 0 (0x00000000)

SAVE_ON_SCREEN_CHILD

public static final int SAVE_ON_SCREEN_CHILD

Only save on screen child views, the states are lost when they become off screen.

Constant Value: 1 (0x00000001)

WINDOW_ALIGN_BOTH_EDGE

public static final int WINDOW_ALIGN_BOTH_EDGE

The first item and last item are aligned with the two edges of the viewport. When navigating in the middle of list, the focus maintains a key line location.

The key line location is calculated by "windowAlignOffset" and "windowAlignOffsetPercent"; if neither of these two is defined, the default value is 1/2 of the size.

Constant Value: 3 (0x00000003)

WINDOW_ALIGN_HIGH_EDGE

public static final int WINDOW_ALIGN_HIGH_EDGE

The last item is aligned with the high edge of the viewport when navigating to the end of list. When navigating away from the end, the focus item is aligned to a key line location.

For HorizontalGridView, high edge refers to getWidth() - getPaddingRight() when RTL is false or getPaddingLeft() when RTL is true. For VerticalGridView, high edge refers to getHeight() - getPaddingBottom().

The key line location is calculated by "windowAlignOffset" and "windowAlignOffsetPercent"; if neither of these two is defined, the default value is 1/2 of the size.

Note if there are very few items between high edge and key line, use setWindowAlignmentPreferKeyLineOverHighEdge(boolean) to control whether you prefer to align the items to key line or high edge. Default is preferring key line.

Constant Value: 2 (0x00000002)

WINDOW_ALIGN_LOW_EDGE

public static final int WINDOW_ALIGN_LOW_EDGE

The first item is aligned with the low edge of the viewport. When navigating away from the first item, the focus item is aligned to a key line location.

For HorizontalGridView, low edge refers to getPaddingLeft() when RTL is false or getWidth() - getPaddingRight() when RTL is true. For VerticalGridView, low edge refers to getPaddingTop().

The key line location is calculated by "windowAlignOffset" and "windowAlignOffsetPercent"; if neither of these two is defined, the default value is 1/2 of the size.

Note if there are very few items between low edge and key line, use setWindowAlignmentPreferKeyLineOverLowEdge(boolean) to control whether you prefer to align the items to key line or low edge. Default is preferring low edge.

Constant Value: 1 (0x00000001)

WINDOW_ALIGN_NO_EDGE

public static final int WINDOW_ALIGN_NO_EDGE

The focused item always stays in a key line location.

The key line location is calculated by "windowAlignOffset" and "windowAlignOffsetPercent"; if neither of these two is defined, the default value is 1/2 of the size.

Constant Value: 0 (0x00000000)

WINDOW_ALIGN_OFFSET_PERCENT_DISABLED

public static final float WINDOW_ALIGN_OFFSET_PERCENT_DISABLED

Value indicates that percent is not used.

Constant Value: -1.0

public void setHorizontalSpacing (int spacing)

Sets the horizontal spacing in pixels between two child items.

Parameters
`spacing`	`int`: Horizontal spacing in pixels between two child items.

setInitialPrefetchItemCount

public void setInitialPrefetchItemCount (int itemCount)

Sets the number of items to prefetch in RecyclerView.LayoutManager.collectInitialPrefetchPositions(int, RecyclerView.LayoutManager.LayoutPrefetchRegistry), which defines how many inner items should be prefetched when this GridView is nested inside another RecyclerView.

Set this value to the number of items this inner GridView will display when it is first scrolled into the viewport. RecyclerView will attempt to prefetch that number of items so they are ready, avoiding jank as the inner GridView is scrolled into the viewport.

For example, take a VerticalGridView of scrolling HorizontalGridViews. The rows always have 6 items visible in them (or 7 if not aligned). Passing 6 to this method for each inner GridView will enable RecyclerView's prefetching feature to do create/bind work for 6 views within a row early, before it is scrolled on screen, instead of just the default 4.

Calling this method does nothing unless the LayoutManager is in a RecyclerView nested in another RecyclerView.

Note: Setting this value to be larger than the number of views that will be visible in this view can incur unnecessary bind work, and an increase to the number of Views created and in active use.

`itemCount`	`int`: Number of items to prefetch

Sets the offset percent for item alignment in addition to getItemAlignmentOffset(). Item alignment settings are ignored for the child if ItemAlignmentFacet is provided by RecyclerView.ViewHolder or FacetProviderAdapter.

Parameters
`offsetPercent`	`float`: Percentage to offset. E.g., 40 means 40% of the width from the low edge. Use `ITEM_ALIGN_OFFSET_PERCENT_DISABLED` to disable.
