public class GridLayoutManager
extends LinearLayoutManager

java.lang.Object
↳	android.support.v7.widget.RecyclerView.LayoutManager
	↳	android.support.v7.widget.LinearLayoutManager
		↳	android.support.v7.widget.GridLayoutManager

A RecyclerView.LayoutManager implementations that lays out items in a grid.

By default, each item occupies 1 span. You can change it by providing a custom GridLayoutManager.SpanSizeLookup instance via setSpanSizeLookup(SpanSizeLookup).

Summary

Nested classes
`class`	`GridLayoutManager.DefaultSpanSizeLookup` Default implementation for `GridLayoutManager.SpanSizeLookup`.
`class`	`GridLayoutManager.LayoutParams` LayoutParams used by GridLayoutManager.
`class`	`GridLayoutManager.SpanSizeLookup` A helper class to provide the number of spans each item occupies.

Public constructors
`GridLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes)` Constructor used when layout manager is set in XML by RecyclerView attribute "layoutManager".
`GridLayoutManager(Context context, int spanCount)` Creates a vertical GridLayoutManager
`GridLayoutManager(Context context, int spanCount, int orientation, boolean reverseLayout)`

Public methods
`boolean`	`checkLayoutParams(RecyclerView.LayoutParams lp)` Determines the validity of the supplied LayoutParams object.
`RecyclerView.LayoutParams`	`generateDefaultLayoutParams()` Create a default `LayoutParams` object for a child of the RecyclerView.
`RecyclerView.LayoutParams`	`generateLayoutParams(Context c, AttributeSet attrs)` Create a LayoutParams object suitable for this LayoutManager from an inflated layout resource.
`RecyclerView.LayoutParams`	`generateLayoutParams(ViewGroup.LayoutParams lp)` Create a LayoutParams object suitable for this LayoutManager, copying relevant values from the supplied LayoutParams object if possible.
`int`	`getColumnCountForAccessibility(RecyclerView.Recycler recycler, RecyclerView.State state)` Returns the number of columns for accessibility.
`int`	`getRowCountForAccessibility(RecyclerView.Recycler recycler, RecyclerView.State state)` Returns the number of rows for accessibility.
`int`	`getSpanCount()` Returns the number of spans laid out by this grid.
`GridLayoutManager.SpanSizeLookup`	`getSpanSizeLookup()` Returns the current `GridLayoutManager.SpanSizeLookup` used by the GridLayoutManager.
`View`	`onFocusSearchFailed(View focused, int focusDirection, RecyclerView.Recycler recycler, RecyclerView.State state)` Called when searching for a focusable view in the given direction has failed for the current content of the RecyclerView.
`void`	`onInitializeAccessibilityNodeInfoForItem(RecyclerView.Recycler recycler, RecyclerView.State state, View host, AccessibilityNodeInfoCompat info)` Called by the AccessibilityDelegate when the accessibility information for a specific item should be populated.
`void`	`onItemsAdded(RecyclerView recyclerView, int positionStart, int itemCount)` Called when items have been added to the adapter.
`void`	`onItemsChanged(RecyclerView recyclerView)` Called in response to a call to `notifyDataSetChanged()` or `swapAdapter(Adapter, boolean)` ()} and signals that the the entire data set has changed.
`void`	`onItemsMoved(RecyclerView recyclerView, int from, int to, int itemCount)` Called when an item is moved withing the adapter.
`void`	`onItemsRemoved(RecyclerView recyclerView, int positionStart, int itemCount)` Called when items have been removed from the adapter.
`void`	`onItemsUpdated(RecyclerView recyclerView, int positionStart, int itemCount, Object payload)` Called when items have been changed in the adapter and with optional payload.
`void`	`onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state)` Lay out all relevant child views from the given adapter.
`void`	`onLayoutCompleted(RecyclerView.State state)` Called after a full layout calculation is finished.
`int`	`scrollHorizontallyBy(int dx, RecyclerView.Recycler recycler, RecyclerView.State state)` Scroll horizontally by dx pixels in screen coordinates and return the distance traveled.
`int`	`scrollVerticallyBy(int dy, RecyclerView.Recycler recycler, RecyclerView.State state)` Scroll vertically by dy pixels in screen coordinates and return the distance traveled.
`void`	`setMeasuredDimension(Rect childrenBounds, int wSpec, int hSpec)` Sets the measured dimensions from the given bounding box of the children and the measurement specs that were passed into `onMeasure(int, int)`.
`void`	`setSpanCount(int spanCount)` Sets the number of spans to be laid out.
`void`	`setSpanSizeLookup(GridLayoutManager.SpanSizeLookup spanSizeLookup)` Sets the source to get the number of spans occupied by each item in the adapter.
`void`	`setStackFromEnd(boolean stackFromEnd)` stackFromEnd is not supported by GridLayoutManager.
`boolean`	`supportsPredictiveItemAnimations()` Returns whether this LayoutManager supports "predictive item animations".
