Public methods
`void`	`assertNotInLayoutOrScroll(String message)` Checks if RecyclerView is in the middle of a layout or scroll and throws an `IllegalStateException` if it is.
`boolean`	`canScrollHorizontally()` Query if horizontal scrolling is currently supported.
`boolean`	`canScrollVertically()` Query if vertical scrolling is currently supported.
`void`	`collectAdjacentPrefetchPositions(int dx, int dy, RecyclerView.State state, RecyclerView.LayoutManager.LayoutPrefetchRegistry layoutPrefetchRegistry)` Gather all positions from the LayoutManager to be prefetched, given specified momentum.
`void`	`collectInitialPrefetchPositions(int adapterItemCount, RecyclerView.LayoutManager.LayoutPrefetchRegistry layoutPrefetchRegistry)` Gather all positions from the LayoutManager to be prefetched in preperation for its RecyclerView to come on screen, due to the movement of another, containing RecyclerView.
`int`	`computeHorizontalScrollExtent(RecyclerView.State state)` Override this method if you want to support scroll bars.
`int`	`computeHorizontalScrollOffset(RecyclerView.State state)` Override this method if you want to support scroll bars.
`int`	`computeHorizontalScrollRange(RecyclerView.State state)` Override this method if you want to support scroll bars.
`PointF`	`computeScrollVectorForPosition(int targetPosition)` Should calculate the vector that points to the direction where the target position can be found.
`int`	`computeVerticalScrollExtent(RecyclerView.State state)` Override this method if you want to support scroll bars.
`int`	`computeVerticalScrollOffset(RecyclerView.State state)` Override this method if you want to support scroll bars.
`int`	`computeVerticalScrollRange(RecyclerView.State state)` Override this method if you want to support scroll bars.
`int`	`findFirstCompletelyVisibleItemPosition()` Returns the adapter position of the first fully visible view.
`int`	`findFirstVisibleItemPosition()` Returns the adapter position of the first visible view.
`int`	`findLastCompletelyVisibleItemPosition()` Returns the adapter position of the last fully visible view.
`int`	`findLastVisibleItemPosition()` Returns the adapter position of the last visible view.
`View`	`findViewByPosition(int position)` Finds the view which represents the given adapter position.
`RecyclerView.LayoutParams`	`generateDefaultLayoutParams()` Create a default `LayoutParams` object for a child of the RecyclerView.
`int`	`getInitialPrefetchItemCount()` Gets the number of items to prefetch in `collectInitialPrefetchPositions(int, LayoutPrefetchRegistry)`, which defines how many inner items should be prefetched when this LayoutManager's RecyclerView is nested inside another RecyclerView.
`int`	`getOrientation()` Returns the current orientation of the layout.
`boolean`	`getRecycleChildrenOnDetach()` Returns whether LayoutManager will recycle its children when it is detached from RecyclerView.
`boolean`	`getReverseLayout()` Returns if views are laid out from the opposite direction of the layout.
`boolean`	`getStackFromEnd()`
`boolean`	`isAutoMeasureEnabled()` Returns whether the measuring pass of layout should use the AutoMeasure mechanism of `RecyclerView` or if it should be done by the LayoutManager's implementation of `onMeasure(Recycler, State, int, int)`.
`boolean`	`isSmoothScrollbarEnabled()` Returns the current state of the smooth scrollbar feature.
`void`	`onDetachedFromWindow(RecyclerView view, RecyclerView.Recycler recycler)` Called when this LayoutManager is detached from its parent RecyclerView or when its parent RecyclerView is detached from its window.
`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`	`onInitializeAccessibilityEvent(AccessibilityEvent event)`
`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.
`void`	`onRestoreInstanceState(Parcelable state)`
`Parcelable`	`onSaveInstanceState()` Called when the LayoutManager should save its state.
`int`	`scrollHorizontallyBy(int dx, RecyclerView.Recycler recycler, RecyclerView.State state)` Scroll horizontally by dx pixels in screen coordinates and return the distance traveled.
`void`	`scrollToPosition(int position)` Scroll the RecyclerView to make the position visible.
`void`	`scrollToPositionWithOffset(int position, int offset)` Scroll to the specified adapter position with the given offset from resolved layout start.
`int`	`scrollVerticallyBy(int dy, RecyclerView.Recycler recycler, RecyclerView.State state)` Scroll vertically by dy pixels in screen coordinates and return the distance traveled.
`void`	`setInitialPrefetchItemCount(int itemCount)` Sets the number of items to prefetch in `collectInitialPrefetchPositions(int, LayoutPrefetchRegistry)`, which defines how many inner items should be prefetched when this LayoutManager's RecyclerView is nested inside another RecyclerView.
`void`	`setOrientation(int orientation)` Sets the orientation of the layout.
`void`	`setRecycleChildrenOnDetach(boolean recycleChildrenOnDetach)` Set whether LayoutManager will recycle its children when it is detached from RecyclerView.
`void`	`setReverseLayout(boolean reverseLayout)` Used to reverse item traversal and layout order.
`void`	`setSmoothScrollbarEnabled(boolean enabled)` When smooth scrollbar is enabled, the position and size of the scrollbar thumb is computed based on the number of visible pixels in the visible items.
`void`	`setStackFromEnd(boolean stackFromEnd)` Compatibility support for `setStackFromBottom(boolean)`
`void`	`smoothScrollToPosition(RecyclerView recyclerView, RecyclerView.State state, int position)` Smooth scroll to the specified adapter position.
