Known direct subclasses

HorizontalGridView, VerticalGridView

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