NestedScrollingChild2

public interface NestedScrollingChild2
implements NestedScrollingChild

Known Indirect Subclasses BaseGridView,HorizontalGridView,NestedScrollView,RecyclerView,VerticalGridView,WearableRecyclerView BaseGridView An abstract base class for vertically and horizontally scrolling lists.  HorizontalGridView A ViewGroup that shows items in a horizontal scrolling list.  NestedScrollView NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android.  RecyclerView A flexible view for providing a limited window into a large data set.  VerticalGridView A ViewGroup that shows items in a vertically scrolling list.  WearableRecyclerView Wearable specific implementation of the RecyclerView enabling setCircularScrollingGestureEnabled(boolean) circular scrolling} and semi-circular layouts.

This interface should be implemented by View subclasses that wish to support dispatching nested scrolling operations to a cooperating parent ViewGroup.

Classes implementing this interface should create a final instance of a NestedScrollingChildHelper as a field and delegate any View methods to the NestedScrollingChildHelper methods of the same signature.

Views invoking nested scrolling functionality should always do so from the relevant ViewCompat, ViewGroupCompat or ViewParentCompat compatibility shim static methods. This ensures interoperability with nested scrolling views on all versions of Android.
