RecyclerView.ChildDrawingOrderCallback
public interface RecyclerView.ChildDrawingOrderCallback
A callback interface that can be used to alter the drawing order of RecyclerView children.
It works using the getChildDrawingOrder method, so any case that applies to that method also applies to this callback. For example, changing the drawing order of two views will not have any effect if their elevation values are different since elevation overrides the result of this callback.
