RecyclerView.ChildDrawingOrderCallback
| android.support.v7.widget.RecyclerView.ChildDrawingOrderCallback |
A callback interface that can be used to alter the drawing order of RecyclerView children.
It works using the getChildDrawingOrder(int, int) 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.
