ChildDrawingOrderCallback unspecified API

```
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 casethat applies to that method also applies to this callback. For example, changing the drawingorder of two views will not have any effect if their elevation values are different sinceelevation overrides the result of this callback.
