OnItemTouchListener unspecified API

```
public interface RecyclerView.OnItemTouchListener

                    
```
An OnItemTouchListener allows the application to intercept touch events in progress at theview hierarchy level of the RecyclerView before those touch events are considered forRecyclerView's own scrolling behavior.
This can be useful for applications that wish to implement various forms of gesturalmanipulation of item views within the RecyclerView. OnItemTouchListeners may intercepta touch interaction already in progress even if the RecyclerView is already handling thatgesture stream itself for the purposes of scrolling.

    The onInterceptTouchEvent methods of each attached OnItemTouchListener will be runin the order in which each listener was added, before any other touch processingby the RecyclerView itself or child views occurs.
    
    Parameters:
    
    e - MotionEvent describing the touch event.
  - onTouchEvent
```
 abstract void onTouchEvent(@NonNull() RecyclerView rv, @NonNull() MotionEvent e)
```
    Process a touch event as part of a gesture that was claimed by returning true froma previous call to onInterceptTouchEvent.
    
    Parameters:
    
    e - MotionEvent describing the touch event.
  - onRequestDisallowInterceptTouchEvent
```
 abstract void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept)
```
    Called when a child of RecyclerView does not want RecyclerView and its ancestors tointercept touch events with onInterceptTouchEvent.
    
    Parameters:
    
    disallowIntercept - True if the child does not want the parent tointercept touch events.
