RecyclerView.SimpleOnItemTouchListener
public class RecyclerView.SimpleOnItemTouchListener implements RecyclerView.OnItemTouchListener
An implementation of RecyclerView.OnItemTouchListener that has empty method bodies and default return values.
You may prefer to extend this class if you don't need to override all methods. Another benefit of using this class is future compatibility. As the interface may change, we'll always provide a default implementation on this class so that your code won't break when you update to a new version of the support library.

onInterceptTouchEvent
public boolean onInterceptTouchEvent(@NonNull RecyclerView rv, @NonNull MotionEvent e)
Silently observe and/or take over touch events sent to the RecyclerView before they are handled by either the RecyclerView itself or its child views.
The onInterceptTouchEvent methods of each attached OnItemTouchListener will be run in the order in which each listener was added, before any other touch processing by the RecyclerView itself or child views occurs.
onRequestDisallowInterceptTouchEvent
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept)
Called when a child of RecyclerView does not want RecyclerView and its ancestors to intercept touch events with ViewGroup#onInterceptTouchEvent(MotionEvent).
onTouchEvent
public void onTouchEvent(@NonNull RecyclerView rv, @NonNull MotionEvent e)
