↳ | android.support.v7.widget.RecyclerView.SimpleOnItemTouchListener |
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.

RecyclerView.SimpleOnItemTouchListener ()
boolean onInterceptTouchEvent (RecyclerView rv, 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.
Parameters | |

rv |
RecyclerView
|
e |
MotionEvent :
MotionEvent describing the touch event. All coordinates are in
the RecyclerView's coordinate system. |
Returns | |
---|---|
boolean |
true if this OnItemTouchListener wishes to begin intercepting touch events, false to continue with the current behavior and continue observing future events in the gesture. |
void onRequestDisallowInterceptTouchEvent (boolean disallowIntercept)
Called when a child of RecyclerView does not want RecyclerView and its ancestors to
intercept touch events with
