OnItemTouchListener

interface OnItemTouchListener(source)

An OnItemTouchListener allows the application to intercept touch events in progress at the view hierarchy level of the RecyclerView before those touch events are considered for RecyclerView's own scrolling behavior.

This can be useful for applications that wish to implement various forms of gestural manipulation of item views within the RecyclerView. OnItemTouchListeners may intercept a touch interaction already in progress even if the RecyclerView is already handling that gesture stream itself for the purposes of scrolling.
