RecyclerView.SimpleOnItemTouchListener

Class Overview

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.

Public Methods
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.
void	onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) Called when a child of RecyclerView does not want RecyclerView and its ancestors to intercept touch events with `onInterceptTouchEvent(MotionEvent)`.
void	onTouchEvent(RecyclerView rv, MotionEvent e) Process a touch event as part of a gesture that was claimed by returning true from a previous call to `onInterceptTouchEvent(RecyclerView, MotionEvent)`.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

From interface android.support.v7.widget.RecyclerView.OnItemTouchListener

Public Methods

public 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

e	MotionEvent describing the touch event. All coordinates are in the RecyclerView's coordinate system.

Returns

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.

public void onRequestDisallowInterceptTouchEvent (boolean disallowIntercept)

Called when a child of RecyclerView does not want RecyclerView and its ancestors to intercept touch events with onInterceptTouchEvent(MotionEvent).

Parameters

disallowIntercept	True if the child does not want the parent to intercept touch events.

public void onTouchEvent (RecyclerView rv, MotionEvent e)

Process a touch event as part of a gesture that was claimed by returning true from a previous call to onInterceptTouchEvent(RecyclerView, MotionEvent).

Parameters

e	MotionEvent describing the touch event. All coordinates are in the RecyclerView's coordinate system.
