GestureDetector.SimpleOnGestureListener

public static class GestureDetector.SimpleOnGestureListener
extends Object implements GestureDetector.OnGestureListener, GestureDetector.OnDoubleTapListener, GestureDetector.OnContextClickListener

java.lang.Object
↳	android.view.GestureDetector.SimpleOnGestureListener

A convenience class to extend when you only want to listen for a subset of all the gestures. This implements all methods in the GestureDetector.OnGestureListener, GestureDetector.OnDoubleTapListener, and GestureDetector.OnContextClickListener but does nothing and return false for all applicable methods.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

GestureDetector.SimpleOnGestureListener

added in API level 1

GestureDetector.SimpleOnGestureListener ()

Public methods

onContextClick

added in API level 23

boolean onContextClick (MotionEvent e)

Notified when a context click occurs.

Parameters
`e`	`MotionEvent`: The motion event that occurred during the context click.

Returns
`boolean`	true if the event is consumed, else false

onDoubleTap

added in API level 3

boolean onDoubleTap (MotionEvent e)

Notified when a double-tap occurs.

Parameters
`e`	`MotionEvent`: The down motion event of the first tap of the double-tap.

Returns
`boolean`	true if the event is consumed, else false

onDoubleTapEvent

added in API level 3

boolean onDoubleTapEvent (MotionEvent e)

Notified when an event within a double-tap gesture occurs, including the down, move, and up events.

Parameters
`e`	`MotionEvent`: The motion event that occurred during the double-tap gesture.

Returns
`boolean`	true if the event is consumed, else false

onDown

added in API level 1

boolean onDown (MotionEvent e)

Notified when a tap occurs with the down MotionEvent that triggered it. This will be triggered immediately for every down event. All other events should be preceded by this.

Parameters
`e`	`MotionEvent`: The down motion event.

Returns
`boolean`

onFling

added in API level 1

boolean onFling (MotionEvent e1, 
                MotionEvent e2, 
                float velocityX, 
                float velocityY)

Notified of a fling event when it occurs with the initial on down MotionEvent and the matching up MotionEvent. The calculated velocity is supplied along the x and y axis in pixels per second.

Parameters
`e1`	`MotionEvent`: The first down motion event that started the fling.
`e2`	`MotionEvent`: The move motion event that triggered the current onFling.
`velocityX`	`float`: The velocity of this fling measured in pixels per second along the x axis.
`velocityY`	`float`: The velocity of this fling measured in pixels per second along the y axis.

Returns
`boolean`	true if the event is consumed, else false

onLongPress

added in API level 1

void onLongPress (MotionEvent e)

Notified when a long press occurs with the initial on down MotionEvent that trigged it.

Parameters
`e`	`MotionEvent`: The initial on down motion event that started the longpress.

onScroll

added in API level 1

boolean onScroll (MotionEvent e1, 
                MotionEvent e2, 
                float distanceX, 
                float distanceY)

Notified when a scroll occurs with the initial on down MotionEvent and the current move MotionEvent. The distance in x and y is also supplied for convenience.

Parameters
`e1`	`MotionEvent`: The first down motion event that started the scrolling.
`e2`	`MotionEvent`: The move motion event that triggered the current onScroll.
`distanceX`	`float`: The distance along the X axis that has been scrolled since the last call to onScroll. This is NOT the distance between `e1` and `e2`.
`distanceY`	`float`: The distance along the Y axis that has been scrolled since the last call to onScroll. This is NOT the distance between `e1` and `e2`.

Returns
`boolean`	true if the event is consumed, else false

onShowPress

added in API level 1

void onShowPress (MotionEvent e)

The user has performed a down MotionEvent and not performed a move or up yet. This event is commonly used to provide visual feedback to the user to let them know that their action has been recognized i.e. highlight an element.

Parameters
`e`	`MotionEvent`: The down motion event

onSingleTapConfirmed

added in API level 3

boolean onSingleTapConfirmed (MotionEvent e)

Notified when a single-tap occurs.

Unlike onSingleTapUp(MotionEvent), this will only be called after the detector is confident that the user's first tap is not followed by a second tap leading to a double-tap gesture.

Parameters
`e`	`MotionEvent`: The down motion event of the single-tap.

Returns
`boolean`	true if the event is consumed, else false

onSingleTapUp

added in API level 1

boolean onSingleTapUp (MotionEvent e)

Notified when a tap occurs with the up MotionEvent that triggered it.

Parameters
`e`	`MotionEvent`: The up motion event that completed the first tap

Returns
`boolean`	true if the event is consumed, else false
