`abstract boolean`	`onSingleTapConfirmed(MotionEvent e)` Notified when a single-tap occurs.

Public methods

onDoubleTap

Added in API level 3

public abstract boolean onDoubleTap (MotionEvent e)

Notified when a double-tap occurs. Triggered on the down event of second tap.

Parameters
`e`	`MotionEvent`: The down motion event of the first tap of the double-tap. This value cannot be `null`.

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

onDoubleTapEvent

Added in API level 3

public abstract 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. This value cannot be `null`.

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

onSingleTapConfirmed

Added in API level 3

public abstract boolean onSingleTapConfirmed (MotionEvent e)

Notified when a single-tap occurs.

Unlike OnGestureListener.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. This value cannot be `null`.

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