Summary
| Public methods |
| abstract Boolean |

Public methods
onDoubleTap
abstract fun onDoubleTap(e: MotionEvent): Boolean
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. |
| Return |
Boolean |
true if the event is consumed, else false |
onDoubleTapEvent
abstract fun onDoubleTapEvent(e: MotionEvent): Boolean
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. |
| Return |
Boolean |
true if the event is consumed, else false |
onSingleTapConfirmed
abstract fun onSingleTapConfirmed(e: MotionEvent): Boolean
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. |
| Return |
Boolean |
true if the event is consumed, else false |
