Summary
Public methods
onDoubleTap
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
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
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 |
