Notified when a double-tap occurs.
| e | The down motion event of the first tap of the double-tap. |
|---|
Notified when an event within a double-tap gesture occurs, including the down, move, and up events.
| e | The motion event that occurred during the double-tap gesture. |
|---|
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.
| e | The down motion event. |
|---|
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.
| e1 | The first down motion event that started the fling. |
|---|---|
| e2 | The move motion event that triggered the current onFling. |
| velocityX | The velocity of this fling measured in pixels per second along the x axis. |
| velocityY | The velocity of this fling measured in pixels per second along the y axis. |
Notified when a long press occurs with the initial on down MotionEvent
that trigged it.
| e | The initial on down motion event that started the longpress. |
|---|
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.
| e1 | The first down motion event that started the scrolling. |
|---|---|
| e2 | The move motion event that triggered the current onScroll. |
| distanceX | 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 | 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. |
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.
| e | The down motion event |
|---|
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.
| e | The down motion event of the single-tap. |
|---|
Notified when a tap occurs with the up MotionEvent
that triggered it.
| e | The up motion event that completed the first tap |
|---|
