Listener for scale gesture callbacks.

Method Summary

Modifier and Type	Method and Description
boolean	onScale(StandardScaleGestureDetector detector) Called for every scale change during the gesture.
boolean	onScaleBegin(StandardScaleGestureDetector detector) Indicates that the scale gesture started.
void	onScaleEnd(StandardScaleGestureDetector detector, float velocityX, float velocityY) Indicates that the scale gesture ended.

Method Detail

onScaleBegin

boolean onScaleBegin(StandardScaleGestureDetector detector)

Indicates that the scale gesture started.

Parameters:

detector - this detector

Returns:

true if you want to receive subsequent onScale(StandardScaleGestureDetector) callbacks, false if you want to ignore this gesture.

onScale

boolean onScale(StandardScaleGestureDetector detector)

Called for every scale change during the gesture.

Parameters:

detector - this detector

Returns:

Whether or not the detector should consider this event as handled.

onScaleEnd

void onScaleEnd(StandardScaleGestureDetector detector,
                float velocityX,
                float velocityY)

Indicates that the scale gesture ended.

Parameters:

detector - this detector

velocityX - velocityX of the gesture in the moment of lifting the fingers

velocityY - velocityY of the gesture in the moment of lifting the fingers
