Interface RotateGestureDetector.OnRotateGestureListener

All Known Implementing Classes:

RotateGestureDetector.SimpleOnRotateGestureListener

Enclosing class:

RotateGestureDetector

public static interface RotateGestureDetector.OnRotateGestureListener

Listener for rotate gesture callbacks.

Method Summary

Modifier and Type	Method and Description
boolean	onRotate(RotateGestureDetector detector, float rotationDegreesSinceLast, float rotationDegreesSinceFirst) Called for every rotation change during the gesture.
boolean	onRotateBegin(RotateGestureDetector detector) Indicates that the rotation gesture started.
void	onRotateEnd(RotateGestureDetector detector, float velocityX, float velocityY, float angularVelocity) Indicates that the rotation gesture ended.

Method Detail

onRotateBegin

boolean onRotateBegin(RotateGestureDetector detector)

Indicates that the rotation gesture started.

Parameters:

detector - this detector

Returns:

true if you want to receive subsequent onRotate(RotateGestureDetector, float, float) callbacks, false if you want to ignore this gesture.

onRotate

boolean onRotate(RotateGestureDetector detector,
                 float rotationDegreesSinceLast,
                 float rotationDegreesSinceFirst)

Called for every rotation change during the gesture.

Parameters:

detector - this detector

rotationDegreesSinceLast - rotation change since the last call

rotationDegreesSinceFirst - rotation change since the start of the gesture

Returns:

true if the gesture was handled, false otherwise

onRotateEnd

void onRotateEnd(RotateGestureDetector detector,
                 float velocityX,
                 float velocityY,
                 float angularVelocity)

Indicates that the rotation gesture ended.

Parameters:

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

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

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

detector - this detector
