构造器详细资料

RotateGestureDetector

public RotateGestureDetector(android.content.Context context,
                             RotateGestureDetector.OnRotateGestureListener listener)

方法详细资料

handleStartProgressEvent

protected void handleStartProgressEvent(int actionCode,
                                        android.view.MotionEvent event)

从类复制的说明: BaseGestureDetector

Called when the current event occurred when NO gesture is in progress yet. The handling in this implementation may set the gesture in progress (via gestureInProgress) or out of progress

指定者:

handleStartProgressEvent 在类中 TwoFingerGestureDetector

参数:

actionCode - Action Code from MotionEvent

event - MotionEvent

handleInProgressEvent

protected void handleInProgressEvent(int actionCode,
                                     android.view.MotionEvent event)

从类复制的说明: BaseGestureDetector

Called when the current event occurred when a gesture IS in progress. The handling in this implementation may set the gesture out of progress (via gestureInProgress).

指定者:

handleInProgressEvent 在类中 TwoFingerGestureDetector

参数:

actionCode - Action Code from MotionEvent

event - MotionEvent

resetState

protected void resetState()

覆盖:

resetState 在类中 BaseGestureDetector

getRotationDegreesDelta

public float getRotationDegreesDelta()

Return the rotation difference from the previous rotate event to the current event.

返回:

The current rotation //difference in degrees.
