构造器详细资料

ShoveGestureDetector

public ShoveGestureDetector(android.content.Context context,
                            ShoveGestureDetector.OnShoveGestureListener 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

updateStateByEvent

protected void updateStateByEvent(android.view.MotionEvent curr)

覆盖:

updateStateByEvent 在类中 TwoFingerGestureDetector

isSloppyGesture

protected boolean isSloppyGesture(android.view.MotionEvent event)

从类复制的说明: TwoFingerGestureDetector

Check if we have a sloppy gesture. Sloppy gestures can happen if the edge of the user's hand is touching the screen, for example.

覆盖:

isSloppyGesture 在类中 TwoFingerGestureDetector

参数:

event - Motion Event

返回:

true if is sloppy gesture, false if not

getShovePixelsDelta

public float getShovePixelsDelta()

Return the distance in pixels from the previous shove event to the current event.

返回:

The current distance in pixels.
