方法详细资料

provideHandledTypes

@NonNull
protected java.util.Set<java.lang.Integer> provideHandledTypes()

指定者:

provideHandledTypes 在类中 ProgressiveGesture<RotateGestureDetector.OnRotateGestureListener>

analyzeMovement

protected boolean analyzeMovement()

覆盖:

analyzeMovement 在类中 MultiFingerGesture<RotateGestureDetector.OnRotateGestureListener>

canExecute

protected boolean canExecute(int invokedGestureType)

覆盖:

canExecute 在类中 MultiFingerGesture<RotateGestureDetector.OnRotateGestureListener>

gestureStopped

protected void gestureStopped()

覆盖:

gestureStopped 在类中 ProgressiveGesture<RotateGestureDetector.OnRotateGestureListener>

reset

protected void reset()

覆盖:

reset 在类中 MultiFingerGesture<RotateGestureDetector.OnRotateGestureListener>

getDeltaSinceStart

public float getDeltaSinceStart()

Returns rotation change in degrees since the start of the gesture.

返回:

rotation change since the start of the gesture

getDeltaSinceLast

public float getDeltaSinceLast()

Returns last rotation change difference in degrees calculated in RotateGestureDetector.OnRotateGestureListener.onRotate(RotateGestureDetector, float, float)

返回:

rotation change since last callback

getAngleThreshold

public float getAngleThreshold()

Get the threshold angle between first and current fingers position for this detector to actually qualify it as a rotation gesture.

返回:

Angle threshold for rotation gesture

setAngleThreshold

public void setAngleThreshold(float angleThreshold)

Set the threshold angle between first and current fingers position for this detector to actually qualify it as a rotation gesture.

参数:

angleThreshold - angle threshold for rotation gesture
