我的游戏中有两个滑块，分别旋转和缩放+定位玩家精灵。
左滑块旋转精灵和右缩放 + 以一定速度移动玩家
我已经包含了 MultiTouch 扩展
问题是；
当我先触摸左滑块（先旋转）然后再触摸第二个即右滑块时，一切正常。但是，当我先触摸右侧滑块，然后再触摸左侧时，会发生旋转，但在视觉上看不到旋转。
可能是什么问题？如果需要，请分享代码
ONAREATOUCHED 的旋转滑块代码
@Override
public boolean onAreaTouched(TouchEvent touchEvent,float pTouchAreaLocalX,float pTouchAreaLocalY) {
mPlayer.clearRotationModifiers();
float currentRotationValue;
if(touchEvent.isActionDown())
{
//gesture detector enabled for rotation slider only
mGestureDetector.onTouchEvent(touchEvent.getMotionEvent());
this.LastPositionTouched=touchEvent.getMotionEvent().getY();
currentRotationValue=this.CalculateCurrentCalibratedValue(pTouchAreaLocalY);
mPlayer.MakeRotation(currentRotationValue);
mPlayer.pressedPlayerActionOnRotation=1; //press started
}
if( touchEvent.isActionMove() )
{
this.DistanceConveredSinceLastDownEvent=touchEvent.getMotionEvent().getY()-this.LastPositionTouched;
if( Math.abs(this.DistanceConveredSinceLastDownEvent) > HUDBar.minScrollDistanceCovered ){
mPlayer.pressedPlayerActionOnRotation=1;
currentRotationValue=this.CalculateCurrentCalibratedValue(pTouchAreaLocalY);
mPlayer.MakeRotation(currentRotationValue);
}
this.LastPositionTouched=touchEvent.getMotionEvent().getY();
}
if(touchEvent.isActionUp())
{
this.LastPositionTouched=0;
MainActivity.this.mPlayer.pressedPlayerActionOnRotation=0; //pressing stopped
mPlayer.resetRotation(-90);
//----reset debug variables-----
}
return true;
}

我将 GestureListener 的 onLongPress 用于 Rotation Slider，并为深度滑块编写了自定义 onLongPress，因为手势侦听器不支持 MultiTouch。我在播放器精灵上执行 onLongPress、OnScroll 事件
