android - onSwipe从左到右我得到标签ScrollView和无效的pointerId = -1 onTouchEvent

我在屏幕上左右滑动了一个事件，但是在touchEvent上有一个无效的pointerID=-1，在某些电话上，这个应用程序崩溃了，这里是我使用的类

   public class OnSwipeTouchListener implements OnTouchListener {
    private final GestureDetector gestureDetector = new GestureDetector(new GestureListener());
     @Override
     public boolean onTouch(View arg0, MotionEvent arg1) {
    // TODO Auto-generated method stub
    return gestureDetector.onTouchEvent(arg1);
     }
    private final class GestureListener extends SimpleOnGestureListener {

        private static final int SWIPE_THRESHOLD = 100;
    private static final int SWIPE_VELOCITY_THRESHOLD = 100;


        @Override
        public boolean onDown(MotionEvent e) {
         return true;
        }

       @Override
       public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)  {
          boolean result = false;
          try {
              float diffY = e2.getY() - e1.getY();
              float diffX = e2.getX() - e1.getX();

             if (Math.abs(diffX) > Math.abs(diffY)) {
                  if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffX > 0) {
                        onSwipeRight();
                    } else {
                        onSwipeLeft();
                    }
                }
              }
         } catch (Exception exception) {
            exception.printStackTrace();
        }
        return result;
    }


}

      public void onSwipeRight() {
      }

      public void onSwipeLeft() {
      }


}

我得到这个错误java.lang.IllegalargumentException:PointerIndex超出范围
在我的主要活动课上我用这个

fullView = (View)findViewById(R.id.fullview);
   fullView.setOnTouchListener(imageViewSwiped);  -> inside onCreate method

然后我用这个

     OnTouchListener imageViewSwiped = new OnSwipeTouchListener()
      {
     public void onSwipeRight() {

            minusOne();
        }
        public void onSwipeLeft() {
           // Toast.makeText(MainActivity.this, "left", Toast.LENGTH_SHORT).show();
            plusOne();
        }
};

最佳答案

我所做的只是评论了这个覆盖

     /*

    @Override
    public boolean onDown(MotionEvent e) {
     return true;
    }

      */

一切又完美了…
