Android Studio 中的 onFling

如何解决Android Studio 中的 onFling

我正在尝试实现滑动来控制音量。问题是音量一次增加或减少一步，因此音量需要多次滑动。它不像通常的滑动那样快速反应。

private AudioManager mAudioManager; 
mAudioManager = (AudioManager) getApplicationContext().getSystemService(Context.AUdio_SERVICE);
 private final class GestureListener extends GestureDetector.SimpleOnGestureListener {

    private static final int SWIPE_THRESHOLD = 100;
    private static final int SWIPE_VELociTY_THRESHOLD = 100;
      @Override
    public boolean onFling(MotionEvent e1,MotionEvent e2,float veLocityX,float veLocityY) {
        int halfWidth = getwindow().getDecorView().getWidth() / 2;
            float diffY = e2.getY() - e1.getY();
            float diffX = e2.getX() - e1.getX();

        boolean result = false;
        
            if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(veLocityY) > SWIPE_VELociTY_THRESHOLD) {
                if (e1.getX() > halfWidth) {
                    if (diffY > 0) {
                        mAudioManager.adjustVolume(AudioManager.ADJUST_LOWER,AudioManager.FLAG_PLAY_SOUND);
                        

                    } else {
                        mAudioManager.adjustVolume(AudioManager.ADJUST_RAISE,AudioManager.FLAG_PLAY_SOUND);
                                               }
                    result = true;
                }
            }
        } catch (Exception exception) {
            exception.printstacktrace();
        }
        return result;
    }
}

它应该如何改变以期望的方式做出反应？
