Android Swipe手势不可靠

Question

我在某种程度上滑动工作,但我有一系列的文字视图和旋转器在屏幕上,似乎我不直接划过其中一个,只是在他们两个之间,它不挑选它很好.总的来说,我认为它不会像iPhone上发生的那样好,我想知道是否有人可以批评我的代码并帮助我优化它.

我正在初始化GesureDectector和GestureListener.这是GestureListener类:

    public class GestureListener : Java.Lang.Object, GestureDetector.IOnGestureListener
    {
        private static int SWIPE_MAX_OFF_PATH = 250;
        private static int SWIPE_MIN_DISTANCE = 50;
        private static int SWIPE_THRESHOLD_VELOCITY = 200;
        private View view;
        private Activity act;

        public GestureListener(View _view, Activity _act)
        {
            view = _view;
            act = _act;
        }

        public bool OnDown( MotionEvent e )
        {
            return true;
        }

        public bool OnFling( MotionEvent e1, MotionEvent e2, float velocityX, float velocityY )
        {
            if ( Math.Abs( e1.GetY() - e2.GetY() ) > SWIPE_MAX_OFF_PATH ){
                return false;
            }
            if ( e1.GetX() - e2.GetX() > SWIPE_MIN_DISTANCE && Math.Abs( velocityX ) > SWIPE_THRESHOLD_VELOCITY ){
                HandleLeft();               
            }else if ( e2.GetX() - e1.GetX() > SWIPE_MIN_DISTANCE && Math.Abs( velocityX ) > SWIPE_THRESHOLD_VELOCITY ){
                HandleRight();
            }
            return false;
        }

        public void OnLongPress( MotionEvent e )
        {

        }

        public bool OnScroll( MotionEvent e1, MotionEvent e2, float distanceX, float distanceY )
        {
            return true;
        }

        public void OnShowPress( MotionEvent e )
        {

        }

        public bool OnSingleTapUp( MotionEvent e )
        {
            return true;
        }

        private void HandleLeft(){
            Male currActivity = (Male)act;
            currActivity.GetStrings("Female");
        }

        private void HandleRight(){
            Male currActivity = (Male)act;
            currActivity.GetStrings("Results");
        }
    }

我在OnTouch活动中使用它:

 public bool OnTouch(View v, MotionEvent e){
     bool handled = false;

     if(flingDetector != null){
    handled = flingDetector.OnTouchEvent(e);
     }

     if(v.GetType() == typeof(Spinner)){
    return !handled;    
     }else{
    return handled;
     }
 }

任何帮助将不胜感激.
