监听一个view向左还是向右的滑动主要用到GestureDetector；
@Layout(R.layout.right_fragment_menu)public class RightFragment extends BaseFragment {@BindView(id=R.id.linout_right,canClick=true)private LinearLayout linout_right; private GestureDetector mGestureDetector;private SlidingMenu _SlidingMenu;public RightFragment(SlidingMenu _SlidingMenu){this._SlidingMenu=_SlidingMenu;}@Overridepublic void onActivityCreated(Bundle savedInstanceState) {super.onActivityCreated(savedInstanceState);//findView();}private void findView(){mGestureDetector = new GestureDetector(getActivity(), new MyOnGestureListener()); linout_right.setOnTouchListener(new OnTouchListener() {@Overridepublic boolean onTouch(View arg0, MotionEvent event) { //Log.i(getClass().getName(), "onTouch-----" + getActionName(event.getAction()));mGestureDetector.onTouchEvent(event);        // 一定要返回true，不然获取不到完整的事件        return true;}});}@Overrideprotected void onClick(View v) {}    class MyOnGestureListener extends SimpleOnGestureListener {        @Override        public boolean onSingleTapUp(MotionEvent e) {            return false;        }        @Override        public void onLongPress(MotionEvent e) {        }        @Override        public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {            return false;        }        @Override        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {            float moveX = e1.getX() - e2.getX();            // 左滑            if (moveX > 150 && moveX < 5000) {              // mDesignClothesBackground              // .setBackgroundResource(idClothesBackground[0]);            System.out.println("向左滑动");            }            // 右滑            else if (moveX < -150 && moveX > -5000) {              // mDesignClothesBackground              // .setBackgroundResource(idClothesBackground[1]);            System.out.println("向右滑动");            if(_SlidingMenu!=null){            _SlidingMenu.showContent();            }            }            return false;        }        @Override        public void onShowPress(MotionEvent e) {        }        @Override        public boolean onDown(MotionEvent e) {            return false;        }        @Override        public boolean onDoubleTap(MotionEvent e) {            return false;        }        @Override        public boolean onDoubleTapEvent(MotionEvent e) {            return false;        }        @Override        public boolean onSingleTapConfirmed(MotionEvent e) {            return false;        }    }}
