Android Swipe Gesture表示父Activity无法拦截

Question

我在Android滑动手势上工作，我在回收器视图中的物品上应用了滑动手势，回收者视图在片段内，然后片段在内部活动，活动有Scroll View，问题是父活动是拦截物品的滑动手势child recycler view，经过这么多努力我找到了解决方案并且这段代码工作正常，还有其他更好的解决方案吗？如果是，那么将其发布在答案中否则投票我的代码，以便我可以在我的应用程序中使用它，而不用担心失败。这是我的代码

      listingView.setOnTouchListener(new OnSwipeTouchListener(myContext)
        {


        public void onClick() {
            ViewListing();
        }
        //           @Override
        public boolean onTouch(View v, MotionEvent event) {


            switch (event.getActionMasked())
            {
                case MotionEvent.ACTION_DOWN:
                    x1 = event.getX();
                    break;
                case MotionEvent.ACTION_UP:
                    LockableScrollView.setScrollingEnabled(true);
                    break;
                case MotionEvent.ACTION_MOVE:
                    x2 = event.getX();
                    float deltaX = x2 - x1;

                    if (Math.abs(deltaX) > 20)
                    {
                        LockableScrollView.setScrollingEnabled(false);
                        // Left to Right swipe action
                        if (x2 > x1)
                        {
                            hideSidePanel();
                            LockableScrollView.setScrollingEnabled(true);

                        }

                        else
                        //MH: Right to Left Swipe
                        {

                            showSidePanel();
                            LockableScrollView.setScrollingEnabled(true);
                        }

                    }
                    break;

            }
            return super.onTouch(v, event);
        }


    });
