tianbaojun opened a new issue #2855: Android BounceRecyclerView  
onRefreshingComplete调用后，某个cell会消失
URL: https://github.com/apache/incubator-weex/issues/2855
 
 
   ## Describe the bug
   weex写的稍微复杂的一个列表，android list组件进行下拉刷新后，某些item（cell）消失了。
   
   ## Environment
   Device: 华为p9  （所有手机都可以重现，但不是必现）
   OS: android 8.0（所有手机都可以重现，但不是必现）
   Version 0.18
   Build from source  yes
   
   ## Expected behavior
   刷新之后【服务商家】不应该消失
   
   ## Screenshots

   可以看到服务商家这个模块是丢失的。
   ## Additional context
   为了避免数据渲染导致的问题，我做了如下尝试。
   WXSwipeLayout的startRefresh方法中，我取消了 
onRefreshListener.onRefresh();的调用。但是【服务商家】item依然会消失。
    private void startRefresh(int headerViewHeight) {
       mRefreshing = true;
       ValueAnimator animator = ValueAnimator.ofFloat(headerViewHeight, 
refreshViewHeight);
       animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
         @Override
         public void onAnimationUpdate(ValueAnimator animation) {
           LayoutParams lp = (LayoutParams) headerView.getLayoutParams();
           lp.height = (int) ((Float) 
animation.getAnimatedValue()).floatValue();
           headerView.setLayoutParams(lp);
           moveTargetView(lp.height);
         }
       });
       animator.addListener(new WXRefreshAnimatorListener() {
         @Override
         public void onAnimationEnd(Animator animation) {
           headerView.startAnimation();
           //TODO updateLoadText
           if (onRefreshListener != null) {
             postDelayed(new Runnable() {
               @Override
               public void run() {
                 finishPullRefresh();
                 if(getParent() instanceof BaseBounceView) {
                   ((BaseBounceView) getParent()).onRefreshingComplete();
                 }
               }
             },2000);
           }
         }
       });
       animator.setDuration(300);
       animator.start();
     }
