exoplayer中的java Recyclerview不起作用

Question

我的应用程序在framelayout中使用exo player，并带有显示服务器列表的recyclerview，所以问题是，当我点击播放器上的任意位置时，通常会隐藏诸如play pause progressbar fullscrn等控件，但应用程序会崩溃，但如果我在点击播放器上的任意位置之前单击recyclerview，一切都会正常工作，就像recyclerview隐藏一样，就像exoplayer中的其他控件一样

simpleExoPlayerView.setControllerVisibilityListener(new PlayerControlView.VisibilityListener() {
        @Override
        public void onVisibilityChange(int visibility) {
            Log.e("Visibil", String.valueOf(visibility));
            if (visibility==0){
                rvServer.setVisibility(VISIBLE);
                imgBack.setVisibility(VISIBLE);
                imgFull.setVisibility(VISIBLE);
                if (listSub.size()!=0) {
                    imgSubtitle.setVisibility(VISIBLE);
                }
            }else {
                rvServer.setVisibility(GONE);
                imgBack.setVisibility(GONE);
                imgFull.setVisibility(GONE);
                imgSubtitle.setVisibility(GONE);
            }
        }
    });
