java - exoplayer 中的 Recyclerview 不起作用

Question

我的应用程序在 framelayout 中使用 exo 播放器，并带有一个显示服务器列表的 recyclerview，所以问题是当我单击播放器上的任何位置时，通常会隐藏控件，如播放暂停进度条 fullscrn 等 recyclerview，但应用程序崩溃但如果我在单击播放器上的任何位置之前单击 recyclerview 一切正常，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);
            }
        }
    });



<FrameLayout
        android:id="@+id/player_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <com.google.android.exoplayer2.ui.PlayerView

            app:controller_layout_id="@layout/custom_controls"
            />
        <LinearLayout

            android:background="@color/transparent"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
        <ImageView
            android:id="@+id/img_subtitle"

            android:layout_height="wrap_content"
            android:layout_marginEnd="50dp" />
    </FrameLayout>
