在view中设置tag，有2种方法，

public void setTag(final Object tag)
    
     public void setTag(int key, final Object tag)

这里用到了根据key设置tag，直接用的整数，就如上所述异常；

看提示，很明显了，说不能直接用整数作为key，要使用资源id，这是为了保证此整数的唯一性；

解决方案也很简单，在资源中添加ids.xml文件，添加上自命名的id：

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <item name="id_libvlc" type="id"/>
        <item name="id_mediaplayer" type="id"/>
    
    </resources>

再set get tag 就解决了：

videoLayout.setTag(R.id.id_libvlc, LibVLC);
    videoLayout.setTag(R.id.id_mediaplayer, mediaPlayer);
    
    
    LibVLC libVLC = (LibVLC) holder.vlcVideoLayout.getTag(R.id.id_libvlc);
    MediaPlayer mediaPlayer = (MediaPlayer) holder.vlcVideoLayout.getTag(R.id.id_mediaplayer);

好了，又可以愉快玩耍了。
