android - MediaController(this) 中出现错误，因为我在适配器类中使用了 this

Question

在 MediaController(this) 中出现错误，因为我在适配器类中使用它在回收器视图中显示视频。你能帮我找出我得到的错误的原因吗？

这是我的实现：

class VersionAdapter(val versionList:List<Versions>):RecyclerView.Adapter<VersionAdapter.VersionVM>() {

  class VersionVM (itemView: View):RecyclerView.ViewHolder(itemView){

    var codeNameText:TextView=itemView.findViewById(R.id.codename)
    var video11:VideoView=itemView.findViewById(R.id.version)
    var linearLayout:LinearLayout=itemView.findViewById(R.id.linearLayout)
    var expandable_layout:RelativeLayout=itemView.findViewById(R.id.expandable_layout)
  }

  override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): VersionVM {
    val view:View=LayoutInflater.from(parent.context).inflate(R.layout.list_item,parent,false)
    return VersionVM(view)
  }


  override fun onBindViewHolder(holder: VersionVM, position: Int) {
    val versions:Versions=versionList[position]
    holder.codeNameText.text=versions.videoName
    holder.video11.setVideoURI(Uri.parse(versions.version.toString()))

    holder.video11.start()


    val isExpandable:Boolean=versionList[position].expandable
    holder.expandable_layout.visibility=if (isExpandable) View.VISIBLE else View.GONE
    holder.linearLayout.setOnClickListener {
        val versions = versionList[position]
        versions.expandable = !versions.expandable
        notifyItemChanged(position)
    }
 }
}

提前致谢！
