好吧，我正在使用包含音频文件的Recyclerview，当我点击任何项目时，音频播放工作正常，但搜索栏没有更新！最后一个位置项搜索栏正在更新和播放。我没有找到确切的解决方案。这是我的代码。
RecyclerAdapter
public class AudiorecyclerAdapter extends RecyclerView.Adapter<AudiorecyclerAdapter.MyViewHolder> {

public AudiorecyclerAdapter(Context context,Activity act,List<GettingAudio> list){
this.datalist=list;
this.context=context;
this.act=act;
}

View v= LayoutInflater.from(parent.getContext()).inflate(R.layout.listreff,parent,false);
return new MyViewHolder(v);
}

{
holder.title.setText(datalist.get(position).getTitle());

答案 0 :(得分：0)
使用seekBar =（SeekBar）itemView.findViewById（R.id.seekBar）;在Onclick
实施例
public void onClick(View v){
seekBar=(SeekBar)itemView.findViewById(R.id.seekBar);
.......
//Yourcode
}
