在写毕设的过程中，想要实现如图，在recycleview中每个item都有一个播放按钮，播放属于自己的那一段音频。正常应该是点击第一个在播放过程中时，点击第二个就会停止第一个，然后播放第二个，但是现在虽然可以立马停止，但是imagebutton的改变跟不上，我在网上搜索得到，说notifyitemchange，可以刷新，但是在模拟器中也只有第一次生效，而在我的手机上则第一次也没有成功变化图标，所以想请问大神们，这个功该如何实现，下面是我的recycleview中adapter的实现。

public class RecordDdapter extends RecyclerView.Adapter<RecordDdapter.ViewHolder> {

    private static final String TAG = "adapter";
    private List<RecordData> mRecordData ;
    private Context mContext;

    private MediaPlayer player ;
    private boolean mStartPlaying = true;
    private int mposition;




    public RecordDdapter(Context context,List<RecordData> recordData) {
        mContext = context;
        mRecordData = recordData;
    }

    static class ViewHolder extends RecyclerView.ViewHolder{
        TextView date;
        ImageButton startbutton;
        TextView noisetime;
        TextView averagedb;
        TextView maxdb;
        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            date = itemView.findViewById(R.id.date);
            noisetime = itemView.findViewById(R.id.noise_time);
            averagedb = itemView.findViewById(R.id.average_db);
            maxdb = itemView.findViewById(R.id.max_db);
            startbutton = itemView.findViewById(R.id.play);
        }
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout,parent,false);
        ViewHolder viewHolder =new ViewHolder(view);
        return viewHolder;

    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, @SuppressLint("RecyclerView") int position) {
        RecordData recordData = mRecordData.get(position);
        holder.date.setText(recordData.getMdate());
        holder.maxdb.setText(recordData.getMaxdb()+"");
        holder.averagedb.setText(recordData.getAveragedb()+"");



        holder.startbutton.setOnClickListener(new View.OnClickListener() {
           final String noisepath = recordData.getPath();
            @Override
            public void onClick(View view) {

                if (mStartPlaying) {
                    Log.d(TAG, "onClick: start运行开始" +mposition+mStartPlaying);
                    startPlaying(noisepath, holder.startbutton);
                     mposition = position;
                    Log.d(TAG, "onClick: start运行结束" +mposition+mStartPlaying);
                } else {
                    if(mposition == position)
                    {
                        stopPlaying(holder.startbutton);
                        Log.d(TAG, "onClick: 正常stop"+mposition+mStartPlaying);
                    }
                    else
                    {
                        Log.d(TAG, "onClick: 点击其他的stop开始"+mposition+mStartPlaying);
                        player.release();//不管如何都要把上一个player给终结了
                        notifyItemChanged(mposition);
                        mposition = position;
                        startPlaying(noisepath, holder.startbutton);
                        Log.d(TAG, "onClick: 点击其他的stop结束"+mposition+mStartPlaying);
                    }

                }

                player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

                    @Override
                    public void onCompletion(MediaPlayer mp) {

            player.prepareAsync();//异步装载，不会让页面卡顿，但是用了异步装载就用用下面的回调函数

            });        //不然可能会没有装载完成就start了
        } catch (IOException e) {
