如何正确处理RecyclerView位置？

Question

我正在使用recyclerview，并且在其适配器内有另一个recyclerview。

如何在更新项目时防止项目更改和项目刷新。 这会造成视觉故障和物品的错误定位

我试图直接从数据库参考中读取持有人当前位置的信息。

我的回复适配器：

    }

    @NonNull
    @Override
    public RepliesAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.all_replies_layout, viewGroup, false);

        mAuth = FirebaseAuth.getInstance();
        return new RepliesAdapter.ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull final ViewHolder holder, final int position)
    {
final Replies replies = mReplies.get(position);

        holder.myUserName.setText(replies.getUsername());
        holder.myComment.setText(replies.getReply());
        holder.myTime.setText(replies.getTime());
    }


    @Override
    public int getItemCount() {

        return mReplies.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        public TextView myUserName, myComment,myTime;


        public ViewHolder(View itemView) {
            super(itemView);

            myUserName = itemView.findViewById(R.id.reply_username);

        }
