Android 回收器视图聚焦其他行中的另一个文本视图

在我的项目中，我有一个recycler视图，其中每一行都包含一个文本视图。当我在一行中选择一个文本视图时，一些随机行中的文本视图也会被选中，并且无论键入什么，它也会显示在这些行中。这是我的代码。 onBindViewHolder

public void onBindViewHolder(final MainContentViewHolder holder, int position) {
    Log.e("Sony","onBindViewHolder");
    Item currentItem = items.get(position);
    if (currentItem.imageURL != null) {
        imageLoader.get(currentItem.imageURL, new ImageLoader.ImageListener() {
            @Override
            public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
                Log.e("Sony","onResponseImage");
                holder.itemImage.setImageBitmap(response.getBitmap());
            }

            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e("Sony","onErrorImage");
                holder.itemImage.setImageResource(R.drawable.default_product);
            }
        });
    }
    //holder.itemImage.setImageBitmap(BitmapFactory.decodeStream((InputStream) new URL().getContent());

    holder.itemPrice.setText(currentItem.price + "");
    holder.itemName.setText(currentItem.itemName);
}

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

        itemImage = (ImageView) itemView.findViewById(R.id.imgItemPic);
        itemName = (TextView) itemView.findViewById(R.id.lblItemName);
        itemPrice = (TextView) itemView.findViewById(R.id.lblItemPrice);
        txtQty = (EditText) itemView.findViewById(R.id.txtQty);
        btnAddToCart = (Button) itemView.findViewById(R.id.btnAddToCart);
        btnAddToCart.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Item item = items.get(getPosition());
                CartMessageHandler.showToastMessage(context, item.itemName + " : " + item.price, Toast.LENGTH_LONG);
            }
        });
    }

public void onBindViewHolder(final MainContentViewHolder holder, int position) {
    Log.e("Sony","onBindViewHolder");
    Item currentItem = items.get(position);
    if (currentItem.imageURL != null) {
        imageLoader.get(currentItem.imageURL, new ImageLoader.ImageListener() {
            @Override
            public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
                Log.e("Sony","onResponseImage");
                holder.itemImage.setImageBitmap(response.getBitmap());
            }

            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e("Sony","onErrorImage");
                holder.itemImage.setImageResource(R.drawable.default_product);
            }
        });
    }
    //holder.itemImage.setImageBitmap(BitmapFactory.decodeStream((InputStream) new URL().getContent());

    holder.itemPrice.setText(currentItem.price + "");
    holder.itemName.setText(currentItem.itemName);
}

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

        itemImage = (ImageView) itemView.findViewById(R.id.imgItemPic);
        itemName = (TextView) itemView.findViewById(R.id.lblItemName);
        itemPrice = (TextView) itemView.findViewById(R.id.lblItemPrice);
        txtQty = (EditText) itemView.findViewById(R.id.txtQty);
        btnAddToCart = (Button) itemView.findViewById(R.id.btnAddToCart);
        btnAddToCart.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Item item = items.get(getPosition());
                CartMessageHandler.showToastMessage(context, item.itemName + " : " + item.price, Toast.LENGTH_LONG);
            }
        });
    }

创建时的活动

 mainListView = (RecyclerView) findViewById(R.id.recyclerList);
    mainListView.addItemDecoration(new DividerItemDecoration(this, DividerItemDecoration.VERTICAL_LIST));
    recyclerViewListAdapter = new MainContentRecyclerAdapter(this);
    mainListView.setAdapter(recyclerViewListAdapter);
    getData("fruits%20&%20vegetables");
    mainListView.setLayoutManager(new LinearLayoutManager(this));

我的代码有什么问题？有人能提出一种方法来修复这个问题吗？

RecyclerView重用先前创建的行视图。这就是为什么您会在RecyclerView的随机行中看到前面键入的文本：您只是不重置onBindViewHolder中的行视图内容状态

因此，为了避免错误，您应该在onBindViewHolder中重置组件状态：清除txtQty等。如果是昂贵或重量级的数据，建议使用文档发布此数据
