我有一个 RecyclerView，每一行也有一个 EditText。我通过搜索将项目添加到 RecyclerView，然后在编辑文本中输入数量。然后我将它发送到服务器以使用 json 格式存储。项目添加工作正常。滚动时也没有编辑文本值交换问题。我可以在屏幕上显示 5 行。
问题是当我将项目发送到服务器时，底部行中的编辑文本值在第 5 行后变得相同。
这些是我添加到发送到服务器的 recyclerview.Printed 列表的行。
Item : 7.50-15 10PR FM CEAT Quantity : 1
Item : 5.60-15 04PR K 511 CEAT Quantity : 2
Item : 2.75-18 04PR SECURA F85 CEAT (F) Quantity : 3
Item : 3.00-17 06PR SECURA ZOOM CEAT (R) Quantity : 4
Item : 6.50-14 10PR FM CEAT Quantity : 5
Item : 5.00-12 04PR GRIP MASTER CEAT Quantity : 5
Item : 4.00-08 06PR AUTO RAJA RPG Quantity : 5
Item : 9.00-20 14PR CEAT CLT LUG Quantity : 5
Item : 8.25-20 14PR TR PLUS SUNTRAC Quantity : 5
Item : 7.00-15 12PR FM CEAT Quantity : 5
第5个位置后数量相同。我的输入值没有出现。

最佳答案
@Override
public void onBindViewHolder(@NonNull MyViewHolder holder, int position, @NonNull List<Object> payloads) {
super.onBindViewHolder(holder, position, payloads);
holder.setIsRecyclable(false);// set this in your adapter class as like it is
