我从服务器获得了一个列表，并将其设置为适配器的RecyclerView。
因此，当我选择项目0 -〉时，所有项目都被选中/取消选中，在本例中，这是有效的。

但是当我选择了所有的项目，并且当我取消选择复选框1时，我期望取消选择复选框0。

适配器类

    // MY VIEW HOLDER CLASS ------------------------
    public class ViewHolder
            extends RecyclerView.ViewHolder {
        // Initialize variable
        CheckBox radioButton;
        TextView name_amlak;

            name_amlak = itemView.findViewById(R.id.item_vagozary_name_amlak);
            root = itemView.findViewById(R.id.root);
        }
    }

    public interface ItemClickListener {
        // Create method
        void onClick(String s);
    }

}

调用Main中的适配器

LinearLayoutManager layoutManager = new LinearLayoutManager(SelectedAmlakActivityV2, LinearLayoutManager.VERTICAL, false);
lists.setLayoutManager(layoutManager);
ClientsDataSet item = new ClientsDataSet();
item.name = "all";
apiClients.clients.add(0, item);

adapter = new VagozariSelectedAmlakAdapter(SelectedAmlakActivityV2, apiClients.clients, itemClickListener);
lists.setAdapter(adapter);

我简短的工作
#1：选择框0（因此选择列表中的所有项目）
#2：当我取消选择框1、2或3时，我想取消选择框0，这导致崩溃（在#1中）。
反过来说

尝试将holder.radioButton.setOnCheckedChangeListener(null);添加为onBindViewHolder()方法的第一行。
