android - 与recyclerview的数据绑定(bind)我需要帮助。找不到root

Question

       public class Orderlist_recyclerview_adapter extends    
        RecyclerView.Adapter<Orderlist_recyclerview_adapter.MyViewHolder> {

        private Context mContext;
         private ArrayList<Orderlist_contents_bindingmodel> mUsersList = null;

    private LayoutInflater inflater;

    public Orderlist_recyclerview_adapter(Context context, ArrayList<Orderlist_contents_bindingmodel> usersList) {
        mContext = context;
        mUsersList= usersList;
        inflater = LayoutInflater.from(mContext);
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
//       View view = inflater.inflate(R.layout.each_row,viewGroup,false);
        OrderlistAdapterContentsBinding binding = OrderlistAdapterContentsBinding.inflate(inflater);
        MyViewHolder myViewHolder = new MyViewHolder(binding);
        return myViewHolder;
    }

    @Override
    public void onBindViewHolder(MyViewHolder myViewHolder, int i) {
        Orderlist_contents_bindingmodel user = mUsersList.get(i);
        myViewHolder.vBinding.setOrderlist_model(user);
    }

    @Override
    public int getItemCount() {
        return mUsersList.size();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder {
        OrderlistAdapterContentsBinding vBinding;
        public MyViewHolder(OrderlistAdapterContentsBinding binding) {
            **super(binding.getRoot());**here is the error
            this.vBinding = binding;
        }
     }
    }

我需要知道如何将 recyclerview 适配器模型与行布局绑定(bind)。

我已经声明了这些东西

<data>
    <variable name="orderlist_model" type="anpi.com.propuesta.binding_models.Orderlist_contents_bindingmodel" />
</data>

我有 TextView ，但仍然会出现这样的错误:

• 未找到 (text=@{..}) 的资源类型
• 找不到绑定(bind) .getroot

虽然这个问题似乎很久以前就被问过了，但还是发布了这个问题。添加

import android.databinding.ViewDataBinding;

对我有用。
