RecyclerView适配器类中Android View绑定的正确方法是什么? [英] What is the right way of Android View Binding in the RecyclerView adapter class?

问题描述

这是我在RecycleView适配器类中使用的代码.我不知道这是正确的方法还是不使用视图绑定.如果您有更好的解决方案，请回答我.谢谢.

Here is the code I used in my RecycleView adapter class. I don't know this is the right way or not to use View Binding. If you have a better solution answer me. Thank you.

@Override
public CategoryAdapter.MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.common_circle_image, parent, false);

    return new MyViewHolder(itemView);
}

@Override
public void onBindViewHolder(@NonNull CategoryAdapter.MyViewHolder holder, final int position) {
    holder.binding.img.setBackgroundResource(addAdapterData.get(position).getItemUrl());
    holder.binding.txt.setText(addAdapterData.get(position).getItemName());
}

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

public class MyViewHolder extends RecyclerView.ViewHolder {

    CommonCircleImageBinding binding;

    public MyViewHolder(@NonNull View itemView) {
        super(itemView);
        binding = CommonCircleImageBinding.bind(itemView);
        binding.cardView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                commonItemClick.onItemClick(getAdapterPosition(),"");
            }
        });
    }
}

此外，我想知道在同一个类中使用R.layout.layout_name和ViewBinding是正确的.

Also, I want to know is it right to use R.layout.layout_name and ViewBinding in the same class.

下面是Java中的完整视图绑定回收器视图代码，您可以像这样:

Here is full view binding recycler view code in java, you can do as like:

package com.jbws.myviewbindingdemo.adapter;

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;

import com.jbws.myviewbindingdemo.databinding.RowXmlViewBinding;
import com.jbws.myviewbindingdemo.pojo.ModelObject;

import java.util.ArrayList;

public class RecyclerViewListAdapter extends RecyclerView.Adapter<RecyclerViewListAdapter.ViewHolder> {
    public ArrayList<ModelObject> modelObjectArrayList;

    public RecyclerViewListAdapter(ArrayList<ModelObject> modelObjectArrayList) {
        this.modelObjectArrayList = modelObjectArrayList;
    }

    @NonNull
    @Override
    public RecyclerViewListAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        return new ViewHolder(RowXmlViewBinding.inflate(LayoutInflater.from(parent.getContext()),
                parent, false));
    }

    @Override
    public void onBindViewHolder(@NonNull RecyclerViewListAdapter.ViewHolder holder, final int position) {
        ModelObject modelObject = modelObjectArrayList.get(position);
        holder.rowXmlViewBinding.txtObjectName.setText(modelObject.getFullName());
        holder.rowXmlViewBinding.btnUpdateName.setOnClickListener(view -> {
         Log.i("LOG_TAG", "Full Name: " + modelObject.getFullName);
        });
    }

    @Override
    public int getItemCount() {
        return modelObjectArrayList == null ? 0 :
                modelObjectArrayList.size();
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        private RowXmlViewBinding rowXmlViewBinding;

        public ViewHolder(RowXmlViewBinding rowXmlViewBinding) {
            super(rowXmlViewBinding.getRoot());
            this.rowXmlViewBinding = rowXmlViewBinding;
        }
    }
}
