此博客展示了一段Android开发代码，定义了一个名为MyAdapter的RecyclerView适配器类。该类导入了必要的包，包含上下文和数据列表，重写了onCreateViewHolder方法用于接收布局，体现了Android开发中适配器的基本实现。

package com.example.mvp3.adapter;

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import com.bumptech.glide.Glide;
import com.example.mvp3.R;
import com.example.mvp3.bean.Bean;

import java.util.List;

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
Context context;
List<Bean.ResultBean> list;

public MyAdapter(Context context, List<Bean.ResultBean> list) {
    this.context = context;
    this.list = list;
}

//     绑定
@NonNull
@Override

// 接收布局
public MyAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(context).inflate(R.layout.shou_layout, viewGroup, false);

    return new ViewHolder(view);
}

//设置数据
@Override
public void onBindViewHolder(@NonNull MyAdapter.ViewHolder viewHolder, int i) {
    Glide.with(context).load(list.get(i).getImageUrl()).into(viewHolder.imageView);
    viewHolder.textView.setText(list.get(i).getTitle());
    viewHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            recyclerviewListener.callBack(v.getId());
        }
    });
}

//返回数量
@Override
public int getItemCount() {
    return list.size();
}

//初始化试图
public class ViewHolder extends RecyclerView.ViewHolder {
    private ImageView imageView;
    private TextView textView;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);
        imageView = itemView.findViewById(R.id.images);
        textView = itemView.findViewById(R.id.texta);

    }
}

RecyclerviewListener recyclerviewListener;

public void setRecyclerviewListener(RecyclerviewListener recyclerviewListener) {
    this.recyclerviewListener = recyclerviewListener;
}

public interface RecyclerviewListener {
