今天讲述团队项目第一阶段中对recyclerview的适配器配置，

package com.example.bowenwang;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

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

import com.bumptech.glide.Glide;

import java.util.List;

public class RecyclerAdapter2 extends RecyclerView.Adapter<RecyclerAdapter2.Hoder> {
    List<Bean> mlist;
    private Context mContext;
    public RecyclerAdapter2(List<Bean> mlist) {
        this.mlist = mlist;
    }
    @NonNull
    @Override
    public Hoder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        mContext=parent.getContext();
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View view=inflater.inflate(R.layout.list_item,parent,false);
        Hoder hoder=new Hoder(view);
        return hoder;
    }

    @Override
    public void onBindViewHolder(@NonNull Hoder holder, int position) {
        holder.title.setText(mlist.get(position).getTitle());
        holder.time.setText(mlist.get(position).getTime());
        holder.place.setText(mlist.get(position).getPlace());
        String img=mlist.get(position).getImg();
        if(img.equals("无")){
            Glide.with(mContext).load("http://n.sinaimg.cn/default/feedbackpics/transform/116/w550h366/20180326/gx3A-fysqfnf9556450.png").into(holder.img);
        }
        else {
            Glide.with(mContext).load(img.trim()).into(holder.img);
        }
        int p=position;
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Bean bean=new Bean();
                bean.setTitle(mlist.get(p).getTitle());
                bean.setTime(mlist.get(p).getTime());
                bean.setPlace(mlist.get(p).getPlace());
                bean.setContent(mlist.get(p).getContent());
                Toast.makeText(mContext,bean.getTitle(),Toast.LENGTH_SHORT).show();
                Intent iti=new Intent(mContext,DetailActivity.class);
                Bundle bundle = new Bundle();
                bundle.putSerializable("bean",bean);
                iti.putExtras(bundle);
                mContext.startActivity(iti);
            }
        });
    }

    @Override
    public int getItemCount() {
        return mlist.size();
    }
    class Hoder extends RecyclerView.ViewHolder{
         TextView title;
         TextView time;
         TextView place;
         ImageView img;
        public Hoder(@NonNull View itemView) {
            super(itemView);
            title=itemView.findViewById(R.id.tv_title);
            time=itemView.findViewById(R.id.tv_time);
            place=itemView.findViewById(R.id.tv_place);
            img=itemView.findViewById(R.id.iv_portrait);
        }
    }
}

 这里是我的团队项目中的适配器，可以看到后需要配置一些什么。
