一、依赖

compile 'com.google.code.gson:gson:2.6.2'
compile 'com.squareup.okhttp3:okhttp:3.3.0'
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.jcodecraeer:xrecyclerview:1.5.9'
implementation files('libs/AMap_Location_V3.8.0_20180201.jar')
implementation files('libs/Amap_2DMap_V5.2.0_20170627.jar')
implementation files('libs/Android_Map3D_SDK_V6.0.1_20180309.jar')

二、权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.test">

    <uses-permission android:name="android.permission.INTERNET" />

    </application>

</manifest>

三、布局

activity_main.xml

<com.jcodecraeer.xrecyclerview.XRecyclerView
        android:id="@+id/recylerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

</com.jcodecraeer.xrecyclerview.XRecyclerView>

activity_detail.xml

<ImageView

    android:id="@+id/detail_pic"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:scaleType="centerCrop" />

<TextView
    android:id="@+id/detail_title"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="商品名" />

<TextView
    android:id="@+id/detail_address"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="北京" />

address_layout.xml（地图页面布局）

<com.amap.api.maps2d.MapView
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

layout_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">
    <ImageView
        android:id="@+id/item_pic"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:src="@mipmap/ic_launcher" />
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <TextView
            android:id="@+id/item_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="商品名称"
            android:textSize="25sp" />
        <TextView
            android:id="@+id/item_price"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="商品价格"
            android:textSize="20sp" />
    </LinearLayout>
</LinearLayout>

四、代码（四个包：http、model、presenter、view）

MainActivity

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.util.Log;
import android.view.View;
import android.view.Window;
import com.example.shixun1_monthtest.R;
import com.example.shixun1_monthtest.model.GoodsBean;
import com.example.shixun1_monthtest.model.ModelImpl;
import com.example.shixun1_monthtest.model.MyAdapter;
import com.example.shixun1_monthtest.presenter.PresenterImpl;
import com.jcodecraeer.xrecyclerview.XRecyclerView;
import java.util.List;

public class MainActivity extends AppCompatActivity implements IMainView {

    private XRecyclerView recyclerView;
    private static final String TAG = "MainActivity----";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
        initViews();
        initData();
    }
    private void initData() {
        PresenterImpl presenter = new PresenterImpl();
        presenter.showGoodsListToView(new ModelImpl(), this);
    }

    private void initViews() {
        recyclerView = findViewById(R.id.recylerview);
        //设置
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
    }

    //显示数据的方法
    @Override
    public void showGoodsList(final List<GoodsBean.DataBean> list) {
        Log.d(TAG, "showGoodsList: " + list);
        MyAdapter myAdapter = new MyAdapter(this, list);
        myAdapter.setMyItemClickListener(new MyAdapter.MyItemClickListener() {
            @Override
            public void onItemClick(View view, int postion) {
                Intent intent = new Intent(MainActivity.this, DetailActivity.class);
                String pic_url = list.get(postion).getImages().split("\\|")[0];
                intent.putExtra("pic_url", pic_url);
                intent.putExtra("title", list.get(postion).getTitle());
                startActivity(intent);
                finish();
            }
        });
        recyclerView.setAdapter(myAdapter);
    }
}

model下

GoodsBean（用接口请求数据）
( https://www.zhaoapi.cn/product/getProducts?pscid=1 )

IModel

public interface IModel {
    //获取商品数据
    void getGoodsList(String url, GetGoodsListener getGoodsListener);
}

MyAdapter

import android.content.Context;
import android.support.v7.widget.RecyclerView;

import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.bumptech.glide.Glide;
import com.example.shixun1_monthtest2.R;
import java.util.List;
/**

 */
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {

    private final Context context;
    private final List<GoodsBean.DataBean> list;
    public MyItemClickListener myItemClickListener;

    public MyAdapter(Context context, List<GoodsBean.DataBean> list) {
        this.context = context;
        this.list = list;
    }
    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = View.inflate(context, R.layout.layout_item, null);
        MyViewHolder myViewHolder = new MyViewHolder(view);
        return myViewHolder;
    }
    @Override
    public void onBindViewHolder(MyViewHolder holder, final int position) {
        String pic_url = list.get(position).getImages().split("\\|")[0];
        Glide.with(context).load(pic_url).into(holder.getItem_pic());
        holder.getItem_title().setText(list.get(position).getTitle());
        holder.getItem_price().setText("价格："+list.get(position).getBargainPrice());
        //这是条目点击事件
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                myItemClickListener.onItemClick(v,position);
            }
        });
    }
    @Override
    public int getItemCount() {
        return list.size();
    }
    //ViewHodler
    class MyViewHolder extends RecyclerView.ViewHolder {
        private final ImageView item_pic;
        private final TextView item_title,item_price;
        public MyViewHolder(View itemView) {
            super(itemView);
            item_pic = itemView.findViewById(R.id.item_pic);
            item_title = itemView.findViewById(R.id.item_title);
            item_price = itemView.findViewById(R.id.item_price);
        }
        public ImageView getItem_pic() {
            return item_pic;
        }
        public TextView getItem_title() {
            return item_title;
        }
        public TextView getItem_price() {
            return item_price;
        }
    }
    //自己定义条目点击事件
    public interface MyItemClickListener{
        void onItemClick(View view, int postion);
    }
    public void setMyItemClickListener(MyItemClickListener myItemClickListener){
        this.myItemClickListener = myItemClickListener;
    }
}

import java.util.List;
public class PresenterImpl implements IPresenter {
    @Override
    public void showGoodsListToView(IModel iModel, final IMainView iMainView) {

        String url = HttpConfig.url+"?pscid=1";

        iModel.getGoodsList(url, new GetGoodsListener() {
            @Override
            public void getGoodsSuccess(String json) {
                Gson gson=new Gson();
                GoodsBean goodsBean = gson.fromJson(json, GoodsBean.class);
                List<GoodsBean.DataBean> data = goodsBean.getData();
                //将数据传入View
                iMainView.showGoodsList(data);
            }
            @Override
