import com.google.gson.Gson;
import java.io.IOException;
import java.util.List;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.Response;//创建接口实现类 实现接口 重写接口中定义的方法
public class MyDataModel implements DataModel{//重写请求数据的方法
@Override
public void getData(String url, final DataPresenter presenter) {//使用OkHttp进行请求 重写失败与成功的方法
OkhtttpUtils.doGet(url, new Callback() {//失败
@Override
public void onFailure(Call call, IOException e) {}//成功
@Override
public void onResponse(Call call, Response response) throws IOException {//获取服务器返回的数据
String json = response.body().string();//使用Gson解析进行解析
Gson gson = new Gson();//得到解析后的数据
MyData myData = gson.fromJson(json, MyData.class);//得到解析后的list集合
List<MyData.DataBean> list = myData.getData();//调用P层的方法，将获取的数据集合传回P层
presenter.Success(list);}});}
}
4. Presenter层：1.接口； 2.实现类
package com.example.myshopping.presenter;
import com.example.myshopping.model.MyData;

package com.example.myshopping.presenter;
import com.example.myshopping.model.MyData;
import com.example.myshopping.model.MyDataModel;
import com.example.myshopping.view.DataView;
import java.util.List;//创建接口实现类 实现接口 重写接口中定义的方法
public class MyDataPresenter implements DataPresenter{//3.创建构建器 把V层传入到P层
DataView dataView;private final MyDataModel model;public MyDataPresenter(DataView dataView) {this.dataView=dataView;//4.实例化M层
model = new MyDataModel();}//成功 接收从M层传来的集合数据
@Override
public void Success(List<MyData.DataBean> list) {//5.调用V层接收数据的方法 把list集合传回m层
dataView.toBackHome(list);}//失败
@Override
public void Error() {}//1.定义接收数据接口url的方法
public void netWrok(String url){//6.调用m层请求数据的方法，将接口url和p层传到M层
model.getData(url,this);}
}
5. View层：1.接口； 2.实现类
package com.example.myshopping.view;

import java.util.List;public class MainActivity extends AppCompatActivity implements DataView{private ImageView my_icon;private RecyclerView my_rcy;private CheckBox my_cb;private TextView my_zj;private TextView my_js;int i=0;//用于判断图片的切换
//请求数据的接口
String url = "https://www.zhaoapi.cn/product/getProducts?pscid=1";//创建Handler
Handler handler = new Handler(){@Override
public void handleMessage(Message msg) {super.handleMessage(msg);//获取msg传来的数据 需强转
List<MyData.DataBean> list = (List<MyData.DataBean>) msg.obj;//设置适配器 将MainActivity和集合传给适配器
MyAdapter myAdapter = new MyAdapter(MainActivity.this,list);//将适配器设置到my_rcy上
my_rcy.setAdapter(myAdapter);}};@Override
protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//找到资源控件的ID
my_icon = findViewById(R.id.my_icon);//图片
my_rcy = findViewById(R.id.my_rcy);//布局
my_cb = findViewById(R.id.my_cb);//全选
my_zj = findViewById(R.id.my_zj);//总价
my_js = findViewById(R.id.my_js);//件数
//设置线性布局管理器 (工程一加载时，默认显示线性布局)
my_rcy.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));//给图片设置点击事件 实现点击图片时切换线性与表格布局
my_icon.setOnClickListener(new View.OnClickListener() {@Override
public void onClick(View view) {i++;//进行判断 当i%2==0时则显示线性布局，否则显示表格布局
if(i%2==0){//设置线性布局管理器
my_rcy.setLayoutManager(new LinearLayoutManager(MainActivity.this,LinearLayoutManager.VERTICAL,false));}else{//设置表格布局管理器
my_rcy.setLayoutManager(new GridLayoutManager(MainActivity.this,2));}}});//2.1实例化p层 将MainActivity(DataView)传给P层
MyDataPresenter presenter = new MyDataPresenter(this);//2.2调用传送url的方法
presenter.netWrok(url);}//7.接收P层传来的数据 因其在子线程中，所有需使用Handler更新ui
@Override
public void toBackHome(List<MyData.DataBean> list) {//创建Message对象
Message msg = new Message();//将list集合传入msg
msg.obj=list;//将msg传给handler
handler.sendMessage(msg);}

MyViewHolder myViewHolder = (MyViewHolder) holder;//为myViewHolder中的控件进行赋值
myViewHolder.rcy_title.setText(list.get(position).getTitle());//标题
myViewHolder.rcy_price.setText(list.get(position).getPrice()+"");//价格
myViewHolder.rcy_num.setText(list.get(position).getSellerid()+"");//数量
//使用Glide为图片赋值
String imgurl="http://www.ca-maimai.com/Public/kindeditor_images/image/20140828/20140828125439_54766.jpg";Glide.with(context).load(imgurl).into(myViewHolder.rcy_img);}//条目的数量

public class OkhtttpUtils {//单例模式，把构造方法进行私有化
public OkhtttpUtils(){};static OkHttpClient client;public static OkHttpClient getInstance(){if (client==null) {//更加安全
synchronized (OkhtttpUtils.class) {//缓存的地方 mnt/sdcard
File file = new File(Environment.getExternalStorageDirectory(), "cache11");client = new OkHttpClient().newBuilder().readTimeout(3000, TimeUnit.SECONDS) //设置读取超时时间
.connectTimeout(3000, TimeUnit.SECONDS) //设置连接的超时时间
.cache(new Cache(file, 10 * 1024)).build();}}return client;}/**
* get请求
* Callback 是一个接口
*/
public static void doGet(String url, Callback callback){//1:拿到okhttpclient 对像
OkHttpClient client = getInstance();//2:进行请求的操作
Request request = new Request.Builder().url(url).build();client.newCall(request).enqueue(callback);}//post请求
/**
*
* @param url 请求的地址
* @param parms 请求的参数
* @param callback callback
*/
public static void doPost(String url, Map<String,String> parms,Callback callback){//得到客户端的对像
OkHttpClient client = getInstance();//不是FormBody，而是一个Builder
FormBody.Builder body = new FormBody.Builder();//key value
for (String key:parms.keySet()){//value的值
body.add(key,parms.get(key));}Request request = new Request.Builder().url(url).post(body.build()).build();client.newCall(request).enqueue(callback);}//用来上传图片的
//url , 图片 ，参数 Callback
public static void upImage(String url,File file,String filenName,Map<String,String> params,Callback callback){OkHttpClient client = getInstance();//requestBody的实现类 Formbody
MultipartBody.Builder builder = new MultipartBody.Builder();if (params!=null){for (String key :params.keySet()){builder.addFormDataPart(key,params.get(key));}}//设置类型
builder.setType(MultipartBody.FORM);builder.addFormDataPart("file",filenName,RequestBody.create(MediaType.parse("application/octet-stream"),file));// builder.setType(MultipartBody.FORM);
// builder.addFormDataPart("file",filenName,RequestBody.create(MediaType.parse("application/octet-stream"),file));
