package com.bwie.lenovo.mvpshop.model;import okhttp3.Callback;/** * Created by lenovo on 2017/11/21. */public interface IModel { public void initData(String path, Callback callback);}
Model实现接口的类
package com.bwie.lenovo.mvpshop.model;import com.bwie.lenovo.mvpshop.utils.OkHttp3Utils;import okhttp3.Callback;/** * Created by lenovo on 2017/11/21. */public class MyModel implements IModel { @Override public void initData(String path, Callback callback) { OkHttp3Utils.doGet(path,callback); }}View接口
package com.bwie.lenovo.mvpshop.view;import com.bwie.lenovo.mvpshop.bean.ShopBean;/** * Created by lenovo on 2017/11/21. */public interface MyView { public void getData(ShopBean shopBean);}
Presenter类
package com.bwie.lenovo.mvpshop.presenter;import android.content.Context;import com.bwie.lenovo.mvpshop.bean.ShopBean;import com.bwie.lenovo.mvpshop.model.MyModel;import com.bwie.lenovo.mvpshop.utils.OnUiCallback;import com.bwie.lenovo.mvpshop.view.MyView;import com.google.gson.Gson;import java.io.IOException;import okhttp3.Call;/** * Created by lenovo on 2017/11/21. */public class MyPresenter { Context context; MyView myView; MyModel myModel; public MyPresenter(Context context, MyView myView) { this.context = context; this.myView = myView; this.myModel = new MyModel(); } public void MyPresenter(String path){ myModel.initData(path, new OnUiCallback() { @Override public void onFailed(Call call, IOException e) { } @Override public void onSuccess(String result) { Gson gson=new Gson(); ShopBean shopBean=gson.fromJson(result, ShopBean.class); myView.getData(shopBean); } }); } public void deatch(){ myView=null; }}其中applaction中有ImagelLOader两个类
还有utils
拦截器LoggingInterceptor package com.bwie.lenovo.mvpshop.utils;import java.io.IOException;import okhttp3.FormBody;import okhttp3.Interceptor;import okhttp3.Request;import okhttp3.RequestBody;import okhttp3.Response;/** * Created by lenovo on 2017/11/22. */public class LoggingInterceptor implements Interceptor { @Override public Response intercept(Chain chain) throws IOException { //首先取到Request Request request=chain.request(); Response response=null; Request requestprocess=null; if("GET".equals(request.method())){ String url=request.url().toString()+ "&source=android"; Request.Builder builder=new Request.Builder(); builder.get().url(url); requestprocess=builder.build(); System.out.println(requestprocess); response=chain.proceed(requestprocess); }else{ FormBody.Builder builder=new FormBody.Builder(); RequestBody requestBody=request.body(); if (requestBody instanceof FormBody){ FormBody formBody= (FormBody) requestBody; for(int i=0;i<formBody.size();i++){ builder.add(formBody.encodedName(i),formBody.encodedValue(i)); } builder.add("source","android"); } requestprocess=request.newBuilder().url(request.url().toString()).post(builder.build()).build(); response=chain.proceed(requestprocess); } return response; }}
CustomerView类
