一.接口

1.ApiService  返回 Flowable观察者

import com.example.xx.rikao_09.bean.MessageBean;import com.example.xx.rikao_09.bean.Newslist;import java.util.List;import java.util.Map;import io.reactivex.Flowable;import retrofit2.http.GET;import retrofit2.http.QueryMap;public interface ApiService {    @GET("nba")    Flowable<MessageBean<List<Newslist>>> getNews(@QueryMap Map<String,String> map);}

2.MVP交互接口

public interface IView {    void OnSuccess(Object o);    void OnFailed(Exception e);}
public interface IPresenter {    void getData(Map<String,String> map);}
public interface IModel {    void getData(Map<String,String> map);}

二.RetrofitUtils   工具类
import retrofit2.Retrofit;import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;import retrofit2.converter.gson.GsonConverterFactory;public class RetrofitUtils {    private static volatile RetrofitUtils instance;    private final Retrofit retrofit;    private RetrofitUtils(){        retrofit = new Retrofit.Builder()                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())                .addConverterFactory(GsonConverterFactory.create())                .baseUrl("http://api.tianapi.com/")                .build();    }    public static RetrofitUtils getInstance(){        if(instance==null){            synchronized (RetrofitUtils.class){                if(instance==null){                    instance=new RetrofitUtils();                }            }        }        return instance;    }    public ApiService getApiService(){        ApiService apiService = retrofit.create(ApiService.class);        return apiService;    }}

三.M层
import com.example.xx.rikao_09.bean.MessageBean;import com.example.xx.rikao_09.bean.Newslist;import com.example.xx.rikao_09.http.RetrofitUtils;import com.example.xx.rikao_09.presenter.NewsPresenter;import java.util.List;import java.util.Map;import io.reactivex.Flowable;public class Model implements IModel{    private NewsPresenter presenter;    public Model(NewsPresenter presenter) {        this.presenter = presenter;    }    @Override    public void getData(Map<String, String> map) {        Flowable<MessageBean<List<Newslist>>> flowable = RetrofitUtils.getInstance().getApiService().getNews(map);        presenter.get(flowable);    }}


四.P层
import com.example.xx.rikao_09.bean.MessageBean;import com.example.xx.rikao_09.bean.Newslist;import com.example.xx.rikao_09.model.Model;import com.example.xx.rikao_09.view.IView;import java.util.List;import java.util.Map;import io.reactivex.Flowable;import io.reactivex.android.schedulers.AndroidSchedulers;import io.reactivex.schedulers.Schedulers;import io.reactivex.subscribers.DisposableSubscriber;public class NewsPresenter implements IPresenter{    private IView iView;    private DisposableSubscriber<MessageBean<List<Newslist>>> subscriber;    public void attachView(IView iView){        this.iView=iView;    }    @Override    public void getData(Map<String, String> map) {        Model model = new Model(this);        model.getData(map);    }    public void detachView(){        if(subscriber!=null){            //如果该资源已被处理，则可一次性返回true。如果没有被处理返回false            if(!subscriber.isDisposed()){                subscriber.dispose();            }        }    }        public void get(Flowable<MessageBean<List<Newslist>>> flowable){        subscriber = flowable.subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribeWith(new DisposableSubscriber<MessageBean<List<Newslist>>>() {                    @Override                    public void onNext(MessageBean<List<Newslist>> listMessageBean) {                        if (listMessageBean != null) {                            List<Newslist> newslist = listMessageBean.getNewslist();                            if (newslist != null) {                                iView.OnSuccess(newslist);                            }                        }                    }                    @Override                    public void onError(Throwable t) {                        iView.OnFailed(new Exception(t));                    }                    @Override                    public void onComplete() {                    }                });    }}

五.V层
import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import com.example.xx.rikao_09.R;import com.example.xx.rikao_09.bean.Newslist;import com.example.xx.rikao_09.presenter.NewsPresenter;import java.util.HashMap;import java.util.List;import java.util.Map;public class MainActivity extends AppCompatActivity implements IView {    private static final String TAG = "MainActivity";    private NewsPresenter Presenter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Presenter = new NewsPresenter();        Presenter.attachView(this);        Map<String,String> map = new HashMap<>();        map.put("key","71e58b5b2f930eaf1f937407acde08fe");        map.put("num","10");        Presenter.getData(map);    }    @Override    public void OnSuccess(Object o) {        if(o instanceof List){            List<Newslist> list= (List<Newslist>) o;            Log.e(TAG, "OnSuccess: "+list.size() );        }    }    @Override    public void OnFailed(Exception e) {        Log.e(TAG, "onFailed: " + e.getMessage());    }    @Override    protected void onDestroy() {        super.onDestroy();        if(Presenter!=null){            Presenter.detachView();        }    }}


五.依赖
//2.0 Rxjava    compile "io.reactivex.rxjava2:rxjava:2.1.7"    compile "com.squareup.retrofit2:adapter-rxjava2:2.3.0"    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'    //黄油刀    compile 'com.jakewharton:butterknife:8.8.1'    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'    //Retrofit    compile 'com.squareup.retrofit2:retrofit:2.3.0'//retrofit依赖    //compile 'com.squareup.retrofit2:converter-scalars:2.1.0 '//场景是这样，服务端返回一个不定类型的json数据，无法确定映射的Gson对象。    compile 'com.squareup.retrofit2:converter-gson:2.3.0'//retrofit内部封装的GSON    //compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'//log    //fresco    compile 'com.facebook.fresco:fresco:0.12.0'    // 在 API < 14 上的机器支持 WebP 时，需要添加    compile 'com.facebook.fresco:animated-base-support:0.12.0'    // 支持 WebP （静态图+动图），需要添加    compile 'com.facebook.fresco:animated-webp:0.12.0'    compile 'com.facebook.fresco:webpsupport:0.12.0'
