MVP+Retrofit+Okhttp+RxJava

App的build.gradle依赖包：

         

compile ‘com.squareup.retrofit2:retrofit:2.0.0-beta4’//Retrofit2所需要的包
compile ’com.squareup.retrofit2:converter-gson:2.0.0-beta4’//ConverterFactory的Gson依赖包
compile ’com.squareup.retrofit2:converter-scalars:2.0.0-beta4’//ConverterFactory的String依赖包
compile ’com.facebook.fresco:fresco:0.11.0’
compile ’io.reactivex.rxjava2:rxjava:2.0.1’
compile ’io.reactivex.rxjava2:rxandroid:2.0.1’
compile ’com.squareup.retrofit2:adapter-rxjava2:2.3.0’

接口地址类：

public class API {

    //接口：APIKEY=‘71e58b5b2f930eaf1f937407acde08fe’     http://api.tianapi.com/nba/?key=APIKEY&num=10
    public static final String HOST=“http://api.tianapi.com/nba/”;

    //接口：http://result.eolinker.com/umIPmfS6c83237d9c70c7c9510c9b0f97171a308d13b611?uri=homepage
    public static final String BASE_URL= “http://result.eolinker.com/”;
    public static final String TOKEN= “umIPmfS6c83237d9c70c7c9510c9b0f97171a308d13b611”;
}

public interface ServiceAPI {
        @GET(API.HOST)
   //   Call  getNews(@Query(“key”)String n,@Query(“num”) int i);
        public Flowable getNews(@Query(“key”)String n,@Query(“num”) int i);


      //  @GET(“{token}”)
     //   public Flowable> homepage(@Path(“token”) String token, @Query(“uri”) String uri);
}

对Retrofit的封装：

public class RetrofitHelper {
 private   static OkHttpClient client;
  private   static ServiceAPI serviceAPI;

    static {
          getClient();
    }
    public static OkHttpClient getClient(){
        if(client==null){
            synchronized (OkHttpClient.class){
                if(client==null){
                    client=new OkHttpClient();
                }
            }
        }
        return client;
    }

    public static ServiceAPI getServiceAPI(){
        if(serviceAPI==null){
            synchronized (ServiceAPI.class){
                if(serviceAPI==null){
                     serviceAPI=onCreate(ServiceAPI.class,API.HOST);
                }
            }
        }
        return serviceAPI;
    }


    public static   T onCreate(Class tclass, String url){

        Retrofit build = new Retrofit.Builder()
                .baseUrl(url)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .client(client)
                .build();

       return build.create(tclass);
    }
}

封装Bean类省略

MVP

Model层：

public interface CGSB {
    void chengGong(T t);
    void shiBai(Call call);
}

public interface NewsModelJK {
   void getNews(String url, int i, CGSB cgsb);
}

public class NewsModel implements NewsModelJK {


    public void getNews(String url, int i, final CGSB cgsb){

        Flowable obserable = RetrofitHelper.getServiceAPI().getNews(url, i);//被观察者

        obserable.subscribeOn(Schedulers.io())//被观察者       Scheduler （调度器）

                  .observeOn(AndroidSchedulers.mainThread())       //观察者 切换到主线程
                  .subscribe(new Consumer() {
                      @Override
                      public void accept(NewsBean newsBean) throws Exception {
                          //调用成功的方法
                          cgsb.chengGong(newsBean);
                      }
                  });

    }
}

P层：

 

public interface INews {
    void showBean(NewsBean newsBean);
}

public class NewsPersenter {

    private final NewsModel newsModel;
    private INews iNews;
    public NewsPersenter(INews iNews) {

    }
    public  void getNews(final String n, int i){
        newsModel.getNews(n, i, new CGSB() {
            @Override
            public void chengGong(NewsBean newsBean) {
                iNews.showBean(newsBean);
            }

            @Override
            public void shiBai(Call call) {

            }
        });
    }
}

public class MainActivity extends AppCompatActivity implements INews {

    private XRecyclerView mXrlv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        NewsPersenter newsPersenter = new NewsPersenter(this);
        newsPersenter.getNews(”71e58b5b2f930eaf1f937407acde08fe”, 10);
        /**

         */
        initState();


    }

    @Override
    public void showBean(NewsBean newsBean) {
   //     Log.i(“Tag”, newsBean.getMsg());
        List newslist = newsBean.getNewslist();
        mXrlv.setLayoutManager(new LinearLayoutManager(this));
        MyAdapter myAdapter = new MyAdapter(newslist, this);
        mXrlv.setAdapter(myAdapter);

    }

    private void initView() {
        mXrlv = (XRecyclerView) findViewById(R.id.xrlv);

    }
    /**

    private void initState() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
