MVP新的使用方法

依赖

 //retrofi依赖
    compile 'com.squareup.retrofit2:retrofit:+'
    compile 'com.squareup.retrofit2:converter-gson:+'
    //Rxjava2需要依赖
    compile 'io.reactivex.rxjava2:rxjava:+'
    compile 'io.reactivex.rxjava2:rxandroid:+'

//让retrofit支持Rxjava2
    compile 'com.squareup.retrofit2:adapter-rxjava2:+'

user包
RetrofitApi类存放请求数据是拼接的网络路径

public interface RetrofitApi {
    @GET("user/login")
    Observable onLogin(@Query("mobile") String mobile, @Query("password") String password);

}

RetrofitMannager 类是为工具栏，只需要改变跟接口路径就行

/**
 * 封装Retrofit网络请求类
 */

public class RetrofitMannager {
    private static final String BASEURL = "http://120.27.23.105/";
    private static Retrofit mretrofit;
    private static RetrofitMannager retrofitMannager;

    //提供共有的方法供外界使用返回实例
    public static RetrofitMannager newinstance() {
        if (retrofitMannager == null) {
            retrofitMannager = new RetrofitMannager();
        }
        return retrofitMannager;
    }

    //构造器私有化
    private RetrofitMannager() {
        mretrofit = getRetrofit();
    }

    //构建自定义OkhttpClient
    private static OkHttpClient getOkhttpClient() {
        return new OkHttpClient.Builder()
                .connectTimeout(5000, TimeUnit.MILLISECONDS)
                .build();
    }

    //构建Retrofit
    private static Retrofit getRetrofit() {
        return new Retrofit.Builder().baseUrl(BASEURL)
                .client(getOkhttpClient())
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .build();
    }


    //通过动态代理返回网络请求接口实例
    public  T mreceat(Class t) {
        return mretrofit.create(t);
    }


}

model层
Model类是为了调用网咯请求数据的类

public class Model  {

    //请求数据返回RxJava被观察者
    public Observable onLogin(String mobile, String password) {
        return RetrofitMannager.newinstance().mreceat(RetrofitApi.class).onLogin(mobile, password);
}
}

view层
BaseIView类是v层接口的父类，为了方便创建更多v层接口

public interface BaseIView {
}

v层接口

public interface IView extends BaseIView {

    void onSucsse(LoginBean loginBean);

    void onError(Throwable throwable);

}

Iviews类是p层接口

public abstract class Iviews<T extends BaseIView> {
    protected T view;

    public Iviews(T view) {
        this.view = view;
        init();
    }

    protected abstract void init();
}

Iviews是p层的类

public class Passer extends Iviews {

    private Model model;

    public Passer(IView view) {
        super(view);
    }

    @Override
    protected void init() {
        model = new Model();
    }


    public void onLoad(String mobile, String password) {
        Observable loginBeanObservable = model.onLogin(mobile, password);

        loginBeanObservable
//                //被观察者在子线程请求数据
                .subscribeOn(Schedulers.io())
                //观察者在住线程发生数据给View层
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Consumer() {
                               @Override
                               public void accept(LoginBean loginBean) throws Exception {
                                   Passer.super.view.onSucsse(loginBean);
                               }
                           },

                        new Consumer() {
                            @Override
                            public void accept(Throwable throwable) throws Exception {

                            }
                        }
                );

    }

}
