本文介绍如何使用Retrofit框架结合RxJava实现Android应用中的网络请求功能，包括权限配置、依赖添加、API接口定义及请求数据的具体实现。

添加权限：

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

build.gradle:

compile 'com.squareup.retrofit2:retrofit:2.1.0'
//Gson converter
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
//RxJava2 Adapter
compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'
//okhttp
compile 'com.squareup.okhttp3:okhttp:3.4.1'
compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'

定义一个api接口：

public interface Api {
    @GET("weather/index?format=2&key=e7a94c85b65930fdb88bc0698416287c&cityname=北京")
    Observable<Bean> getUsers();
}
Mainactivity:
public class MainActivity extends AppCompatActivity {

    private static Retrofit retrofit;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Create();
        getData();
    }

    private void getData() {
        Api api = retrofit.create(Api.class);
        api.getUsers()
                .subscribeOn(Schedulers.io())               //在IO线程进行网络请求
                .observeOn(AndroidSchedulers.mainThread())  //回到主线程去处理请求结果
                .subscribe(new Observer<Bean>() {
                    @Override
                    public void onSubscribe(Disposable d) {
                        Log.d("nnn", d + "");

                    }

                    @Override
                    public void onNext(Bean value) {

                        Log.d("yyy", value.getResult().getFuture().get(0).getWeek());

                    }

                    @Override
                    public void onError(Throwable e) {
                        Toast.makeText(MainActivity.this, "登录失败", Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onComplete() {
                        Toast.makeText(MainActivity.this, "登录成功", Toast.LENGTH_SHORT).show();
                    }
                });
    }

    private static Retrofit Create() {
        OkHttpClient.Builder builder = new OkHttpClient().newBuilder();
        builder.readTimeout(10, TimeUnit.SECONDS);
        builder.connectTimeout(9, TimeUnit.SECONDS);

        if (BuildConfig.DEBUG) {
            HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
            builder.addInterceptor(interceptor);
        }

        retrofit = new Retrofit.Builder().baseUrl("http://v.juhe.cn/")
                .client(builder.build())
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .build();

        return retrofit;
    }
}
