添加依赖

compile 'io.reactivex:rxjava:1.1.0'
compile 'io.reactivex:rxandroid:1.1.0'
compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'
compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4'
compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4'
compile 'com.google.code.gson:gson:2.6.2'

使用代码

public class RxJavaActivity extends BaseActivity {

    private static final String BASE_URL = "http://www.tngou.net/tnfs/api/";
    Subscription subscription;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        //1.创建Retrofit对象
        Retrofit retrofit = new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create())//解析方法
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())//添加回调适配器广场
                .baseUrl(BASE_URL)//主机地址
                .build();

        //2.创建访问API的请求
        RequestService service = retrofit.create(RequestService.class);

        //3.订阅观察者
        subscription = service.getSingleImage("171")
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(observer);

    }

    Observer<SingleImageBean> observer = new Observer<SingleImageBean>() {
        @Override
        public void onCompleted() {
        }

        @Override
        public void onError(Throwable e) {
        }

        @Override
        public void onNext(SingleImageBean imageBean) {
            Log.v("-->", imageBean.toString());
        }
    };
}
public interface RequestService {

    //单独使用retrofit请求
    @GET("show")
    Call<SingleImageBean> getImage(@Query("id") String id);

    //rxjava+retrofit请求
    @GET("show")
    Observable<SingleImageBean> getSingleImage(@Query("id") String id);

}

请求结果

Rxjava+Retrofit 请求数据_ide
