本文介绍了如何在项目中引入Retrofit和RxJava库，通过创建服务接口来实现Get和Post网络请求。首先确保添加了必要的依赖，接着详细展示了配置过程和接口定义。

首先导入Rxjava与Retrofit依赖

compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.retrofit2:converter-scalars:2.1.0'
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex.rxjava2:rxjava:2.1.0'
compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'

创建Service服务接口

public interface GetService {

    //    http://gank.io/api/history/content/{1}/{1}
    @GET("content/{number}/{page}")
    Call<MyBean> getData(@Path("number") int n, @Path("page") int p);

    @GET("v2/movie/top250")
    Observable<MovieBean> getMovieData();
}

 Get请求方式不带参数

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.douban.com/")
        .addConverterFactory(GsonConverterFactory.create())
        .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
        .build();
Observable<MovieBean> observable = retrofit.create(GetService.class).getMovieData();
observable.subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(new Observer<MovieBean>() {
            @Override
            public void onSubscribe(@NonNull Disposable d) {

            }

            @Override
            public void onNext(@NonNull MovieBean movieBean) {
                recyclerView.setAdapter(new MyAdapter(movieBean.getSubjects(), MainActivity.this));
            }

            @Override
            public void onError(@NonNull Throwable e) {

            }

            @Override
            public void onComplete() {

            }
        });

Get请求方式带参数 
Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("http://gank.io/api/history/")
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        Call<MyBean> call = retrofit.create(GetService.class).getData(1, 1);
        call.enqueue(new Callback<MyBean>() {
            @Override
            public void onResponse(Call<MyBean> call, Response<MyBean> response) {
                MyBean bean = response.body();
//                recyclerView.setAdapter(new MyAdapter(bean.getResults(), MainActivity.this));

            }

            @Override
            public void onFailure(Call<MyBean> call, Throwable t) {

            }
        });

创建接口，post请求方式带参数
结合Rxjava形式
 //http://api.jisuapi.com/news/get?channel=头条&appkey=cf2efa79d8df0ede
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("http://api.jisuapi.com/news/")
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .build();
        HashMap<String, String> map = new HashMap<>();
        map.put("channel", "头条");
        map.put("appkey", "cf2efa79d8df0ede");
        Observable<RxBean> observable = retrofit.create(RxService.class).getRxData(map);
        observable.subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<RxBean>() {
                    @Override
                    public void onSubscribe(@NonNull Disposable d) {

                    }

                    @Override
                    public void onNext(@NonNull RxBean rxBean) {
//                            recyclerView.setAdapter(new MyAdapter(rxBean.getResult().getList(),MainActivity.this));
                    }

                    @Override
                    public void onError(@NonNull Throwable e) {

                    }

                    @Override
                    public void onComplete() {

                    }
                });
