Android rxjava和Retrofit的使用

1.第一步将Retrofit和Rxjava关联起来
public Retrofit getRetrofit(String baseUrl){
    Retrofit retrofit=new Retrofit.Builder()
            .client(setOkHttpClick())
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .addConverterFactory(GsonConverterFactory.create())
            .baseUrl(baseUrl)
            .build();
    return retrofit;

2.把Retrofit的返回值替换为Retrofit的Observer对象

public interface BeautyServer {
    @POST
    Observable getBeauty(@Url String url);
}
3.调用接口返回数据
RetrofitClient.getInstance().getRetrofit(BASE_URL).create(BeautyServer.class).getBeauty("api/today")
        .subscribeOn(Schedulers.newThread())
        .observeOn(Schedulers.io())//工作线程
        .doOnNext(new Action1() {
            @Override
            public void call(TodayNewsRes todayNewsRes) {
                Logger.d(todayNewsRes);
            }
        })
        .observeOn(AndroidSchedulers.mainThread())//切换为主线程返回数据
        .subscribe(new Subscriber() {
            @Override
            public void onCompleted() {

            }

            @Override
            public void onError(Throwable e) {

            }

            @Override
            public void onNext(TodayNewsRes todayNewsRes) {
                toastMsg(todayNewsRes.toString());
                //Logger.d(todayNewsRes.toString());
            }
        });
