Question

我对rxJava非常陌生，我想使用Retrofit将2个api调用按顺序链接在一起。但是不断出现此错误：无法为rx创建调用适配器。方法xx可观察到。以下是我的代码的一部分：

            ServiceA
            .subscribeOn(rx.schedulers.Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .flatMap(new Func1<ResponseA, Observable<ResponseB>>() {
                @Override
                public rx.Observable<ResponseB> call(ResponseA fooA) {
                    // code to save data from service A to db

                    // call service B
                    return ServiceB;
                }
            })
            .subscribe(new Subscriber<ResponseB>() {
                @Override
                public void onCompleted() {
                }

                @Override
                public void onError(Throwable e) {

                }

                @Override
                public void onNext(ResponseB fooB) {
                    // code to save data from service B to db

                }
            });


 Retrofit retrofit = new Retrofit.Builder().baseUrl("xxx")
                  .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();


compile 'io.reactivex:rxandroid:1.1.0'
compile 'io.reactivex:rxjava:1.1.3'   
compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'
compile 'com.squareup.retrofit2:retrofit:2.2.0'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'

您需要执行类似的操作

    val loginRequest = retrofitService.login(params)
loginRequest
        .flatMap { response ->
            saveLoginInfo(response.data)
            return@flatMap retrofitService.getProfile(params) }
        .flatMap { response ->
            doSomethingWithProfile(response.data)
            return@flatMap retrofitService.getItems(params) }
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe (
            { response ->
                doSomethingWithItems(response.data)
                doSomethingInMainThread()
            },
            { err -> Log.v("TAG", err.localizedMessage) },
            { Log.v("TAG", "Chains Completed") }
        )
