我正在向服务器发送一个简单的get方法,并使用RxJava和Retrofit获得结果。我所做的是:
接口
public interface Posts {
@GET("/typicode/demo/{path}")
Observable<List<Beans>> getPosts(@Path("path") String path);
}
RetrofitInstance
public static Retrofit getInstance() {
if (retrofit == null) {
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
retrofit = new Retrofit.Builder().baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.createWithScheduler(Schedulers.io()))
.client(client)
.build();
}
return retrofit;
}
主要活动
Observer<List<Beans>> observer = new Observer<List<Beans>>() {
@Override
public void onSubscribe(Disposable d) {
}
@Override
public void onNext(List<Beans> value) {
Log.d("Saket", value.toString());
}
@Override
public void onError(Throwable e) {
}
@Override
public void onComplete() {
}
};
Posts client = RetrofitClientInstance.getInstance().create(Posts.class);
client.getPosts("posts").observeOn(Schedulers.newThread()).subscribeOn(AndroidSchedulers.mainThread()).subscribe(observer);
我正在使用
HTTPLoggingInterceptor
获得正确的输出。 最佳答案
您可以像这样使用subscribeWith
也更改订阅-> Schedulers.newThread()或Schedulers.io()
现在,您正在通过UI线程进行网络调用
client.getPosts("posts")
.subscribeOn(Schedulers.newThread()) // change
.observeOn(AndroidSchedulers.mainThread()) // change
.subscribeWith(new Observer<Response<Observable<List<Beans>>>() {
@Override
public void onSubscribe(Disposable d) {
}
@Override
public void onNext(Response<Observable<List<Beans>>> response) {
}
@Override
public void onError(Throwable e) {
e.printStackTrace();
}
@Override
public void onComplete() {
}
});
关于java - Retrofit2 + RxJava向OnNext()中的Model类返回null,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/57268956/
