Question

我试图通过改装和rxAndroid从网上获取值，但是onNext没有被调用。在这里，我的课程：

public class ForumService {

private static final String FORUM_SERVER_URL = "http://192.168.1.104:8080/curso-fullstack/symfony/web";
private ForumApi mForumApi;


public ForumService(){
    RequestInterceptor requestInterceptor = new RequestInterceptor() {
        @Override
        public void intercept(RequestFacade request) {
            request.addHeader("Accept", "application/json");
        }
    };

    RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint(FORUM_SERVER_URL)
            .setRequestInterceptor(requestInterceptor)
            .setLogLevel(RestAdapter.LogLevel.FULL)
            .build();

    mForumApi = restAdapter.create(ForumApi.class);

}

public ForumApi getmForumApi() {
    return mForumApi;
}

public interface ForumApi{

    @GET("/video/lasts_videos")
    public Observable<List<Data>> getVideos();

    /*@GET("/posts/{id}")
    public Observable<Post>
    getPost(@Path("id") int postId);

    @GET("/comments")
    public Observable<List<Comment>>
    getComments(@Query("postId") int postId);

    @POST("/posts")
    public Observable<Post> postPost(Post post);*/
}

}

public class ListPresenter {

ListActivity mView;
ForumService mForum;

public ListPresenter(ListActivity mView, ForumService mForum) {
    this.mView = mView;
    this.mForum = mForum;
}

public void loadPosts() {

    mForum.getmForumApi()
            .getVideos()
            .subscribeOn(Schedulers.newThread())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Observer<List<Data>>() {
                @Override
                public void onCompleted() {

                }

                @Override
                public void onError(Throwable e) {

                }

                @Override
                public void onNext(List<Data> posts) {

                    mView.displayPosts(posts);
                }
            });
}

}

然后，我从我的活动中执行方法loadPosts()，以填充列表并在ListView中显示。如果我查看android日志，我可以看到改装如何向我显示找到结果，但由于任何原因onNext永远不会被调用。

从评论中的讨论：

onError因为JSON反序列化存在问题而未被调用。 public void moveRectangleTo(int x, int y) { box.setLocation(x, y); repaint(); }被调用了。

onNext不称为Retrofit和rxAndroid
