如何在onCreate（）之后在recyclerview中添加适配器

Question

我有一个RecyclerView设置，应该显示一个电影列表。问题是我在进行API调用后得到了数据。所以我的问题是：如何在我的Activity的onCreate方法之后设置数据？

＆＃13;

// Fragment

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_movie_overview, container, false);
        mRecyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view);

        mRecyclerView.setHasFixedSize(true);
        mLayoutManager = new LinearLayoutManager(getContext());
        mRecyclerView.setLayoutManager(mLayoutManager);
        movieOverviewPresenter.loadMovies();
        return rootView;
    }

    @Override
    public void showMovie(List<Movie> movies) {
        mAdapter = new MovieOverviewAdapter(movies);
        mRecyclerView.setAdapter(mAdapter);
    }

// Presenter

    @Override
    public void loadMovies() {
        retrofit.create(MovieService.class).getPopularMovies("API_KEY").subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .unsubscribeOn(Schedulers.io())
                .subscribe(new Observer<Result>() {
                    @Override
                    public void onCompleted() {
                        Log.i("Request", "Success!");
                    }

                    @Override
                    public void onError(Throwable e) {
                        Log.d("Request", "Error: " + e);
                    }

                    @Override
                    public void onNext(Result result) {
                        mView.showMovie(result.getResults());
                    }
                });
    }

Answer 1

在onResume（）中调用showMovie（）。

Answer 2

您必须通过在onComplete()回调中调用Group Value A 15 A 5 B 4 B 2 C 25 C 15 告诉适配器数据已在一段时间后更新。
