片段Recyclerview onCreateView，onViewCreated或onActivityCreated？

Question

我應該在onCreateView，onViewCreated或onActivityCreated中初始化recyclerview嗎？

我搜索了這三者之間的區別是什么，但是有人說使用onCreateView，有人說使用onViewCreated或onActivityCreated而僅使用onCreateView來增加布局？

這是我的代碼

@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View rootView = inflater.inflate(R.layout.fragment_tab1, container, false);

    recyclerViewSongs = rootView.findViewById(R.id.recyclerViewSongs);

    initRecyclerView();

    Log.e(TAG, "onCreateView called!");

    return rootView;

}

private void initRecyclerView() {
    Main.musicList = Main.songs.songs;

    // Connects the song list to an adapter
    // (Creates several Layouts from the song list)
    allSongsAdapter = new AllSongsAdapter(getContext(), Main.musicList);

    final LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());

    recyclerViewSongs.setLayoutManager(linearLayoutManager);
    recyclerViewSongs.setHasFixedSize(true);
    recyclerViewSongs.setAdapter(allSongsAdapter);

    recyclerViewSongs.addOnItemTouchListener(new OnItemClickListeners(getContext(), new OnItemClickListeners.OnItemClickListener() {
            @TargetApi(Build.VERSION_CODES.O)
            @Override
            public void onItemClick(View view, int position) {
                Toast.makeText(getContext(), "You Clicked position: " + position, Toast.LENGTH_SHORT).show();
                if (! Main.songs.isInitialized())
                    return;
                //Start playing the selected song.
                playAudio(position);
            }
        }));

}

Answer 1

因為您正在使用Fragment所以onCreateView()將是最佳選擇。 區別在於onCreateView()是Activity的onCreate()的Fragment等效項，並且在創建View期間運行，而onViewCreated()在創建View之后運行。

然后在Activity onCreate()方法完成后調用onActivityCreated() ，如下所示： https : //stackoverflow.com/a/44582434/4409113

設置RecyclerView的最佳級別是onCreateView（），它等效於Activity的onCreate（），因為RecyclerView需要快速以免UI變慢。 因此，onViewCreated（）中的RecyclerView將在填充UI之前使UI變慢。
