我应该在 onCreateView、onViewCreated 还是 onActivityCreated 中初始化我的 recyclerview？
这 3 个之间有什么区别，我搜索了解释，但有些人说使用 onCreateView 而有些人说使用 onViewCreated 或 onActivityCreated 并且只使用 onCreateView 来扩充布局？
这是我的代码
@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);
}
}));
}
最佳答案
onCreateView() 将是最佳选择，因为您正在使用 Fragment。不同之处在于 onCreateView() 是 Fragment 等同于 onCreate() 的 Activity 并在 View 创建期间运行但是 onViewCreated() 在 View 创建之后运行。
并且 onActivityCreated() 在 Activity 的 onCreate() 方法完成后调用，如您在此处所见:https://stackoverflow.com/a/44582434/4409113
