ViewModelProviders 在fragment中使用

@Override
    public View onCreateView(@NonNull LayoutInflater inflater, final ViewGroup container,
                             Bundle savedInstanceState) {
        MyViewModel viewModel;
        viewModel = ViewModelProviders.of(requireActivity(),new SavedStateViewModelFactory(getActivity().getApplication(),this)).get(MyViewModel.class);
        FragmentTitleBinding binding;
        binding = DataBindingUtil.inflate(inflater,R.layout.fragment_title,container,false);
        binding.setData(viewModel);
        binding.setLifecycleOwner(requireActivity());
        binding.button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                NavController controller = Navigation.findNavController(v);
                controller.navigate(R.id.action_titlefragment_to_question);
            }
        });
        return binding.getRoot();
        // Inflate the layout for this fragment
//        return inflater.inflate(R.layout.fragment_title, container, false);
    }
