如何使用视图模型将数据从DialogFragment发送到片段

public class SharedViewModel extends ViewModel {
    private MutableLiveData<String> data = new MutableLiveData<>();

    public void setData(String value) {
        data.setValue(value);
    }

    public LiveData<String> getData() {
        return data;
    }
}

public class MyDialogFragment extends DialogFragment {
    private SharedViewModel sharedViewModel;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        sharedViewModel = new ViewModelProvider(requireActivity()).get(SharedViewModel.class);
    }

    private void sendDataToFragment() {
        String dataToSend = "Hello Fragment!";
        sharedViewModel.setData(dataToSend);
    }
}

public class MyFragment extends Fragment {
    private SharedViewModel sharedViewModel;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        sharedViewModel = new ViewModelProvider(requireActivity()).get(SharedViewModel.class);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // 观察数据变化
        sharedViewModel.getData().observe(getViewLifecycleOwner(), new Observer<String>() {
            @Override
            public void onChanged(String data) {
                // 处理数据变化
                // 在这里更新片段中的UI或执行其他操作
            }
        });

        return inflater.inflate(R.layout.fragment_my, container, false);
    }
}
