如何在导航活动的导航抽屉中从其片段中写入用户名？

public class NavigationDrawerFragment extends Fragment {
    private TextView usernameTextView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_navigation_drawer, container, false);
        usernameTextView = rootView.findViewById(R.id.usernameTextView);

        // 从SharedPreferences获取用户名数据
        SharedPreferences sharedPreferences = getActivity().getSharedPreferences("UserData", Context.MODE_PRIVATE);
        String username = sharedPreferences.getString("username", "");

        // 设置用户名到TextView组件
        usernameTextView.setText(username);

        return rootView;
    }
}
