How to pass data into fragment dynamically loaded into current activity

My activity contains "FrameLayout" element only.

In its 'onCreate' method I dynamically load fragment:

@Override
public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        UsersListFragment fragment = new UsersListFragment();

        FragmentManager fm = getSupportFragmentManager();
        FragmentTransaction ft = fm.beginTransaction();
        ft.add(R.id.fragment_container, fragment);
        ft.commit();
}

On some event my fragment communicates back to activity and I need to instantiate another fragment and pass some data to it. I do it in the activity by implementing special interface that is in turn called by fragment. It looks like this way:

@Override
public void onUserSelected(long userId) {

        UserDetailsFragment fragment = new UserDetailsFragment();

        FragmentManager fm = getSupportFragmentManager();
        FragmentTransaction ft = fm.beginTransaction();
        ft.replace(R.id.fragment_container, fragment);
        ft.addToBackStack(null);
        ft.commit();

        fragment.updateUser(userId);
}

As a result, "fragment.updateUser(userId);" is called way to early (fragment is not initialized yet, it is not attached to activity).

Question: what is the proper way to pass data into the fragment?

Thanks a lot in advance. Any thoughts are greatly appreciated.

P.S. I've seen a lot of examples that show how to load fragments, but was not able to find those that show how to pass data...

That usually happens to me: once wrote a question I got a new idea to try...

Looks like one of the possible options is to pass data by setting them via 'setArguments' method... and use during 'onCreateView' fragment method...

Any better options?
