you can create a method to update ListView in Fragment

public void updateList(ArrayAdapter adapter){
    ListView listView = (ListView) rootView.findViewById(R.id.listView);
    list.setAdapter(arrayAdapter);
}

and call it from your Activity:

Fragment fragment = new Fragment();
fragment.updateList(someAdapter);

just don't call it in OnCreate method, because then fragment is not yet inflated.
