Tabs fragment fetch data every time I change tab

Question

activity_profile.xml

Answer 1

If you go to 3rd tab then go to the 2nd or 1st tab then 1st will be recreated and call onCreate, that is the default behavior of fragment. But going to just 2nd tab and then back to 1st tab will not recreate the 1st tab. I have made some changes in the InterestTabFragment.java below only in onCreate. See if it helps, if not then notify me, I may try again. Thanks.....

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreateView(inflater, container, savedInstanceState);
    view = inflater.inflate(R.layout.interest_tab_fragment, container, false);

    listview = (HorizontalListView) view.findViewById(R.id.LVCategory);

        if(((ProfileActivity)getActivity()).interestResult.categories == null){
            Session session = Session.getActiveSession();
            if (session != null && session.isOpened()) {
                // Get the user's data
                access_token = session.getAccessToken();
                makeInterestRequest(session);
        }
        } else {
            CategoryLVAdapter adapter = new CategoryLVAdapter(getActivity(), R.layout.category_item_template,     ((ProfileActivity)getActivity()).interestResult.categories);

            listview.setAdapter(adapter);
        }


    return view;
}
