Interface not reloaded after returning to app from BACK press

Issue

I currently have a set of tabs, each tied to a fragment, and I've finally gotten the UI on one of the tabs to look how it should. Here's a screenshot of how the app looks when it has properly loaded (after initial launch and scrolling to a tab): Now, after I hit the back button (I haven't and won't be bothering with a backStack for each tab - I don't like that UI paradigm) and then use app switcher or relaunch from the launcher, my questionRows are gone (they don't reload). Do I need to implement something in onPause to save my display? Why doesn't onResume take care of it this?

        //these lines are my first attempt to try and get the questions to repopulate after returning
        //from pressing back - as of yet, they don't repopulate the screen:

        pos++;
        TableRow tr = (TableRow) question;

    public void onDestroyView() {
        super.onDestroyView();
        Log.d("Econ", "ondestroyview");
    }

    public void onDestroy() {
        super.onDestroy();
        Log.d("Econ", "ondestroy");

    }

    public void onDetach() {
        super.onDetach();
        Log.d("Econ", "ondetach");
    }
}

Solution

The question kinda got put on the backburner as I worked on other areas of my app. It turns out the solution was a simple one: the pos variable as listed in the code was static, so the while loop could not reclimb from 0-10. Here's the answer: Even though onCreateView runs again, View does not properly reassemble after BACK press?
