ListFragment List staying in the middle of the page

I'm having issues with my listFragment staying in the middle of the page. Like this:

http://ift.tt/1ckt4Ns

I'm using a listview in my xml document like this

<?xml version="1.0" encoding="utf-8"?>

<ListView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@android:id/list"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"/>

Which i'm pretty sure has no issues. But my Java i'm guessing is a little more dubious as i'm still learning.

public class menu_4_fragment extends ListFragment implements AdapterView.OnItemClickListener {
View rootview;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    // Basic way of implementing title, perhaps a better method should be used if found
    getActivity().getActionBar().setTitle("Settings");


    rootview = inflater.inflate(R.layout.menu4_layout, container, false);
    return rootview;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    // Brings the data from XML to view
    ArrayAdapter adapter = ArrayAdapter.createFromResource(getActivity(), R.array.Settings_strings, android.R.layout.simple_list_item_1);
    setListAdapter(adapter);
    getListView().setOnItemClickListener(this);

}

Can you guys see anything that's potential causing this issue? Or perhaps what would be a better way to implement this list frag? I'm having a bit of an issue implementing this in the first place as i've already got a fragmentation from my navigation drawer and most tutorials don't show how to implement a listview beyond that.

Thanks guys.
