Android: How to maximize PreferenceFragment width (or get rid of margin)?

If you look at either Android Settings screenshot or FragmentsBC screenshot, there are margin in PreferenceFragment. How can you get rid of it?

I tried making PreferenceFragment width to fill_parent, but no luck.

Finally, I found the solution to this.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = super.onCreateView(inflater, container, savedInstanceState);
    if(v != null) {
        ListView lv = (ListView) v.findViewById(android.R.id.list);
        lv.setPadding(10, 10, 10, 10);
    }
    return v;
}

You can set padding by using: setPadding();
