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

Question

Answer 1

When you do the preference activity with a fragment, here is the solution that I used:

public class T2DPreferenceActivity extends PreferenceActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getFragmentManager().beginTransaction().replace(android.R.id.content,
            new T2DPreferenceFragment()).commit();
}

public static class T2DPreferenceFragment extends PreferenceFragment {
    @Override
    public void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.server_screen_preference);
    }

    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        ListView lv = (ListView)view.findViewById(android.R.id.list);
        ViewGroup parent = (ViewGroup)lv.getParent();
        parent.setPadding(0, 100, 0, 0);
    }
}

}
