    getFragmentManager().beginTransaction()
            .replace(R.id.content_frame, new SettingsPreference())
            .commit();

public static class SettingsPreference extends PreferenceFragment {
@Override
    public void onCreate(Bundle savedInstanceState) {
       // applyTheme();
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.pref_settings);
        android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) getActivity().findViewById(R.id.toolbar);
        ((ActionBarActivity)getActivity()).setSupportActionBar(toolbar);
