Android Preferences Screen inside Action Bar Tab - tabs

Question

I am developing some app with have ActionBar with three tabs, one of with is a settings tab.
PreferencesFragment loads my preferences xml file, so how can i add PreferenceFragment to ActionBar Tab ??
As at this picteur:
This is a main Activity that adds three tabs, I has added two simple fragments tab successfuly but a problem began with a RreferenceFragment
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final ActionBar actionBar = this.getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
Tab settings = actionBar.newTab();
settings.setText("Settings");
settings.setTabListener(new SettingsFragment());
actionBar.addTab(settings);
Tab control = actionBar.newTab();
control.setText("Controller");
control.setTabListener(new ControlFragment());
actionBar.addTab(control);
Tab information = actionBar.newTab();
information.setText("information");
information.setTabListener(new InformationFragment());
actionBar.addTab(information);
}
For example, this is a ControlFragment class ( second tab )
public class ControlFragment extends Fragment implements ActionBar.TabListener {
private Fragment fragment;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getActivity().setContentView(R.layout.control_fragment);
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction frgTransaction) {
//TODO
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction frgTransaction) {
fragment = new ControlFragment();
frgTransaction.add(android.R.id.content, fragment);
frgTransaction.attach(fragment);
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction frgTransaction) {
frgTransaction.remove(fragment);
}
}
And this is a SettingsFragment class with do the main problem
public class SettingsFragment extends PreferenceFragment implements ActionBar.TabListener {
private Activity act;
private Context context;
private Fragment fragment;
public SettingsFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preference_settings);
}
#Override
public void onTabReselected(Tab arg0, FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
#Override
public void onTabSelected(Tab arg0, FragmentTransaction arg1) {
// TODO Auto-generated method stub
fragment = new SettingsFragment();
arg1.add(android.R.id.content, fragment);
arg1.attach(fragment);
}
#Override
public void onTabUnselected(Tab arg0, FragmentTransaction arg1) {
// TODO Auto-generated method stub
}
}
Application crashes because its a problem to transact PreferenceFragment.
How I can inplement it ??? I know about TabHost but I use Action Bar.

You'd have to use the v13 support library to achieve this. Hope I helped.
