android - Can't resolve getActionBarActivity() method -

i trying hide actionbar in activity. have activity fragment, looks this:

import android.app.activity; import android.app.actionbar; import android.app.fragment; import android.os.bundle; import android.view.layoutinflater; import android.view.menu; import android.view.menuitem; import android.view.view; import android.view.viewgroup; import android.os.build; public class introactivity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.intro_activity); if (savedinstancestate == null) { getfragmentmanager().begintransaction() .add(r.id.container, new placeholderfragment()) .commit(); actionbar actionbar = getsupportactionbar();<---- error here actionbar.hide(); } } @override public boolean oncreateoptionsmenu(menu menu) { // inflate menu; adds items action bar if present. getmenuinflater().inflate(r.menu.menu_intro, menu); homecoming true; } @override public boolean onoptionsitemselected(menuitem item) { // handle action bar item clicks here. action bar // automatically handle clicks on home/up button, long // specify parent activity in androidmanifest.xml. int id = item.getitemid(); //noinspection simplifiableifstatement if (id == r.id.action_settings) { homecoming true; } homecoming super.onoptionsitemselected(item); } /** * placeholder fragment containing simple view. */ public static class placeholderfragment extends fragment { public placeholderfragment() { } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view rootview = inflater.inflate(r.layout.intro_page_1, container, false); homecoming rootview; } } }

the error cannot resolve method getactionbaractivity method. have tried extending actionbaractivity, when do, oncreate errors, , several others.

how can hide action bar?

it not using back upwards library? if case should phone call getactionbar() not getsupportactionbar()
