android - Fragment must be attached to a SherlockFragmentActivity -

ok have slight problem in code.

public class menufragment extends sherlocklistfragment { 

is extending sherlock jar should allow me use action bar within fragment when run code getting

 caused by: java.lang.illegalstateexception: menufragment must attached sherlockfragmentactivity. 

so changed extends

public class mainactivity extends actionbaractivity { 

to

   public class mainactivity extends sherlockfragmentactivity{ 

which runs code action bar no longer visible

my fragment class,

public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {         sethasoptionsmenu(true);         return view;     } @override     public void oncreateoptionsmenu(menu menu, menuinflater inflater) {         super.oncreateoptionsmenu(menu, inflater);         inflater.inflate(r.menu.menu_main, menu);     }     @override     public boolean onoptionsitemselected(com.actionbarsherlock.view.menuitem item){         switch (item.getitemid()) {             case r.id.shuffle:                  return true;             case r.id.quit:                  return true;             default:                 return false;         }     } 

which importing

import com.actionbarsherlock.app.sherlocklistfragment; import com.actionbarsherlock.view.menu; import com.actionbarsherlock.view.menuinflater; 

main

public class mainactivity extends actionbaractivity {     songadapter adapter;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);     } } 

hmmm instead of

mainactivity extends actionbaractivity

just use

   mainactivity extends sherlockfragmentactivity {     //you code fragment goes here     } 

whatever use fragment ned use sherlockfragment, in case of activity have sherlockactivity in here. else not match.
