Extending Menu Items on all screens for android . -

i using actionbarsherlock. using following code have created menu home screen

@override public boolean oncreateoptionsmenu(menu menu) {    menuinflater inflater = getsupportmenuinflater();    inflater.inflate(r.layout.menu, menu);    return super.oncreateoptionsmenu(menu); } @override public boolean onoptionsitemselected(menuitem item) {     switch (item.getitemid()) {         case r.id.about:             intent = new intent(this, aboutapp.class); // start about.java activity             startactivity(i);             return true;         case r.id.feedback:             intent j = new intent(this, sendfeedback.class);              startactivity(j);             return true;        default:             return super.onoptionsitemselected(item);     } } 

how extend menu screens across entire app ?

create baseclass extends activity (or fragmentactivity) , let other sublcass it.

otherclass extends baseclass 

since baseclass extends sherlockfragmentactivity, otherclass extends too.
