this menu.xml :

<menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/menu_bantuan"     android:title="@string/menu_bantuan"     android:orderincategory="100"       android:showasaction="ifroom|withtext"/>    <item android:id="@+id/menu_exit"     android:title="@string/menu_exit"     android:orderincategory="100"     android:showasaction="ifroom|withtext" />    <item android:id="@+id/menu_logout"     android:title="@string/menu_logout"     android:orderincategory="100"     android:showasaction="ifroom|withtext" />

in main layout, i'm using header, giving effect menu, menu won't display or else?

i under assumption should first call super.

public boolean oncreateoptionsmenu(menu menu) {     super.oncreateoptionsmenu(menu);     menuinflater inflater = getmenuinflater();     inflater.inflate(r.menu.menu, menu);      return true; }

i assuming menu.xml has appropriate menu closing tag. have xml file stored in res/menu folder? can verify oncreateoptionsmenu called?

on android 2.3 , lower have press menu button, whereas in later distributions should displayed in title bar. since using tabactivity assume writing app android 2.3.

this question might useful onmenuitemselected() method: merge tabactivity menu contained activities menus

for activities within tabactivity: how create optionsmenu in android's tabactivity

perhaps when press menu button, options menu of specific tab activity in (e.g. loginactivity) called, , not of parent. try putting code in every subactivity:

public boolean oncreateoptionsmenu(menu menu) {     return getparent().oncreateoptionsmenu(menu); }
