@ Override
public boolean onCreateOptionsMenu (Menu menu) {
/ / Group1
int group1 = 1;
menu.add (group1, 1, 1, "g1.item1");
menu.add (group1, 2, 2, "g1.item2");

/ / Group2
int group2 = 2;
menu.add (group2, 3, 3, "g2.item1");
menu.add (group2, 4, 4, "g2.item2");
return true;
}

It uses a menu group effect
