Make sure to call MenuCompat.setGroupDividerEnabled(menu, true); when you inflate your menu, otherwise groups will not be separated by divider!

Example:

@Override public boolean onCreateOptionsMenu(Menu menu) {     getMenuInflater().inflate(R.menu.menu_activity_main, menu);      MenuCompat.setGroupDividerEnabled(menu, true);      return true; } 

And make sure to have different groups in your menu xml, e.g.:

    <menu>         <group android:id="@+id/sorting" >             <item                 android:id="@+id/action_sorting_new_old"                 android:title="@string/action_sorting_new_old"/>              <item                 android:id="@+id/action_sorting_a_z"                 android:title="@string/action_sorting_a_z"/>         </group>          <group android:id="@+id/settings">             <item                 android:id="@+id/action_settings"                 android:title="@string/action_settings"/>         </group>     </menu>
