How can I refresh the ActionBar when onPrepareOptionsMenu switched menu entries?

Question

Within my apps I often enable/disable menu entries and do make them visible from onPrepareOptionsMenu.

Today I started to add the android:showAsAction menu attribute

Answer 1

Based on "Klaasvaak" answer above. I am using its subMenus. This works for me :

// Declare and save the menu as global, so it can be called anywhere.
Menu absTopSubMenus;

public boolean onCreateOptionsMenu(Menu menu) {

absTopSubMenus = menu;  // Used for re-drawing this menu anywhere in the codes.

// The remainder of your code below
}

Then, to re-draw this, just call :

// Redraw the top sub-menu
absTopSubMenus.clear();
onCreateOptionsMenu(absTopSubMenus);
