The Android design guidelines<http://developer.android.com/design/style/iconography.html>for iconography say that disabled action bar icons should have an opacity 
of 30% (as opposed to enabled state with opacity 60% for the dark theme or 
80% for the light theme). The guidelines also state that action bar icons 
should be either a specific shade of gray or white (and not colored).

For coping with that issue I'm using following workaround:

menuItem.getIcon().setAlpha(enabled ? 255 : 64);
>

255 in case of enabled because my icon graphics already have the required 
opacity of 60%.
64 for the disabled icon state because it looked best in my case (using a 
light theme).

Actually I was expecting that there is some default behavior that takes 
care of that automatically. But I'm getting the impression that Google 
simply lets some room for individual theme customizations that have nothing 
much in common with the guidelines - like for example colored action bar 
items and different disabled state looks.
