The application I\'ve been developing uses ActionBarSherlock, and the main theme inherits from Theme.Sherlock.Light.DarkActionBar. The design requires that the overflow menu pop
In my research I haven't found a way to change the text color, but you can at least handle hardkey menus gracefully.
This link provided me with a passable solution to the problem: https://github.com/jgilfelt/android-actionbarstylegenerator/issues/30
Commenting out the "android:panelBackground" item from my generated theme allowed the text to at least be visible on hardkey menus, even if it doesn't perfectly match the theme.
You could also try replacing the "menu_hardkey_panel_whatever.9.png" drawable with something that will work for your theme and the black text.
