OK...my second attempt to find the device value of
textColorPrimaryDisableOnly:
TypedArray a = getTheme().obtainStyledAttributes(android.R.style.Theme, new

This unfortunately returns the same value on all devices.
My attempt at reflection didn't seem to work either:
Class myClass = Class.forName("android.R$styleable");

Looking for the background 9-patch was no more successful - I couldn't find
where menu_background_fill_parent_width.9.png is stored.
I did find android.R.drawable.ic_menu_more (the 'more' button that shows up
if you have > 6 menu items). I can sample the pixels on this and - hooray!
- the color range is different. Unfortunately not different enough to be
unambiguous in all situations and the approach is too wacky for comfort
anyway.
Anyone have any other ideas for reading the value of
textColorPrimaryDisableOnly?
