Setting text as "primary" in Android

While looking through the built in Android themes/st开发者_运维问答yles I noticed references to textColorPrimary, textColorSecondary etc. I would like to implement this in to my own theme but cannot find any way of setting a textview (or any view) to "primary" or "secondary" etc.

Am I overlooking something or is it not possible to be done?

The references you're seeing to "textColor_____" are references to color selectors. You use them with a line like 'android:textColor="?android:textColorSecondary"' in the xml definition of your TextView.
