Hey Nick,
that's the thing. It's not that easy.
Checkout what I wrote in my initial post:
<item name="colorBackground">@android:color/background_dark</item>
<item
name="textColorPrimary">@android:color/primary_text_dark</item>
They basically look the same right? And they are both public, right?
However so far I have only been able to pry the RGB values from the
framework's hands for the first, but not the second.
And I think it's my fault. It is not straight forward. I think you need to
possibly deal with drawables (hopefully not, as this would never give me rgb
values) and color state lists. That's the reason I was looking for
documentation and sample uses in codesearch.google.com, but to no avail.
Cheers,
Mariano
