[android-developers] Re: Extracting colors from Themes?
Do you need to be doing this programatically? You could always take a
screenshot of your phone [either using DDMS on a non-rooted device or
the PicMe app on a rooted device] and then grab the colors using
Photoshop or any image editing software. Another option, again not
programmatic, would be to download the Android source [or you can
browse it online in the Git repo] and find the declarations for those
colors.

[android-developers] Re: Extracting colors from Themes?
Mariano-
Well if the colors are publicly accessible you could access them
directly [find out the color resource identifiers by digging through
the source for the system theme/style xml files.. available in the Git
repo], something like: @android:color/resourceid .. This will allow
you to use the same colors a theme is using [providing those color
resources are public.. I've never tried this].

Re: [android-developers] Re: Extracting colors from Themes?
Hey Pat.
Thanks for your chipping in.
No, I could also hardcode the colors and that is what it seems I will have
to do. In my particular case it won't make much difference at the moment.
For now I just need two values and they correspond to the light and dark.
But for the future my needs will grow and it is also not so much fun to
maintain a shadow theme administration on the side.
I would have preferred to be a model citizen on the Android platform and use
the themes. Hardcoding might be the quickest solution, but would fail if I
want to use platform properties that are overwritten by vendor themes.
To give you an example. On a stock Android device you'll see an orange
background behind a selected list item, on an HTC sense device it would be
green instead.
Also as themes look so central to me, I was kind of hoping that I just
missed the relevant documentation and that somebody else would point me to
RTFM ;-)

Re: [android-developers] Re: Extracting colors from Themes?
Hey Nick,
that's the thing. It's not that easy.
Checkout what I wrote in my initial post:
@android:color/background_dark
@android:color/primary_text_dark
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
