This code wasn't working for me in Android Studio 1.1 and I think I know why.

According to Google in their UI Guide here: http://developer.android.com/guide/topics/ui/themes.html

XML styles should look like this: style="@style/CodeFont" without the namespace "android:". If you add the namespace, it will show up correctly in the layout preview, but it won't compile.

Hey Angel!

Yes, this is correct! We don't use the android: prefix for styles (I don't know why but, hey ho) so, this would be what's causing the issue. And that's also pretty strange that it comes up in the preview with it as, it shouldn't actually work!

Edit: Actually after thinking about it, it does make sense. All values don't actually use the android: prefix because, they're not seen as "Android objects" really, I guess it's just things like the actual text itself (Not the storing of the text though) that's part of Android. So, basically the values we store don't have the android: prefix.

Oh, by the way! I forgot to say this, but the reason I posted this was because in the second fill-in-the-blank question of the "Introducing Styles" quiz, it definitely includes the namespace, so that should probably be fixed. Unless I'm missing something.

Yep! You're right! I just took a look at this quiz and it does indeed use the wrong attribute.

Ben Jakuben perhaps you could take a look at this at some point? Rather than android:style="" on the 2nd quiz question, it should just be style="" :)
