styleable

I would like to have entity (control or property) which has different states, which are possible to be colored by CSS. For example, regard TextField, which can contain two sort of values, normal and erroneous. Once it contain erroneous value, it should be displayed "red".

Browsing attr.xml (the Android source for the standard attributes), I discovered that you can do things like: <!-- The most prominent text color. --> <attr name="textColorPrimary" format="reference|color" /> The format attribute can evidently be set to a combination of values. Presumably the format
