Android theme customization

I am working on theme-ing my android app. After I went through 'Styles and Themes' in Android SDK and this article, I am still left with one question.

Simply put, how can I use android:textSize to be 14 dip for one TextView, while 18 dip for another TextView, inside a Theme?

I know how to do this with styles. I can define two different styles and make the two different TextViews to use those styles.

What I find di开发者_如何学Cfficult is how to do this with Theme. A theme lets me define let's say android:textSize, but then it's applicable to all the TextView s in all the layouts of the Activity.

Any idea how to do that?

Thanks.

You can also do it with creating a style, for instance, "subtext", and apply the subtext style to multiple elements. Check out the links I posted in this question.
