How are styles and themes applied in Android?

Question

Android

How is the drawing of different views / viewgroups at a low level? It is clear that in the onDraw(Canvas) method, but how are the themes/styles applied? How is the animation shown? Where can I read about the Android Framework device, except from the source? I will be happy with links.

Answer 1

Well, if you look at the textView sources, it shows that values ​​​​come into attrs, then they are parsed and the view is drawn based on them, as far as I figured it out.
