android UI external libraries?

I'm starting with android, and the app I'm developing is gonna need custom widgets look (glossy buttons, animated backgrounds etc.), I've googled for any external libraries to achieve this and did not find anything.

let me guess, the only way to开发者_运维问答 this is by painly extending base view classes and overriding onDraw etc. ?

You need to explore View Styles. You can customize almost any view element. You might not need any external library that extends and designs custom buttons.

I like this library quite a lot: https://github.com/cyrilmottier/GreenDroid

It includes:

• Action bar
• Quick action
• AsyncImageView and a lot of other things

It's easy to use and nice for quick developments.
