Finding Android source code

Are the Android APIs open sou开发者_C百科rce? If so, I want to see how they implemented the smoothscroll method for the ListView object (this is implemented in API level 8, but I want to build against an earlier API level). How would I go about finding this?

Yes, it's open source, and http://source.android.com/ has all the information on how to download and browse the source.

This is what you want: ListView source code.
