Where can I find the implementation of APIs in Android?

Question

Is it possible to see the code on how the APIs in Android work?
Say, I want to see the implementation of method setContentView() or setStroke().
I am wondering if the implementation of these APIs are exposed.

Android is open source. You can find all the code from here: http://source.android.com/

If you use a Chrome-flavored browser, you can install the Android SDK Search extension, which:

Adds an ad search to the "omnibox" (a.k.a., address/search bar in Chrome), so ad AdapterView would take you right to the AdapterView documentation
Adds a "(view source)" link to the JavaDocs for each class that brings up the source code to that class

Basically, just install "Sources for Android SDK" from Android SDK Manager.
