Android Design Support Library: NavigationView source code

Question

I have searched several hours over the past few days for the complete source code of Android's design support library. I have found source code mirrored from the official Google repository:

https://github.com/android/platform_frameworks_support/tree/master/design

However, I have yet to find the source code for android.support.design.widget.NavigationView. The jar file for the library contains a NavigationView.class, but has no source attached.

How should I find the source of this class? Is the code possibly not released to the public?

Answer 1

If you download the Android 6.0 source code from your SDK Manager, you will find the source for NavigationView in:

$ANDROID_SDK/sources/android-23/android/support/design/widget

where $ANDROID_SDK is wherever you have installed the Android SDK.

My guess is that this matches the 23.0.0 version of the Design Support library. I do not know if patches (e.g., 23.0.1) will have their source show up here or not. And, for all I know, what is here in the source code is older than 23.0.0. Google's packaging of source code for the support libraries could use some love.
