I was asking myself the same question. Doing a searches on Google, I found some good info. First of all you should start by reading the documentation presented by Google Android:

• http://developer.android.com/guide/topics/ui/custom-components.html

After that, for general tutorials of a view that extends the android.view.View class, these seem to be good examples:

• http://www.androidcompetencycenter.com/2009/08/creatingcustomviews/
• http://www.skill-guru.com/blog/2011/01/20/creating-a-custom-widgets-in-android/

As for using the android.view.ViewGroup, there seems to be already some posts on the subject:

• How to use viewGroup in android
• custom ViewGroup example?
• Can anyone give a good example of a Custom ViewGroup containing a Custom View with measure and layout examples? (In Java)
