How to create a our own custom view in android

I want to create my own view like how android provide the Gallery and the GridView .

My requirement is something like i should display my icons/images(take any widgets) in the circular view.

I am confused how to do it?

Either to go with new view or i can solve it by using animation or something else.

Can any one tell me how to start with?

I assume to create a new view we should code at framework layer... Is it right?

Or I can get it done in application layer开发者_运维技巧 only?
