A surface is a buffer. A Canvas holds the drawing.
Views are not attached to the Canvas nor the Surface. The window is tied to a Surface and the ViewRoot asks the Surface for a Canvas that is then used by the Views to draw onto.
For a detailled anwser, you can read this whole discussion, really interesting.
