i know view means components of user interface(source: same link) , can buttons. have hierarchy link: http://imgur.com/yivkno5

by definition @ top, topmost view image view(which @ top of screen) or relative layout(that contains everything)

rootview view contains other views. means that, in case, relative layout root view.
