question: static public void assertTopAligned ( View first , View second , int margin ) { int [ ] xy = new int [ 2 ] ; first . getLocationOnScreen ( xy ) ; int firstTop = xy [ 1 ] ; second . getLocationOnScreen ( xy ) ; int secondTop = xy [ 1 ] ; assertEquals ( "views are not top aligned" , Math . abs ( firstTop - secondTop ) , margin ) ; }
target:  Assert that two views are top aligned, that is that their top edges are on the same y location, with respect to the specified margin.
