i'm using table layout arrange buttons. long use same font labels aligned in each row. for buttons i'd use icons custom ttf font. when use such icon, button placed higher, so: (this image scaled make the problem more evident.) i took measurements - buttons appear of same height, regardless of used font. why buttons not aligned properly? have suggestion them aligned? thanks. following commonsware's advice (thanks quick replies!), tried this: final linearlayout.layoutparams layoutparams = new linearlayout.layoutparams(viewgroup.layoutparams.match_parent, viewgroup.layoutparams.wrap_content); layoutparams.gravity = gravity.center_vertical; row.setlayoutparams(layoutparams); this did not work. try base alignment comment next. add following attribute tablerow : android:baselinealigned="false" by default, button labels' base lines vertically aligned causes offset experience.

want center mkmapview on point n-pixels below given pin ( which may or may not visible in current maprect ). i've been trying solve using various plays -(cllocationcoordinate2d)convertpoint:(cgpoint)point tocoordinatefromview:(uiview *)view no success. anyone been down road ( no pun intended )? the easiest technique shift map down, 40% coordinate be, taking advantage of span of region of mkmapview . if don't need actual pixels, need move down cllocationcoordinate2d in question near top of map (say 10% away top): cllocationcoordinate2d center = coordinate; center.latitude -= self.mapview.region.span.latitudedelta * 0.40; [self.mapview setcentercoordinate:center animated:yes]; if want account rotation , pitch of camera, above technique may not adequate. in case, could: identify position in view want shift user location; convert cllocation ; calculate distance of current user location new desired location; move camera distance in direction 180°...
