This solution uses nested weights, which reduce rendering performance; the amount of performance degrade will depend on the host devices capabilities, but it really isn't noticeable unless the layout is somehow forced to refresh with a quick interval. Seeing as there aren't any static values associated with widths or heights, this layout will shrink and grow as necessary on any screen, this is thanks to using match_parent (fill_parent is as good as deprecated) and RelativeLayout root element, and a child vertically oriented LinearLayout replacing your TableLayout, with several nested LinearLayout elements replacing your rows.
