I have four buttons arranged in a 2x2 TableLayout. These buttons each have an image on the left and some text. The buttons display fine in the emulator for 1.5, and for 2.
I also ran into the same problem on 1.6 and 2.1 but not on 1.5 nor 2.2.
I use LineraLayout and set its weight instead and skip the problem using TableLayout.
