I'm still stuck on this problem. I tried to solve it by making the
whole activity dynamic. But still the button is positioned at top
left.
I can't see why
ok.layout(k.getLeft(), k.getTop(), k.getRight(),k.getBottom());
isn't repositioning the button, even if it shows the right Values on
LogCat.
I really need some help on that !
