Hi Kostya Ok. Let me explain further. I am changing button state by doing button.setEnabled(true or false) but, the state that the button is currently in, won't show up on the screen unless I touch the screen. That is where I mentioned about button's focus.
So, even though the button is getting disabled through my program by calling button.setEnabled(false), on the screen, I still see the button as active and only when I touch the screen, the button is seen to be in the inactive state (disabled state with grey color). I hope that solves your confusion?
