How do I fade the background smoothly?

Hi all, I've been playing with Android development for a couple of weeks, on and off... and I'm trying to get the background to fade from one color to another.

I can use the following to change it in one step, and it works (note, 'screen' is the name of the LinearLayout):

  1. int p = 0x00ff00;
  2. screen.setBackgroundColor(0xff000000 + p);

but if I try the following I get nothing (the 0.01 inc is to implement a basic ugly delay to see if I could see the change - I do need to have this fade happen slowly and smoothly, so some kind of delay is needed at each step in the loop):

  1. for (int i = 0; i < 65535; i += 0.01) {
  2.     screen.setBackgroundColor(0xff000000 + i);
  3. }

Am I missing something? I'm assuming that its thread-related and that the thread is blocking the GUI while the loop is being done... but thats just a guess. I understand the basic concept of threads, but I've done no programming with them.
