Android-two threads changing the ui

Question

I have a UI with buttons. This thread takes input from the user and does a particular task. Now, I want the background of one button(generated randomly) to change periodically(say, every 30s), but i want the main thread to continue taking input. I m not able to interleave the threads in exactly this way. Any help would be appreciated. Thanks in advance.
