Q:

How I can change the Background in runtime in Android?

I want to make a simple program with 2 Radiobutton (rd1 and rd2), what can change background to picture s1, or s2, depend on what was selected. How I can make it? I tried background.setBackground (background is my RadioGroup's name), but it didn't work.
