Radio Group does not get focus in Android

Question

So, I have a form containing two components EditText and RadioGroup. When I click on one of the EditText fields, the keyboard pops up and I can correctly and everything is fine. UNTIL I click on one of the RadioButtons and it is clicked on the keyboard! And when I use the keyboard, it writes to the last focused EditText (Android 4.0), while on my Galaxy S2 (Android 2.3.6) it resets the application! I researched this problem and I found that this is a known issue in (Android 2.0), so what's wrong with what I'm doing?

I want to use the onFocusChange listener to test RadioGroup selection? Any ideas would be appreciated.
