Radiobutton get not been unchecked!

Hi,
when I check a radiobutton, the radiobutton cannot been unchecked (the button stays checked even if you check another one), code looks like this:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.         private void addRadioGroup(ViewGroup view,final Question question){
  2.  
  3.                 RadioGroup group = new RadioGroup(this);
  4.  
  5.        
  6.  
  7.                 group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
  8.  
  9.                 {
  10.  
  11.                     public void onCheckedChanged(RadioGroup group, int checkedId)
  12.  
  13.                     {
  14.  
  15.                         for(Answer answer: question.shuffledAnswers){
  16.  
  17.                                 if(checkedId == answer.id){
  18.  
  19.                                         answer.state = true;
  20.  
  21.                                 }else{
  22.  
  23.                                         answer.state = false;
  24.  
  25.                                 }
  26.  
  27.                         }
  28.  
  29.                     }
  30.  
  31.                 });
  32.  
  33.                 for(Answer answer: question.shuffledAnswers){
  34.  
  35.                         RadioButton r = new RadioButton(this);
  36.  
  37.                        
  38.  
  39.                         r.setText( answer.answer);
  40.  
  41.                         r.setId(answer.id);
  42.  
  43.                        
  44.  
  45.                         //cannot been unchecked, also tried group.check(r.getId())???
  46.  
  47.                         if(answer.state){
  48.  
  49.                                 r.setChecked(answer.state);
  50.  
  51.                         }
  52.  
  53.                         group.addView(r);
  54.  
  55.                 }
  56.  
  57.                 view.addView(group);
  58.  
  59.         }
Parsed in 0.023 seconds, using GeSHi 1.0.8.4


It is described in the issue:
1772
but the issue is closed (I don't understand the answer)!?
Can someone point me in the right direction?
Thanks Mark

I think, my fault was to call setCkecked on the radiobutton, instead I have to call check with the radiobutton id on the radiogroup (and the missed call on clearcheck).
