Get the array of RadioButtons in a RadioGroup in Android

Question

Is there any way of getting an array (or a collection) of the RadioButtons in an Android RadioGroup? I would like to add individual listeners to radio buttons but I don't see any obvious way of iterating over them.

Answer 1

this should do the trick:

        int count = radioGroup.getChildCount();
        ArrayList<RadioButton> listOfRadioButtons = new ArrayList<RadioButton>();
        for (int i=0;i<count;i++) {
            View o = radioGroup.getChildAt(i);
            if (o instanceof RadioButton) {
                listOfRadioButtons.add((RadioButton)o);
            }
        }
        Log.d(TAG,"you have "+listOfRadioButtons.size()+" radio buttons");
