You need to ask what you want to get help with, and what you have tried, at least give some effort if you want to get help. — Ludwig S, Jan 12 '16 at 07:22
@AnilBhat what you are passing in `createOptionsView ` . specifically value for the `optionNo` parameter ? — user1140237, Jan 12 '16 at 07:24

Try this code:

for(int i=0; i<numberOfOptions; i++){
            rb[i]  = new RadioButton(getContext());

            radioGroup.addView(rb[i]);

        }

You try rb[i] = new RadioButton(getContext()) and "optionNo" diffirence "i"
