Set selected index of an Android RadioGroup

Question

Is there a way to set the selected index of a RadioGroup in android, other than looping through the child radiobuttons and selecting checking the radio button at the selected in

Answer 1

Inside onBindViewHolder set the tag to Button Group

@Override
public void onBindViewHolder(final CustomViewHolder holder, final int position) {
   ...
   holder.ButtonGroup.setTag(position);
}

and in the ViewHolder

ButtonGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
        ...
        int id = radioGroup.getCheckedRadioButtonId();

        RadioButton radioButton = (RadioButton) radioGroup.findViewById(id);

        int clickedPos = (Integer) radioGroup.getTag();

        packageModelList.get(clickedPos).getPoll_quest()
    }
