Answer 1

One way you can but I don't know it's perfect or not.

track the position id of the listview on which the radio button was checked now when you click on the another radio button then implement the setOnCheckedChangeListener(listener) and check the position which was already check and uncheck that radiobutton.

You can store the status of radio button into the custom model(Model which contains the controls like textview, imageview, radiobutton etc for listview single row) which was added into the listview

check this article for using model and handle the component into the listview in this given an example of checkbox

Update

I think you can get tag like this way

((View)((ViewGroup)listview.getItemAtPosition(0)).getTag()).getTag();
or
((Button)l.getItemAtPosition(0)).getTag();

update 2

suppose this is your adapter and arraylist object

private List list_model = new ArrayList();

private ArrayAdapter modelAdapter;

you Model class look like this

private class Model{
    private String text1 = "";
    private boolean isChecked   = false;

    public Model(String text1){
        this.text1 = text1;
        isChecked = false;
    }
}

your viewholder

private static class ViewHolder{
    TextView textView;
        RadioButton radioBtn;
}

pass the listmodel to this CustomAdapter class in constructor

private List list;
private Context context;

public CustomAdapter(Context context, List list){
    super(context,R.layout.list_layout,list);
    this.list = list;
    this.context = context;
}

now in getView()

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = null;

    if(convertView == null){
        LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inflater.inflate(R.layout.gcalendar_list_layout, null);
        final ViewHolder viewHolder = new ViewHolder();
        viewHolder.textView = (TextView) view.findViewById(R.id.text1);
        viewHolder.radioBtn = (RadioButton) view.findViewById(R.id.radioBtn);
        viewHolder.radioBtn.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                Model element = (Model) viewHolder.checkBox.getTag();
                element.isChecked = buttonView.isChecked();
                boolean isChecked = true;
                for(int i=0;i
