Answer 1

Here you go.

I have set up 4 radio buttons for the user to click.

You must have defined them in radioGroup,right?

Then you can iterate in RadioGroup to set names to RadioButton
or you can get RadioButton by index and set name to it.

RadioGroup radioGroup = (RadioGroup)findViewById(R.id.group);

    for (int i = 0; i < radioGroup .getChildCount(); i++) {
            ((RadioButton) radioGroup.getChildAt(i)).setText(String.valueOf(i));
        }
