This document asks how to display the number value selected from a radio button in a radio group in a text view when a button is clicked. For example, if a radio group has options 1, 2, 3, 4 and the user selects 2, clicking a button would display the number 2 on screen. Visual examples are requested to explain how to retrieve and display the selected radio button number value.

how can i get the number values from one radio button selected from a radio group to show up
on screen in a textview.
for example if the radio group is like this
radiogroup1 values (1,2,3,4) and someone selects the 2nd option which is a number value, 2.
now they click a button and it displays onscreen the number they selected.
