In this tutorial, I show you how to use Radio button in Android using example.
RadioButton is a two-states button that can be either checked or unchecked.
Radio button generally works with RadioGroup.
Radio group can hold multiple RadioButtons, however only one can be selected at any point of time.
Once a radio button is checked by user it cannot be unchecked again by pressing the same button.
It automatically gets unchecked, where any other button on the same RadioGroup is selected.
