In this video we will learn, how to use RadioButtons and RadioGroups. We will react to clicks and display our selection in a Toast message and in a TextView. Radio Groups will make sure, that we can select only one Radio Button at a time. RadioButtons are helpful to implement multiple choice features into your app. You'll be able to design an XML layout that consists of a RadioGroup containing three radio buttons and one another normal button to get the id of the current selected RadioButton in this group. When the Submit button is clicked, a Toast message is displayed based on which radio button is currently selected. The clear button clears the selection. I'll also show you how to register a callback on RadioGroup and get a corresponding Toast message when we click a radio button for the first time or when the checked radio button changes in this group.
