Hi, in this video, I’ll show you step-by-step, how to use RadioButton and RadioGroup in Android Studio.
You’ll be able to design an XML layout that consists of a RadioGroup containing five radio buttons and two other normal buttons to clear the selection and 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.
