Radio Button in android application

A radio button is a two-state button that can be either checked or unchecked. When the radio button is unchecked, the user can press or click it to check it.

Radio buttons are normally used together in a RadioGroup. When several radio buttons live inside a radio group, checking one radio button unchecks all the others.
