Questions tagged [android-radiobutton]

Use for the android.widget.RadioButton element. Radio buttons are normally used together in a RadioGroup.

Radio buttons allow the user to select one option from a set. You should use radio buttons for optional sets that are mutually exclusive if you think that the user needs to see all available options side-by-side.

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.
