Class Overview

A RadioButton is a two states item (checked, unchecked). However, unlike CheckBox, items cannot be unselected by the user once checked. RadioButtons are normally used into RadioGroup. In that case, their state are linked and only one item can be checked at a time.

Note that a RadioButton is not necessarily part of a RadioGroup: it can be added directly to a layout.

Cross Platform Considerations

In Android, a RadioButton is a android.widget.RadioButton. It is composed of an image, for which the visual aspect changes if the button is checked or unchecked, and a text at the right of the image.

In iOS, a RadioButton is a UITableViewCell inside a UITableViewController. A check mark is drawn at the right of the button text to indicate if the item is checked or not. The mark is inside the cell.
