Steps

Source from Stephen Gray’s blog post:

1. Create a “RadioButtonGroup” MXML tag and give a id to it.
2. Assign the RadioButtons’ “groupName” attribute to point to the RadioButtonGroup at step 1 (remember to use “{}”)
   

   <mx:RadioButtonGroup id="myRadioButtonGroup" enabled="true" />

   <mx:RadioButton label="I like RadioButtons" groupName="{myRadioButtonGroup}" left="505" top="64" selected="true" value="true"/>

   <mx:RadioButton label="I don't like RadioButtons" groupName="{myRadioButtonGroup}" left="348" top="62" value="false"/>

3. Access the selected value by the RadioButtonGroup
   

   Alert.show(myRadioButtonGroup.selectedValue.toString());
