You can simply add a focus listener on choicegroup , and handle your funtionality in focusgained() and focuslost() methods of focus listener...

If you are developing your application using the high level ui , then there are no methods to determine as such the choicegroup is fouccesd or not .
In this case you can have a default command set to the choicegroup such that the command will be added to the softkeys whenever
the choice group is foccussed
//
choiceGroup.setDefaultCommand(someCommand);
//

try out this it will solve your problem

Try using some UI toolkit like LWUIT - then you can do it with their choicegroup - by capturing the focus movement from 1 item to another....
