I am using addPreferencesFromResource to display a list of preferences with the facility to edit them with a popup. Is there any way I can check the entry and show a hint for formatting whilst the individaul edit popup is still in focus? Is there some way to specify a format in the PreferenceScreen xml? For starters I want to ensure a time is entered as "h:mm" but not wait until I exit the screen to verify/message. Thanks Ron
