Thank you for your answer. You're right. @+xxxx does mean make new id. I think It will be not working if I use @+id/android:list instread of @id/android:list. \ But, It is also working. According to that document, ListActivity may generate some error when it use @+id/android:list because we not use existed id but add new id.
I don't know why it is working. ;( On 7월17일, 오전8시41분, DanH <[email protected]> wrote: > In a nutshell, "@id/xxx" means use that pre-existing ID#.
