ArrayAdapter does not convert the array you hand it into an ArrayList. Since you cannot remove from a Java array, ArrayAdapter cannot remove it, either. My guess is that the array-versus-ArrayList thing is an optimization for short static lists, as arrays should take less memory and are probably faster. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Looking for Android opportunities? http://wiki.andmob.org/hado --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
