I have what seems like a very basic question: how can I maintain the sorted state of a ListView as new items are added to the list?
I have a ListView that is populated from a database. Specifically, I query my database, create an ArrayList of items, and use a custom ArrayAdapter<MyType> as the adapter of the ListView. Now, I understand that I can use ORDER BY in my db query when initially populating the list. But what about when new items are inserted? I also understand that I can call the .sort() method on the ArrayAdapter<...> passing in a Comparator... But does this mean that I have to call sort every time a new object is added to my database (and thus, my ListView is updated)? That doesn't seem right. The answer here (http://stackoverflow.com/questions/3496137/how-to- update-a-cursoradapter-tied-to-listview-when-number-of-items-changes) by JRL seems to indicate that using a CursorAdapter doesn't really solve the problem either. I have searched around but not found an answer to this question. All I've found is help on how to sort in the first place, for example: http://groups.google.com/group/android-developers/browse_thread/thread/b21831ed773bf1fa. What I need is something like a setSorter(...) method that's available on certain Eclipse Viewers. Does something like this exist?
