Yes, one query to get the categories (cities), then, once a city is selected, another query to get the addresses. Or you could preload the entire data set and do your own filtering in memory - depending on how large the data set is.
Take a look at ListPreference source code - if you wanted the list selection to use an alert dialog popup. Or you could use a PreferenceCategory and insert Prefrerence entries representing cities - if you wanted to show all the cities within the same screen. -- Kostya 2011/6/10 Andrei <entre...@gmail.com> > Hi all.
