ContentProviders are somewhat more abstract than SQL... You could have a special URI that means "increment this item's view count", e.g.:
authority/item/# - for operations on the entire item authority/item/#/viewcount - updating would increment the view count by one It might also be possible with a batch operation, but I haven't used those and can't say if there is support for an "N+1" type backreference. 16.04.2011 20:59 пользователь "Paul" <[email protected]> написал: > I have an app that as the user opens 'things' from the ListView, I > want to update their view count as they are opened.
