Hello, I´ve been searching on the web and here for information but couldn´t find anything related to this problem so I hope you can help me. I´m retrieving information from 2 diferent content providers that are related. Information from one content provider (songs list) should define the rules to filter another group of info (albums).
I´m trying to create an expandablelistview where only the albums which have mp3 files would be listed as headers, and the mp3 songs would be in the second level list. At first I tried to figure out a way of implementing ContentProvider searches that would allow me to recover only the required data but I couldn´t find a way to do it (use group by, relate both contentproviders in the same query, ...). Then I tried to retrieve the info and filter programatically but the Cursor class doesn't have methods to remove or filter information. After I tried to figure out a way to implement the rule in a CursorAdapter but while I can customize the information handling, I couln´t find a way of blocking some retrieved Cursor "lines" so I could display only albums with at least one mp3 file. Please, throw some light in here. How can I archive this result? Thanks, Gabriel Simões -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
