Hello there, I am trying to get my head around CursorLoaders and would appreciate some help.
I have a ListFragment which loads list data in a background thread via a CursorLoader/implementing the LoaderManager.LoaderCallbacks<Cursor> interfaces. The data in the list comes from a database via a ContentProvider and the ContentProvider manages calls to notifyChange() when the data is changed. I read on the Android Developers web site that when the data in the list is changed, the cursor becomes invalid and onLoaderReset() is called. Some functions other than the onLoadFinished() in my ListFragment use the cursor and also I have implemented a class derived from SimpleCursorAdapter which uses the cursor in getView(). If the cursor can be invalidated when the list data changes (which could happen in a separate service), should I be checking that the cursor is not null/invalid any time I use it in my class derived from SimpleCursorAdapter and my ListFragment? or is it safe to use?. Thank you for your help. -- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
