I think SimpleCursorAdapter can handle that without subclassing via setViewBinder(), though I haven't experimented with this yet. > * Hand populating the ListView by reading in the Provider data and > populating an array in OnCreate.

I think you're supposed to call setViewBinder(), not override getViewBinder(). > Could someone give me at least a hint as to how I can create a custom > CursorAdaptor which binds to two fields instead of just one like > SimpleCursorAdapter? There must be some easy way ???? Override bindView() and bind it yourself, if needed. bindView() will receive a Cursor (pointing at the right position in your data set) and the View to bind it to. You can call super.bindView() to allow SimpleCursorAdapter to do the basics, then use findViewById() on the row View to find your ImageView and set an appropriate resource on it. Here is a free excerpt from one of my books that touches on some of this, though in the context of an ArrayAdapter, since by this point in the book I haven't introduced Cursors yet: http://commonsware.com/Android/excerpt.pdf -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android 2.2 Programming Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
