In my application, I have a ListView with a SimpleCursorAdapter, and using setViewBinder to format each row of data accordingly. It works, but I noticed while debugging that as I scroll up and down my list, the binder's setViewValue() function is called for each row as it is shown on the screen, and basically reformats the rows over and over again as long as I scroll up and down. So if I have 20 items in my list, setViewValue() is called 20 times as I scroll from top to bottom. If I scroll back up, its called again as each row is shown. If I sit there and just keep scrolling my list, a lot of garbage collection happens as a result.
I'm looking for ways to optimize this to hopefully reduce the need to re-format each row as it is displayed. If it's already been formatted with setViewValue(), is there a way I can skip doing it again as I scroll back up? Am I missing something here? I came across a comment from Romain Guy on a "Fancy ListViews" tutorial (http://androidguys.com/?p=635) regarding the use of convertView which sounds like it would optimize things. Unfortunately, I can't find a way to apply the logic to my application using the SimpleCursorAdapter. Am I on the right track? Or is this "good enough" to accept the frequent setViewValue() calls when scrolling? I'm still leaning, but I'd like to at least learn the right way from the start! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
