I think my shuffling and your memory errors are related. My understanding at this point is the data being displayed in a view and the view itself really need to be separated. Recycled views are simply "other views of this type" - so using the view to hold/load its own content might result in sever

I had similar issues. I managed to fix the performance of the list- view, but i ran into memory issues. My app downloads images from Smugmug, images that are 'front-page' images of galleries/albums. First, my app needed to get the information about the album, to get the image-id of the album's fr

Thanks gesh - as suggested the problem was related to recycling. Preformance is pretty good now, sadly my images keep shuffling but given your recent input this should be easy to fix. On Mar 15, 10:03 pm, Gesh wrote: > > I'm currently using the ImageAdapter from the Hello GridView sample. > > Bu

Like it's been mentioned previously, make sure you are recycling the convertView passed to the getView() method. Also make sure that you are not drawing images that are scaled at drawing time. On Sat, Mar 14, 2009 at 11:22 PM, ifuller1 wrote: > > Hi Gesh, > > Thanks for the response. I'll certai

p.s. when running the debugger I don't appear to be using anything like 16mb of the allowed heap space... wonder if it's something else - if I don't have any luck I'll post my (likely very poor) code up here. Thanks again. On Mar 14, 11:38 pm, Gesh wrote: > hi, > > I have written 2 connected ap

Hi Gesh, Thanks for the response. I'll certainly give the bitmap factory a go. I'm currently using the ImageAdapter from the Hello GridView sample. But loading the images from the web rather than using resources. The problem is immediate, in that the performance doesn't degrade after re- visits t

hi, I have written 2 connected apps with some image content pulled from the web and must say if you handle your resources right it shouldn't be a problem at all. Do you use your own Adapter for the GridView or do you use some of the already available ones in the SDK? If you use your own you shou
