Nothing seems to work... performances are even worse with a timer or delay
I cannot cache all the images because of memory consumption

Also adjust the opaqueBackground, don't set the image sources
inmediately but after a short timeout (so if you scroll down fast
skipping lets say 50 images you DON'T load 50 images before loading
the 51st), and use a contentCache loader with queueing
(http://corlan.org/2011/08/16/flex-mobile-development-caching-images-using-contentcache/)
P.S. you can use the ContentCache straight from MXML, not like the
sources in the link. Just declare it, set an ID and the rest of the
parameters, and set contentCache="{id}" in your itemRenderer.

Make sure you are using a bitmap cache and that the images are not
being scaled down on the device.

Hi,
in a mobile app I need to display a list of 200 images. On the list I
use a tileLayout with virtualLayout=true and a custom itemRenderer
that
only contains a Spark Image. On the set value method of the
itemrenderer
I change the source of the image with the path to the new bitmap.
It works, but performances are poor and the list doesn't scroll
well. On
iPad it's almost acceptable, but on Android I have to scroll row
by row
and wait until every image of the row is loaded.
Any suggestions to improve the situation?
Thanks
Gabriele
