I have used the technique, but not in code I'm allowed to share. I do
need to more formally write this up at some point, but I do not have
anything immediately handy.
I've done the same in my apps for ListView (whether they be in
ListActivity or in a plain Activity) with good success.
I use the java.util.concurrent's ExecutorService to obtain images:
1. Your getView(..) (or bindView/newView/etc) needs to assign an image/
thumbnail (bitmap) to an ImageView.
Here is a code-snippet. I may not compile, but i think you'll get the
idea :-)
[code]
ExecutorService EXECUTOR = Executors.newFixedThreadPool(3); // max 3
worker threads.
...
public View getView(final AbsListView listView, View convertView, int
pos, long id) {
...
...
final String imgUrl
Thanks for explaining.
Right now I'm using the efficient list method used on the ApiDemos so when
the user scrolls it will refreshes the images that didn't load before. But
if you don't move anything, even if the image is downloaded it won't redraw
in the imageview.
I will start reading about
I think that's what I'm looking for. Can't wait to give it a try after work.
Although, I have another thread in my main Activity downloading all
pictures.
Thanks, I will give it a try.

ListView does not use scrollY. There's no need to save the scroll
anyway because ListView does it for you.

But when I refresh the listview with setlistadapter(listadapter) it returns
to the top.

Don't refresh it with setListAdapter! Just modify the content of the adapter
instead.
