I wrote a class to handle this, as it seems to be a recurring need in my various projects:
https://github.com/koush/UrlImageViewHelper
UrlImageViewHelper will fill an
ImageView with an image that is found
at a URL.
The sample will do a Google Image
Search and load/show the results
asynchronously.
UrlImageViewHelper will automatically
download, save, and cache all the
image urls the BitmapDrawables.
Duplicate urls will not be loaded into
memory twice. Bitmap memory is managed
by using a weak reference hash table,
so as soon as the image is no longer
used by you, it will be garbage
collected automatically.
