ImageView with Spinner

Question

I have a GridView displaying thumbnails using ImageViews. I am displaying a default image while the thumbnail images are being downloaded from the background(inspired from native applications) i.e. the getView() of my adapter class returns a default Bitmap first and then runs a background thread and replaces the default with actual later.

GridViews in iPhone application display a spinner (Animated GIF) instead of default image.

How can a similar thing be achieved in Android?
