Hi there! I had to write a duplicate of the "image viewer" last week. And I couldn't find the "Image View" source code. For those wondering why I didn't use the intents, it's just because my images are dynamically loaded from the web...
Since I did it for my company, I can't publish the source code. But I can give you some tips. First of all, you should read this: http://groups.google.com/group/android-developers/browse_thread/thread/13fafedb71ccc296/0c0bc0830a20ee82 The whole tip is about using an ImageView with a Matrix. The Matrix enables you to translate / scale / rotate the image, so basically, zooming is just a question of scale + translate (to zoom to the center: when you scale, the fix point is the top left corner, so you need some translates so that the center is the fix point). Good luck with that.
