This is a side-effect of view recycling... You have to create some sort of caching mechanism. When your adapter's getVIew() method you then consult the cache and set the checkbox state accordingly.
It is a bit of a pain, but as you said in your post... if you don't use view recycling then the performance suffers. This caching mechanism is a small price to pay to gain the extra performance benefits of view recycling.
