Not seeing calls to the finalizers is not an indication your ListViews are not being GC'd. Just by having an overriden finalize() method, you are keeping the objects longer in memory (because they are enqueued for finalization.) Instead of relying on finalizers, use a heap dump from DDMS and inspect it in MAT (Memory Analyzer Tool, an Eclipse plugin.)
