I followed your suggestion and created my own version of ArrayAdapter, overriding getView().
Everything works, however, with some logging, I'm finding that getView() is not called n times (n=number of items in list), but 2n+1 times (getView() is called 3 times for the first list item, two times apiece for the rest). This significantly increases my application startup time as I call ViewInflate everytime during getView(). Is this normal (should ArrayAdapter really be calling getView() more than n times)? And if so, any suggestions on how to optimize?
