My app loads new data like every four minutes, and if the pic is not there in time, too bad, you'll have it in the next round. What you can do is if the hashmap returns null, subsitute a default pic, which I gues you have to do because you'll probably have a recycled view which already contains a pic - but the wrong one.
It gets really weird when you have different views for the items in the listview, like when the user changes the layout, or you have different layouts in portrait mode and landscape, or all of the above. I chose to trade in options for better recycling of views. Another issue is, do you want to spend a lot of time at startup preparing for the listview so the scrolling is smooth, but the user has to wait a little longer, or do you want to display views quickly, at the cost of bumpy scrolling? At any rate, the simpler the UI, the better.
