You need to modify your LazyAdapter code to return right layout for each row, depending on any criteria you want. ListView simply uses view given by adapter, so it is nothing special to have each row layouted differently. Please note that to make it work correctly you need to implement getItemViewType() and getViewTypeCount() as well.
