Have you considered using a footer instead of placing the last item inside the ListView?

What you do is, before you set the adapter of the ListView, you inflate a footer layout (or perhaps just a TextView, if that's all you need). Store a reference to it, and then add it to the ListView:

TextView myFooter = new TextView( context );
myListView.addFooterView( myFooter );

Then when you add items to the list or when the calculation needs to occur, you just calculate and set the text of myFooter.

myFooter.setText( myCalculatedValue );

Setting the text of the footer must ofcourse happen on the UI-thread so if you use a background thread or a AsyncTask to add to your listview, be sure you update stuff the right place.
