    inside the baseAdapter, for the getView() method , instead of getting the item in the data in index "position" , use the opposite , meaning : numberOfItems minus the position .

    as for showing the number of items , that's also inside the baseAdapter : set the value returned by getCount() to be the one you wish it to be (20 in your example,though 80-100 implies that it should be 21 ) .

    btw, it seems you are a starter in the case of listView . may i suggest watching this video: http://www.youtube.com/watch?v=wDBM6wVEO70

    also check the api-demos provided by the sdk manager . they have plenty of examples there.
