There isn't really an interface exposed for getting the view objects from a ListView. These are constantly being switched out and stored for recycling as rows scroll in and out of the visible area.

However, you can do:

listView.getItemAtPosition(position);

to get the model (item) at a given position in the list. If you need to operate on information that the user changes in your list, then you would want to first save that information back to the underlying model individually when each component changes and then later aggregate over your underlying data objects to do your calculation.
