There is no method 'getView' on a ListView class. And i expect i wouldn't
return a number....
However, you do define a *static *field called *listItems*. Do you update
the *listItems *field directly without notifying the your *BaseAdapter*? If
so, this could be the problem. Notify the *BaseAdapter *by calling
'notifyDataSetChanged()' on it after you make the appropriate changes to
its data (*listItems*).
Note that you should not make this field (*listItems*) a *static*/class
field. Just make it a regular/instance field, fill it with data and send
this to your BaseAdapter and let your BaseAdapter handle it.
