I've created an ArrayAdapter<Integer> for a ListView as such:
aa = new ArrayAdapter<Integer>(
this,
R.layout.centered_list,
new Integer[] {0,1,2});
(very similarly, anyway)
If I try using aa.add(3) or aa.insert(3,3), I get an
UnsupportedOperationException. Here's the full output:

The only problem I can think of is that it is an "Array"Adapter,
rather than another form of container, but I assumed that was only
because you input an array. Why even have add, insert, or remove
methods?
Does anyone else get this exception? Does anyone have a fix?
