How can I setup the row id on every row for a ListView?

Question

Hello.

I'm developing an Android application.

How can I setup the row id for every item on a ListView? I don't want to use SimpleCursorAdapter. I have my owns objects, and I want to use them.

These objects have and ID and a NAME. The name will be displayed and the ID will be stored to retrieve it on onListItemClick(ListView parent, View v, int position, long id).

Any advice?

Thanks.

One simple solution would be to create a hash that maps names to ids:

Map<String, Integer> map = new HashMap<String, Integer>();
for(MyObject obj: objectsList) {
  map.put(obj.getName(), Integer.valueOf(obj.getId()));
}



String name = getListView().getItemAtPosition((int) id).toString();
int id = map.get(name).intValue();
