What's the purpose of item-id's in Android ListView Adapter?

Question

(Not specific to ListView, but to Adapter).

I keep implementing this when I subclass BaseAdapter:

    @Override
    public long getItemId(int positio         


        

Answer 1

If you subclass ArrayAdapter instead, you may not have to implement that method.

Mostly I find that method useful to determine what row was clicked during onClick events, and use that ID as part of the Intent extras passed to the next activity.
