Question

I have created a custom Adapter called: ContactsAdapter which inherits from BaseAdapter and implements ISectionIndexer.

Is it possible to implement an AlphabetIndexer on the custom adapter without making use of a ICursor? Reason being, the adapter makes use of a List<T> to stores all the items.

Many thanks in advance!

Answer 1

Short answer; yes you can do it without making use of ICursor. Basically you implement the interface ISectionIndexer on your BaseAdapter<T>

ISectionIndexer implementation consists of the following methods:

    public int GetPositionForSection(int section)
    {
        ...
    }

    public int GetSectionForPosition(int position)
    {
        ...
    }

    public Java.Lang.Object[] GetSections()
    {
        ...
    }

Kind regards,
