Android: how to use SectionIndexer

I am trying to find a way to use SectionIndexer, instead of AlphabetIndexer. What I am interested to do is to have elements of a string arrays on the section headers instead of alphabets. I have not been able to find any sample code using section indexer.

Here is a sample code for AlphabetIndexer:

private AlphabetIndexer indexer;
indexer = new AlphabetIndexer(c, c.getColumnIndexOrThrow(
   DbHelper.COUNTRIES_NAME),"ABCDEFGHIJKLMNOPQRSTUVWXYZ");

Is it possible to pass a stringArray instead of "ABCDEFGHIJKLMNOPQRSTUVWXYZ" to the AlphabetIndexer so I can for example instead of "A", "B", ..."Z" as header have "Book", "Food", ...on the headers?

If not what is the best way to do that? Any reference to a sample code that uses SectionIndexer instead of AlphabetIndexer would be helpful as well.

Thanks for the help. TJ
