"Separators" in ListView

Question

I have an ArrayAdapter which is hooked up to my ListView. I really like the "separators" feature in the Evernote Android application, where they separate items using a datestamp:

I assume what they're doing is having a view immediately above the list which is set to the value of the current separator, as you can see in the screenshots. (As you scroll past a separator, the text at the top is set to the value of the current separator, ie "January 2011") How would I actually insert the separators into my ListView?

Answer 1

A separator is simply a disabled list item, just have your Adapter return the separator where it should be. Seems like SectionIndexer could help.
