Hi Mark. I've taken a look at this, and put together a quick sample based on your demo.
It seems to me that you must have your list content already separated before adding them to the ListView. So, you add one Array, then you add a different View, then you add another Array. I can probably find a way to sort my data in this way, although I was hoping to add the view on the fly. My data is currently returned as one long List, and I don't know in advance where these separator views are going to go. I need to study the contents of my data as it's added to the View, and say "Ah, here's some condition, add a separator view here". Does that make sense, and can this be done? Thanks.
