AFAIK, if you override getView() in any adapter class, the resource ID
you provide in the constructor is ignored. That doesn't prevent you from
using ViewInflate with that resource ID, or any other, in your own
getView() implementation.

Don't call super.getView(). You want to override it completely and do
not want the superclass' implementation.
With regards to the IllegalStateException, without a trace or something,
I can't comment. But that doesn't matter -- I'd recommend tossing out
all that code and going with:

Which is why you shouldn't be using it.
Use a graphics program to make yourself your dots, make yourself a
layout with an ImageView (for the dot) and TextView inside a
LinearLayout or something, and if convertView is null in your getView()
implementation use ViewInflate in order to turn the XML into the proper
View object. Then fill in the View (either the one you created or
convertView) with the data.
