I once wrote a dialog with a single editText item which I disabled by
using a filterProc.  It would check for clicks on the item and keyDown
events; if it saw any, it would change the itemHit to zero, and return
true, i.e., lie and say "Yes, I've handled this event."

With a bit of work, this technique could (I think :) be extended to
work with multiple editText items, but I haven't had to do this yet,
so I'm not quite sure how.  If someone knows an elegant solution,
I'd like to know too!
