Yeah, just ran a quick test and setting cancelable to false stills lets the dialog be dismissed by a button press. Weird. This definitely feels ass-backwards.
Well, the last thing I can think of is adding your own layout with an OK and cancel button with Dialog.setView() and handle the clicking on THOSE the way you wanted to. That should definitely work. And it might be less work than a full-blown wrapper. Good luck! ------------------------------------------------------------------------------------------------- TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking On Fri, Nov 20, 2009 at 2:24 PM, Jason Proctor < [email protected]> wrote: > according to the docs, setCancelable() determines whether the "back" > key cancels the dialog. > > it's not so much the cancel behaviour as the ok behaviour. if the > dialog didn't auto-dismiss on an OK click, then things would work a > lot easier. > > well, i'm just going to write a wrapper class that does all this dumb > stuff and calls out to custom validator and acceptor listeners to do > the necessary. it's a bit odd that Android has listeners up the wazoo > but Dialog doesn't quite fit in. > > > > >What if you call setCancelable(false) on the dialog?
