I found that if you do something like this it works almost identically
to the magic number method.
ListView android:id=@+id/your_list
android:layout_width=fill_parent
android:layout_height=wrap_content
/ListView
protected Dialog
Yes, that did work, thanks much.
What does that magic number represent?

Every view in Android has an id number assigned to it.
When you put android.R.id.button1 for example that is a constant that
defines the number 16908313.
The number 16908667 does not seem to have a constant defined for it in
the SDK.
This means that this number could be possibly be changed in a
Ya, so how did you conjure up 16908667?
In trying to debug this, I looked at the various android.R.id.* values
to see if I could see something else that makes sense, but didn't see
anything. If 16908667 is undocumented, where did you find it? By
spelunking through the source?
Thanks.

Excellent -- I have the same value for mlistView's mId in the
onPrepareDialog().
fwiw, I'm not casting to an AlertDialog, just the ListView:
ListView lv = (ListView) d.findViewById(16908667);
Pretty hacky, I'm not sure I want to ship this magic number, but
that's a ways off.

Sorry -- I was dealing with a headache when I wrote that... ;-)
It's actually good to hear the Android way doesn't include hacking
around IDs -- but at the same time, wish it was

That should work. There's a corresponding method on RadioGroup.
I have no idea if inflating from xml is the best way to instantiate a
view, it's just what popped in mind.
It's perfectly fine. You'll do
Ok, selecting through the radiogroup works. I was expecting a
setChecked method, and just missed checked.
Final version of onPrepareDialog():
RadioGroup rg = (RadioGroup) dialog.findViewById
(R.id.savecancelgroup);
rg.check(R.id.save);
Thanks for the help.
P.S. Using 16908667 was more fun...
