This actually isn't an answer to the question. I wanted to know if there was a way to do this without reimplementing all the the work done in addPreferencesFromResource in Java and Layouts.
Android encourages you to use the XML PreferencesScreen framework so that you don't have to reimplement extensive preference screens in Java. This makes preference screens retain look and feel between applications. Furthermore, Android (or a device manufacturer, particularly if the device is unusual form factor) can tweak the look and feel of such screens and such changes would be effective across most Android applications. It appears to me, that if you don't want users to have to click-through to see the current value of a ListPreference, you can't use this wonderful framework. I'd like to know if I can use the PreferencesScreen for this commonly needed request. I already knew I could implement it from scratch if I wanted to, but that not only seems wasteful, it completely misses the advantages of using PreferencesScreen in the first place. P. V.
