I want most, but not all, of my non-CheckBox Preferences to show their current values as summaries when displayed in a PreferenceActivity. I've implemented this by overriding onSharedPreferenceChanged() in my PreferenceActivity subclass. For each SharedPreferences instance passed in, onSharedPreferenceChanged() checks if the key is in a hard-coded list and if so sets the summary from the current value of the Preference.
It's a gross violation of OOP principles, but it works. What I'd rather do is somehow mark individual Preference subclasses in my xml file as desiring that behaviour. I've read how to create custom xml tags, but I can't figure out how to get at them from inside a PreferenceActivity. It seems the only access to a View's AttributeSet comes in its constructor, and I don't have access to that since I'm only overriding the Activity that contains these Views. I could accomplish the same thing by overriding every Preference subclass I use, adding nothing but an 'implements SomeEmptyInterface' statement. I'd then test inside onSharedPreferenceChanged() whether instances passed in implement that interface. But adding a simple xml attribute seems much cleaner. Is it possible?
