How to make a Preference not save to SharedPreferences?

I am re-using ListPreference for a setti开发者_如何学编程ng which I store only in the database. How can I prevent it from storing/persisting any data to the preference file?

Subclass it, override shouldPersist() to return false.

I've not done it myself, but have you looked into overriding onDialogClosed()?
