问题
I am re-using ListPreference for a setting which I store only in the database. How can I prevent it from storing/persisting any data to the preference file?
回答1:
Subclass it, override shouldPersist() to return false.
回答2:
I've not done it myself, but have you looked into overriding onDialogClosed()?
