How can a PreferenceActivity use a custom preference file

Question

My first attempt at preferences was without knowledge of PreferenceActivity. So now I have an app that stores all user preferences in a specific preference file.

Answer 1

You could read all the preferences at the beginning of your app, and then store them in the Preferences using

Editor e = PreferenceManager.getDefaultSharedPreferences(getBaseContext()).edit();
e.putBoolean("yourPreference", true);
e.putString("yourOtherPreference", "This is the Value");
...
e.commit();

I hope that helps
