Android - Set default preference values for a modern fragment-based PreferenceActivity
Raw
MyApplication.java
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
// we cannot call setDefaultValues for multiple fragment based XML preference
// files with readAgain flag set to false, so always check KEY_HAS_SET_DEFAULT_VALUES
if (!PreferenceManager.getDefaultSharedPreferences(getApplicationContext())
.getBoolean(PreferenceManager.KEY_HAS_SET_DEFAULT_VALUES, false)) {
PreferenceManager.setDefaultValues(getApplicationContext(), R.xml.pref_general, true);
PreferenceManager.setDefaultValues(getApplicationContext(), R.xml.pref_labels, true);
PreferenceManager.setDefaultValues(getApplicationContext(), R.xml.pref_appearance, true);
}
}
