I got it!
The method retrieveUserCalendars() fills the callListEntries (the labels)
and calListEntryValues (the IDs) with the values you want to put into the
list preference.
Regards!
public class Preferences extends PreferenceActivity {
> private CharSequence[] calListEntries = null;
private CharSequence[] calListEntryValues = null;
> @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
>
> ListPreference calendarList = (ListPreference)
> findPreference("gcalendar_list");
retrieveUserCalendars();
calendarList.setEntryValues(calListEntryValues);
calendarList.setEntries(calListEntries);
> }
> private void retrieveUserCalendars() {
//...
}
}
