| public void | onActivityCreated(android.os.Bundle savedInstanceState)
super.onActivityCreated(savedInstanceState);
final ArrayAdapter<LocaleInfo> adapter = constructAdapter(getActivity());
setListAdapter(adapter);
|
| public void | onListItemClick(android.widget.ListView l, android.view.View v, int position, long id)Each listener needs to call {@link #updateLocale(Locale)} to actually change the locale.
We don't call {@link #updateLocale(Locale)} automatically, as it halt the system for
a moment and some callers won't want it.

|
| public static void | updateLocale(java.util.Locale locale)Requests the system to update the system locale. Note that the system looks halted
for a while during the Locale migration, so the caller need to take care of it.
try {
IActivityManager am = ActivityManagerNative.getDefault();
Configuration config = am.getConfiguration();
// Will set userSetLocale to indicate this isn't some passing default - the user
// wants this remembered
config.setLocale(locale);
am.updateConfiguration(config);
// Trigger the dirty bit for the Settings Provider.

} catch (RemoteException e) {
