Answer 1

You can make class which extends Application. There you can override one method which gets called everytime you change configuration (example when screen orientation gets changed).

Something like:

public class MyApplication extends Application {
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        setLocale();
    }

    private void setLocale() {
        Locale locale = new Locale("fa_IR");
        Locale.setDefault(locale);
        Configuration config = new Configuration();
        config.locale = locale;
        getBaseContext().getResources().updateConfiguration(config,
              getBaseContext().getResources().getDisplayMetrics());
    }
}

And dont forget to declare it in the manifest: example of Application class

In AndroidManifest.xml:
