Android动态改变语言并自动刷新菜单.

Locale locale=null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        String languageToLoad  = "zh";
         locale = new Locale(languageToLoad);
        Locale.setDefault(locale);
        Configuration config = new Configuration();
        config.locale = locale;
        getBaseContext().getResources().updateConfiguration(config, null);
        //getBaseContext().getResources().getDisplayMetrics()
        Log.v("log:","local is changed!");
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        setContentView(R.layout.activity_main);
