java - 应用程序内的区域设置更改不起作用

Question

我正在尝试更改应用程序的语言，但它没有发生。我已经尝试了几乎所有可用的解决方案，但没有一个有效。有趣的是，大多数代码都能够更改 Facebook Account Kit Activity 的语言，但其他 Activity 的语言没有更改。下面是我的应用程序类和 list 文件。

public class MyApplication extends Application {


    private Locale locale = null;

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        if (locale != null)
        {
            newConfig.locale = locale;
            Locale.setDefault(locale);
            getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
        }
    }

    @Override
    public void onCreate()
    {
        super.onCreate();
        Configuration config = getBaseContext().getResources().getConfiguration();

        new SharedPrefManager(this).setLanguage("fr");
        String lang = new SharedPrefManager(this).getLanguage();

        locale = new Locale(lang);
        Locale.setDefault(locale);
        config.locale = locale;
        getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
        AccountKit.initialize(getApplicationContext());
    }


}
