我有一个支持多种语言的旧项目。我想升级支持库和目标平台，在迁移到Androidx之前，一切正常，但现在更改语言无效！

我使用此代码更改App的默认语言环境

private static Context updateResources(Context context, String language)
{
    Locale locale = new Locale(language);
    Locale.setDefault(locale);

    Configuration configuration = context.getResources().getConfiguration();
    configuration.setLocale(locale);

    return context.createConfigurationContext(configuration);
}

并在每个活动上通过attachBaseContext这样的覆盖调用此方法：

@Override
protected void attachBaseContext(Context newBase)
{
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
    String language = preferences.getString(SELECTED_LANGUAGE, "fa");
    super.attachBaseContext(updateResources(newBase, language));
}

我尝试其他方法来获取字符串，但我注意到了吗？getActivity().getBaseContext().getString工作，而getActivity().getString不是工作。即使以下代码也不起作用，并且始终app_name在默认资源string.xml中显示vlaue。

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/app_name"/>

我在https://github.com/Freydoonk/LanguageTest中共享示例代码

也getActivity()..getResources().getIdentifier行不通，总是返回0！

我在实时应用程序上遇到 UnsupportedOperationException 崩溃。所有崩溃都与 Moto Android 11 设备有关。可以看出它与 onKeyUp 有某种关系。但仍然不知道如何重现或解决这个问题。任何帮助，将不胜感激。

Fatal Exception: java.lang.UnsupportedOperationException: Tried to obtain display from a Context not associated with  one. Only visual Contexts (such as Activity or one created with Context#createWindowContext) or ones created with Context#createDisplayContext are associated with displays. Other types of Contexts are typically related to background entities and may return an arbitrary display.
