你还在重写attachBaseContext自定义多语言切换吗？
你还需要自己用轻量级存储（SharedPreferences、datastore）之类的来保存你切换的语言吗？
你还需要自己编写重启活动逻辑吗?
比如：

override fun attachBaseContext(newBase: Context?) {if(newBase==null) {super.attachBaseContext(newBase)return}val sp = newBase.getSharedPreferences("share_data", Context.MODE_PRIVATE)val language = sp.getString("language", Locale.getDefault().language)var locale = Locale.getDefault()if (language.equals("en", ignoreCase = true)) {locale = Locale.ENGLISH} else if (language.equals("ko", ignoreCase = true)) {locale = Locale.KOREA} else if (language.equals("zh", ignoreCase = true)) {locale = Locale.SIMPLIFIED_CHINESE} else if (language.equals("zh_TW", ignoreCase = true)) {locale = Locale.TRADITIONAL_CHINESE} else if (language.equals("ja", ignoreCase = true)) {locale = Locale.JAPAN} else if (language.equals("de", ignoreCase = true)) {locale = Locale.GERMANY} else if (language.equals("pt", ignoreCase = true)) {locale = Locale("pt")} else if (language.equals("es", ignoreCase = true)) {locale = Locale("es")} else if (language.equals("fr", ignoreCase = true)) {locale = Locale.FRENCH} else if (language.equals("ru", ignoreCase = true)) {locale = Locale("ru")} else if (language.equals("it", ignoreCase = true)) {locale = Locale.ITALY}Log.d("TAG", "changeAppLanguage: $language")val metrics = newBase.resources.displayMetricsval configuration = newBase.resources.configurationconfiguration.setLocale(locale)if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {super.attachBaseContext(newBase.createConfigurationContext(configuration));} else {newBase.resources.updateConfiguration(configuration, metrics);super.attachBaseContext(newBase)}

各应用语言偏好设定  |  Android 开发者  |  Android Developers
大体来说就三步

• 将受支持的语言添加到系统设置 localeConfig="@xml/locale_configs"

  <manifest>...<application...android:localeConfig="@xml/locales_config"></application>
  </manifest>

  <?xml version="1.0" encoding="utf-8"?>
  <locale-config xmlns:android="http://schemas.android.com/apk/res/android"><locale android:name="en-US"/>使用“英语（美国）”作为最终回退语言区域<locale android:name="en-GB"/> 英语（英国）<locale android:name="fr"/> 法语<locale android:name="ja"/> 日语<locale android:name="zh-Hans-MO"/> 中文（简体，澳门）<locale android:name="zh-Hant-MO"/> 中文（繁体，澳门）
  </locale-config>

• 注册自动存储的语言服务

  <application...<serviceandroid:name="androidx.appcompat.app.AppLocalesMetadataHolderService"android:enabled="false"android:exported="false"><meta-dataandroid:name="autoStoreLocales"android:value="true" /></service>...
  </application>

使用

        // 使用AndroidX支持库获取当前的应用程序语言环境val currentLocaleName = if (!AppCompatDelegate.getApplicationLocales().isEmpty) {// 从列表中获取当前的应用程序区域设置AppCompatDelegate.getApplicationLocales()[0]?.displayName} else {// 获取默认的系统区域设置Locale.getDefault().displayName}// 语言设置为“西班牙雨”xxx.setOnClickListener {val localeList = LocaleListCompat.forLanguageTags("es")AppCompatDelegate.setApplicationLocales(localeList)}
