更改日/夜主题将语言更改为默认语言-kotlin

Question

我不知道这个问题是否已经存在，但我没有找到任何解决方案。 我在移动应用程序中有两种语言（英语和西班牙语）和日/夜主题。当我更改语言时，我的应用程序运行良好，但是当我更改主题时，语言会自动更改为默认语言。 谢谢！ 代码：

class MyPreferences(context: Context?) {

companion object {
    private const val DARK_STATUS = "DARK STATUS"
    private const val LANGUAGE ="language"
}

private val preferences = PreferenceManager.getDefaultSharedPreferences(context)

var darkMode = preferences.getInt(DARK_STATUS, 0)
    set(value) = preferences.edit().putInt(DARK_STATUS, value).apply()


var lang = preferences.getInt(LANGUAGE, 0)
    set(value) = preferences.edit().putInt(LANGUAGE, value).apply()

}

 fun chooseThemeDialog() {
    val light:String =getString(R.string.light)
    val dark:String =getString(R.string.dark)
    val systemDefault:String =getString(R.string.system_default)

    val builder = AlertDialog.Builder(this)
    builder.setTitle(getString(R.string.theme))
    val styles = arrayOf(light,dark,systemDefault)
    val checkedItem = MyPreferences(this).darkMode
   

    builder.setSingleChoiceItems(styles, checkedItem) { dialog, which ->
        when (which) {
            0 -> {
                AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO)
                delegate.applyDayNight()
                MyPreferences(this).darkMode = 0

                dialog.dismiss()
            }
            1 -> {
                AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)
                delegate.applyDayNight()
                MyPreferences(this).darkMode = 1


                dialog.dismiss()
            }
            2 -> {
                AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM)
                delegate.applyDayNight()
                MyPreferences(this).darkMode = 2
               
                dialog.dismiss()
            }
        }

    }
    val dialog = builder.create()
    dialog.show()
}

 fun chooseLanguageDialog() {
    val english = getString(R.string.english)
    val spanish = getString(R.string.spanish)
    val languages = arrayOf(english, spanish)
    val builder = AlertDialog.Builder(this)
    builder.setTitle(getString(R.string.choose_language_text))
    val yes=MyPreferences(this).darkMode
    val checkedItem = MyPreferences(this).lang

    builder.setSingleChoiceItems(languages, checkedItem) { dialog, which ->
        when (which) {
            0 -> {
                setLocate("en")
                recreate()
