选择不同的应用区域设置后无法翻译后面的片段

遇到这样的问题。在我的应用程序中，我实现了本地化，但它应该与系统的语言环境分开为我工作。我在教程的帮助下编写了 LocaleHelper 类

import android.content.Context
import android.os.Build
import com.example.core.utils.preferences.AppSharedPreferences
import timber.log.Timber
import java.util.*

class LocaleHelper(private val appPreferences: AppSharedPreferences) {

   fun onAttach(context: Context): Context? {
       val lang = getPersistedData(Locale.getDefault().language)
       Timber.d("Locale/LocaleHelper.onAttach.lang = $lang")
       return setLocale(context, lang!!)
   }

    fun onAttach(context: Context, locale: String): Context? {
        val lang = getPersistedData(locale)
        return setLocale(context, lang!!)
    }

    fun setLocale(context: Context, language: String): Context? {
        persist(language)
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            return updateResources(context, language)
        }
        return updateResourcesLegacy(context, language)
    }

    private fun getPersistedData(locale: String): String? {
        Timber.d("Locale/LocaleHelper.getPersistData.lang = $locale")
        return appPreferences.loadChangingByUserLocale(locale)
    }

    private fun persist(language: String) {
        appPreferences.saveChangingByUserLocale(language)
    }

    private fun updateResources(context: Context, language: String): Context? {
        val appLocale = Locale(language)
        val configuration = context.resources.configuration

        Locale.setDefault(appLocale)
        configuration.apply {
            setLocale(appLocale)
            setLayoutDirection(appLocale)
        }
        return context.createConfigurationContext(configuration)
    }

    @Suppress("DEPRECATION")
    private fun updateResourcesLegacy(context: Context, language: String): Context? {
        val appLocale = Locale(language)
        val resource = context.resources
        val configuration = resource.configuration

        Locale.setDefault(appLocale)
        configuration.locale = appLocale
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            configuration.setLayoutDirection(appLocale)
        }
        resource.updateConfiguration(configuration, resource.displayMetrics)
        return context
    }
}

在主页上，我制作了一个下拉列表，点击即可打开

私人乐趣 preparePopupWindowLangs(): PopupWindow? { val popup = PopupWindow(view!!.context).apply { width = 250 height = WindowManager.LayoutParams.WRAP_CONTENT isOutsideTouchable = true isFocusable = true contentView = contentList() } logger.preparePopupWindow() 返回弹出窗口 }

    private fun contentList(): ListView {
        val localesAdapter = LanguagesPopupAdapter(context!!, prepareLocalesList(viewModel.localesNames))
        localesAdapter.notifyDataSetChanged()
        val listView = ListView(context).apply {
            adapter = localesAdapter
            onItemClickListener = popupOnItemClick()
        }
        return listView
    }

    private fun prepareLocalesList(@StringRes array: Array<Int>): List<String> {
        val locales: MutableList<String> = mutableListOf()
        array.forEachIndexed { index, locale ->
            locales.add(index, resources.getString(locale))
        }
        return locales
    }

    private fun popupOnItemClick(): OnItemClickListener {
        val itemClick = OnItemClickListener { parent, view, position, id ->
            val fadeInAnimation: Animation =
                AnimationUtils.loadAnimation(context, R.anim.fragment_fade_enter)
            fadeInAnimation.duration = 10
            view!!.startAnimation(fadeInAnimation)
            val selectedItemText = view.findViewById<TextView>(R.id.language_tv).text.toString()
            langs_popup.text = selectedItemText
            popup!!.dismiss()
            changeLocale(viewModel.localesIndexes[position])
        }
        return itemClick
    }

通过从列表中选择，我更改了文本

 private fun changeTextAfterLanguageSelection(lang: String) {
        val context = viewModel.localeHelper.setLocale(context!!, lang)
        val resources = context!!.resources
        login_tv.text = resources.getString(R.string.field_header_login)
        login_et.hint = resources.getString(R.string.hint_login)
        password_tv.text = resources.getString(R.string.field_header_password)
        password_et.hint = resources.getString(R.string.hint_password)
        auth_progress_button.setButtonName(context, R.string.btn_enter)
        prepareLocalesList(viewModel.localesNames)
        setPopupTitleText()
    }

我还添加了一种方法来更改片段中的文本

override fun onAttach(context: Context) {
        super.onAttach(viewModel.localeHelper.onAttach(context)!!)
    }

添加了在活动中为应用程序设置区域设置的方法

 override fun attachBaseContext(newBase: Context?) {
        super.attachBaseContext(localeHelper.onAttach(newBase!!, appPreferences.loadChangingByUserLocale("ru")!!)))
   }

结果，我得到以下信息：在具有 API 22 的模拟器中，一切正常，但已经在 API 29 上，当切换到另一个片段时，不执行翻译，而只执行应用程序时的语言环境已推出作品。我知道选择语言时可以选择重新启动活动，但这种方法不适合我的任务。我正在实施 SingleActivity 技术。
