Bug description

Hello

getLocalizedString in the Adapter is reconfiguring the locale for every item completely destroying the performances f the drawer.

I would advise to set the locale once in activity after onCreate

    val locale = prefs.appLanguage.locale()
    
    // DEBUG: Toast to verify expected locale
    android.widget.Toast.makeText(this, "Target: ${locale.toLanguageTag()} | System: ${java.util.Locale.getDefault().toLanguageTag()}", android.widget.Toast.LENGTH_LONG).show()

    val localeList = androidx.core.os.LocaleListCompat.create(locale)
    androidx.appcompat.app.AppCompatDelegate.setApplicationLocales(localeList)

Steps to reproduce the bug

Open app drawere
Scroll a long list of app and look at logcat

Expected behavior

App list should scroll smoothly

thanks for the report bf9999d has fixed this issue.

Why not simply using system components;: https://developer.android.com/reference/androidx/appcompat/app/AppCompatDelegate?hl=en#setApplicationLocales(androidx.core.os.LocaleListCompat)

Instead of reinvinting the wheel and having to cache all Strings?

that would work until you try to go back to the system language then it will reset back to the last used language which isnt what i want

[ChristopheVersieux]

Working fine:

val locale = prefs.appLanguage.locale()

// DEBUG: Toast to verify expected locale
//android.widget.Toast.makeText(this, "Target: ${locale.toLanguageTag()} | System: ${java.util.Locale.getDefault().toLanguageTag()}", android.widget.Toast.LENGTH_LONG).show()

val localeList = if (prefs.appLanguage == app.wazabe.mlauncher.data.Constants.Language.System) {
    androidx.core.os.LocaleListCompat.getEmptyLocaleList()
} else {
    androidx.core.os.LocaleListCompat.create(locale)
}
androidx.appcompat.app.AppCompatDelegate.setApplicationLocales(localeList)

Just send an empty list and you are back to system locale.
