Android Kotlin App Die Symbolleiste wird nicht angezeigt ⇐ Android

[Anonymous]

Ich habe das in der Java -Version arbeiten, aber ich fehlt eindeutig etwas, wenn ich es in Kotlin umschreibe. Ich möchte eine Symbolleiste anstelle der TopApp -Leiste verwenden. In der Dokumentation ist dies alles, was ich zum Laufen bringen muss. /p>
