Classe OnUnhandhandKeyEventListener introuvable

J'ai des erreurs sur chaque widget de conception de support. Comme la vue de recyclage, la disposition du coordinateur, etc. À chaque fois, j'ajoute un widget de conception de support qu'il affiche 

Java.lang.ClassNotFoundException: Android.view.View$OnUnhandledKeyEventListener

sur la section de mise en page. J'utilise api 28.0.0-rc01, version 4.4 Android 3.1.4. Voici mon fichier build.gradle (app)

    apply plugin: 'com.Android.application'

J'ai vérifié le fichier de classe View, mais "OnUnhandledKeyEventListener" était présent. Je ne sais pas pourquoi ce problème se produit. S'il vous plaît, dites-moi comment résoudre ce problème.

Actuellement, il n'y a malheureusement pas de solution de contournement. Android.support.v4.view.ViewCompat n'implémente pas View.OnUnhandledKeyEventListener dans le package androidx . Le bogue a été soumis ici .
