I've read several posts in StackOverflow I change style, sdk ,but it doesn't work any way

Here are some rendering error android studio gave me

java.lang.IllegalArgumentException: java.lang.ClassCastException@53dcf95b java.lang.IllegalArgumentException: java.lang.ClassCastException@24df40fa java.lang.IllegalArgumentException: java.lang.ClassCastException@269b81fb

maybe you need to change the android API that you are using – Wassim Ben Hssen Jul 09 '19 at 15:40 — Wassim Ben Hssen, Jul 09 '19 at 15:40

For me I switching to text to design again and again. And sometime switching to preview and gradle at the right corner. This does the trick. Hope it help you

You may try some options:

Clean Project
Rebuild Project
Invalidate caches / Restart
Switching Multiple time Text / Design [Answerd by @Rajkumar Sharma]
Change API level
Change Theme
You may close your current project and Open another new to test that the problem is in your current project or in the Android Studio.
Check Manifest
