Answer 1

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

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
