Cannot resolve class of basic widget in xml

Happen on Android Studio Preview - Arctic Fox (2020.3.1) Beta 4.

enter image description here

I've tried literally everything from multiple questions on SO; Clean Build, Invalidate Caches and Restart, remove root project's .gradle and .idea, remove caches folder in .gradle, even remove and download Android Studio again, you name it.

It's been almost a day and still can't figure it out, please help, this is killing my motivation :(

In my case deleting ~/.gradle and invalidating caches did the trick.

I was facing the same problem with an old project written totally in Java. Adding the following dependency in the project gradle file solved the problem.

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.21"

For me updating the kotlin version resolved that.

I've finally managed to solve this problem myself.

The steps are to remove the current project --> clone the project again from git --> Re-import project and rebuild.

Android Studio is funny sometimes.

You can use this for imageView

<androidx.appcompat.widget.AppCompatImageView />

instead of

<ImageView />

and for textView use this

<androidx.appcompat.widget.AppCompatTextView />

instead of

<TextView />
