Answer 1

Make sure constraint layout is updated to latest version:

implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

And replace your xml tag names

<androidx.constraintlayout.ConstraintLayout>

with

<androidx.constraintlayout.widget.ConstraintLayout>

in every place where it appears using this shortcut:

Windows: CTRL + SHIFT + R

Mac: COMMAND + SHIFT + R

Answer 2

Since the Android Studio is updated to 3.3 it will pop this error. I resolved it by upgrading the version for constraint layout in the build.gradle of the app level:

implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

TO

implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

Answer 3

In AndroidStudio 3.4 I had to downgrade to

implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

to get it working again.

Answer 4

Android Studio is updated version 3.3. Please remove the previous version constraintLayout

my case used this

implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'

Thank you

Answer 5

Just replace

<androidx.constraintlayout.ConstraintLayout>

with

<androidx.constraintlayout.widget.ConstraintLayout>

In your project's xml files.

You can use Replace in Path shortcut in mac (⇧⌘F or ⇧⌘R) and windows (Ctrl+Shift+R)

Answer 6

In AndroidStudio 3.3 RC2 I got it resolved by upgrading -

implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

to

implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

in build.gradle (Module: app)

Note: This solution is also valid for the release version 3.3 (as per below comment by FireZenk), 3.5.2 (as per below comment by user2350644)
