androidx.constraintlayout.widget.constraintlayout don't have chains that you can drag

I'm using androidx.constraintlayout.widget.ConstraintLayout in my layout and it does not show the chains, also I can't drag any widgets. I just type the constraints that I want to use.

<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="112dp"/>

here's a sample screen shot for androidx constraintLayout: androidx.constraintlayout.widget.ConstraintLayout

but when I tried switching back to : android.support.constraint.ConstraintLayout it i can see it

<android.support.constraint.ConstraintLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="112dp"/>

here's a sample screen shot for support constraintLayout: android.support.constraint.ConstraintLayout

is this a bug or something?

edit:

my current solution is to switch from:

implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

to

implementation 'com.android.support.constraint:constraint-layout:1.1.2'

but this does not solve my problem cause I don't want to use support.

if you are using latest Android update 3.3.3 then migrate to Android x from support constraint layout:

<android.support.constraint.ConstraintLayout>
</android.support.constraint.ConstraintLayout>

<androidx.constraintlayout.widget.ConstraintLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

For getting this also change gradle:

implementation com.android.support.constraint:constraint-layout:1.1.3

to

implementation androidx.constraintlayout:constraintlayout:2.0.0-alpha3

I had the same problem until I realized that I should use the Canary version to solve it. after installing Canary version beside stable version, open the project and now you can use this implementation:

implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

instead of

implementation 'com.android.support.constraint:constraint-layout:1.1.2'

Keep in mind that you may need to do the following:

  • clean project
  • rebuild
  • invalidate caches/restart

My problem solved with this method.
