Android Studio 3 - Constraint layout editor is not working

Question

I recently installed android studio 3 but The constraint layout shows a grey window..I tried everything but I couldn't fix the the problem

Thanks in advance for any help provided:

enter image description here

XML code:

<?xml version="1.0" encoding="utf-8"?> 
<android.support.constraint.ConstraintLayout 
    xmlns:android="schemas.android.com/apk/res/android"; 
    xmlns:app="schemas.android.com/apk/res-auto"; 
    xmlns:tools="schemas.android.com/tools"; 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.chihaoui.myapplication.MainActivi‌ty"> 
</android.support.constraint.ConstraintLayout>

The app did not work on my phone but I didn't try the emulator — max taylor, Jan 15 '18 at 13:40
"did not work" - Why exactly? Try the emulator. I suspect if there is no error and app runs fine, then the problem has to do with the design editor — Pulak, Jan 15 '18 at 13:43

This is so weird, but Build -> Make project, made the layout editor to work. – netcyrax Nov 02 '19 at 08:55

I had a similar problem. My case is resolved by adding the following lines on app/build.gradle:

implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation('com.android.support:appcompat-v7:28.0.0') {
    force = true
}

Note the force = true part.

Alternatively, you can use the AndroidX Support Library instead of v7. Source: https://developer.android.com/topic/libraries/support-library/packages#v7 – MD Naseem Ashraf Mar 10 '19 at 07:02

in build.gradle, just change:

androidx.constraintlayout:constraintlayout:2.1.3

to

androidx.constraintlayout:constraintlayout:2.0.4

this worked for me, seems like 2.1.3 is broken with compiled 31 SDK. – May 02 '22 at 14:38
