I am developing a library for Android, and this library has some activities with its layouts.
In the layout, I have the next code
...
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.material.floatingactionbutton.FloatingActionButton
...
I am using Androidx.
An I get the following error:
Error inflating class android.support.constraint.ConstraintLayout
The first attempt to solve this was to changeandroid.support.constraint.ConstraintLayout
to androidx.constraintlayout.widget.ConstraintLayout
But when I do this I get the following error:
androidx.constraintlayout.widget.ConstraintLayout cannot be cast to androidx.constraintlayout.widget.Group
So I try to change to androidx.constraintlayout.widget.Group
I get the following error:
androidx.constraintlayout.widget.Group cannot be cast to android.view.ViewGroup
I did a refactor again to androidx and then I get the following error:
Didn't find class "androidx.constraintlayout.ConstraintLayout"
Any idea?
Thanks

Follow this steps
First add below
dependencies
in yourBuild.Gradle
file
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
Use this
ConstraintLayout
like this
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</androidx.constraintlayout.widget.ConstraintLayout>
Make sure you have correct imports of
ConstraintLayout
for in your activity if you have used
import androidx.constraintlayout.widget.ConstraintLayout
