How to add cardview in layout xml in AndroidX

After upgraded to AndroidX

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp">

gives a error

The following classes could not be found: - android.support.v7.widget.CardView (Fix Build Path, Edit XML, Create Class)

dependencies {

    implementation 'androidx.appcompat:appcompat:1.0.0'
    
    implementation 'androidx.cardview:cardview:1.0.0'

but I don't know how to use CardView in xml under AndroidX

Thank you

The class has changed to:

androidx.cardview.widget.CardView

If you want to use the old class names, you need to add android:enableJetifier=true to your gradle.properties and use the appcompat dependencies instead.

I think the Best Approach should be like, understanding the problem statement first.

Scenario:

  • Search for the library which Google Inc has changed for "AndroidX" and include in project

Solution :

Go to Artifact Mappings page of Android Developer Site and Search for your desired library.

enter image description here

Now go to AndroidX Releases page and check for the current version number

enter image description here

now go to build.gradle[module.app] add the library you want. (ie. CardView in my case) and press
Sync Now and necessary files will be added to your project by gradle.

See the image below:

enter image description here

Now in xml file you should get CardView or something you have just imported.

NB: pictures included here are (the first two) taken from Android Developer's Page which belongs to Google Inc and could be different depending on the time you see. See this post's posting time.

You have 2 different options:

Just add:

implementation 'com.google.android.material:material:1.2.0'

and in your xml you can use:

 <com.google.android.material.card.MaterialCardView
  ...>
  • Androidx CardView

Just add:

implementation 'androidx.cardview:cardview:1.0.0'

and in your xml you can use:

<androidx.cardview.widget.CardView>

They are different:

MaterialCardView extends androidx.cardview.widget.CardView and provides all of the features of CardView and

  • add support for checking and dragging
  • uses a MaterialComponents theme by default (it uses by deafult the style Widget.MaterialComponents.CardView)
  • support the ShapeAppearanceModel
  • adds attributes for customizing the stroke

  • I'm sorry but all reference links you posted is now invalid. Is your answer correct with current android version? – nynohu Jul 27 '20 at 07:48
  • @nynohu Thanks for feedback.Links just fixed. And yes both work with current android version. – Gabriele Mariotti Jul 27 '20 at 08:00
  • @GabrieleMariotti thank you for this. The docs and codelabs seem to be horribly out of sync with 4.0.1 now. Makes it a nightmare to try and learn this stuff right now. – Paula Livingstone Aug 17 '20 at 10:05

For AndroidX, Add in gradle dependencies

implementation 'androidx.cardview:cardview:1.0.0'

Then in xml-layout use

<androidx.cardview.widget.CardView

Add 'androidx.cardview:cardview:1.0.0' in gradle dependencies and modify xml accordingly.

Replace this line

from

<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"

to

<androidx.cardview.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"

This will work fine in AndroidX.

I had the same problem in Android Studio 3.5.1. It worked for me:

def cardview_version = "1.0.0"
implementation "androidx.cardview:cardview:$cardview_version"


xmln: <androidx.cardview.widget.CardView>....
0

Changes in : 1. build.gradle(:app)

dependencies {
...
implementation 'androidx.cardview:cardview:1.0.0' 
....
}

2. in xml section:

<androidx.cardview.widget.CardView>
...
</androidx.cardview.widget.CardView>
