        View rootView = inflater.inflate(R.layout.activity_city, container, false);

        return rootView;
    }


}

Below is the layout code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
    android:layout_height="match_parent"
   >
    <!-- A CardView that contains a TextView -->
    <android.support.v7.widget.CardView
        xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:id="@+id/card_view"
        android:layout_gravity="center"
        android:layout_width="200dp"
        android:layout_height="200dp"
       >

        <TextView
            android:id="@+id/info_text"
            android:layout_width="match_parent"
            android:layout_height="match_parent" 

            />
    </android.support.v7.widget.CardView>
</LinearLayout>

Thanks in advance

This error is caused because you are probably using AndroidX but you are using this dependency:

implementation 'com.android.support:cardview-v7:27.1.1'

Change to AndroidX CardView dependency

implementation 'androidx.cardview:cardview:1.0.0'

and change your class into the layout:

 <androidx.cardview.widget.CardView

You may get this error because you may have copied the code from a web page and pasted it as it is in your project especially in layouts. Please don't do that and if you do that you should see the design part if it is OK or not.I also got the same error and solved it by implementing by myself.

Just locate your cardview layout in your xml file, for example 

<android.support.v7.widget.CardView......</android.support.v7.widget.CardView>

and replace it with

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

If this error happened in AndroidX, you need to use following dependencies to fix this error:

implementation 'androidx.cardview:cardview:1.0.0'

the issue can also be caused by using the androidX try to change to <androidx.cardview.widget.CardView and the crashing should be ok. One tip, check if you see the layout in the preview.

in the gradle it shoud be like : implementation 'androidx.cardview:cardview:1.0.0'

Answers above didn't help. Works fine after adding 

<android.support.v7.widget.CardView
    ...
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:cardBackgroundColor="@android:color/transparent">

Can't explain.

While checking all your dependency just check the related JAVA class file that is it extends AppCompatACtivity or not. Sure this will help you.

I solved this by adding updated cardview and appcompat on the app/build.gradle

dependencies {
    ...
    compile 'com.android.support:appcompat-v7:23.4.0'    
    compile 'com.android.support:cardview-v7:23.4.0'
    compile 'com.android.support:recyclerview-v7:23.4.0'
    }

Then rebuild the project

You need to specify a dependency on the v7 cardview library

Edit build.gradle and specify "com.android.support:cardview-v7:21.0.+" in the dependencies section.

To fix this problem . first you must add cardview from the

  1. Close the main project.
  2. Remove the android-support-v7-appcompat .
  3. Restart the Eclipse.
  4. Add the android-support-v7-appcompat .
  5. Build the project.
  6. Then open the main project and build all the three projects.
  7. The error still remains. Restart eclipse. That's it.

That works for me.
