MaterialCardView crashes with material:1.1.0

Question

I am using MaterialCardView as my cardview layout. Now, Android-studio started showing me that instead of current implementation \"com.google.android.mat

Answer 1

The error is in the stacktrace:

Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).

With the version 1.1.0 you have to inherit from a Theme.MaterialComponents.

Change your app theme to

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
  <!-- ....  -->
</style>

Answer 2

It works after changing this <style name="AppTheme" parent="Theme.AppCompat.DayNight> to <style name="AppTheme" parent="Theme.MaterialComponents.DayNight">

Answer 3

you can just keep it in your materialcardview itself also:

 <com.google.android.material.card.MaterialCardView
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:cardCornerRadius="8dp"
     **** android:theme="@style/Theme.MaterialComponents.Light"  *****
      app:cardElevation="8dp">

Answer 4

In my case I just added the android:theme="" attribute and it worked. My Material Card View element is as below -

<com.google.android.material.card.MaterialCardView
            android:id="@+id/edit_profile_card"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginStart="@dimen/dp_16"
            android:layout_marginTop="@dimen/dp_10"
            android:layout_marginEnd="@dimen/dp_16"
            android:layout_marginBottom="@dimen/dp_10"
            **android:theme="@style/Theme.MaterialComponents.DayNight"**
            app:cardCornerRadius="@dimen/dp_10"
            app:cardElevation="@dimen/dp_20"
            app:state_dragged="false">

           ....
           ....

        </com.google.android.material.card.MaterialCardView>

Answer 5

You need to change your AppTheme to have it's parent theme as a descendant of MaterialComponent

In your particular case changing the AppTheme from

  <style name="AppTheme" parent="Theme.AppCompat.DayNight">

to

  <style name="AppTheme" parent="Theme.MaterialComponents.DayNight">

should fix the issue.

Answer 6

If after changing the theme to Theme.MaterialComponents in the styles.xml didn't work then make sure you have added style tag in the MaterialCard.

style="@style/Widget.MaterialComponents.CardView"
