i think in your adapter view holder you are casting constraint layout with cardview. please share your adapter code. — Rajendra Mahato, Dec 31 '20 at 11:06

i selove the problem it was with the main or list gridView XML file

it must to be like this:

    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/cardview_id"
    android:clickable="true"
    android:foreground="?android:attr/selectableItemBackground"
    android:layout_width="120dp"
    android:layout_height="190dp"
    android:layout_margin="5dp" </androidx.cardview.widget.CardView>```
