        behavior.onNestedPreScroll(coordinatorLayout, appBarLayout, null, 0, heigthPx, new int[]{0, 0});
    }
}

NestedScrollView should contain only one child. But you have added 2

CardView
TextView

Remove the following TextView and it should work

       <TextView
            android:id="@+id/txt_descripcion"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Descripcion"
            android:layout_marginTop="130dp"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"/>

Nested Scroll View cannot inflate class
