Is it correct way or any other way is there.

Try to put the click listener on the child view of the card like
<android.support.v7.widget.CardView
android:id="@+id/cardRight"
android:layout_width="0dp"
android:layout_height="0dp"
app:cardCornerRadius="10dp"
android:elevation="4dp"
android:layout_marginEnd="4dp"
android:layout_marginStart="4dp"
android:layout_marginTop="8dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="@+id/guideline"
app:layout_constraintTop_toBottomOf="@+id/cardTop">
<LinearLayout
android:id="@+id/layRight"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="6"
android:orientation="vertical"
android:gravity="center">
<ImageView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="3"
android:src="@drawable/illustration"
android:scaleType="centerCrop"/>
</LinearLayout>
</android.support.v7.widget.CardView>
and on your activity define the linearLayout and try to set onClicklistener with
