Resize an stretched Vector in ImageView - Android Studio

Question

I've been searching this for a while but didn't found nothing. How can I resize an Vector inside an ImageView? I tried a lot of things but didn't work. The vector is shown stretched like that:

My code is:

<com.google.android.material.card.MaterialCardView
        android:id="@+id/card_view"
        android:layout_width="240dp"
        android:layout_height="140dp"
        app:cardCornerRadius="8dp"
        app:cardElevation="8dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <ImageView
            android:id="@+id/buton_add_image"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/ic_add_image"
            android:contentDescription="@string/add_image" />

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