Android ObjectAnimator: Padding after scale animation

Question

I have a problem with scaleX and scaleY animations using ObjectAnimator.

At the end of animation, the Drawable inside is resized but not the size of the border of the ImageView.

Schema of my problem : click here

XML ImageView code

    <ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/avenger"
    android:background="@null"
    android:id="@+id/vaisseau"
    android:adjustViewBounds="true"
    android:layout_above="@+id/santeBouclier"
    android:layout_centerHorizontal="true" />

Animation code:

        ImageView avenger = (ImageView)this.jeu.findViewById(R.id.vaisseau);

        AnimatorSet resizeAvenger = new AnimatorSet();
        ObjectAnimator animResizeX = ObjectAnimator.ofFloat(avenger, "scaleX", 1f, 0.3f);
        animResizeX.setDuration(4000);
        ObjectAnimator animResizeY = ObjectAnimator.ofFloat(avenger, "scaleY", 1f, 0.3f);
        animResizeY.setDuration(4000);
        resizeAvenger.playTogether(animResizeX, animResizeY);
        resizeAvenger.start();

I think my problem is here :

Before the animation :
avenger.getScaleX() = 1
avenger.getWidth() = 190

After the animation :
avenger.getScaleX() = 0.3
avenger.getWidth() = 190

Answer 1

multiply width and scale factor as said here:

getWidth not returning different value after scaling
