Best performances : XML or Java?

Who provides the best performances for Android : XML or Java ?

For example the animation. I can obtain the same result with both Java and XML, using two differents way :

• Java

private Animation outToRightAnimation() {
    Animation outToRight = new TranslateAnimation(
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, +1.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f,
            Animation.RELATIVE_TO_PARENT, 0.0f);
    outToRight.setDuration(500);
    outToRight.setInterpolator(new DecelerateInterpolator());
    return outToRight;
}

• XML

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://ift.tt/nIICcg"
    android:fillAfter="true"
    android:interpolator="@android:anim/decelerate_interpolator" >

<translate
    android:duration="500"
    android:fillAfter="true"
    android:fromXDelta="0%p"
    android:toXDelta="100%p" />
</set>

Which one is supposed to be faster ? Which one should I use ?
