ImageView Transition Animation after loading

I want to load a ImageView and then fade it in. But for now it doesn't work.

Here is the code:

        getActivity().runOnUiThread(new Runnable() {
            @Override
            public void run() {
                // This code will always run on the UI thread, therefore is safe to modify UI elements.
                ProgressBar pb_befree = (ProgressBar) getActivity().findViewById(R.id.pb_befree);
                ImageView befree = (ImageView) getActivity().findViewById(R.id.befree);
                befree.setImageResource(R.drawable.sc_befreejpg);
                pb_befree.setVisibility(View.GONE);

                Animation animFade;
                animFade = AnimationUtils.loadAnimation(getActivity(), R.anim.motivation_fadein);
                befree.setAnimation(animFade);

                befree.setVisibility(View.VISIBLE);

XML:

<?xml version="1.0" encoding="utf-8"?>
<set>
    <alpha xmlns:android="http://ift.tt/nIICcg"
        android:propertyName="alpha"
        android:valueType="floatType"
        android:valueFrom="0"
        android:valueTo="100"
        android:duration="500"/>

</set>

I really don't know what I am doing wrong. I get no Exception or something. The animation is just missing.
