Android - Blinking image using the Alpha fade animation

I've been struggling for a few days on this, finally just decided to ask. It's so simple I've got to be missing something very basic.

I have an XML layout page with an image defined. I have two anim XML pages, one to change alpha from 0 to 1, and the other from 1 to 0 in order to create a "blinking" effect. So the alphaAnimation is defined in XML, I just need to call it.

The image pops up, but there's no looping blinking effect.

public class blinker extends Activity {

   //create name of animation
Animation myFadeInAnimation;
Animation myFadeOutAnimation;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.scanning_view);

 //grab the imageview and load the animations
    ImageView myImageView = (ImageView) findViewById(R.id.blinkingView01); 
    Animation myFadeInAnimation = AnimationUtils.loadAnimation(null, R.anim.fade_in);
    Animation myFadeOutAnimation = AnimationUtils.loadAnimation(null, R.anim.fade_out);

//fade it in, and fade it out. 
    myImageView.startAnimation(myFadeInAnimation);
    myImageView.startAnimation(myFadeOutAnimation);
     }
}   

Two XML Animation layouts in Anim resource:

<?xml version="1.0" encoding="UTF-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android"> 
    <alpha android:fromAlpha="0.0" 
    android:toAlpha="1.0" 
    android:interpolator="@android:anim/accelerate_interpolator"  
    android:duration="50" android:repeatCount="infinite"/> 
 </set> 

And the other:

 <?xml version="1.0" encoding="UTF-8"?>
 <set xmlns:android="http://schemas.android.com/apk/res/android"> 
    <alpha android:fromAlpha="1.0" android:toAlpha="0.0" 
    android:interpolator="@android:anim/accelerate_interpolator"  
    android:duration="1000" android:repeatCount="infinite"/> 
</set>
