title: ObjectAnimator not fading in
body: <p>I am trying to play a set of animations sequentially using the <code>Animator</code> set. Everything is working except for the alpha animation(<code>set1</code>). It is changing from 0.25f to 1 but it is not fading throughout the animation and at the end of the <code>set1</code> animation it is changing from 0.25 to 1 and not taking in consideration the <code>setDuration</code>(as a result I am not getting the fade in effect). So I don't have the fade in effect... When I do this animation by itself the fade in effect is there....Any ideas?</p>
  
  <p>I am using the wonderful <a href="http://nineoldandroids.com/" rel="noreferrer">nineoldandroids</a> library to implement this.</p>
  
  <pre><code>@Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      final ImageView image = (ImageView) findViewById(R.id.image);
      final AnimatorSet set = new AnimatorSet();
      set.play(ObjectAnimator.ofFloat(image, "translationX", 0, 100).setDuration(3000));
  
      final AnimatorSet set1 = new AnimatorSet();
      //THIS IS THE PROBLEMATIC ANIMATION!!
      set1.play(ObjectAnimator.ofFloat(image, "alpha", 0.25f, 1).setDuration(3000));
  
      final AnimatorSet set2 = new AnimatorSet();
      set2.play(ObjectAnimator.ofFloat(image, "translationX", 100, 200).setDuration(3000));
  
      final AnimatorSet set3 = new AnimatorSet();
      set3.playSequentially(set,set1,set2);
      set3.start();
  }   
  </code></pre>
