ObjectAnimator not fading in

Question

I am trying to play a set of animations sequentially using the Animator set. Everything is working except for the alpha animation(set1). It is changing from 0.25f to 1 but it is not fading throughout the animation and at the end of the set1 animation it is changing from 0.25 to 1 and not taking in consideration the setDuration(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?

I am using the wonderful nineoldandroids library to implement this.

@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(); }    

Answer 1

While working on 4.0+

ObjectAnimator alphaAnimation = ObjectAnimator.ofFloat(image, View.ALPHA, 0,1); 

Answer 2

try this.

ObjectAnimator.ofFloat(image, "alpha", 0.25f, 1, 1)
