Set start offset for a repeating animation only for start

Question

I want to put some delay for starting of an animation. So, when an animation is not going to repeat, we can easily use startOffset property. The thing is I have an animation which is going to repeat infinitely. But I have to start it with a delay, so when I use startOffset, the animation always repeat with that delay which is not what I want. Also I don't want to use Handler for creating delay.

EDIT:

I have never used ObjectAnimator. My code is like below but it doesn't animating. What is my mistake?

ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(view, "translationX", 1000, -1000);
objectAnimator.setDuration(ANIMATION_DURATION);
objectAnimator.setRepeatMode(ValueAnimator.RESTART);
objectAnimator.setRepeatCount(ValueAnimator.INFINITE);
objectAnimator.setStartDelay((5 - i) * INTERVAL);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.play(objectAnimator);
animatorSet.start();

`Also I don't want to use Handler for creating delay` - why? — azizbekian, Oct 10 '17 at 07:46
Because the animation will be assigned to many Views and anywhere in the middle of everything I have to remove all animations. So, if I use handler then I have to remove callbacks for every view. — A. Badakhshan, Oct 10 '17 at 07:51
then use `AnimatorSet` with an offset playing normal repeating animation - i think this should work — pskink, Oct 10 '17 at 07:57
ok so i checked that and it seems that you dont even need `AnimatorSet`: normal `ObjectAnimator` works just fine with a starting offset and some repeating count - it just delays at start and when reaping there is no delays between repetitions — pskink, Oct 10 '17 at 08:31
Sorry, I thought first that he is pointing to your first solution. I edited my question. — A. Badakhshan, Oct 10 '17 at 08:50
`ObjectAnimator repeat = ObjectAnimator.ofFloat(v, "rotation", 0, 360); repeat.setRepeatCount(4); repeat.setDuration(1000); repeat.setStartDelay(2000); repeat.start();` — pskink, Oct 10 '17 at 08:52

@pskink, It worked. So put an answer if you want so I can accept it. — A. Badakhshan, Oct 10 '17 at 09:15

If you are using VectorDrawable and AnimatedVectorDrawable in XML files in res/drawable folder and defined your animation in an objectAnimator file in res/animator folder then the startOffset delay works on the first occasion only not during repetitions. Repetitions are immediate. On the other hand if you want the animation to start with the delay everytime it repeats then I believe onAnimationEnd resetting works.
