Question

I have two animation with different duration like below:
Anim 1:

    TranslateAnimation trans1 = new TranslateAnimation(0, 0, 0, 500);  
    trans1.setStartOffset(0);  
    trans1.setDuration(5000);  
    trans1.setFillAfter(true);  

Anim 2:

    TranslateAnimation trans2 = new TranslateAnimation(0, -100, -200, -200);  
    trans2.setDuration(200);  
    trans2.setRepeatCount(25);  
    trans2.setFillAfter(true);  

As you see these animation have different durations. I would like to animate Anim2 (duration 200) in loop 25 times during one time Anim1 (duration 5000) animation from Y: 0 to 500.

I’ve tried to do with AnimationSet and addAnimation but it doesn’t want to work.
Could You give me some tips how can I solve this problem?

My code:

AnimationSet rootSet = new AnimationSet(true);   
rootSet.setInterpolator(new AccelerateInterpolator());  
rootSet.setRepeatMode(Animation.INFINITE);  
rootSet.setRepeatCount(200);  
rootSet.setDuration(5000);  
rootSet.setFillAfter(true);  

    TranslateAnimation trans1 = new TranslateAnimation(0, 0, 0, 500);  
    trans1.setStartOffset(0);  
    trans1.setDuration(5000);  
    trans1.setFillAfter(true);  

rootSet.addAnimation(trans1);


AnimationSet rootSet2 = new AnimationSet(true);  
rootSet2.setInterpolator(new AccelerateInterpolator());  
rootSet2.setRepeatMode(Animation.INFINITE);  
rootSet2.setRepeatCount(200);  
rootSet2.setDuration(200);  

    TranslateAnimation trans2 = new TranslateAnimation(0, -100, -200, -200);  
    trans2.setDuration(200);
    trans2.setRepeatCount(25);
    trans2.setFillAfter(true);

rootSet2.addAnimation(trans2);  

rootSet.addAnimation(rootSet2);  

iv.startAnimation(rootSet);  

EDIT:
When I play only trans2 animation it repeats 25 times as I wanted (in horizontal way).
And additionally I would like this animation to animate (whole horizontal animation not only imageview) in vertical way (trans1).

I hope that this description will be clearer.

When I added these two animations in one AnimationSet the first animation doesnt work at all and imageview (not animationn) is translated linear to -200,500.

Now I see what you want to do. You probably are better of doing multiple animations – one for each “line”. Add an AnimationListener to know when the previous Animation ends (onAnimationEnd callback), jump down one line and go from right to left again.

They all basically are the same, just the fromYDelta and toYDelta values would change for each Animation.
