Android: Thread.sleep( ) not working

In my android app, I want to apply an animation on some imageViews with implementing delay. When the 1st imageView is animated 50%, i want to start animation of the second imageView and goes on like this.

I used Thread.sleep() method for this. 

public void showImage() throws IOException, InterruptedException{
    final Animation anim = AnimationUtils.loadAnimation(Home.this,R.anim.myanimation);



    image_1.setImageUrl(links[0]); 
    image_2.setImageUrl(links[1]); 
    image_3.setImageUrl(links[2]);
    image_4.setImageUrl(links[3]);

    image_5.setImageUrl(links[4]); 
    image_6.setImageUrl(links[5]); 
    image_7.setImageUrl(links[0]); 
    image_8.setImageUrl(links[1]); 
    //System.out.println("me");

    image_1_layer.setAnimation(anim); 
    Thread.sleep(5000);
    image_2_layer.setAnimation(anim); 
    Thread.sleep(5000);
    image_3_layer.setAnimation(anim);
    Thread.sleep(5000);
     image_4_layer.setAnimation(anim); 
     Thread.sleep(5000);

     image_5_layer.setAnimation(anim);
     Thread.sleep(5000);
     image_6_layer.setAnimation(anim);
     Thread.sleep(5000);
     image_7_layer.setAnimation(anim);
     Thread.sleep(5000);
     image_8_layer.setAnimation(anim);
     Thread.sleep(5000);
}

But when it run the app, it delay before starting any animation and then paralally animate all the imageViews. how can I start to animate the next imageView after 5 seconds of the previous imageView's animation?

I called the above showImage() method from the override method onPostExecute().

Using Thread.sleep is an incorrect way of achieving what you want. You should take a look at the Animation class, specifically the setStartTime.

You can either construct different animation objects with different (compounded) start times and apply all of them to the views or you can listen to animation events using setAnimationListener
