Want to start animation at a specific time, You can use the Animation.setStartTime() method and set it to View through the View.setAnimation(). method.

ImageView spaceshipImage = (ImageView) findViewById(R.id.spaceshipImage);Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(this, R.anim.hyperspace_jump);spaceshipImage.startAnimation(hyperspaceJumpAnimation);
