Is it possible to get real time coordinates of an ImageView while it is in Translate animation?

Question

I have an image of a bullet in an ImageView that does Translate animation.

I need to show real time coordinates to show how far it is from target in real time.

You can use an ObjectAnimator (API 11+):

ImageView iv = (ImageView)findViewById(R.id.markerRed);

// Create animators for x and y axes
ObjectAnimator oax = ObjectAnimator.ofFloat(iv, "translationX", 0f, 100f);
ObjectAnimator oay = ObjectAnimator.ofFloat(iv, "translationY", 0f, 100f);
oax.setRepeatCount(Animation.INFINITE);
oay.setRepeatCount(Animation.INFINITE);

// Combine Animators and start them together
AnimatorSet set = new AnimatorSet();
set.setDuration(1000);
set.playTogether(oax, oay);
set.start();

Then fetch the animation values like this:

Log.e("TAG", "X: " + oax.getAnimatedValue() + " Y:" + oay.getAnimatedValue());

If you add these values to the initial ImageView's coordinates, you'll get the current location.
