Android : How can I use ObjectAnimator parameters to adjust for all devices?

I want to use ObjectAnimator to move a textView in the Y axis.This code works but it is not suitable for every device because of the screen sizes.

   ObjectAnimator mover = ObjectAnimator.ofFloat(expand, "translationY", -250, 0);

How can I change the last two parameters?There are also similar questions there I tried these also but they don't work.
