How to set a border to an object when animating it inside a Layout?

Question

Java

Inside ConstraintLayoutwith the name colo = findViewById(R.id.colo);there are several objects that are constantly in motion, for example:

button1 = ObjectAnimator.ofPropertyValuesHolder(pr1,
  PropertyValuesHolder.ofFloat("x", 0, 850),
  PropertyValuesHolder.ofFloat("y", 140, 1050));
    button1.setDuration(6000 +this.a);
    button1.setRepeatCount(ObjectAnimator.INFINITE);
    button1.setRepeatMode(ObjectAnimator.REVERSE);

How to set movement coordinates (X, Y) based on the edges of the layout itself? I tried various experiments in the form colo.getWidth(), but apparently I'm doing something wrong.
