    from what i've understood you are trying to make circles that you are drawing randomly clickable by the user, well this is pretty easy actually first you have to save the random position of the new circle in an integer variable then make a condition that will be controlled through an onToutchEvent

    @Override
        public boolean onTouchEvent (MotionEvent event) {
    
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN : 
                    xPos = event.getX();
                    yPos = event.getY();
                    invalidate(); 
                    break;
            }
    
            return true;
    
        }
