how to save position of x and y coordinate

Question

I have a joystick that have an x and y coordinates and I want to move the Imageview to the position of the x and y coordinates but retaining its position and not going back to 0,0 again.I have already tried setting the x and y coordinates of the imageview by getting the coordinates of the joystick but the joystick is going back to 0,0 everytime I untouch the screen.

if(arg1.getAction() == MotionEvent.ACTION_DOWN
                        || move.getAction() == MotionEvent.ACTION_MOVE) {

                    attackImage.setX(arg1.getX());
                    attackImage.setY(arg1.getY());}
