Resizing view using onTouchListener

Question

Hi I am creating an application that would simply resize a view when I start dragging a button designated for resizing.

Layout to be resized is declared as: resizeAbleLayout and the button for dragging to resize that layout is declared as: btnResize

I have been able to resize the view but when I finished resizing the view, and start to resize it again it does not start to resize from the size that I left it.

My question is that how would I be able to save the last resized position of the view and smoothly resize it without shinking suddenly? :D

This is my code used for btnResize:

  btnResize.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            int x=(int)event.getX();
            int y=(int)event.getY();
                switch (event.getAction()){
                    case MotionEvent.ACTION_MOVE:
                        resizeAbleLayout.getLayoutParams().width = x;
                        resizeAbleLayout.getLayoutParams().height = y;
                        resizeAbleLayout.requestLayout();
                        break;
                }
            return true;
        }
    });

Thanks in advance for any help! :D

try using the += or -= not to use =:

switch (event.getAction()){
     case MotionEvent.ACTION_MOVE:
     resizeAbleLayout.getLayoutParams().width += x/Math.abs(x);
     resizeAbleLayout.getLayoutParams().height += y/Math.abs(y);
     resizeAbleLayout.requestLayout();
     break;
}
