public void scrollTo (int x, int y) 
Since: API Level 1 
Set the scrolled position of your view. This will cause a call to onScrollChanged(int, int, int, int) and the view will be invalidated. 

This version also clamps the scrolling to the bounds of our child.

Parameters
x  the x position to scroll to 
y  the y position to scroll to  
  */
