Horizontal Scroll View as a base layout for Grid

[prasad-1210]

I want to have Grid View as Horizontal Scroll View with scroll bar if over flow. As far as i understand, Right now i can control layout of each item but, I'm sure how to change complete layout to Horizontal layout. I want to have a single line Grid with Scroll and allow user to re arrange elements in single line grid.

If Grid view comes with columns and row configurable like, set no.of columns or rows to 2 or 3 that wold be fantastic.
