ScrollView

Scroll view supports only one child as in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects. A child that is often used is a Linear Layout in a vertical orientation, presenting a vertical array of top-level items that the user can scroll through.
> Scroll View supports only vertical scrolling.
> In ScrollView they cant support Listview placed as child.
