ScrollView and HorizontalScrollView in Android

ScrollView and HorizontalScrollView
ScrollView and HorizontalScrollView are layout container for a view hierarchy that can be scrolled vertically or horizontally by the user, allowing it to be larger than the physical display. A ScrollView/HorizontalScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll ; this child may itself be a layout manager with a complex hierarchy of objects.
