ScrollView

⇒ In Android, a ScrollView is a view group that is used to make vertically scrollable views.

A scroll view contains a single direct child only.

In order to place multiple views in the scroll view, one needs to make a view group(like LinearLayout) as a direct child and then we can define many views inside it.

A ScrollView supports Vertical scrolling only, so in order to create a horizontally scrollable view, HorizontalScrollView is used.
