ScrollView

extends View

Class Overview

A ScrollView represents a view with scrollbars (vertical and/or horizontal).

Default properties

By default, ScrollView is a VerticalLayout vertically scrollable. Horizontal scroll can be added calling setHorizontalScroll(boolean). You change the type of Layout, by calling the setContent(Layout) method.

Cross Platform Considerations

Avoid setting MATCH_CONTENT for ListViews or ScrollViews at all times.
Avoid setting MATCH_PARENT for height of the ScrollView's content at all times.

The hierarchy of ScrollView is also concerned by this note. MATCH_CONTENT in the hierarchy could break down the ScrollView display.
