HorizontalScrollView And ScrollView

java.lang.Object
↳	android.view.View
	↳	android.view.ViewGroup
		↳	android.widget.FrameLayout
			↳	android.widget.HorizontalScrollView

Class Overview

---

Layout container for a view hierarchy that can be scrolled by the user, allowing it to be larger than the physical display. A 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. A child that is often used is a LinearLayout in a horizontal orientation, presenting a horizontal array of top-level items that the user can scroll through.

The TextView class also takes care of its own scrolling, so does not require a HorizontalScrollView, but using the two together is possible to achieve the effect of a text view within a larger container.

HorizontalScrollView only supports horizontal scrolling. For vertical scrolling, use either ScrollView orListView.

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.
