ScrollView children width and height

The warning that Ben mentions states: ScrollView children must set their layout_width or layout_height attributes to wrap_content rather than fill_parent or match_parent in the scrolling dimension.

Why is this and why do we just need to change height to wrap_content and not both to wrap_content?

A ScrollView is supposed to fit a child bigger than itself and scroll vertically to let you see the whole thing. Setting the height of the content inside to match_parent, i.e., the height of the ScollView, defeats the purpose. match_parent for width is ok, and let's the child know how wide it can be. It the project, it lets the instructions/direction word wrap to the fixed width and only have to scroll vertically.
