while Google clearly points out a standard way to do this
No, they do not.
They have a whole page about this in the Design section: Grid Lists.
They have material in the "Design" section, for which the Android SDK does not have a ready-made implementation. Other examples include a box , some of the gestures , and section headings in lists .
Is their documentation wrong?
This is the design documentation. In this case, it is not βwrongβ to have a design that requires horizontal scrolling of the GridView . The mere fact that the Android SDK does not provide one thing - at least at the time of this writing - does not prevent someone from creating it.
What does this page link to?
Grid.
