When set to true, forces column boundaries to appear in the same order as column indices. The default is true. See Android.Widget.GridLayout.ColumnOrderPreserved.

Must be a boolean value, either "true" or "false".

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.
