add Views to ScrollView before childs/content

Hi, I've a ScrollView (calendar) with "layout" property set to "horizontal", the content is an array of Views (days of this month).

When the user scrolls the ScrollView until the end, I push more Views (days of the next month) to the ScrollView (calendar).

But when the user scrolls to the beginning of the ScrollView (calendar), how do I insert another array of Views (days of the previous month) before all the ScrollView (calendar) children/content?
