Re-Arranging icons inside application

I would like to know how to implement arranging of icons inside the application menu in andro开发者_开发知识库id? I can quote the example of Car view app in Nexus S, where we can move the icons after touching the icon for a while and then moving it. Similar to that in samsung android phones, where we can move the icons at our ease on the home screen. Any thoughts/suggestions ??
