How to create a ListView with draggable items?

I was looking for a ListPreference in which a user can reorder items from a list. Elements will be drag and drop and can be reordered by the user.

I saw this in my regular ROM (and I'm pretty sure I saw it in Cyanogenmod) for QuickPanel. Here is a screenshot to get this idea:

I know how I can create custom ListView items and set an icon to indicate that items are being dragged, but I don't know how to drag them, and change the order accordingly. As for saving them in the settings, I found this one that can be easily implemented.
