drawerlayout

I'm developing an application which uses the navigation drawer pattern (With DrawerLayout). Each click on a drawer's item, replaces the fragment in the main container. However, I'm not sure when is the right time to do the fragment transaction? When the drawer starts closing? Or after it is closed?
