The selector accepts the date format selected by the user, which means that you do not need to format it, since the user probably likes to see the format that he used most.
I just checked the HelloDatePicker tutorial, and on my phone I have a date in the format (dd / mm / yyyy), so the collector shows the same format; in the emulator I set the date in the format mm / dd / yyyy, so the collector displays the same.
According to this answer, there is no way to set the display format.
