12. Dialogs
Dialogs demand attention and input from the user. They are useful for presenting a choice or important
information. In this chapter, you will add a dialog in which users can change the date of a crime.
Pressing the date button in CrimeFragment will present this dialog on Lollipop and later (Figure 12.1).

The dialog in Figure 12.1 is an instance of AlertDialog, a subclass of Dialog. AlertDialog is the all-
purpose Dialog subclass that you will use most often.
