Challenge: More Dialogs
For an easy challenge, write another dialog fragment named TimePickerFragment that allows the user to select what time of day the crime occurred using a TimePicker widget. Add another button to CrimeFragment that will display a TimePickerFragment.
For a harder challenge, stay with a single button interface, but have that button display a dialog that offers the user a choice: change the time or change the date. Then fire up a second dialog when the user makes a selection.
