Chapter 10 Using Fragment Arguments
Here CrimeListFragment creates an explicit intent that names the CrimeActivity class.
CrimeListFragment uses the getActivity() method to pass its hosting activity as the Context object
that the Intent constructor requires.
Run CriminalIntent. Press any list item, and you will see a new CrimeActivity hosting a
CrimeFragment (Figure 10.2).
Figure 10.2 A blank CrimeFragment
The CrimeFragment does not yet display the data for a specific Crime, because you have not told it
which Crime to display.
