Notes on video lecture:
The Fragment Class
Notes taken by Edward Tanguay on July 1, 2014 (go to class or lectures)
Choose from these words to fill the blanks below:
appropriate, heuristics, vertical, larger, 3.0, activities, destroyed, hosting, view, hierarchy, hand, high, interface, visible, zero, right, use
•
fragments were added to Android        to better support interfaces for devices with              screens
•
some of the design                      that made sense for smaller phone display no longer work
•
example application: quote viewer
•
two activities
•
1. shows titles of Shakespeare plays
•
2. when title is selected, a quote from that play is shown
•
this is an                        interface for a phone
•
on a tablet, however, the display is not too          and wide
•
too much white space
•
uses little of the                  space
•
imposes a slow back-and-forth user experience since the user has to move his          so far
•
better layout for tablet:
•
quotes now get shown on           
•
single activity
•
two fragments
•
fragments
•
are hosted by                     
•
an activity can host          or more fragments
•
lifecycle of a fragment is tied to the lifecycle of the activity that is hosting it
•
a fragment is statically bound to its                activity
•
a fragment also has some of its own lifecycle callbacks
•
two states
•
resumed
•
fragment is visible in running activity
•
paused
•
another activity is in the foreground and has focus
•
containing activity is               
•
stopped
•
fragment is not visible
•
lifecycle callback statements
•
onAttach()
•
fragment is first attached to activity
•
onCreate() (not the same as the activity)
•
unlike in activity.onCreate(), you don't set up the user                    here, but in onCreateView()
•
onCreateView()
•
set up user interface
•
sets up and returns a          which contains the fragment's user interface
•
onActivityCreated()
•
fragment gets this call after its view has been installed in the activity's view                   
•
after fragment's user interface has been installed in the activity, its lifecycle is dependent on the life cycle of the activity
•
if the hosting activity is about to become visible, it will receive a call to its onStart() method, and the fragment will also receive a call to its onStart() method
•
same with onResume()
•
same with onPause()
•
same with onStop()
•
when activity is                   , fragment receives a call to onDestroyView()
•
clean up resources associated with the view
•
then when fragment is no longer in       , it receives a call to its onDestroy() method
•
when no longer attached to activity, it receives called to onDetach() where you might want to null out references to the hosting activity

Vocabulary:

heuristic, adj. refers to experience-based techniques for problem solving, learning, and discovery that give a solution which is not guaranteed to be optimal, e.g. where exhaustive search is impractical, heuristic methods are used to speed up the process of finding a satisfactory solution via mental shortcuts to ease the cognitive load of making a decision ⇒ "Some of the design heuristics that made sense for smaller phone displays no longer work on large tablet screens."
