Today's Lecture/Lab

• Project management
• By popular request, more about Lists

Project Management

• In software engineering course: requirements, design, implementation, testing
• In 10 weeks, there is no time to do it right
• If you want to build a ship, don't drum up the men to gather wood, divide the work, and give orders. Instead, teach them to yearn for the vast and endless sea. — Antoine de Saint Exupéry (Attributed)
• Inch pebbles, not milestones. They are done or not done.
• Many short meetings
• Research is good, but it should lead to tangible results quickly
• The wiki is your friend
• It is better to ask for forgiveness later than for permission now

Source and Documentation Repository

• Make a github account and let me know what it is
• Use the github wiki
• If you work on Cinequest, just clone the repo
• Everyone checks in all their code
• Everyone makes sure that the code builds on everyone's machine
• ...and on my machine
• There will be unit tests

Weekly Report

• Each team member keeps an individual report on the wiki
• Pretend you are a contractor. Log every hour.
• Just update the Wiki when you are done with a stretch of work
• Team lead keeps a list of each meeting, a list of open issues, a list of inch pebbles
• Meeting: Date/time/anyone missing
• Open issues. Anything that makes you nervous. Cross out closed items (<del> in Markdown)
• Inch-pebbles. Add responsible person. Cross out achieved items, add new items.

Lists with buttons etc.

• You can put any components into a list row
• Remember: Have separate layout XML for ListView and each row
• Row layout set with adapter
• Row layout can contain any components. Example: Cinequest listitem_titletimevenue.xml
• But when you have a focusable component (input text field, button, etc) inside, the item clicks no longer work. That's not a bug—not. One remedy: android:focusable="false" or maybe android:descendantFocusability="blocksDescendants" (haven't tried the latter).
• Need to attach listeners in getView method. Example: CinequestActivity.ScheduleListAdapter.getView

Sectioned Lists

• Long lists often have separate sections
• Example: A section for each letter, or for each day
• No direct API support, but lots of homegrown approaches
• Here, here, here, here, here
• Cinequest SeparatedListAdapter builds upon one of them.

Fast Scrolling

• Enabling (with android:fastScrollEnabled) causes "thumb control" to appear next to scrollbar
• Dragging the thumb does fast-scroll. As the thumb traverses the height of the window, all items are shown.
• Need to implement SectionIndexer
• Shows popup with section name (broken on emulator)
• See this blog

Miscellaneous List Features

• Can have special view for empty list
• Can have a header. Call addHeaderView before setting the adapter.
• Expensive to keep inflating all those list views. Remedy: Use view holder pattern
• Except, starting with ICS, there is a better way

Reading Before Next Class

• Read four news articles about Samsung. Below are two, and find two others.
• Samsung expected to widen smartphone lead over Apple this year
• Samsung's Market-Flooding Strategy May Not Work Much Longer

Lab

• Bring your laptop to the lab
• You will work with a buddy
• One of you writes code, the other types up answers
• Switch roles each lab
• Submit lab work to git
