As a User, I want to scroll through multiple stocks

[GurkomalSRao]

As a user, I want to be able to scroll through multiple stocks that have been added [SP: 10] [Priority: 1] [Risk: High]

Demo Scenario 1: User swipes horizontally to scroll through stocks added on main menu

Task Estimation (Hours) Task 1: Research how to add scroll bar to widget (.1h) Task 2: Discuss with assignee's (.5h) Task 3: Implement scroll feature (.5h) Task 4: Validate potential flaws i.e. infinite scrolling or scrolling with little to no stocks listed (1h) Task 5: Modify and review with assignee's (1.5h)

Sample of Demo

[Nick9500]

Experiencing difficulty refactoring code to a GridView/ListView to display stocks. Existing code was hardcoded using 5 or 10 TextView-based elements (depending on widget size) rather than a data structure holding stocks so scalability is very very bad in pre-existing code.

[GurkomalSRao]

All views and Data was hard coded. Implementing our own functionality, at this point, does not seem feasible.

Attempted the following procedures:

Scenario 1:

• Create an ArrayList that receives all rows of the widget (String Values)
• Create an Intent that is connected to Remote View Service
• Remote View Service calls Remote View Factory
• Remote View Factory creates the structured list using the ArrayList

Scenario 2:

• Create an ArrayList that receives all rows of the widget (String Values)
• Create an Intent
• Create a Pending Intent that will be sent to Remote Service
• Call the Pending Intent within Remote Service
• Remote View Service calls Remote View Factory and sends the pending intent values
• Remote View Factory creates the structured list using the values received

Scenario 3:

• Refactor entire view using a newly created AppProvider, Remote Service, RemoteFactory.

Scenarios 1 and 2 would not allow any connections from WidgetView and RemoteService (compilation errors) Scenario 3 not plausible due to intensive hard coding and class manipulation done by original creator of widget source code

Completely new widget view in progress.

[Nick9500]

Widget pulls stock information from another instance of original widget.

[Nick9500]

Left to do: -Make new widget layout standalone by allowing stocks to be set through new widget layout. IE. Pull up the Preferences Activity via button press, double tap, etc. -Find a way to format columns better than using string concatenation and spaces. -Write tests for new methods/functionality (if applicable)

[Nick9500]

Recommend taking another 4 story points in Sprint 3 to finish story. Original estimation was way underestimated considering Risk Level due to knowledge and lack of scalability of original app.

[Nick9500]

Story has been extended to Sprint 3 to finish as discussed in meeting on Feb. 12.

ListView widget is now standalone!

To demo: -Long press the home screen -Add any ministocks widget -Tap slightly below the widget to open preferences (Button to be added in future) -Stocks can be added/modified as usual via preferences
