ToDoList

Pre-work - To Do List

To Do List is an android app that allows building a todo list and basic todo items management functionality including adding new items, editing and deleting an existing item.

Submitted by: Colby Sato

Time spent: 10 hours spent in total

User Stories

The following required functionality is completed:

• [X] User can successfully add and remove items from the todo list
• [X] User can tap a todo item in the list and bring up an edit screen for the todo item and then have any changes to the text reflected in the todo list.
• [X] User can persist todo items and retrieve them properly on app restart

The following optional features are implemented:

• [ ] Persist the todo items into SQLite instead of a text file
• [ ] Improve style of the todo items in the list using a custom adapter
• [ ] Add support for completion due dates for todo items (and display within listview item)
• [ ] Use a DialogFragment instead of new Activity for editing items
• [ ] Add support for selecting the priority of each todo item (and display in listview item)
• [X] Tweak the style improving the UI / UX, play with colors, images or backgrounds. ** I changed the color to green.

The following additional features are implemented:

• [X] Following Nielson's Heuristic of visibility of system status, I provided a dialog box

Notes

I faced several challenges while programming this application

• I misunderstood how scoping worked for variables. Ex. In the editItemActivity.java file, I received the position with intents in the onCreate method, but didn't realize I needed to call it again in the submit method.
• Calling the wrong id/item. Ex. etNewItem vs lvItems
• I misunderstood how to make a long-click listener for the list. I tried to put a long-click listener in the activity_edit_item.xml file instead of the MainActivity.java file.
• I tried to set a new adapter view when removing and inserting items into the list.

Approach

Roadblocks were faced, but I solved them by doing the following

• Asked "What is the goal?" and "What do I think I am doing?"
• Tested components to find what was working/broken.
• Read CodePath documentation, paying attention to key terms.
• If I didn't understand a term in the documentation, I'd read more background documentation to learn how things like intents and actions worked.
