Pre-work - MyToDo

MyToDo 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: Dianne Bautista

Time spent: 12 hours spent in total

User Stories

The following required functionality is completed:

• User can successfully add and remove items from the todo list
• 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.
• 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)
• Add support for selecting the priority of each todo item (and display in listview item)
• Tweak the style improving the UI / UX, play with colors, images or backgrounds

The following additional features are implemented:

• Add a splash_screen that fetches the list of items from the database before the TodoListActivity is loaded
• Sort todo items by date
• Add support for showing a "check mark" when a todo item is marked as "Done"
• Wrap the DatePickerDialog and AlertDialog in a DialogFragment to make them more re-usable

Video Walkthrough

Here's a walkthrough of implemented user stories:

Implementation Notes

• I didn't use a DialogFragment (instead of new Activity) for editing items. I created an activity called TodoInputActivity which was used for both adding a new item or editing a new item. The only difference is that the user input is populated when an item is being edited.
• I didn't pass the TodoItem as an extra when switching from one activity to another. Instead, this is stored in the TodoManager, which maintains the selected item and manages the persistent state of the item.

Notes

Describe any challenges encountered while building the app.

• Inconsistent behavior on different devices
  • Before using a DatePicker in the DateChooserDialogFragment, I was using a CalendarView. This works well on my Samsung Galaxy S6, but the app hangs when using Samsung Galaxy S3 and when the dialog finally shows up, the view looks compressed. As it turns out, I have to set the layout_width and layout_height to match_parent instead of wrap_content to get around this issue.
