Todo 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: Rishwanth Senthilkumar
Time spent: 20 hours spent in total
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)
- 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)
- Tweak the style improving the UI / UX, play with colors, images or backgrounds
The following additional features are implemented:
- Using content providers to give abstraction to the data
- using alert dialogs in the case of delete operation
- sorting the todoitems using date and priority
- using loaders to do loading of data in the background.
Here's a walkthrough of implemented user stories:

As part of your pre-work submission, please reflect on the app and answer the following questions below:
Question 1: "What are your reactions to the Android app development platform so far? Compare and contrast Android's approach to layouts and user interfaces in past platforms you've used."
Answer: I enjoy developing android apps. Android approach is similar to webdevelopment, here using XML instead of HTML.
Question 2: "Take a moment to reflect on the ArrayAdapter used in your pre-work. How would you describe an adapter in this context and what is its function in Android? Why do you think the adapter is important? Explain the purpose of the convertView in the getView method of the ArrayAdapter."
Answer: I used cursoradapter in list view instead of array adapter, though i used array adapter for showing the list of items in the spinner. Listview and adapter is very important for recycling views which saves lot of memory usage when the list becomes very big. convertview in getview is the used old views which can be recycled with the new data to show the list to the users. This saves memory usage and good user experience.
Describe any challenges encountered while building the app.
Main challenge I encountered was using dialog fragement for dates and time picker.
