In this assignment, you need to design and extend a ToDoList app which
contains at least two views.
1. The Main view should contain [0.5 mark]:
• A ListView which displays all the saved ToDoItems, each ToDoItem consists of
ToDoItem title and the creation / last edited datetime. Clicking a ToDoItem will
switch to the “Edit/Add Item” view.
• An “ADD NEW” button. Once this button is clicked, the app will switch to the
“Edit/Add Item” view.
2. The “Edit/Add Item” view should contain [1 mark]:
• A Text field which allows user to type or edit the title of a ToDoItem to add or
update the ListView.
• A “Save” button used for adding new, or updating the title and datetime of
ToDoItem in the ListView:
o If adding a new item, capture both the item and creation datetime of the
ToDoItem. The creation datetime is the current system datetime.
o If updating an existing item, display both the item and creation/last edited
datetime of the ToDoItem. Upon saving, update the item and datetime with
the current system datetime.
• A “Cancel” button next to the “Save” button, used to close the Activity without
updating the ToDoItem. When this button is clicked, the app will pop up a dialog
that asks user: ”Are you sure to cancel this edit? Your unsaved edit will be
discarded if you click YES”.
Hint: You should customise the ListView and the adapter. Read the following tutorial, and
replace the current ArrayAdapter with your own defined Adapter class. Also replace the list
item layout “android.R.layout.simple_list_item_1” with your own layout.
