Homework 3 - Dumb Notes

1 Homework 3 - Dumb Notes Due Date: 2/14/19 by 11:59pm For this homework you will use Fragments, Intent filters, and a custom ArrayAdapter to build a simple note-taking app. The app provides functionality to add and edit notes, view a note, and display a list of all notes, but it does not save the notes into persistent storage. SUBMISSION INSTRUCTIONS Submit through Canvas CONFIGURATION Version - Your app should work on Android or higher Archive - You can use any archive you want (zip, tar, bz2, ) Package Name - edu.fsu.cs.mobile.hw3 OVERVIEW You will create two activities: MainActivity and EditNoteActivity You will create two fragments: NotesListFragment and ViewNoteFragment You will implement a custom ArrayAdapter: MyNoteArrayAdapter You will implement a POJO class: MyNote MyNote A class containing the following fields: title, timestamp, and body of the note This class must implement the Parcelable interface MainActivity Contains the two Fragments: NotesListFragment and ViewNoteFragment Initially displays the NotesListFragment Starts EditNoteActivity when the edit button is clicked

2 NotesListFragment The default view in MainActivity when the app first starts Displays the list of current MyNotes The ListView utilizes the custom MyNoteArrayAdapter as the adapter Since this app does not save the MyNotes to a database, the NotesListFragment will initially display an empty list, but you can provide a default list of MyNotes for testing. When an item in the list is clicked, the clicked MyNote should be displayed in ViewNoteFragment It also contains an add button, which when clicked starts the EditNotesActivity MyNoteArrayAdapter A custom adapter to bind a MyNote object to the a custom row layout Each row should display only the MyNote s title and timestamp You will need to implement at least the Constructor and the getview method ViewNoteFragment This fragment displays all of the MyNote data (title, timestamp, and body of the note) when an item is clicked in the NotesListFragment Upon hitting the back button, the app should return back to the NotesListFragment (hint: use the Fragment back stack) It contains an edit button, which when clicked passes the MyNote data to the EditNoteActivity EditNoteActivity Contains a form to create or edit a MyNote Contains two EditTexts: one to enter the title of the note, one to enter the body of the note Contains a save button, which when clicked performs the form validation, saves the current form data to a MyNote object using the current Date as the timestamp, and returns the MyNote object back to MainActivity which adds or replaces it in the array of MyNotes This Activity has an intent-filter with the following action: edu.fsu.cs.mobile.hw3.edit_note The intent-filter allows MainActivity or other apps to launch this activity for the specific action as described in class When launched by MainActivity without passing a MyNote, the form should be initially empty When launched by MainActivity with a MyNote, the form should be filled with the MyNote data

3 GRADING You cannot get bonus points if your assignment is late Correct implementation of MyNote that implements Parcelable Correct implementation of MainActivity Correct implementation of NotesListFragment Correct implementation of MyNoteArrayAdapter Correct implementation of ViewNoteFragment Correct implementation of EditNoteActivity that has the required intent-filter Bonus Complete one or more of the following tasks for the opportunity to earn an additional 10 points on your assignment 1. Have your app support Landscape Mode. 2. Add a separate action to EditNoteActivity for new notes. EditNoteActivity must handle the two actions separately 3. Add extra editing features to the EditNoteActivity such as changing font and color 4. Add a delete option to the NotesListFragment to delete a MyNote from the list 5. If you have a different idea that requires extra work, me about it and I will let you know if you can get a check-plus.

4 EXAMPLE App first loaded. The NotesListFragment is initially empty

5 The Add Note button is clicked launching an empty EditNoteActivity.

6 The Save button is clicked passing the MyNote back to MainActivity. The ViewNotesFragment now displays the newly added MyNote.

7 The first MyNote is clicked in the ListView, displaying it in ViewNoteFragment.

8 A second note has been created and clicked in the list, which is now displayed in ViewNoteFragment.

9 The Edit Note button was clicked passing the MyNote to EditNoteActivity. The form is completed with the current MyNote data.

10 The chores MyNote was modified and saved, passing the modified MyNote back to MainActivity. Notice that the NotesListFragment updated the Chores note instead of adding a new entry. Also notice that the timestamp has been updated with the newest modification time.
