This practice task is aimed at creating a note-taking application. To accomplish this task, you will use the Room and Navigation libraries. Your knowledge of LiveData and ViewModels will also come in handy at runtime.
Let's imagine that we need to implement a note-taking app.
- The app should have the possibility to store notes in the database.
- It should be possible to view, add, edit, and delete notes.
- Notes should contain a name, a date (the date of creation or the last update time), and the note text itself.
- For the items of the list, display only a name and a date. By tapping on the item of the list, open the details screen with all information about a note, and show buttons to edit or delete a note on the details screen.
- After editing or deleting a note, update the list of notes on the main screen.
- In the edit mode, it is impossible to change the name, so only the note text can be changed.
Create an app that will allow managing notes locally. You need to take the following steps:
- Create a database to store notes (use Room for it).
- Create a screen with the list of notes. Add navigation to the details screen.
- Add the details screen. There should be an option to edit or delete a note on the screen.
- After editing or removing notes, redirect to the notes list screen.
- For navigation between screens, use the Navigation library.
- Use LiveData and ViewModels to handle data loading and send them to the fragments.
