Improving the To-do List App

If you're interested in expanding upon the demo app, or you just want some ideas for creating an app of your own, refer to the following feature list. The list is roughly ordered in increasing difficulty.

• Support configuration changes
  • Hint: Learn about the onSaveInstanceState method of the Activity class. You can also use the ViewModel class, though this is more difficult.
• Add more content to to the to-do list items
  • Hint: Learn about creating a custom ArrayAdapter
• Create an indicator for completed tasks e.g. a check box
• Support more comprehensive notes e.g. in a new activity when a list item is selected
• Create a trash bin to restore delete items
• Change the way that items are deleted e.g. swipe to dismiss
  • Hint: For swipe to dismiss, learn about the RecyclerView and ItemTouchHelper classes
• Support reordering of items e.g. drag and drop
  • Hint: For drag and drop, learn about the RecyclerView and ItemTouchHelper classes
• Support organization of the to-do list items e.g. separation into categories such as work, school, etc.
• Support persistence of the data
  • Hint: Learn about the Room Persistence Library if you want to save the data locally. Learn about a cloud database, such as Firebase's Cloud Firestore, if you want to be able to access the data across multiple devices.
