Save Button

  • Click the save button to save all objects on the recyclerView

    • Left image
    • Category name
    • Cost
  • If the save button is not clicked even when navigating to the chart or calendar, the objects created will be lost

DataStructure & Data save/retrieval methods

  • The arraylist will be saved to SharedPreferences with Google Gson library
  • Shared preferences just stores primitive java type so it’s sufficient here
  • Can easily save and load the data
  • It’s like a built in serializer so it’s easy to use

​

  • So far the implementation of the app is meant for one day use, so the ArrayList is just fine.
  • Even if in the future, the date is added, unless it’s getting data from years and years, ArrayList is still fine too.

Pie Chart

  • When click on the create chart button a pie chart is created using the anyChart API
    • Downside runs on API 19+ only
  • Go through the objects and create two string with contains of the category names and the total cost per cateogry.

Missing features/Challenges

  • Implementing what I have for each day
    • The object item I have now is called exampleItem and I didn’t have enough time to add another variable called date into call since that would change for the loading and saving data
  • One of the challenge I had was making my own serializer and loading it on to the page
    • Overome: searched online and I found that people are using gson
  • Another Challenge was making the recycling view and having each object as a card
    • I did a lot of googling to figure that out
