TP4: Fragments

📝 Goal

The goal is to refactor the app by introducing Fragments.

Preparatory work:

• Copy everything from previous TP (except the README)

Then:

• Create a BookListFragment fragment
• Update its attributes and factory method (the one called newInstance) to handle a ArrayList<Book>
• Move the <RecyclerView> from the layout of MainActivity to the one of BookListFragment
• Do the same for all RecyclerView related logic

In MainActivity:

• Add a <ConstraintLayout> in the layout
• Add some code to create a BookListFragment fragment and display it

Then:

• Create a CreateBookFragment fragment, if you generate it you can keep only onCreateView function and discard everything else
• Move code and layout from CreateBookActivity to CreateBookFragment
• Create an interface BookCreator with a onBookCreated(book: Book)
• Use onAttach function to save a reference to the activity
• Implement BookCreator interface in MainActivity

🚀 Getting Started

• Start Android Studio
• Select Open an existing Android Studio project and pick this directory

That's it! You can code!
