1. Login Screen

a. onViewCreated

The code sets up an observer to watch for changes in a login and perform actions depending on the result of said login. If the result of the login (loginResult) is null, nothing is done. Otherwise, the progress bar is hidden and we check the status of the login result. If it has had an error, a message is shown. If the login is successful, the UI is updated with the user’s info, a message is shown saying “Login OK” and the user’s id is updated with the loginOK() method to match the new user’s id.

b. setOnClickListener

The code here listens for when the login button is clicked, and sets the progress bar to be visible, as well as attempts to log in with the entered username and password. It is inside a Fragment class because it allows the code inside to be more encpsulated and self-contained within an app, separate from an activity.

c. DataSourceHardcode

user_harcoded = if (username == "user1@uoc.com") {
    User(1, "Jane Doe")
} else {
    User(2, "John Doe")
}
