Why Doesn't My FirebaseListAdapter Display Individual Items in Firebase-UI 3.1?

FirebaseListAdapter fails to display individual items in Firebase-Ui 3.1

Firebase-Ui 3.1 introduces some changes to its API, particularly for the FirebaseListAdapter. The original code used to construct the list adapter is no longer valid, resulting in the ListView displaying no data.

To resolve this issue, the code needs to be updated to comply with the new requirements:

FirebaseListOptions<ChatMessage> options = new FirebaseListOptions.Builder<ChatMessage>()
        .setQuery(FirebaseDatabase.getInstance().getReference("Lobbies").child(leaderID).child("Messages"), ChatMessage.class).setLayout(R.layout.message).build();

adapter = new FirebaseListAdapter<ChatMessage>(options) {
    @Override
    protected void populateView(View v, ChatMessage model, int position) {
        // Get references to the views of message.xml
        TextView messageText = v.findViewById(R.id.message_text);
        TextView messageUser = v.findViewById(R.id.message_user);
        TextView messageTime = v.findViewById(R.id.message_time);

        // Set their text
        messageText.setText(model.getMessageText());
        messageUser.setText(model.getMessageUser());

        // Format the date before showing it
        messageTime.setText(DateFormat.format("dd-MM-yyyy (HH:mm:ss)",
                model.getMessageTime()));
    }
};

Moreover, it is essential to start and stop listening to changes in the database to display the data and avoid memory leaks. This can be achieved by adding the following methods:

@Override
protected void onStart() {
    super.onStart();
    adapter.startListening();
}


@Override
protected void onStop() {
    super.onStop();
    adapter.stopListening();
}
