Observe the MediatorLiveData given by ViewModel, and update RecyclerViewAdapter accordingly.

	mainViewModel = ViewModelProvider(activity!!).get(MainViewModel::class.java)

	// New observer
	mainViewModel.getAllData()?.observe(viewLifecycleOwner,
	Observer { subjectsAndRemindersPair ->
	view.sro_subject_list.adapter = SubjectRecyclerViewAdapter(
	subjectsAndRemindersPair.first,
	subjectsAndRemindersPair.second,
	listener)
	})

Methods inside ViewModel to grab two LiveData from repository and put them into one MediatorLiveData

	fun getSubjects(): LiveData<List<Subject>>? {
	return sroRepository.getSubjects()
	}

	fun getReminders(): LiveData<List<Reminder>>? {
	return sroRepository.getReminders()
	}

	fun getAllData(): CombinedSubjectReminders? {
	var ldSubjects = getSubjects()

Example of a MediatorLiveData class to handle two LiveDatas at once.

	import androidx.lifecycle.LiveData
	import androidx.lifecycle.MediatorLiveData


	// This class ia a MediatorLiveData created since I have two different sources of data:
	// - subjects table
	// - reminders table
	// Since they then become two separate LiveData, and I need both to fill in the data
	// on the main RecyclerView, then we're using a MediatorLiveData to grab both LiveData
	// and add them as sources, so that we can notify observers when any of the data gets

	super.onCreate(savedInstanceState)
	setContentView(R.layout.activity_main)

	// Instead of findViewById<TextView>(R.id.textView)
	textView.setText("Hello, world!")
