Architecture

This AI Diary app uses MVVM architecture. There is also a Repository layer, which is for interacting with API calls or DB transactions.

// View
viewModel!!.diaryList.observe (this, Observer {
    // TODO
})

// ViewModel
private val diaryListState = MutableLiveData<List<Diary>>()
val diaryList: LiveData<List<Diary>> get() = diaryListState

diaryListState.value = repo.getDiarys() // get data from API and/or DB
