MutableSharedFlow is being re collected again and again

I have the following ViewModel and Fragment -
class HeroesViewModel(private val heroesRepository: HeroesRepository) : ViewModel() {
private val internalUiState = MutableStateFlow<UiState>(UiState.Initial)
val uiState = internalUiState.asLiveData()
private val internalUiAction = MutableSharedFlow<UiAction>(1).apply {
tryEmit(UiAction.GetSuggestedList)
}
val uiAction = internalUiAction.asLiveData()
private val externalUiEvent = MutableSharedFlow<UiEvent>(1)
private val uiEvent = externalUiEvent.asSharedFlow()
init {
observeUiEvents()
}
private fun observeUiEvents() = viewModelScope.launch {
uiEvent.collect { event ->
when (event) {
is UiEvent.ListItemClicked -> {
navigateToHeroDetails(event.heroModel)
}
is UiEvent.SearchTextChanged -> {
getHeroesByName(event.searchText)
}
}
}
}
private fun navigateToHeroDetails(heroModel: HeroesListModel) =
submitAction(UiAction.NavigateToHeroesDetails(heroModel))
private fun getHeroesByName(name: String) = viewModelScope.launch(Dispatchers.IO) {
when (val response = heroesRepository.getHeroesByNameWithSuggestions(name)) {
is NetworkResponse.Success -> {
internalUiState.emit(UiState.Data(response.body as List<HeroesListModel>))
}
is NetworkResponse.Error -> {
response.error.message?.let { message ->
internalUiState.emit(UiState.Error(message))
}
}
else -> {}
}
}
fun getSuggestedHeroesList() = viewModelScope.launch(Dispatchers.IO) {
when (val response = heroesRepository.getSuggestedHeroesList(true)) {
is NetworkResponse.Success -> {
submitState(UiState.Data(response.body as List<HeroesListModel>))
}
is NetworkResponse.Error -> {
response.error.message?.let { message ->
submitState(UiState.Error(message))
}
}
else -> {}
}
}
private fun submitAction(uiAction: UiAction) = internalUiAction.tryEmit(uiAction)
private fun submitState(uiState: UiState) = viewModelScope.launch {
internalUiState.emit(uiState)
}
fun submitEvent(uiEvent: UiEvent) = externalUiEvent.tryEmit(uiEvent)
sealed class UiEvent {
data class SearchTextChanged(val searchText: String) : UiEvent()
data class ListItemClicked(val heroModel: HeroesListModel) : UiEvent()
}
sealed class UiState {
data class Data(val modelsListResponse: List<BaseHeroListModel>) : UiState()
data class Error(val errorMessage: String) : UiState()
object Initial : UiState()
}
sealed class UiAction {
data class NavigateToHeroesDetails(val heroModel: HeroesListModel) : UiAction()
object GetSuggestedList : UiAction()
}
}
class DashboardFragment : Fragment() {
//Class Variables - UI
private lateinit var binding: FragmentDashboardBinding
//Class Variables - Dependency Injection
private val heroesViewModel = get<HeroesViewModel>()
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View {
binding = FragmentDashboardBinding.inflate(inflater, container, false)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
init()
observeUiState()
observeUiAction()
}
private fun observeUiAction() = heroesViewModel.uiAction.observe(viewLifecycleOwner) { action ->
when(action){
is HeroesViewModel.UiAction.GetSuggestedList -> {
getSuggestedHeroesList()
}
is HeroesViewModel.UiAction.NavigateToHeroesDetails -> {
navigateToHeroesDetails(action.heroModel)
}
}
}
private fun init() {
binding.heroesSearchView.setOnQueryTextListener(object : OnSearchViewOnlyTextChangedListener() {
override fun onQueryTextChange(newText: String?): Boolean {
if (newText.isNullOrEmpty()) return false
heroesViewModel.submitEvent(HeroesViewModel.UiEvent.SearchTextChanged(newText))
binding.progressBar.setVisiblyAsVisible()
return false
}
})
}
private fun observeUiState() = heroesViewModel.uiState.observe(viewLifecycleOwner) { uiAction ->
when (uiAction) {
is HeroesViewModel.UiState.Data -> {
showHeroesList(uiAction)
}
is HeroesViewModel.UiState.Error -> {
showGeneralError(uiAction)
}
HeroesViewModel.UiState.Initial -> Unit
}
}
private fun navigateToHeroesDetails(heroModel: HeroesListModel) =
findNavController().navigate(DashboardFragmentDirections.actionMainFragmentToHeroesDetailsFragment(heroModel))
private fun showHeroesList(result: HeroesViewModel.UiState.Data) {
binding.heroesList.setContent {
LazyColumn {
items(result.modelsListResponse.toList()) { model ->
if (model is HeroListSeparatorModel)
HeroesListSeparatorItem(model)
else if (model is HeroesListModel)
HeroesListItem(model) {
heroesViewModel.submitEvent(HeroesViewModel.UiEvent.ListItemClicked(model))
}
}
}
}
binding.progressBar.setVisiblyAsGone()
}
private fun showGeneralError(result: HeroesViewModel.UiState.Error) {
Toast.makeText(requireContext(), result.errorMessage, Toast.LENGTH_LONG).show()
binding.progressBar.setVisiblyAsGone()
}
private fun getSuggestedHeroesList() {
heroesViewModel.getSuggestedHeroesList()
binding.progressBar.setVisiblyAsVisible()
}
}
As you can see, I have the replayCache set to 1 in internalUiAction but the value keeps emitting itself. When I navigate using the navigateToHeroesDetails() method and go back using the navigation bar I immediately observe the last uiAction emitted value which is NavigateToHeroesDetails, causing me to navigate again and again to the heroes details screen. This is an endless loop of navigation.
As far as a hint for a solution, if I double tap the navigation 2 times quickly it does indeed go back to the first Fragment. Seems like I am missing something related to SharedFlow

Filtering a recyclerview list using map or switchmap

I've been trying to figure this out for 2 days now - I just can't seem to get it to work!
I'm using MVVM with a Repository pattern.
Could someone tell me what I'm doing wrong here?
I'm trying to filter the list to show characters who appeared in specific seasons
e.g any characters from season 2 would be displayed but characters who weren't in season 2 would be omitted from being displayed.
The season list is also from the api endpoint which is why I'm trying to filter it in the viewmodel.
Is this the right way to do this or is there a better/different way to do it ?
Here's my Fragment class
#AndroidEntryPoint
class CharactersFragment : Fragment(R.layout.fragment_character_list) {
private lateinit var binding: FragmentCharacterListBinding
private val recyclerViewAdapter = MyCharactersRecyclerViewAdapter()
private val viewModel: CharactersViewModel by viewModels()
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View {
binding = FragmentCharacterListBinding.inflate(inflater, container, false)
setHasOptionsMenu(true)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
showError()
setupRecyclerView()
navigateToDetails()
}
override fun onOptionsItemSelected(item: MenuItem) =
when (item.itemId) {
R.id.menu_filter -> {
showFilteringPopUpMenu()
true
}
else -> {
false
}
}
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
inflater.inflate(R.menu.characters_fragment_menu, menu)
val searchItem: MenuItem = menu.findItem(R.id.menu_item_search)
val searchView = searchItem.actionView as SearchView
searchView.apply {
setOnQueryTextListener(object : SearchView.OnQueryTextListener {
override fun onQueryTextSubmit(queryText: String): Boolean {
Log.d("MainActivity", "QueryTextSubmit: $queryText")
return false
}
override fun onQueryTextChange(queryText: String): Boolean {
Log.d("MainActivity", "QueryTextChange: $queryText")
recyclerViewAdapter.filter.filter(queryText)
return true
}
})
}
}
private fun navigateToDetails() {
recyclerViewAdapter.setOnItemClickListener {
val action =
CharactersFragmentDirections.actionCharactersFragmentToCharacterDetailsFragment(it)
findNavController().navigate(action)
}
}
private fun setupRecyclerView() {
binding.list.apply {
layoutManager =
StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL)
adapter = recyclerViewAdapter
viewModel.characters.observe(viewLifecycleOwner) {
it?.let {
recyclerViewAdapter.updateList(it)
Log.d("TAG", "onViewCreated: ${it.size}")
}
}
}
}
private fun showError() {
viewModel.spinner.observe(viewLifecycleOwner) { value ->
value.let { show ->
binding.spinner.visibility = if (show) View.VISIBLE else View.GONE
}
}
viewModel.errorText.observe(viewLifecycleOwner) { text ->
text?.let {
binding.errorTextView.apply {
this.text = text
visibility = View.VISIBLE
}
binding.list.visibility = View.GONE
viewModel.onErrorTextShown()
}
}
}
private fun showFilteringPopUpMenu() {
val view = activity?.findViewById<View>(R.id.menu_filter) ?: return
PopupMenu(requireContext(), view).run {
menuInflater.inflate(R.menu.filter_seasons, menu)
setOnMenuItemClickListener {
when (it.itemId) {
R.id.one -> {
viewModel.season.value = FilterSeasons.SEASON_ONE
Toast.makeText(requireContext(), "Season One", Toast.LENGTH_SHORT)
.show()
}
R.id.two -> {
viewModel.season.value = FilterSeasons.SEASON_TWO
Toast.makeText(requireContext(), "Season Two", Toast.LENGTH_SHORT)
.show()
}
R.id.three -> {
viewModel.season.value = FilterSeasons.SEASON_THREE
Toast.makeText(requireContext(), "Season Three", Toast.LENGTH_SHORT)
.show()
}
R.id.four -> {
viewModel.season.value = FilterSeasons.SEASON_FOUR
Toast.makeText(requireContext(), "Season Four", Toast.LENGTH_SHORT)
.show()
}
R.id.five -> {
viewModel.season.value = FilterSeasons.SEASON_FIVE
Toast.makeText(requireContext(), "Season Five", Toast.LENGTH_SHORT)
.show()
}
else -> {
viewModel.season.value = FilterSeasons.ALL_SEASONS
Toast.makeText(requireContext(), "All Seasons", Toast.LENGTH_SHORT)
.show()
}
}
true
}
show()
}
}
}
And here's my ViewModel
#HiltViewModel
class CharactersViewModel #Inject constructor(
private val repository: Repository
) : ViewModel() {
private val _spinner = MutableLiveData<Boolean>(false)
val spinner: LiveData<Boolean> = _spinner
val season = MutableLiveData<FilterSeasons>()
private val _errorText = MutableLiveData<String?>()
val errorText: LiveData<String?> = _errorText
private val _characters = MutableLiveData<List<BreakingBadCharacterItem>?>()
val characters: LiveData<List<BreakingBadCharacterItem>?> =
_characters.map { seasons ->
when (season.value) {
ALL_SEASONS -> {
seasons
}
SEASON_ONE -> seasons?.filter {
it.appearance.any { it == 1 }
}
SEASON_TWO -> seasons?.filter {
it.appearance.any { it == 2 }
}
SEASON_THREE -> seasons?.filter {
it.appearance.any { it == 3 }
}
SEASON_FOUR -> seasons?.filter {
it.appearance.any { it == 4 }
}
SEASON_FIVE -> seasons?.filter {
it.appearance.any { it == 5 }
}
else -> {
seasons
}
}
}
init {
getAllCharacters()
season.value = ALL_SEASONS
}
private fun getAllCharacters() =
viewModelScope.launch {
try {
_spinner.postValue(true)
val response = repository.loadBBCharacters()
_characters.postValue(response)
} catch (error: BreakingError) {
_errorText.postValue(error.message)
} finally {
_spinner.postValue(false)
}
}
fun onErrorTextShown() {
_errorText.value = null
}
}
I also have an Enum class
enum class FilterSeasons {
ALL_SEASONS,
SEASON_ONE,
SEASON_TWO,
SEASON_THREE,
SEASON_FOUR,
SEASON_FIVE
}

In your menuItemListener you are modifying the viewmodel.season bit you're not actually listening/observing to any changes to this value.
I would recommend a custom setter here (not sure it needs to be liveData as it's not being observed) :
val season: FilterSeasons = FilterSeasons.All
set(value) {
field = value
filterCharacterBySeason(value)
}
And then abstract the filtering you are doing in the character LiveData into itls own method filterCharacterBySeason(season: FilterSeason)

Handle search results after configuration change MVVM

I am building a movie app based on "The Movie DB". My app has only one activity with a recyclerview and one search action button (SearchView).
As soon as the app starts,the recyclerview filled with popularMovies list.
When I search for a movie I get the results and everything is fine,but when I rotate the screen I get the popularMovies list and not my search results.
Now I know the reason,its happening because in onCreate I have initMoviesRecyclerView() that fill the recyclerview with popularMovies.
My question is how can I keep the search results without filling the recyclerview with popularMovies ? How can I do this the correct way ?
This is the Repository Class:
class MainRepository {
//MutableLiveData
private val popularMoviesMutableLiveData = MutableLiveData<List<Movie>>()
private val searchAfterMutableLiveData = MutableLiveData<List<Movie>>()
// API
private val apiService : GetFromApi = APIService.retrofitClientRequest
private val apiKey = "NOT"
fun getPopularMoviesList() : MutableLiveData<List<Movie>>{
apiService.getPopularMovies(apiKey,1)?.enqueue(object : Callback<MovieListResult?> {
override fun onResponse(
call: Call<MovieListResult?>,
response: Response<MovieListResult?>
) {
if (response.isSuccessful){
popularMoviesMutableLiveData.value = response.body()?.moviesResults
Log.e("MovieListResults","Result: ${popularMoviesMutableLiveData.value}")
}
}
override fun onFailure(call: Call<MovieListResult?>, t: Throwable) {
Log.e("MovieListResults","Failed: ${t.message}")
}
})
return popularMoviesMutableLiveData
}
fun searchAfter(searchAfter : String) : MutableLiveData<List<Movie>>{
apiService.searchAfter(apiKey,searchAfter)?.enqueue(object : Callback<MovieListResult?> {
override fun onResponse(
call: Call<MovieListResult?>,
response: Response<MovieListResult?>
) {
if (response.isSuccessful){
searchAfterMutableLiveData.value = response.body()?.moviesResults
Log.e("SearchMovieListResults","Result: ${searchAfterMutableLiveData.value}")
}
}
override fun onFailure(call: Call<MovieListResult?>, t: Throwable) {
Log.e("SearchMovieListResults","Failed: ${t.message}")
}
})
return searchAfterMutableLiveData
}
}
This is the viewModel class:
class MainViewModel : ViewModel(){
//Repository
private val mainRepository = MainRepository()
//MutableLiveData
var popularMoviesMutableLiveData = MutableLiveData<List<Movie>>()
var searchAfterMutableLiveData = MutableLiveData<List<Movie>>()
//The Main Movie List
var mainMovieList = listOf<Movie>()
fun getPopularMovies() : LiveData<List<Movie>>{
popularMoviesMutableLiveData = mainRepository.getPopularMoviesList()
popularMoviesMutableLiveData.value = mainMovieList
return popularMoviesMutableLiveData
}
fun getMovieBySearch(searchAfter : String) : LiveData<List<Movie>>{
searchAfterMutableLiveData = mainRepository.searchAfter(searchAfter)
searchAfterMutableLiveData.value = mainMovieList
return searchAfterMutableLiveData
}
}
This is the MainActivity class:
class MainActivity : AppCompatActivity() {
//ViewModel
private val mainViewModel : MainViewModel by viewModels()
// Views
private lateinit var mainRecyclerView : RecyclerView
private lateinit var mainAdapter : MainRecyclerViewAdapter
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
initMoviesRecyclerView()
}
private fun initMoviesRecyclerView() {
mainRecyclerView = findViewById(R.id.mainRecyclerView)
mainRecyclerView.setHasFixedSize(true)
mainRecyclerView.layoutManager = GridLayoutManager(this,1)
mainViewModel.getPopularMovies().observe(this, object : Observer<List<Movie>?> {
override fun onChanged(newList: List<Movie>?) {
if (newList != null) {
mainViewModel.mainMovieList = newList
mainAdapter = MainRecyclerViewAdapter(mainViewModel.mainMovieList)
mainRecyclerView.adapter = mainAdapter
}
}
})
}
override fun onCreateOptionsMenu(menu: Menu): Boolean {
menuInflater.inflate(R.menu.main_menu,menu)
val searchView = menu.findItem(R.id.menu_search_movie).actionView as androidx.appcompat.widget.SearchView
searchView.queryHint = "Search By Name,Actor .."
searchView.setOnQueryTextListener(object : androidx.appcompat.widget.SearchView.OnQueryTextListener {
override fun onQueryTextSubmit(whileTextChange: String?): Boolean {
//Clear SearchView
searchView.isIconified = true
searchView.setQuery("", false)
searchView.onActionViewCollapsed()
mainViewModel.getMovieBySearch(whileTextChange.toString()).observe(this#MainActivity,object : Observer<List<Movie>?> {
override fun onChanged(newList: List<Movie>?) {
if (newList != null) {
mainViewModel.mainMovieList = newList
mainAdapter.changeCurrentList(mainViewModel.mainMovieList)
}
}
})
return false
}
override fun onQueryTextChange(whileTextChange: String?): Boolean {
Log.e("onQueryTextChange","Text: $whileTextChange")
return false
}
})
return true
}
}
Thank you!

I don't see where you actually populate the data inside the ViewModel. But it all looked good.
This line is a bit suspicious:
mainViewModel.mainMovieList = newList
You should not update the ViewModel from the View lifeCycle. Also, you should not update the ViewModel during the observe call.

So after sometime I manage to work around it with a simple solution:
I created a function in the viewModel,to check if the search list value is null:
fun startFromSearch(): Boolean {
return searchAfterMutableLiveData.value != null
}
After that I made an if statement in the initMoviesRecyclerView(), and that's it!
private fun initMoviesRecyclerView() {
mainRecyclerView = findViewById(R.id.mainRecyclerView)
mainRecyclerView.setHasFixedSize(true)
mainRecyclerView.layoutManager = GridLayoutManager(this,1)
mainAdapter = MainRecyclerViewAdapter(mainViewModel.mainMovieList,this)
mainRecyclerView.adapter = mainAdapter
if (!mainViewModel.startFromSearch()){
mainViewModel.getPopularMovies(1).observe(this, object : Observer<List<Movie>?> {
override fun onChanged(newList: List<Movie>?) {
if (newList != null) {
mainAdapter = MainRecyclerViewAdapter(newList,this#MainActivity)
mainRecyclerView.adapter = mainAdapter
}
}
})
}
}

Jetpack Composable doesn't react to changes

I've been trying to follow the only good example with support that I could find, but in my case, it doesn't work.
I have a ViewModel that talks to a #Model in Composable, and changes a loading: Bool according to a MutableLiveData<Boolean> but it doesn't recompose.
class LoaderViewModel : ViewModel() {
val loadingLiveData = MutableLiveData<Boolean>(false)
fun fetch() {
viewModelScope.launch {
val flow = flowOf("result")
.onStart {
loadingLiveData.value = true
delay(2000)
}
.onCompletion {
loadingLiveData.value = false
}
.collect {
// Do something with the result
}
}
}
}
class LoaderFragment : Fragment() {
private val viewModel: LoaderViewModel by viewModel()
#Model
class ActivityLoadingState(var loading: Boolean = false)
private val activityLoadingState = ActivityLoadingState()
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return FrameLayout(context ?: return null).apply {
layoutParams = FrameLayout.LayoutParams(MATCH_PARENT, MATCH_PARENT)
setContent {
Loader()
}
}
}
#Composable
fun Loader() = MaterialTheme {
val loadingModel = activityLoadingState
Container {
Center {
if (loadingModel.loading) {
CircularProgressIndicator(
color = Color(0xFFFF0000)
)
} else {
Container { }
}
}
}
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
subscribeUI()
viewModel.fetch()
}
private fun subscribeUI() {
viewModel.loadingLiveData.observe(viewLifecycleOwner) {
activityLoadingState.loading = it
}
}
}

What I am doing, is to have Flows in my ViewModel, and use function collectAsState() whitin composables.

Initialization of a fragment causes the animation lag

While writing an Android app, I encountered a problem with a stuttering animation. I use AHBottomNavigation for navigation, FragNav is for swapping fragments and FlexibleAdapter for RecyclerView.
The application is built from one activity and five fragments. When I try to switch to the first fragment in the application, the BottomNavigation animation freez for a moment. It looks very unsightly. The second time I choose the same fragment, everything works smoothly. It seems to me that it is the fault to initialize the views in the fragment, but I have no idea how to do it differently.

After a few days, I managed to solve the problem by updating the SDK to version 28. RecyclerView no longer causes animation jams when inflating
