android studio MVVM doesn't store date or display it

Sorry for bothering you guys, but I've following CodingInFlow's MVVM and everything went well until reached the the 7th video, I've created two Activities: MainActivity with a RecyclerView that displays a fake database as per MVVM and a Floating Action button and MainActivity2, whenever I move to MainActivity2 and enter some data and move back to MainActivity, I see that no item have been added to the RecyclerView but the Toasts work.
Ps: I'm new to stackoverflow so pardon me
Here are my Files:

I've tried to the best of my ability and read through these files multiple but nothing seems to be wrong to me(I'm still a novice).
Thanks in advance

You are nowhere telling the adapter that a new item has been added to the list therefore recycler view does not update. Try doing this,
public class MainActivity<O> extends AppCompatActivity {
private ActivityMainBinding mainBinding;
private NoteViewModel viewModel;
private List<Note> mList;
private NoteAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mainBinding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(mainBinding.getRoot());
viewModel =new ViewModelProvider(this).get(NoteViewModel.class);
adapter = new NoteAdapter();
mainBinding.recyclerView.setAdapter(adapter);
mainBinding.recyclerView.setLayoutManager(new LinearLayoutManager(this));
mainBinding.recyclerView.setHasFixedSize(true);
viewModel.getAllNotes().observe(this, this::setList);
ActivityResultLauncher<Intent> resultLauncher =registerForActivityResult(new ActivityResultContracts.StartActivityForResult(),
result -> {
if(result.getResultCode() == Activity.RESULT_OK){
String title =result.getData().getStringExtra(MainActivity2.EXTRA_TITLE_NOTE);
String description =result.getData().getStringExtra(MainActivity2.EXTRA_DESCRIPTION_NOTE);
int priority = result.getData().getIntExtra(MainActivity2.EXTRA_PRIORITY_NOTE, 1);
Note note = new Note(title, description, priority);
viewModel.insertNote(note);
mList.add(note);
adapter.setList(mList);
Toast.makeText(this, "Note Saved", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Note not saved", Toast.LENGTH_SHORT).show();
}
});
mainBinding.addFab.setOnClickListener(v -> {
resultLauncher.launch(new Intent(MainActivity.this, MainActivity2.class));
});
}
private void setList(List<Note> list){
mList = list;
if (adapter != null){
adapter.setList(list);
}
}

MVVM with Hilt,RxJava 3,Retrofit, Live Data and View Binding

I currently get stock on this part. I want to display simple data from GSON and I practice using MVVM structure and with Hilt and "RxJava".
This is my "View Model" and I don't know what to do.(This is my first time using this structure and dependencies.)
At my "getTip()" function under my View Model how can i transfer the data from "tipsModel" to arraylist and if i did something wrong at my codes.
public class TipsViewModel extends ViewModel {
private static final String TAG = "TipsViewModel";
private Repository repository;
private MutableLiveData<ArrayList<TipsModel>> tipsList = new MutableLiveData<>();
#ViewModelInject
public TipsViewModel(Repository repository){
this.repository = repository;
}
public MutableLiveData<ArrayList<TipsModel>> getTipsList(){
return tipsList;
}
public void getTips(){
repository.getTips()
.subscribeOn(Schedulers.io())
.map(new Function<TipsModel, ArrayList<TipsModel>>() {
#Override
public ArrayList<TipsModel> apply(TipsModel tipsModel) throws Throwable {
// What i have to put here to transfer the data from "tipsModel" to my ArrayList.
return null;
}
})
.observeOn(AndroidSchedulers.mainThread())
.subscribe(result -> tipsList.setValue(result),
error -> Log.e(TAG,"getTips: "+error.getMessage()));
}
}
This is my Repository
public class Repository {
private TipsApiService apiService;
#Inject
public Repository(TipsApiService apiService){
this.apiService = apiService;
}
public Observable<TipsModel> getTips(){
return apiService.getTips();
}
}
And this is my Model. it a simple model.
public class TipsModel {
private Integer id;
private String gameName;
private String gameMenu;
private String subtitle;
private String description;
private Object image;
public TipsModel(Integer id, String gameName, String gameMenu, String subtitle, String description, Object image) {
this.id = id;
this.gameName = gameName;
this.gameMenu = gameMenu;
this.subtitle = subtitle;
this.description = description;
this.image = image;
}
public Integer getId() {
return id;
}
public String getGameName() {
return gameName;
}
public String getGameMenu() {
return gameMenu;
}
public String getSubtitle() {
return subtitle;
}
public String getDescription() {
return description;
}
public Object getImage() {
return image;
}
public void setId(Integer id) {
this.id = id;
}
public void setGameName(String gameName) {
this.gameName = gameName;
}
public void setGameMenu(String gameMenu) {
this.gameMenu = gameMenu;
}
public void setSubtitle(String subtitle) {
this.subtitle = subtitle;
}
public void setDescription(String description) {
this.description = description;
}
public void setImage(Object image) {
this.image = image;
}
}
This is my Code on my fragment
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
binding = ActivityTipsViewBinding.inflate(inflater,container,false);
return binding.getRoot();
}
#Override
public void onViewCreated(#Nonnull View view, #Nullable Bundle savedInstanceState){
super.onViewCreated(view, savedInstanceState);
viewModel = new ViewModelProvider(this).get(TipsViewModel.class);
initRecyclerView();
observeData();
viewModel.getTips();
}
private void observeData(){
viewModel.getTipsList().observe(getViewLifecycleOwner(), new Observer<ArrayList<TipsModel>>() {
#Override
public void onChanged(ArrayList<TipsModel> tipsModels) {
Log.e(TAG,"onChanged: "+ tipsModels.size());
tipsAdapter.updateList(tipsModels);
}
});
}
private void initRecyclerView(){
binding.tipsRecyclerview.setLayoutManager(new LinearLayoutManager((getContext())));
tipsAdapter = new TipsAdapter(getContext(),tipsModels);
binding.tipsRecyclerview.setAdapter(tipsAdapter);
}
}

Receiving null Parcelable object Android

I'm trying to pass an object from my RecyclerView adapter to a fragment using parcelable. However when I try to receive the data, the bundle is null. I've looked at other examples, but I can't see where I'm going wrong.
Parcelable class
public class Country extends BaseObservable implements Parcelable {
#SerializedName("name")
#Expose
private String name;
#SerializedName("snippet")
#Expose
private String snippet;
#SerializedName("country_id")
#Expose
private String countryId;
#SerializedName("id")
#Expose
private String id;
#SerializedName("coordinates")
#Expose
private Coordinates coordinates;
#SerializedName("images")
#Expose
private List<CountryImage> images;
protected Country(Parcel in) {
name = in.readString();
snippet = in.readString();
}
public static final Creator<Country> CREATOR = new Creator<Country>() {
#Override
public Country createFromParcel(Parcel in) {
return new Country(in);
}
#Override
public Country[] newArray(int size) {
return new Country[size];
}
};
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeString(snippet);
}
#Override
public int describeContents() {
return 0;
}
#Bindable
public String getCountryId() {
return countryId;
}
public void setCountryId(String countryId) {
this.countryId = countryId;
notifyPropertyChanged(BR.countryId);
}
#Bindable
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
notifyPropertyChanged(BR.id);
}
#Bindable
public Coordinates getCoordinates() {
return coordinates;
}
public void setCoordinates(Coordinates coordinates) {
this.coordinates = coordinates;
notifyPropertyChanged(BR.coordinates);
}
#Bindable
public List<CountryImage> getImages() {
return images;
}
public void setImages(List<CountryImage> images) {
this.images = images;
notifyPropertyChanged(BR.images);
}
#Bindable
public String getSnippet() {
return snippet;
}
public void setSnippet(String snippet) {
this.snippet = snippet;
notifyPropertyChanged(BR.snippet);
}
#Bindable
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
notifyPropertyChanged(BR.name);
}
}
RetrofitAdapter.java
public class RetrofitAdapter extends RecyclerView.Adapter<RetrofitAdapter.MyViewHolder> implements CustomClickListener {
private List<Country> cities;
private CustomClickListener customClickListener;
private View view;
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
RetroItemBinding retroItemBinding =
DataBindingUtil.inflate(LayoutInflater.from(viewGroup.getContext()),
R.layout.retro_item, viewGroup, false);
view = viewGroup;
return new MyViewHolder(retroItemBinding);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder myViewHolder, int i) {
myViewHolder.bindTo(cities.get(i));
myViewHolder.retroItemBinding.setItemClickListener(this);
}
#Override
public int getItemCount() {
if (cities != null) {
return cities.size();
} else {
return 0;
}
}
public void setCityList(ArrayList<Country> cities) {
this.cities = cities;
notifyDataSetChanged();
}
class MyViewHolder extends RecyclerView.ViewHolder {
private RetroItemBinding retroItemBinding;
public MyViewHolder(#NonNull RetroItemBinding retroItemBinding) {
super(retroItemBinding.getRoot());
this.retroItemBinding = retroItemBinding;
}
void bindTo(Country country) {
retroItemBinding.setVariable(BR.city, country);
retroItemBinding.setVariable(BR.itemClickListener, customClickListener);
retroItemBinding.executePendingBindings();
}
}
public void cardClicked(Country country) {
CountryFragment countryFragment = new CountryFragment();
Bundle bundle = new Bundle();
bundle.putParcelable("Country", country);
countryFragment.setArguments(bundle);
((FragmentActivity) view.getContext()).getSupportFragmentManager().beginTransaction()
.replace(R.id.frag_container, new CountryFragment())
.commit();
}
}
Where I receive attempt to receive the data in CountryFragment.java
Country country;
Bundle bundle = this.getArguments();
if (bundle != null) {
country = bundle.getParcelable("Country");
}

.replace(R.id.frag_container, new CountryFragment())
should be
.replace(R.id.frag_container, countryFragment)
You are creating a second instance instead of passing the one you set the arguments on.

I am beginner in android Retrofit2 API call.
How to fetch items and set in recycler view .I think am not getting how to set items to the adapter class.
please help me out with this.
I have tried all possible ways to solve but not able to find any solution regarding this.

You have error with your models. They aren't properly configured. Please see this tutorial for a better understanding of retrofit and recyclerview.

picasso android image not loading

I am trying to get images from an API, and I have written code but images are not loading in emulator
Main activity
public class MainActivity extends ListActivity {
List<Flower> flowerList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final RestAdapter restadapter = new RestAdapter.Builder().setEndpoint("http://services.hanselandpetal.com").build();
api flowerapi = restadapter.create(api.class);
flowerapi.getData(new Callback<List<Flower>>() {
#Override
public void success(List<Flower> flowers, Response response) {
flowerList = flowers;
adapter adapt = new adapter(getApplicationContext(),R.layout.item_file,flowerList);
setListAdapter(adapt);
}
#Override
public void failure(RetrofitError error) {
Toast.makeText(getApplicationContext(),"Failed",Toast.LENGTH_SHORT).show();
}
});
}
In package model I have flower class
public class Flower {
private int productId;
private String name;
private String category;
private String instructions;
private double price;
private String photo;
private Bitmap bitmap;
public Flower() {
}
public Bitmap getBitmap() {
return bitmap;
}
public void setBitmap(Bitmap bitmap) {
this.bitmap = bitmap;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
public String getInstructions() {
return instructions;
}
public void setInstructions(String instructions) {
this.instructions = instructions;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhoto() {
return photo;
}
public void setPhoto(String photo) {
this.photo = photo;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public int getProductId() {
return productId;
}
public void setProductId(int productId) {
this.productId = productId;
}
}
In network package I have api java class
public interface api {
#GET("/feeds/flowers.jason")
public void getData(Callback<List<Flower>>response);
}
And then I have adaptor java class
public class adapter extends ArrayAdapter<Flower> {
String url="http://services.hanselandpetal.com/photos/";
private Context context;
private List<Flower> flowerList;
public adapter(Context context, int resource, List<Flower> objects) {
super(context, resource, objects);
this.context = context;
this.flowerList = objects;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.item_file,parent,false);
Flower flower = flowerList.get(position);
TextView tv = (TextView) view.findViewById(R.id.name);
tv.setText(flower.getName());
ImageView img = (ImageView) view.findViewById(R.id.img);
Picasso.with(getContext()).load(url+flower.getPhoto()).resize(100,100).into(img);
return view;
}
}
I am getting nothing on emulator and it says it failed. Is the fault in emulator.
I have included internet permission in manifest.

Might be blowing up on your #GET annotation param "/feeds/flowers.jason"
try ".json"
