I'm having problems with showing JSONArray data on the Fragment. I am verified my links, Strings etc. But on the Debug console my request showing correct. I am suspecting JSONArray request but i can't find any errors.
Please, help!

Sorry for my bad English.

notify you adapter after the for loop body and declare the adapter globally
for ( int i = 0; i < response.length(); i++) {
............
modelDBList.add(dblist);
}
if(dblist != null and dblist.size() > 0){
adapter.notifyDataSetChanged();
}

It looks like you didn't update list of modelDB's inside adapter after the parsing of a network call result.

java.lang.ClassCastException: android.view.ContextThemeWrapper cannot be cast to androidx.appcompat.app.AppCompatActivity
Here you are casting a context to an AppCompatActivity but actually Activity is not a Context
You have two options to solve this:
First option: Create a listener interface between the activity/fragment that holds the RecyclerView, implement it in that activity, and trigger its callback within the CardView onClickListener onClick() callback.
Second option: Change the constructor signature of the AdapterAttractionsPackageOffer adapter to accept a FragmentManager instance; save it as a class field like below, and reflect that on the instantiation of the adapter
public class AdapterAttractionsPackageOffer extends RecyclerView.Adapter<AdapterAttractionsPackageOffer.AttractionsViewHolderPackageOffer> {
public ArrayList<ItemPOA> mFavList;
private FragmentManager fragmentMgr;
public AdapterAttractionsPackageOffer(ArrayList<ItemPOA> favList, FragmentManager fManger) {
mFavList = favList;
fragmentMgr = fManger;
}
//......... suppressed code

#Override
public void onBindViewHolder(AttractionsViewHolderPackageOffer holder, int position) {

How to implement getItemViewType() for multiple layout in RecyclerView in a Movie Database app

I am creating a movie app using TMDB api, Retrofit, Gson and Glide. I have two recyclerView and two layout to inflate. But I am unable to inflate 2 layout in recyclerView adapter.
I have already implemented popular and upcoming movie list in 2 different recyclerView. But they are showing using 1 single layout. I want to inflate popular movies in one layout and upcoming movies in another layout. I can't set the condition for getItemViewType() method. How can I check for popular and upcoming movies list in getItemViewType() method and implement it on onCreateViewHolder() method of recyclerView.
MovieAdapter class:
public class MovieAdapter extends RecyclerView.Adapter<MovieAdapter.MovieViewHolder> {

I want to inflate 2 different layout "movie_list_item.xml" and "upcoming_movie_list_item.xml" in onCreateViewHolder() method.

With in your adapter class(MovieAdapter) create a new constructor and add extra params of Int or enum whatever simple for you i am just giving you simple example:-
public class MovieAdapter extends RecyclerView.Adapter<MovieAdapter.MovieViewHolder> {
private Context context;
private ArrayList<Movie> movieArrayList;
private int viewType;
public MovieAdapter(Context context, ArrayList < Movie > movieArrayList, int viewType) {
this.context = context;
this.movieArrayList = movieArrayList;
this.viewType=viewType;
}
#NonNull
#Override
public MovieViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view;
if (viewType == 1) {
//Popular movie layout
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.movie_list_item, parent, false);
} else {
//upcoming movie layout
view = LayoutInflater.from(parent.getContext()).inflate(R.layout.movie_list_item, parent, false);
}
return new MovieViewHolder(view);
}
#Override
public int getItemViewType(int position) {
if (viewType == 1)
return 1; //Popular Movie Layout
else
return 2; //Upcoming Movie Layout
// return super.getItemViewType(position);
}
#Override
// Set values to the list item components
public void onBindViewHolder(#NonNull MovieViewHolder holder, int position) {
holder.movieTitle.setText(movieArrayList.get(position).getOriginalTitle());
holder.rating.setText(String.valueOf(movieArrayList.get(position).getVoteAverage()));
String imagePath = "https://image.tmdb.org/t/p/w500" + movieArrayList.get(position).getPosterPath();
Glide.with(context)
.load(imagePath)
.placeholder(R.drawable.loading)
.into(holder.movieImage);
}
#Override
public int getItemCount() {
return movieArrayList == null ? 0 : movieArrayList.size();
}
public class MovieViewHolder extends RecyclerView.ViewHolder {
TextView movieTitle, rating;
ImageView movieImage;
public MovieViewHolder(#NonNull View itemView) {
super(itemView);
movieImage = itemView.findViewById(R.id.ivMovieImage);
movieTitle = itemView.findViewById(R.id.tvTitle);
rating = itemView.findViewById(R.id.tvRating);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION) {
Movie selectedMovie = movieArrayList.get(position);
Intent intent = new Intent(context, MovieActivity.class);
intent.putExtra("movie", selectedMovie);
context.startActivity(intent);
}
}
});
}
}
and within your activity change on this method only
private void showOnRecyclerView() {
recyclerViewPopular = findViewById(R.id.rvMovies);
recyclerViewUpcoming = findViewById(R.id.rvTopMovies);
RecyclerView.LayoutManager popularLayoutManager = new LinearLayoutManager(this);
RecyclerView.LayoutManager upcomingLayoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
recyclerViewUpcoming.setLayoutManager(upcomingLayoutManager);
recyclerViewPopular.setLayoutManager(popularLayoutManager);
movieAdapter = new MovieAdapter(this, popularMovie,1);
upcomingAdapter = new MovieAdapter(this, topRatedMovie,2);
if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
recyclerViewPopular.setLayoutManager(new GridLayoutManager(this, 2));
} else {
recyclerViewPopular.setLayoutManager(new GridLayoutManager(this, 4));
}
recyclerViewPopular.setItemAnimator(new DefaultItemAnimator());
recyclerViewUpcoming.setItemAnimator(new DefaultItemAnimator());
recyclerViewPopular.setAdapter(movieAdapter);
recyclerViewUpcoming.setAdapter(upcomingAdapter);
movieAdapter.notifyDataSetChanged();
upcomingAdapter.notifyDataSetChanged();
}

Cannot cast onItem clicklistener inside Fragment Class form Adapter Class

I have an Fragment with recycleview where I populate it with json items from internet.
It load fine and Next step I want to is open new Activity when any row is clicked. It works in activity, thus I modified the same code for fragment but for fragment it throws exception in line
mExampleAdapter.setOnItemClickListener(getActivity());
with errror setOnItemClickListener of refrence adatper cannot be applied to Fragment activty and thus when I change line to
(ExampleAdapter.OnItemClickListener)
and when i build and run . Then app crashes with error that Mainactivity which holds framgnet cannot be cast in to .ExampleAdapter$OnItemClickListener
Here is my whole Fragment class
public class Mynotes extends Fragment implements ExampleAdapter.OnItemClickListener{

replace getActivity with getContext when you work in fragment,
You can read more here
What is different between getContext and getActivity from Fragment in support library?

Your activity should implement ExampleAdapter.OnItemClickListener

And your activity set EditText Listener to this..!
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
#Override
public void afterTextChanged(Editable editable) {
adapter.getFilter().filter(charSequence.toString());
}
});
i hope it's helpful to you ..!

Implement addTextChangedListener() on your search EditText and as the text changes filter your list data and update MovieAdapter with filtered data.
check this post on how to update custom list adapter

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

JSONArray data won't show on Fragment - java

notify you adapter after the for loop body and declare the adapter globally for ( int i = 0; i < response.length(); i++) { ............ modelDBList.add(dblist); } if(dblist != null and dblist.size() > 0){ adapter.notifyDataSetChanged(); }

It looks like you didn't update list of modelDB's inside adapter after the parsing of a network call result.
