Are you using the right model for mapping your response? Should it be:
DriverRequestModel driverRequestModel = response.body();

Server Data is not fetching in Retrofit

recyclerView.setAdapter(adapter);
}
}
#Override
public void onFailure(Call<ItemArray> call, Throwable t) {
Log.d("onFailure", t.toString());
}
});
}
}

You need to change your ApiServices Interface like this
public interface APIService {
#FormUrlEncoded
#POST("GetItem.php")
Call<ItemArray> getItem(#Field("Retailer_Id")int Retailer_Id);
}
Then in your Activity update the calling method
public void getDataFromServer() {
int i = 1;
APIService service = ApiClient.getClient().create(APIService.class);
Call<ItemArray> userCall = service.getItem(i);
userCall.enqueue(new Callback<ItemArray>() {
#RequiresApi(api = Build.VERSION_CODES.KITKAT)
#Override
public void onResponse(Call<ItemArray> call, Response<ItemArray> response) {
if(response.isSuccessful()){
progressBar.setVisibility(View.GONE);
data = response.body().getItem();
adapter = new Item_Card_Adapter(data);
recyclerView.setAdapter(adapter);
}
}
#Override
public void onFailure(Call<List<ItemList>> call, Throwable t) {
Log.d("onFailure", t.toString());
}
});
}
Since your api response contain the "list" inside a Json object. You need a class that has a List variable. So retrofit will parse the response to ItemArray successfully
Update
The demo code link https://github.com/Siddharth-Dev/RetrofitDemo
This has your code and a working API code too.

Resources$NotFoundException When calling a Rest API using RetroFit 2

I am calling a REST Api with RetroFit 2 and trying to display it with a RecyclerView but for some reason I am getting a Resources$NotFoundException.
The JSON generated That i want to read and display in a RecyclerView is:
{
"generated_at": "2018-05-31T12:10:29+00:00",
"schema": "http:\/\/schemas.sportradar.com\/bsa\/soccer\/v1\/json\/endpoints\/soccer\/tournament_standings.json",
"tournament": {
"id": "sr:tournament:17",
"name": "Premier League",
"sport": {
"id": "sr:sport:1",
"name": "Soccer"
},
"category": {
"id": "sr:category:1",
"name": "England",
"country_code": "ENG"
},
"current_season": {
"id": "sr:season:40942",
"name": "Premier League 17\/18",
"start_date": "2017-08-11",
"end_date": "2018-05-14",
"year": "17\/18"
}
},
"season": {
"id": "sr:season:40942",
"name": "Premier League 17\/18",
"start_date": "2017-08-11",
"end_date": "2018-05-14",
"year": "17\/18",

},
"standings": [{

So I created a Response which is :

}
public String getSchema() {
return mSchema;
}
public void setSchema(String schema) {
mSchema = schema;
}
public List<Standings> getStandings() {

}
The Response has a List of Standings, The standings POJO has a list of groups:
public class Standings {
#SerializedName("groups")
#Expose
private List<Group> mGroup;
public List<Group> getGroup() {
return mGroup;
}
public void setGroup(List<Group> group) {
mGroup = group;
}
The Groups POJO has a list of TeamStandings:
public class Group {
#SerializedName("team_standings")
#Expose
private List<TeamStandings> mTeamStandings;
public List<TeamStandings> getTeamStandings() {
return mTeamStandings;
}
public void setTeamStandings(List<TeamStandings> teamStandings) {

This exception come because you set integer value in textview so you should be do type casting of String .
For Example
you doing
mTxtView.setText(mList.get(position).getMETHOD_WHICH_RETURN_INT())
you should be do
mTxtView.setText(""+mList.get(position).getMETHOD_WHICH_RETURN_INT())
You should be
holder.teamRank.setText(""+mStandings.get(position).getGroup().get(position)
.getTeamStandings().get(position).getRank());
holder.teamPlayed.setText(""+mStandings.get(position).getGroup().get(position)
.getTeamStandings().get(position).getPlayed());
holder.teamWon.setText(""+mStandings.get(position).getGroup().get(position)
.getTeamStandings().get(position).getWin());
holder.teamDraw.setText(mStandings.get(position).getGroup().get(position)
.getTeamStandings().get(position).getDraw());
holder.teamLose.setText(""+mStandings.get(position).getGroup().get(position)
.getTeamStandings().get(position).getLose());
holder.teamFor.setText(""+mStandings.get(position).getGroup().get(position)
.getTeamStandings().get(position).getGoalsFor());
holder.teamAgainst.setText(""+mStandings.get(position).getGroup().get(position)

How to populate recyclerview with compex json data using retrofit?

please advise. I have a complex json object which I get requesting to openweathermap API using Retrofit and GSONConverterFactory. I have a trouble requesting forecast for 5 days, I can't populate my Recyclerview with the data, something goes wrong. I can't get what should I write in the onResponse method of Retrofit callback.
Retrofit requests are all with code 200 and message OK. So trouble is not in this area.
Thank you in advance!
Here is structure of Json object
WeatherData is a root Object which I get parsing my Json, please find the code below. All the code for it (as well as for other POJO's is imported from jsonschema2pojo:
public class WeatherData {
#SerializedName("coord")
#Expose
private Coord coord;
#SerializedName("weather")
#Expose
private List<Weather> weather = null;
#SerializedName("base")
#Expose
private String base;
#SerializedName("main")
#Expose
private Main main;
#SerializedName("visibility")
#Expose
private Integer visibility;
#SerializedName("wind")
#Expose
private Wind wind;
#SerializedName("clouds")
#Expose
private Clouds clouds;
#SerializedName("dt")
#Expose
private Long dt;
#SerializedName("sys")
#Expose
private Sys sys;
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("name")
#Expose
private String name;
#SerializedName("cod")
#Expose
private Integer cod;
public Coord getCoord() {
return coord;
}
public void setCoord(Coord coord) {
this.coord = coord;
}
public List<Weather> getWeather() {
return weather;
}
public void setWeather(List<Weather> weather) {
this.weather = weather;
}
public String getBase() {

}
public void setBase(String base) {
this.base = base;
}
public Main getMain() {
return main;
}
public void setMain(Main main) {
this.main = main;
}
public Integer getVisibility() {
return visibility;
}
public void setVisibility(Integer visibility) {
this.visibility = visibility;
}
public Wind getWind() {
return wind;
}
public void setWind(Wind wind) {
this.wind = wind;
}
public Clouds getClouds() {
return clouds;
}
public void setClouds(Clouds clouds) {
this.clouds = clouds;
}
public Long getDt() {
return dt;
}
public void setDt(Long dt) {
this.dt = dt;
}
public Sys getSys() {
return sys;
}
public void setSys(Sys sys) {
this.sys = sys;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getCod() {

Here is my RecyclerView.Adapter
public class Forecast5DaysAdapter extends RecyclerView.Adapter<Forecast5DaysAdapter.ForecastHolder> {
List<WeatherData> mWeatherDataList;
public static class ForecastHolder extends RecyclerView.ViewHolder {
public TextView dateOnDate;
public ImageView weatherOnDate;
public TextView tempOnDate;
public TextView windSpeedOnDate;
public ForecastHolder(View view) {
super(view);
dateOnDate = (TextView) view.findViewById(R.id.dateOnDate);
windSpeedOnDate = (TextView) view.findViewById(R.id.windSpeedOnDate);
tempOnDate = (TextView) view.findViewById(R.id.tempOnDate);
weatherOnDate = (ImageView) view.findViewById(R.id.imageOnDate);
}
}
public Forecast5DaysAdapter(List<WeatherData> mWeatherDataList) {
this.mWeatherDataList = mWeatherDataList;
}
#Override
public ForecastHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.forecast_card, parent, false);
final ForecastHolder forecastHolder = new ForecastHolder(view);
return forecastHolder;
}
#Override
public void onBindViewHolder(ForecastHolder holder, int position) {
//FILLING THE CARDS IN RECYCLERVIEW WITH INFORMATION
holder.dateOnDate.setText(mWeatherDataList.get(position).getDt().toString());
holder.tempOnDate.setText(mWeatherDataList.get(position).getMain().getTemp().toString());
holder.windSpeedOnDate.setText(mWeatherDataList.get(position).getWind().getSpeed().toString());
Picasso.with(holder.weatherOnDate.getContext()).load("http://openweathermap.org/img/w/" + mWeatherDataList.get(position).getWeather().get(position).getIcon() + ".png").into(holder.weatherOnDate);
}
#Override
public int getItemCount() {
return 0;
}
Here is the class I want to display the Recyclerview
public class Forecast5Days extends AppCompatActivity {
private static final String API_KEY = "HERE IS THE KEY";
private RecyclerView forecastRecycler;
private ArrayList<WeatherData> mWeatherData;
private Forecast5DaysAdapter forecast5DaysAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_forecast_5_days);
forecastRecycler = (RecyclerView) findViewById(R.id.forecast_5_daysRecycler);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
forecastRecycler.setLayoutManager(layoutManager);
final Forecast5DaysAdapter forecast5DaysAdapter = new Forecast5DaysAdapter(mWeatherData);
forecastRecycler.setAdapter(forecast5DaysAdapter);
Intent intent = getIntent();
final String cityName = intent.getStringExtra("cityName");
if (!cityName.isEmpty()) {
Call<WeatherData> call = RetrofitBuilderHelper.weatherAPI.getForecast5Days(cityName, "ru", "metric", API_KEY);
call.enqueue(new Callback<WeatherData>() {
#Override
public void onResponse(Call<WeatherData> call, Response<WeatherData> response) {
//????????????????
}
#Override
public void onFailure(Call<WeatherData> call, Throwable t) {
Toast toast = Toast.makeText(Forecast5Days.this, "Something went wrong with request", Toast.LENGTH_LONG);
toast.show();
}
});
} else {
Toast toast = Toast.makeText(Forecast5Days.this, "Something went wrong with intent", Toast.LENGTH_LONG);
toast.show();
}
}

Your onResponse should be like this
call.enqueue(new Callback<WeatherData>() {
#Override
public void onResponse(Call<WeatherData> call, Response<WeatherData> response) {
if(response.isSuccessful() && response.body != null) {
WeatherData data = response.body();
}
}
#Override
public void onFailure(Call<WeatherData> call, Throwable t) {
Toast toast = Toast.makeText(Forecast5Days.this, "Something went wrong with request", Toast.LENGTH_LONG);
toast.show();
}
});
Also your Call is Call<WeatherData> which will give you a single object. If you want a list of objects your call should be Call<List<WeatherData>>
I think you are looking to pass Weatherinstead of WeatherData so your onResponse should look like
call.enqueue(new Callback<WeatherData>() {
#Override
public void onResponse(Call<WeatherData> call, Response<WeatherData> response) {
if(response.isSuccessful() && response.body != null) {
WeatherData data = response.body();
List<Weather> weatherList = data.getWeatherList();
//Pass this list to your adapter
}
}
#Override
public void onFailure(Call<WeatherData> call, Throwable t) {
Toast toast = Toast.makeText(Forecast5Days.this, "Something went wrong with request", Toast.LENGTH_LONG);
toast.show();
}
});

Your JSON return is a List not only a Single WeatherData Object.
So all you should have to do is a cange of the Expected return value.
Try this:
Call<List<WeatherData>> call = RetrofitBuilderHelper.weatherAPI.getForecast5Days(cityName, "ru", "metric", API_KEY);
call.enqueue(new Callback<List<WeatherData>>() {
#Override
public void onResponse(Call<List<WeatherData>> call, Response<List<WeatherData>> response) {
forecastRecycler.weatherList = response.body();
forecastRecycler.notifyDatasetChanged();
}
