Server Data is not fetching in Retrofit

Server Data is not fetching in Retrofit - android

I want to fetch some data from the server by using the retrofitlibrary on RecyclerView but the data is not showing on RecycleView. I read lots of answers but did not solve it yet so please solve my problem thank you in advance.
Below is my JSON Data
{
"item": [
{
"Item_Id": "1",
"Item_Name": "Item Name 1",
"Item_Description": "Item Name 1 Description",
"Item_Price": "330.00",
"Discount": "10",
"Item_Image": "http://192.168.1.5/easyshop/Items_Image/xyz.jpg",
"First_Name": "abc",
"Last_Name": "xyz",
"Mobile": "**********"
},
{
"Item_Id": "2",
"Item_Name": "Item Name 2",
"Item_Description": "Item Name 2 Description",
"Item_Price": "40.00",
"Discount": "30",
"Item_Image": "http://192.168.1.5/easyshop/Items_Image/xyz1.jpg",
"First_Name": "def",
"Last_Name": "uvw",
"Mobile": "**********"
}
]
}
API Client class where I have used the base URL, GSON and retrofit object
public class ApiClient {
public static final String BASE_URL = "http://192.168.1.5/easyshop/";
private static Retrofit retrofit = null;
public static Retrofit getClient() {
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(100, TimeUnit.SECONDS)
.readTimeout(100,TimeUnit.SECONDS)
.build();
Gson gson = new GsonBuilder()
.setLenient()
.create();
if (retrofit==null) {
retrofit = new Retrofit.Builder()

}
return retrofit;
}
}
Interface
public interface APIService {
#FormUrlEncoded
#POST("GetItem.php")
Call<ItemArray> getItem(#Field("Retailer_Id")int Retailer_Id);
}
When I put JSON data in www.jsonschema2pojo.org it generates two files which are following as below
public class ItemArray {
#SerializedName("item")

private List<ItemList> item = null;
public List<ItemList> getItem() {

}
public void setItemDescription(String itemDescription) { this.itemDescription = itemDescription; }
public String getItemPrice() {
return itemPrice;
}
public void setItemPrice(String itemPrice) {
this.itemPrice = itemPrice;
}
public String getDiscount() {
return discount;
}
public void setDiscount(String discount) {
this.discount = discount;
}
public String getItemImage() {
return itemImage;
}
public void setItemImage(String itemImage) {

}
private void initViews() {
recyclerView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(layoutManager);
getDataFromServer();
}
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<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.

Expected a string but was BEGIN_ARRAY- Gson

Hi I am trying to parse Json from this api https://restcountries.eu. But when i trie to parse the topLevelDomain i ve got the error: "E/Error: java.lang.IllegalStateException: Expected a string but was BEGIN_ARRAY at line 1 column 42 path $[0].topLevelDomain"
How can i fix it ?
Thanks in advance

}
#Override
public void onFailure(Call<List<ModelJsona>> call, Throwable t) {

}

topLevelDomain is an array, not String. You should map it as so:
public class ModelJsona {
private String flag;
private String name;
private String region;
private List<String> topLevelDomain;
...
}
If you need it to be Serializable use ArrayList instead.

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!

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();
}

Sorry, if it's quite long. I have to show all my code to make it clear. I really need your help guys. Thanks

Set adapter inside onComplete method:
void request(final ProductListRequest productListRequest) {
getApi().loadproductlist(productListRequest.getCode())
.observeOn(AndroidSchedulers.mainThread())
.subscribeOn(Schedulers.io())
.subscribe(new Observer<ProductListResponse>() {
#Override
public void onCompleted() {
rvView.setHasFixedSize(true);
layoutManager = new LinearLayoutManager(this);
rvView.setLayoutManager(layoutManager);
adapter = new ProductAdapter(context, list);
rvView.setAdapter(adapter);
}
#Override
public void onError(Throwable e) {
Timber.e(e.getLocalizedMessage());
}
#Override
public void onNext(ProductListResponse response) {
if (response != null) {
Intent intent = new Intent(ProductActivity.this, ProductList.class);
startActivity(intent);
}
}
});
}

how to use retrofit with wordpress json api

i tried retrofit with simple json response which have [ {},{},{},{},{},{},] array of objects which works but when i tried retrofit with status:
{"ok",count: 4,count_total: 4,pages: 1,posts: [{},{},{},{}] }
I came up with null results ..plz find the correct solution how do i Call the retrofit for correct result.
pojo class`
public class Categories {
#SerializedName("status")
private int status;
#SerializedName("id")
private int id;
#SerializedName("type")
private String type;
#SerializedName("title")
private String title;
#SerializedName("content")
private String content;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}
mainactivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final RecyclerView recyclerView = (RecyclerView) findViewById(R.id.movies_recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
ApiInterface apiService =
ApiClient.getClient().create(ApiInterface.class);
Call<List<Categories>> call = apiService.response();
call.enqueue(new Callback<List<Categories>>() {
#Override
public void onResponse(Call<List<Categories>> call, Response<List<Categories>> response) {
List<Categories> movies = response.body();
recyclerView
.setAdapter(new MoviesAdapter(movies,
R.layout.list_item_movie, getApplicationContext()));
}
#Override
public void onFailure(Call<List<Categories>> call, Throwable t) {
}
});
}
apiclient.java
public class ApiClient {
public static final String BASE_URL = "http://androidaura.com/health/api/get_recent_posts/";
private static Retrofit retrofit = null;
public static Retrofit getClient() {
if (retrofit==null) {
retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}

You should change your POJO to following:
Public class Model {
String status; // because "ok" is string not boolean
int count;
int count_total;
int pages;
List<Post> posts;
public class Post {
// add attribute of your old pojo
}
}
Also make sure your class attribute be same as Server response;
