Tip:
Parsing JSON is cumbersome and error-prone process if we do it manually. You can use jsonschema2pojo to parse your JSON for you within seconds.
Thank you.

You have some String objects expected:
String threeWay;
String doubleChance;
String goalGoal;
String halfTime;
String bookingPts
But your JSON says that all of them are arrays.

Parsing nested JSON with Retrofit library into a RecyclerView: Having a load data error

I'm a newbie in the Android development an am trying to parse complex JSON structure with the help of rertofit library from the http://api.tvmaze.com/search/shows?q=girls. But my project fails in loading data. I suppose that the problem is in the GSON model, but I'm in complete bewilderment what's exactly wrong.
I need to fetch only image and title
I have already included the internet permission in the manifest

I build my model class for fetching image and title, because i need only htese two items:
public class Image:
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Image {
#SerializedName("medium")
#Expose
private String medium;
#SerializedName("original")
#Expose
private String original;
public String getMedium() {
return medium;
}
public void setMedium(String medium) {
this.medium = medium;
}
public String getOriginal() {
return original;
}
public void setOriginal(String original) {
this.original = original;
}
}
public class Movie:
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Movie {
#SerializedName("name")
#Expose
private String name;
#SerializedName("image")
#Expose
private Image image;
public String getTitle() {
return name;
}
public void setTitle(String name) {
this.name = name;
}
public Image getImageUrl() {
return image;
}
public void setImageUrl(Image image) {
this.image = image;
}
}
A recyclerview adapter for those items:
public class MovieAdapter extends RecyclerView.Adapter<MovieAdapter.MyViewHolder> implements Filterable {

public void setMovieList(Context context,final List<Movie> movieList){

return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(MovieAdapter.MyViewHolder holder, int position) {
holder.title.setText(movieListFiltered.get(position).getTitle());
GlideApp.with(context).load(movieList.get(position).getImageUrl()).listener(new RequestListener() {
#Override
public boolean onLoadFailed(#Nullable GlideException e, Object model, Target target, boolean isFirstResource) {
// Log the GlideException here (locally or with a remote logging framework):
Log.e(TAG, "Load failed", e);
// You can also log the individual causes:
for (Throwable t : e.getRootCauses()) {
Log.e(TAG, "Caused by", t);
}
// Or, to log all root causes locally, you can use the built in helper method:
e.logRootCauses(TAG);
return false; // Allow calling onLoadFailed on the Target.
}
#Override
public boolean onResourceReady(Object resource, Object model, Target target, DataSource dataSource, boolean isFirstResource) {
// Log successes here or use DataSource to keep track of cache hits and misses.
return false; // Allow calling onResourceReady on the Target.
}
}).into(holder.image);

Thanks in advance for any help

The fields "name" and "image" that you are trying to parse are nested in a JSON object "show". You need to parse this field as well.
public interface ApiInterface {
#GET("search/shows?q=girls")
Call <List<MovieResponse>> getMovies();
}
Create a new Java object
public class MovieResponse {
#SerializedName("show")
#Expose
private Movie show;
public Movie getShow() {
return show;
}
}

RecyclerView not showing parsed GSON data

I've gone through a few questions on here and I'm absolutely stuck as to how to proceed. I am parsing data using GSON and I have added the results to my recyclerview in addition to adding the notifydatachange to the adapter and yet my recycler view is still empty. My logcat shows nothing wrong and is receiving information from the server. Can someone let me know what I have done incorrectly? My RecyclerView adapter seems ok and I think I added the necessary codes to my fragment.

and here is my LogCat:
ksburneytwo.weathertest E/GetWeatherAync: Response code:200
ksburneytwo.weathertest E/response: java.io.BufferedReader#3d54b14
ksburneytwo.weathertest E/something: 40
ksburneytwo.weathertest E/GetWeatherAync: populate UI recycler view with gson converted data

I figured out what was happening. The postexecute was sending it to the listener.aftersearch. It was there that the results needed to be sent to the recyclerview in the form of items.addAll(results). The recyclerview now loads.

Change Fragment dynamically

I have two tabs according to the number of category items (Mutton, Sea food) created dynamically.
In MenumainActivity I'm able to store Mutton items in ArrayList named listitemsAll and Sea food items in ArrayList named listitemsAll1 by doing this if (cat == 1)....
MenumainActivity:
public void onSuccess(String response) {
JSONObject obj = new JSONObject(response);
if (obj.getBoolean("status")) { 9
JSONObject hotels = obj.getJSONObject("Menu");
JSONArray items = hotels.getJSONArray("Items");
for (int j = 0; j < items.length(); j++) {
JSONObject hotel = items.getJSONObject(j);
categoryname = hotel.getString("name");
categoryid = hotel.getString("id");
hotelmenu = hotel.getJSONArray(categoryname);
listitems = new ArrayList<Menuclass>();
listitems1 = new ArrayList<Menuclass>();
for (int i = 0; i < hotelmenu.length(); i++) {
JSONObject menuitems = hotelmenu.getJSONObject(i);
itemname = menuitems.getString("name");
itemsprice = menuitems.getString("price");
itemtype = menuitems.getString("veg");
final int itemtypeint = Integer.parseInt(itemtype);
cat = Integer.parseInt(categoryid);
if (cat == 1) {
if (itemtypeint == 0) {
listitems.add(new Menuclass(itemname, itemsprice, R.drawable.nonveg));
}
else {
listitems.add(new Menuclass(itemname, itemsprice, R.drawable.vegicon));
}
else if (cat == 2) {
if (itemtypeint == 0) {
listitems1.add(new Menuclass(itemname, itemsprice, R.drawable.nonveg));
}
else {
listitems1.add(new Menuclass(itemname, itemsprice, R.drawable.vegicon));
}
}
}
listitemsAll.addAll(listitems);
listitemsAll.addAll(listitems1);
tabLayout.addTab(tabLayout.newTab().setText((categoryname)));
ViewPagerAdapter1 adapter = new ViewPagerAdapter1(getSupportFragmentManager(),items);
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new

Once you have changed the JSON to

You can use http://www.jsonschema2pojo.org/ and paste your JSON object to create 4 Java classes as
public class Menuclass {
#SerializedName("Menu")
#Expose
private Menu menu;
#SerializedName("status")
#Expose
private String status;
public Menu getMenu() {
return menu;
}
public void setMenu(Menu menu) {
this.menu = menu;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}
public class Dish {
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("code")
#Expose
private String code;
#SerializedName("name")
#Expose
private String name;
#SerializedName("price")
#Expose
private String price;
#SerializedName("veg")
#Expose
private String veg;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public String getVeg() {
return veg;
}
public void setVeg(String veg) {
this.veg = veg;
}
}
public class Item {
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("code")
#Expose
private String code;
#SerializedName("name")
#Expose
private String name;
#SerializedName("status")
#Expose
private String status;
#SerializedName("dishes")
#Expose
private List<Dish> dishes = null;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public List<Dish> getDishes() {
return dishes;
}
public void setDishes(List<Dish> dishes) {
this.dishes = dishes;
}
}
public class Menu {
#SerializedName("Items")
#Expose
private List<Item> items = null;
public List<Item> getItems() {
return items;
}
public void setItems(List<Item> items) {
this.items = items;
}
}
You may change the name of the classes if you want.
Now just change your onSuccess() method as follows:
Menuclass menuClassObject;
public void onSuccess(String response) {
menuClassObject = (new Gson()).fromJson(response,Menuclass.class);
}
Now the menuClassObject contains the response JSON converted to the class object.
MenuFragment's OnCreateView :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_tab1, container, false);
ListView listview = (ListView) view.findViewById(R.id.Listview1);
position = getArguments().getInt("position", 0);
MenuViewAdapter listViewAdapter = new MenuViewAdapter(getActivity(), menuClassObject,position);
listview.setAdapter(listViewAdapter);
return view;
}
}
Change your MenuViewAdapter :
public class MenuViewAdapter extends BaseAdapter {
private LayoutInflater layoutinflater;
private Menuclass menuClass;
private ArrayList<Dish> listStorage;
private Context context;
private int pagerPosition;
public MenuViewAdapter(Context context, Menuclass customMenuClass,int position) {
this.context = context;
layoutinflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
menuClass = customMenuClass;
pagerPosition = position;
listStorage = new ArrayList<>();
listStorage = menuClass.getMenu().getItems().get(position).getDishes();
}
#Override
public int getCount() {
return listStorage.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Dish dish = listStorage.get(position);
//Now Dish class has methods you need. Customize your view here based on the Dish.
}
