I am reading a JSON like this:
{
"matches": [{
"id": 246119,
"utcDate": "2018-08-17T18:15:00Z",
"status": "FINISHED",
"homeTeam": {
"id": 298,
"name": "Girona FC"
},
"awayTeam": {
"id": 250,
"name": "Real Valladolid CF"
},
"score": {
"winner": "DRAW",
"duration": "REGULAR"
}
}]
}
I must say that the JSON is valid. I am consuming this JSON through an API. I can correctly read the properties "id", "utc" and "status", but I could not with "score", "awayTeam" and "homeTeam". I don't really know how to work those properties. I'd like to handle each propertie of score, awayTeam, and homeTeam individually, for example, I want to get just the name of awayTeam and homeTeam and the 2 properties of score.
This, is my code:
MainActivity
public class MainActivity extends AppCompatActivity {
private Retrofit retrofit;
private static final String TAG = "Football";
private RecyclerView recyclerView;
private ListaPartidosAdapter listaPartidosAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView)findViewById(R.id.recyclerView);
listaPartidosAdapter = new ListaPartidosAdapter(this);
recyclerView.setAdapter(listaPartidosAdapter);
recyclerView.setHasFixedSize(true);
final LinearLayoutManager layoutManager = new LinearLayoutManager(this, VERTICAL, true);
recyclerView.setLayoutManager(layoutManager);
retrofit = new Retrofit.Builder()
.baseUrl("http://api.football-data.org/v2/")
.addConverterFactory(GsonConverterFactory.create())
.build();
obtenerDatos();
}
private void obtenerDatos() {
footballdataService service = retrofit.create(footballdataService.class);
Call<PartidosRespuesta> partidosRespuestaCall = service.obtenerlistaPartidos();
partidosRespuestaCall.enqueue(new Callback<PartidosRespuesta>() {
#Override
public void onResponse(Call<PartidosRespuesta> call, Response<PartidosRespuesta> response) {
if(response.isSuccessful()) {
PartidosRespuesta partidosRespuesta = response.body();
ArrayList<Partido> listaPartidos = partidosRespuesta.getMatches();
listaPartidosAdapter.adicionarListaPartidos(listaPartidos);
}
else {
Log.e(TAG, "onResponse: " + response.errorBody());
}
}
#Override
public void onFailure(Call<PartidosRespuesta> call, Throwable t) {
Log.e(TAG, "onFailure: " + t.getMessage());
}
});
}
}
Now this is my interface. footballdataService
public interface footballdataService {
#GET("competitions/2014/matches")
Call<PartidosRespuesta> obtenerlistaPartidos();
}
This is PartidosRespuestas class
public class PartidosRespuesta {
private ArrayList<Partido> matches;
public ArrayList<Partido> getMatches() {
return matches;
}
public void setMatches(ArrayList<Partido> matches) {
this.matches = matches;
}
}
This, is the adapter.
public class ListaPartidosAdapter extends RecyclerView.Adapter<ListaPartidosAdapter.ViewHolder> {
private static final String TAG = "Football_Adapter";
private ArrayList<Partido> dataset;
private Context context;
public ListaPartidosAdapter(Context context) {
this.context = context;
dataset = new ArrayList<Partido>();
}
#Override
public ListaPartidosAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_partidos, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ListaPartidosAdapter.ViewHolder holder, int position) {
Partido p = dataset.get(position);
holder.status.setText(p.getId());
}
#Override
public int getItemCount() {
return dataset.size();
}
public void adicionarListaPartidos(ArrayList<Partido> listaPartidos){
dataset.addAll(listaPartidos);
notifyDataSetChanged();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView status;
public ViewHolder(View itemView) {
super(itemView);
status = (TextView) itemView.findViewById(R.id.status);
}
}
}
And this.., is Partido class
public class Partido {
private String id;
private String utcDate;
private String status;
private EquipoCasa homeTeam;
private EquipoVisita AwayTeam;
private Puntaje score;
public String getId() {
return id;
}
public String getUtcDate() {
return utcDate;
}
public String getStatus() {
return status;
}
public EquipoCasa getHomeTeam() {
return homeTeam;
}
public EquipoVisita getAwayTeam() {
return AwayTeam;
}
public Puntaje getScore() {
return score;
}
public void setId(String id) {
this.id = id;
}
public void setUtcDate(String utcDate) {
this.utcDate = utcDate;
}
public void setStatus(String status) {
this.status = status;
}
public void setHomeTeam(EquipoCasa homeTeam) {
this.homeTeam = homeTeam;
}
public void setAwayTeam(EquipoVisita awayTeam) {
AwayTeam = awayTeam;
}
public void setScore(Puntaje score) {
this.score = score;
}
public class EquipoCasa {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class EquipoVisita {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class Puntaje {
private String winner;
private String duration;
public String getWinner() {
return winner;
}
public void setWinner(String winner) {
this.winner = winner;
}
public String getDuration() {
return duration;
}
public void setDuration(String duration) {
this.duration = duration;
}
}
}
POJO classes of your code should this:
AwayTeam.java
//AwayTeam
public class AwayTeam {
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("name")
#Expose
private String name;
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;
}
}
PartidosRespuesta.java
//Object response
public class PartidosRespuesta {
#SerializedName("matches")
#Expose
private List<Match> matches = null;
public List<Match> getMatches() {
return matches;
}
public void setMatches(List<Match> matches) {
this.matches = matches;
}
}
HomeTeam.java
//HomeTeam
public class HomeTeam {
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("name")
#Expose
private String name;
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;
}
}
Score.java
//Score
public class Score {
#SerializedName("winner")
#Expose
private String winner;
#SerializedName("duration")
#Expose
private String duration;
public String getWinner() {
return winner;
}
public void setWinner(String winner) {
this.winner = winner;
}
public String getDuration() {
return duration;
}
public void setDuration(String duration) {
this.duration = duration;
}
}
Edit:
#Override
public void onBindViewHolder(ListaPartidosAdapter.ViewHolder holder, int position) {
Partido p = dataset.get(position);
HomeTeam homeTeam = p.getHomeTeam();
String nameHomeTeam = homeTeam.getName();
}
And tool convert json to java code: http://www.jsonschema2pojo.org/
try
public class Puntaje {
public String winner;
public String duration;
}
It's seems like you've problems with your models. Use this link to convert your json to java object.

I am trying to insert realm lists to my realmdb in my first insert there is no problem but when I insert another realmList with a different class, my old values are deleted. So how can I insert a realmlist to DB? inserts are done separately.
RealmList<Product> insertedProduct = new RealmList<Product>();
RealmList<ProductSubCategory> insertedSubCategory = new RealmList<ProductSubCategory>();
RealmList<ProductMainCategory> insertedMainCategory = new RealmList<ProductMainCategory>();
... inserting to realm list firt time ...
insertRealmList(insertedProduct); //inserting to realmDB first time
insertRealmList(insertedSubCategory); //inserting to realmDB first time
insertRealmList(insertedMainCategory); //inserting to realmDB first time
first insert to realmDB
RealmList insert function
private void insertRealmList(final RealmList realmObject) {
mRealm = Realm.getDefaultInstance();

I've been searching online and on here and I have been unable to find how exactly to use GSON with my code which is:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_weather_app, container, false);
mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
mRecyclerView.addItemDecoration(new DividerItemDecoration(mRecyclerView.getContext(), DividerItemDecoration.VERTICAL));
requestJsonObject();
return view;
}
private void requestJsonObject (){
}
How exactly do I add the GSON parsing to my code? I only need the temperature, max, min, weather and humidity?
EDIT:
Here is some more info. I plan on using a normal http connection with an apikey to get my information. I am also planning on using RecyclerView and here is that code:
public class RecyclerViewAdapter extends
RecyclerView.Adapter<RecyclerViewAdapter.CurrentRecycler> {
List<Weather> mCurrentWeatherDataList;
public static class CurrentRecycler extends RecyclerView.ViewHolder{
public TextView location;
public TextView currentTemp;
public TextView currentHumidity;
public TextView currentDescription;
public ImageView currentIcon;
public CurrentRecycler (View view) {
super (view);
location = (TextView) view.findViewById(R.id.current_city_location);
currentTemp = (TextView) view.findViewById(R.id.current_temperature);
currentHumidity = (TextView) view.findViewById(R.id.current_humidity);
currentDescription = (TextView) view.findViewById(R.id.current_weather_description);
currentIcon = (ImageView) view.findViewById(R.id.current_weather_icon);
}
}
public RecyclerViewAdapter (List<Weather> mCurrentWeatherDataList) {
this.mCurrentWeatherDataList = mCurrentWeatherDataList;
}
#Override
public CurrentRecycler onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_item, parent, false);
final CurrentRecycler currentRecycler = new CurrentRecycler(view);
return currentRecycler;
}
#Override
public void onBindViewHolder( CurrentRecycler holder, int position) {
final Weather currentRecycler = mCurrentWeatherDataList.get(position);
holder.location.setText(currentRecycler.getDefaultLocation());
holder.currentTemp.setText((currentRecycler.getDefaultCurrentTemp()));
holder.currentHumidity.setText(currentRecycler.getDefaultHumidity());
holder.currentDescription.setText(currentRecycler.getDefaultDescription());
}
#Override
public int getItemCount() {
return mCurrentWeatherDataList.size();
}
}
In your requestJsonObject method, use volley or okhttp to fetch the weather data from API.
Once you get the data as a String, you can use the following code:
List list = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create().fromJson(str, List.class);
Main main = list.getDt();
main.getTemp();
main.getTempMin();
main.getTempMax();
str means your api response data. List means your first entity class.
Moreover, I strongly recommend you to rename your class name, never try to use the reserved name of Java, make them meaningful.
This is my JSON:
I need to access to extra_services and get the service_name.
I know I can do it directly using Gson but the problem is that I need to use getters and setters because I'm using an adapter inside of a recycler, how can I do that?
here is my adapter class where I need to get the service name
public class ExtraServicesAdapter extends RecyclerView.Adapter<ExtraServicesAdapter.ViewHolder> implements View.OnClickListener
{
private ArrayList<Business> businessList;
private Activity activity;
private int layoutMolde,idb;
public ExtraServicesAdapter(Activity activity, ArrayList<Business> list, int layout)
{
this.activity = activity;
this.businessList = list;
layoutMolde = layout;
}
#Override
public ExtraServicesAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
{
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_services_basic, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position)
{
if(businessList.get(position).getExtra_services()==null)
{
holder.txtNameServiceBasic.setText("There's nothing to show");
}
holder.txtNameServiceBasic.setText(businessList.get(position).getExtra_services());
}
#Override
public int getItemCount()
{
return businessList.size();
}
#Override
public void onClick(View v)
{
}
public class ViewHolder extends RecyclerView.ViewHolder
{
public TextView txtNameServiceBasic;
public ViewHolder( View itemView)
{
super(itemView);
txtNameServiceBasic = (TextView) itemView.findViewById(R.id.txtNameServiceBasic);
}
}
}
and this is my class where are the getters and setters that I'm using
public class Business {
private Integer id,rating;
private String name, description, cover_url_string, logo_url_string, icon_default,business_name,cover_default,extra_services;
private Boolean status;
public Business(){}
public Business(Integer id,Integer rating,String business_name, String name, String description, String logo_url_string, String cover_default, String icon_default,String cover_url_string,String extra_services) {
this.id = id;
this.name = name;
this.business_name=business_name;
this.description = description;
this.logo_url_string = logo_url_string;
this.cover_url_string = cover_url_string;
this.rating=rating;
this.icon_default=icon_default;
this.cover_default=cover_default;
this.extra_services=extra_services;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getRating() {
return rating;
}
public String getBusiness_name() {
return business_name;
}
public void setBusiness_name(String business_name) {
this.business_name = business_name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getLogo_url_string() {
return logo_url_string;
}
public void setLogo_url_string(String logo_url_string) {
this.logo_url_string = logo_url_string;
}
public String getIcon_default() {
return icon_default;
}
public String getCover_default() {
return cover_default;
}
public String getCover_url_string() {
return cover_url_string;
}
public String getExtra_services() {
return extra_services;
}
public void setExtra_services() {
this.extra_services=extra_services;
}
}
You can add an ExtraServices class that contains a list of ExtraService
ExtraService
public class ExtraService {
private String Id;
private String ServiceName;
public String getId() {
return Id;
}
public void setId(String Id) {
this.Id = Id;
}
public String getServiceName() {
return ServiceName;
}
public void setServiceName(String ServiceName) {
this.ServiceName = ServiceName;
}
ExtraServices
public class ExtraServices {
private List<ExtraService> extraServicesList;
public List<ExtraService> getExtraServicesList() {
return extraServicesList;
}
public void setExtraServicesList(List<ExtraService> extraServicesList) {
this.extraServicesList = extraServicesList;
}
public void add(ExtraService extraService){
if(extraServicesList == null){
extraServicesList = new ArrayList<>();
}
extraServicesList.add(extraService);
}
And in your Business class add getters and setters of ExtraServices
private ExtraServices extraServices;
public ExtraServices getExtraServices () {
return extraServices;
}
public void setExtraServices (ExtraServices extraServices) {
this.extraServices = extraServices;
}
After you have to do the setter process and in your Adapter you should do something like this:
holder.txtNameServiceBasic.setText(businessList.get(position).getExtraServices().getExtraServicesList().get(posistion).getServiceName());
I want to get data from my localhost with retrofit library. I want to make it so that when I click the button, all TextView will set new value. For example, TextView username will change "developer" in my json file. However, when I clicked the button I guess json returned null because I can not see anything. Can you help me solve this problem?

This is retrofir request.
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constants.BASERESTURL)
.addConverterFactory(GsonConverterFactory.create())
.build();
I am Parsing the data with gson library in retrofit response
public void onResponse(retrofit.Response<List<Category>> response, Retrofit retrofit) {
loading.dismiss();
List<Category> categories = response.body();
Collections.sort(categories);
Utility.setCategories(categories);
}
i can sort the categories with Collections.sort(categories);
But how to sort subcategories with category??
You can do this right in setSubcategories, so everytime you set new subcategories they will get sorted:
public void setSubcategories(List<SubCategory> subcategories) {
Collections.sort(subcategories)
this.subcategories = subcategories;
}
Also you should replace this.subcategories = subcategories; with this.setSubcategories(subcategories) in your Constructor.
