Here is ApiInterface.java
public interface ApiInterface {
@GET(\"bills/\")
Call<SponsorsResult> getListOfSponsors(@Query(\"bill_id\") String billId , @Query(\"session\") String session, @Query(\"fields\") String field);
}
And here is call of method & response :
ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
Call<SponsorsResult> call = apiService.getListOfSponsors(AppConstants.ASSEMBLY_BILL_ID,AppConstants.SESSION,AppConstants.FIELD);
call.enqueue(new Callback<SponsorsResult>() {
@Override
public void onResponse(Call<SponsorsResult> call, Response<SponsorsResult> response) {
Log.d(TAG,\"Number :\"+response.raw());
List<Sponsor> sponsors = response.body().getSponsors();
Log.d(TAG,\"Number of sponsors :\"+ sponsors.size());
}
@Override
public void onFailure(Call<SponsorsResult> call, Throwable t) {
t.printStackTrace();
}
});
As of now it fails & here is logcat output :
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $
It fails to execute response . Guide me to parse this response.
回答1:
Please try to use this one
@FormUrlEncoded
@POST("api/sponsors")
Call<List<SponsorsResult>> getStatesAndDistrict(
@Field("xyz") String field1
);
Call <List<SponsorsResult>> call = service.getSponsorsValue();
call.enqueue(new Callback<List<SponsorsResult>>() {
@Override
public void onResponse(Call<List<SponsorsResult>> call, Response<List<SponsorsResult>> response) {
List<SponsorsResult> rs = response.body();
}
@Override
public void onFailure(Call<List<SponsorsResult>> call, Throwable t) {
}
});
class SponsorsResult {
@SerializedName("sponsors")
private List<SponsorsValue> sponsors;
public List<SponsorsValue> getSponsors() {
return sponsors;
}
}
class SponsorsValue{
@SerializedName("leg_id")
@Expose
private String legId;
@SerializedName("type")
@Expose
private String type;
@SerializedName("name")
@Expose
private String name;
public String getLegId() {
return legId;
}
public void setLegId(String legId) {
this.legId = legId;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Please let me know if you are facing any issue.
回答2:
You can create POJO classes from json response automatically using this link -> jsonschema2pojo
All you need to do is paste the JSON response in the edit box given.
- Select Target language as JAVA,
- Source type as JSON
- Annotation style as Gson
- and check Use primitive types , include getters and setters, allow additional properties
回答3:
Create below class in your model package:
import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class SponsorModel {
@SerializedName("sponsors")
@Expose
private List<Sponsor> sponsors = null;
@SerializedName("id")
@Expose
private String id;
public List<Sponsor> getSponsors() {
return sponsors;
}
public void setSponsors(List<Sponsor> sponsors) {
this.sponsors = sponsors;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
-----------------------------------Sponsor.java-----------------------------------
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class Sponsor {
@SerializedName("leg_id")
@Expose
private String legId;
@SerializedName("type")
@Expose
private String type;
@SerializedName("name")
@Expose
private String name;
@SerializedName("committee_id")
@Expose
private Object committeeId;
@SerializedName("official_type")
@Expose
private String officialType;
public String getLegId() {
return legId;
}
public void setLegId(String legId) {
this.legId = legId;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Object getCommitteeId() {
return committeeId;
}
public void setCommitteeId(Object committeeId) {
this.committeeId = committeeId;
}
public String getOfficialType() {
return officialType;
}
public void setOfficialType(String officialType) {
this.officialType = officialType;
}
}
Set above SponsorsModel in your result.
Thanks
