I am using retrofit to make a request using the RxJava method. However, Gson doesn't seem to recognize the nested parts of my data and put it in the appropriate Model.
Retrofit retrofit= new Retrofit.Builder()
.baseUrl(API_URL)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
My Models look like this
public class StopSchedule implements Serializable {
@SerializedName("query-time")
private String mQueryTime;
@SerializedName("route-schedules")
@Expose
private List<RouteSchedule> mRouteSchedules;
@SerializedName("stop")
private Stop mStop;
@SerializedName("stop-schedule")
private StopSchedule mStopSchedule;
public String getQueryTime() {
return mQueryTime;
}
public List<RouteSchedule> getRouteSchedules() {
return mRouteSchedules;
}
public Stop getStop() {
return mStop;
}
public StopSchedule getStopSchedule() {
return mStopSchedule;
}
public static class Builder {
private String mQueryTime;
private List<RouteSchedule> mRouteSchedules;
private Stop mStop;
private StopSchedule mStopSchedule;
public StopSchedule.Builder withQueryTime(String queryTime) {
mQueryTime = queryTime;
return this;
}
public StopSchedule.Builder withRouteSchedules(List<RouteSchedule> routeSchedules) {
mRouteSchedules = routeSchedules;
return this;
}
public StopSchedule.Builder withStop(Stop stop) {
mStop = stop;
return this;
}
public StopSchedule.Builder withStopSchedule(StopSchedule stopSchedule) {
mStopSchedule = stopSchedule;
return this;
}
public StopSchedule build() {
StopSchedule StopSchedule = new StopSchedule();
StopSchedule.mQueryTime = mQueryTime;
StopSchedule.mRouteSchedules = mRouteSchedules;
StopSchedule.mStop = mStop;
StopSchedule.mStopSchedule = mStopSchedule;
return StopSchedule;
}
}
}
I also have RouteSchedule class model and other class models. However, after the normal response from retrofit using a single, my RouteSchedule model is empty.
Is there a way I can get route-schedule array alone or make sure it doesn't return an empty model.
Gson.fromJson(yourResponseString, StopSchedule.class)(syntax might be off slightly - from memory)? Same can be done for the nested object, just parse the relevant section of the Json string.
