    @SerializedName("trainID")
 String trainID;
    @SerializedName("trainLastReportedAt")
 String trainLastReportedAt;
    @SerializedName("destinationStation")
 DestinationStation destinationStation;
    public deparaturedaseboarddto(String trainID,String toc,String trainLastReportedAt, String platformNo, String schDepart, String expDepart, int alertsId, String rid, String destSchArrival, String filteredStation, String destExpArrival, String toSchArrival, String toExpArrival,DestinationStation destinationStation){
        this.trainID=trainID;
        this.toc=toc;

how to get all objects of web service in holder object using gson

Answer 1

You can try to use fromJSON() from GSON

this is an example

@Override
public void getWebserviceResponse(String result) {
    Log.d("-----", "naveen"+ result);
    Holder data = new Gson().fromJson(result, Holder.class);
}
