Android:Mapping json values to pojo

I am trying to map

JSON
values to POJO using
GSON
. When I try to get object back from
JSON
string all the variables are set to null.

here is my code

Pojo.java

public class PatientSymptoms {

private Integer AnalSymptomsMapId;
private Integer SymptomId;
private String Symptom;
private Boolean IsRemoved;
private Boolean IsSynced;
private Boolean IsSentToPatient;

//Getters and Setters
}


Mapping code

JSONObject jsonObject = (JSONObject) jsonArray.get(i);
PatientSymptoms symptoms = new PatientSymptoms();

Gson gson = new Gson();
String x = gson.toJson(jsonObject);
symptoms = gson.fromJson(x,PatientSymptoms.class);


but
PatientSymptoms
object values are always null. This is the screen shot of the debugger

debugger o/p

UPDATED JSON RESPONSE

{
"Success": true,
"StatusCode": 0,
"StatusMessage": "",
"Data": [
{
"AnalSymptomsMapId": 250,
"SymptomId": 95,
"Symptom": "asdf",
"IsRemoved": false,
"IsSynced": false,
"IsSentToPatient": true
}
]
}

Answer

Can you give us an example of the Json? (like an string)

(JSONObject) jsonArray.get(i).toString()

Anyway, I recomend you to use @SerializedName annotation from Gson to do the mapping:
