get map inside map java android

I have this JSON response.
I want to fetch the times data that is inside datetime.
{
"code":200,
"status":"OK",
"results":{
"datetime":[
{
"times":{
"Imsak":"04:21",
"Sunrise":"-",

How to get object "times" and take it into the map.
How to take the individual values as well as an array.

Below code will make "times" object. Like:
String json = "{\"code\":200,\"status\":\"OK\",\"results\":{\"datetime\":[{\"times\":{\"Imsak\":\"04:21\",\"Sunrise\":\"-\",\"Fajr\":\"04:31\",\"Dhuhr\":\"11:41\",\"Asr\":\"14:58\",\"Sunset\":\"-\",\"Maghrib\":\"17:54\",\"Isha\":\"18:46\",\"Midnight\":\"-\"},\"date\":{\"timestamp\":1617667200,\"gregorian\":\"2021-04-06\",\"hijri\":\"1442-08-24\"}}],\"location\":{\"latitude\":-6.966667,\"longitude\":110.416664,\"elevation\":-9999.0,\"country\":\"\",\"country_code\":\"ID\",\"timezone\":\"Asia/Jakarta\",\"local_offset\":7.0},\"settings\":{\"timeformat\":\"HH:mm\",\"school\":\"Ithna Ashari\",\"juristic\":\"Shafii\",\"highlat\":\"None\",\"fajr_angle\":18.0,\"isha_angle\":17.0}}}";
try {
JSONObject rootJsonObject = new JSONObject(json);
JSONObject resultJsonObject = rootJsonObject.getJSONObject("results");
JSONArray dateTimeJsonArray = resultJsonObject.getJSONArray("datetime");
JSONObject timeJsonObject = new JSONObject(dateTimeJsonArray.get(0).toString());
JSONObject timeJson = new JSONObject(timeJsonObject.getString("times"));
Log.d("TAG","Time json = "+timeJson);
}catch (JSONException jsonException){
Log.d("TAG","JSON Exception: "+jsonException.getLocalizedMessage());

from the response, identity type is actually a string, I really don't know where I am getting it wrong
"identity_type": "driver's license",

You have mentioned identity_type is an object but you are receiving a string
#SerializedName("identity_type")
#Expose
private Terminal identityType;
Change Terminal to String it would work.

Your identity_type is coming as String but you have declared as Terminal.
Change from
#SerializedName("identity_type")
#Expose
private Terminal identityType;
To
#SerializedName("identity_type")
#Expose
private String identityType;
Hope this will help you.

How to display JSON data from API server in TextView and EditText in Android?

I am trying to get the value of a JSON response and display it in my textView and editText. But I get a null object reference as an error.
JSON Response:
{
"srNo": 1,
"date": "11/14/2019 12:00:00 AM",
"fieldEngineer": "Angel",
"accountName": "Forever 21 Megamall",
"irNo": 1,
"joNo": 1,
"address": "Mandaluyong City",
"contactPerson": "Jansen Babon",
"designation": "",
"contactNo": "",
"email": "",
"timeIn": "00:00:00",
"timeOut": "00:00:00",
"productType": "Security",
"problem": ""
}
Java class:
private void fetchData() {
JsonObject paramObject = new JsonObject();
Call<ResObj> call = userService.userLogin(paramObject);
call.enqueue(new Callback<ResObj>() {
#Override
public void onResponse(Call<ResObj> call, retrofit2.Response<ResObj> response) {
ResObj resObj = response.body();
String srNo = resObj.getSrNo();
String date = resObj.getDate();
String fieldEngineer = resObj.getFieldEngineer();
String accountName = resObj.getAccountName();
String irNo = resObj.getIrNo();
String joNo = resObj.getJoNo();
String address = resObj.getAddress();
String contactPerson = resObj.getContactPerson();
String designation = resObj.getDesignation();
String contactNo = resObj.getContactNo();
String email = resObj.getEmail();
String timeIn = resObj.getTimeIn();
String timeOut = resObj.getTimeOut();
String productType = resObj.getProductType();
String problem = resObj.getProblem();
//the response I am getting here is null
tvSrNo.setText(srNo);
etdate.setText(date);
etfieldengineer.setText(fieldEngineer);
etaccname.setText(accountName);
etirno.setText(irNo);
etjono.setText(joNo);
JsonObject workObj = new JsonObject();
try {
workObj.addProperty("srNo", resObj.getSrNo());
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void onFailure(Call<ResObj> call, Throwable t) {
}
});
}
I tried using this tvSrNo.setText(resObj.getSrNo()) instead of tvSrNo.setText(srNo) but it still gets the same problem.
I am also using Retrofit.
I expect the result that JSON data will be placed in an editText or textView. But apparently, the response is getting null.

make sure to have Gson Converter in your retrofit instance
private static Retrofit getRetrofitInstance() {

}
then make call and put the data in ArrayList

first : Check response output,
you can Log.i or Toast it,,,
If your response not load or null ... - (the Problem in here)
Second : if respon Ok, Check your ResObj.getSrNo().
Print again... check
String srNo = resObj.getSrNo();
Log.i srNo... (problem or not)
Or checkyour Class Codebeautify

JsonObject paramObject = new JsonObject();
Call<ResObj> call = userService.userLogin(paramObject); // paramObject is empty object
You are passing empty JsonObject to your API parameter.
So you have to add parameter value to your paramObject. like this
try {
JsonObject paramObject = new JsonObject();
paramObject.addProperty("mobile", mobile);
// add other properties if you have
} catch (JSONException e) {
e.printStackTrace();
}
after that you should call your api like
Call<ResObj> call = userService.userLogin(paramObject);

As i am seeing the problem is in parsing, The retrofit can not mapping as your response is n't having ResObj as root.
{ "ResObj": { "srNo": 1, "date": "11/14/201912: 00: 00AM", "fieldEngineer": "Angel", "accountName": "Forever21Megamall", "irNo": 1, "joNo": 1, "address": "MandaluyongCity", "contactPerson": "JansenBabon", "designation": "", "contactNo": "", "email": "", "timeIn": "00: 00: 00", "timeOut": "00: 00: 00", "productType": "Security", "problem": "" } }
Modify your response or change your request
Call<JSONObject> call = userService.userLogin(paramObject);
Later in extract the values manually.

JsonIllegalstateexception:- Expected BEGIN_ARRAY but was String at line 1 column 61 . $ customer.Data

Expected BEGIN_ARRAY but was String at line 1 column 61 . $ customer.Data

Customer_Event is Arraylist
#SerializedName("Customer_Event")
#Expose
private List<CustomerEvent> customerEvent = null;

Gson Library expecting the Array first not the Object. there is nothing wrong in your code. but need to modify the JSON Structure here.
Try using this structure :
Note rootArray is starting point/ is used for your reference
rootArray[
// object
{
"Key": value,
"Key": value,
"Key": value
}
// array1
"Customer_Data":[
{
"Key": value,
"Key": value,
"Key": value
}
],
// array 2
"All_Event": [
{
"Key": value,
"Key": value,
"Key": value
}
]
]

You should choose to annotate object properties or getters. Don't use it simultaneously.

Apart, #xl0e answer
You need to correct mapping
#OneToMany(mappedBy = "testCaseForm", cascade = CascadeType.ALL)
public ArrayList<TestCaseStepsForm> getTestCaseStepsform() {
return testCaseStepsform;
}
