}
} catch (Exception e) {

}
This should do it
JSONObject custom_fields = post.getJSONObject("custom_fields");
JSONArray event_start_date_array = custom_fields.getJSONArray("event_start_date");
JSONArray event_location_array = custom_fields.getJSONArray("event_location");
String event_start_date = event_start_date_array.getString(0);
String event_location = event_location_array.getString(0);

I have a response which contains values which I need.
private void getDataFromDistanceMatrixToSaveAndAddToList(
GRATestDataImport place, String response) {
JSONObject responseAsJson = new JSONObject(response).getJSONArray("rows")
.getJSONObject(0)
.getJSONArray("elements")
.getJSONObject(0);
}
'response' in params includes:
{
"destination": [
"54.375,18.59"
],
"origin": [
"54.001,21.721"
],
"rows": [
{
"elements": [
{
"distance": {
"text": "304.4 km",
"value": 304403
},
"duration": {
"text": "3 h 53 min",
"value": 14003
},
"status": "OK"
}
]
}
],
"status": "OK"
}
value: 'responseAsJson' in my method is:
{
"duration": {
"text": "3 h 53 min",
"value": 14003
},
"distance": {
"text": "304.4 km",
"value": 304403
},
"status": "OK"
}
How can I get value from the duration and the distance ?
you'll just have to navigate along
int duration = responseAsJson.getJSONObject("duration").getInt("value");
int distance = responseAsJson.getJSONObject("distance").getInt("value");
public class YourResponse
{
public string duration { get; set; }
public string distance { get; set; }
}
YourResponse response = JsonSerializer.Deserialize<YourResponse>(result);
This is my JSON data i want to parse but am still new in deserialization, i want to get the following Attributes from this JSON data :
1.AirportCode.
2.Latutude.
3.Longitude.
This is the JSON containing two lists of the Airports.
{
"AirportResource": {
"Airports": {
"Airport": [{
"AirportCode": "AAL",
"Position": {
"Coordinate": {
"Latitude": 57.09305556,

},

}],
"TotalCount": 1261
}
}
}
Then my Java code:
EDITTED:
private void parseJson(String result)
{
try {
if (result!=null) {
JSONObject obj = new JSONObject(result).getJSONObject("AirportResource").getJSONObject("Airports");
JSONArray arr = obj.getJSONArray("Airport");
for (int i = 0; i < arr.length(); i++)
{
String AirportCode = arr.getJSONObject(i).getString("AAL");
String Latitude = arr.getJSONObject(i).getJSONObject("Position").getJSONObject("Coordinate").getString("Latitude");
String Longitude = arr.getJSONObject(i).getJSONObject("Position").getJSONObject("Coordinate").getString("Longitude");
System.out.println("Airport : " + AirportCode + " Latitude: " + Latitude+
" Longitude : " + Longitude );
}
}
else{
Toast.makeText(MainActivity.this,Config.POOR_NETWORK_CONNECTION, Toast.LENGTH_LONG).show();
}
}
catch (JSONException r){
System.out.println("ERROR PROB : "+ r);
}
}
The exception am getting is :
org.json.JSONException: No value for AirportResource
How can i parse this JSON kind of Data?
This will HOPEFULLY get you started.
private static void parseJson(JSONObject object) throws JSONException {
if (object!=null) {
JSONObject airportResource = object.getJSONObject("AirportResource");
JSONObject airports = airportResource.getJSONObject("Airports");
JSONArray airportArray = airports.getJSONArray("Airport");
for (int i = 0 ; i < airportArray.length(); i++) {
JSONObject airport = (JSONObject) airportArray.get(i);
//System.out.println(airport);
System.out.println("CityCode: " + airport.getString("CityCode"));
}
}
else{
//null
}
}
The output will be:
CityCode: AAL
CityCode: AAR
You didnt take the object of Airports. Inside Airports object is the Airport array and you are directly accessing it. Hence throwing error.
JSONObject obj2 = obj.getJSONObject("Airports");
Now get Json Array from obj
JsonArray jsonarray= obj2.getJsonArray("Airport");
Use the for loop on jsonarray's length now.
I recommend using this tool to view and formate your JSON properly.
this is the result
from here you could easily resolve your problem
JSONObject AirportResource= obj.getJSONObject("AirportResource");
JsonArray AirPorts= AirportResource.getJSONObject("Airports");
JsonArray jsonarray= AirPorts.getJsonArray("Airport");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject obj= AirportResource.get(i); do sth with it
obj.getString("key"); //do sth with it
}

need to parse this reponse in json. Please help me out.
You can try something like this..
try{
JSONArray array= new JSONArray(Yourresponse);
for(int i=0; i<=array.length();i++){
JSONObject jsonObject=array.getJSONObject(i);
String id= jsonObject.getString("id");
String created_at= jsonObject.getString("createdAt");
String model_id = jsonObject.getJSONObject("model").getString("id");
String app_id=jsonObject.getJSONObject("model").getString("app_id");
//So On... Depends on your requirements. It's just an idea!
}
}
catch (Exception e){
e.printStackTrace();

I am trying to create android app that shows details about the restaurants. I have parseJSON function which takes string json as an argument. What I am trying to do for now is to show name of individual restaurants in the json below. I am able to extract individual restaurant(3 levels deep) and print them out through log.d console but I am not able to extract out the individual restaurant's name. Here is the code
public void parseJSON(String jsonQuery){
//Parsing JSON
try {
JSONObject jsonObject = new JSONObject(jsonQuery);
if (jsonObject != null){
JSONArray restaurants = jsonObject.getJSONArray("restaurants");
for (int i = 0; i < restaurants.length(); i++){
JSONObject restaurant = restaurants.getJSONObject(i);
if (restaurant != null){
String tempName = restaurant.getString("name");
Log.d(TAG, "Restaurant name: " + tempName);
}
}
}
} catch (JSONException e) {
Log.d(TAG, "Exception catched: " + e);

Error which I am getting:
org.json.JSONException: No value for name
Your jsonQuery contain JsonObject inside JsonObject named restaurant so you need to get JsonObject from JSONObject restaurant = restaurants.getJSONObject(i);
Like JSONObject restaurantsJSONObject =restaurant.getJSONObject("restaurant");
Try below example to get name from object
try {
JSONObject jsonObject = new JSONObject(jsonQuery);
if (jsonObject != null){
JSONArray restaurants = jsonObject.getJSONArray("restaurants");
for (int i = 0; i < restaurants.length(); i++){
JSONObject restaurant = restaurants.getJSONObject(i);
JSONObject restaurantsJSONObject =restaurant.getJSONObject("restaurant");
if(restaurantsJSONObject.has("name")) {
String tempName = restaurantsJSONObject.getString("name");
Log.d(TAG, "Restaurant name: " + tempName);

I need books titles and their URL. I run the below code but I get Exception in thread "main" java.lang.ClassCastException: org.json.simple.JSONObject cannot be cast to java.lang.String
while ((inputLine = in.readLine()) != null)
{
s = s + inputLine + "\r\n";
if (s == null) {
break;
}
t = t + inputLine + "\r\n";
}
in.close();
t = t.substring(0, t.length() - 2);
System.out.println(t);
Object dataObj =JSONValue.parse(t);
System.out.println(dataObj);
JSONObject dataJson = (JSONObject) dataObj;
JSONArray data = (JSONArray) dataJson.get("data");
for (Object o: data)
{
JSONObject indata= (JSONObject) o;
Object indatafirst=(JSONObjec`enter code here`t).get("0");
String inndata=(String) indatafirst.get("data");
System.out.println("inndata"+inndata);
}}
but it is not true
The problem is with the following line:
String inndata=(String) indatafirst.get("data");
The data field in the JSON is not a String, it's a nested JSON object.
"data": {
"book": {
"id": "104081659627680",
"url": "https://www.facebook.com/pages/Gulistan-of-Sadi/104081659627680",
"type": "books.book",
"title": "Gulistan of Sa'di"
}
}
This explains your ClassCastException.
Instead you should do something like:
JSONObject data = (JSONObject) indatafirst.get("data");
JSONObject book = (JSONObject) data.get("book");
String bookTitle = book.get("title");
