I have string json like this :
{
"listResult": {
"items": [
{
"id": "629047db-66d9-4986-ba3f-c75554198138",
"thumbnail": "http://maya-wdv-01.r.worldssl.net/39aa32db-6f50-4da1-8fd5-a5b001135b98/629047db-66d9-4986-ba3f-c75554198138/8cb69c17-0fdb-454c-bfb5-a5b9001a9d59.jpg"
},
{
"id": "fa872dc8-d2b3-4815-92ef-d90e903bc3d8",

}
],
"totalItems": 34,
"pageSize": 5,
"pageNumber": 1,
"totalPages": 7,
"searchTerm": null
}
}
I Try Parsing with code :
try {
JSONObject json = new JSONObject(response);
String listResult = json.getString(Variabel.listResult);
JSONArray items_obj = json.getJSONArray(Variabel.items);
int jumlah_list_data = items_obj.length();
if (jumlah_list_data > 0) {
for (int i = 0; i < jumlah_list_data; i++) {
JSONObject obj = items_obj.getJSONObject(i);
String id = obj.getString(Variabel.id);
String thumbnail = obj.getString(Variabel.thumbnail);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
But I getting Error :
org.json.JSONException: No value for items
So how to solve it ? sorry for my English
Instead of:
JSONObject json = new JSONObject(response);
String listResult = json.getString(Variabel.listResult);
JSONArray items_obj = json.getJSONArray(Variabel.items);
you should have:
JSONObject json = new JSONObject(response);
JSONObject listResult = json.getJSONObject(Variabel.listResult);
JSONArray items_obj = listResult.getJSONArray(Variabel.items);
Accordingly to the json you posted, items is direct child of listResult, so you have to use the JSONObject with key listResult to retrieve it. Change
JSONArray items_obj = json.getJSONArray(Variabel.items);
with
JSONArray items_obj = listResult.getJSONArray(Variabel.items);

How to parse JSON values in this format? I want to get the details of the data element but inside data there are 'dates' and inside dates there is array containing two more elements. I want to get all the dates first inside data and then within these dates I want all the information within these dates. How can I achieve this? Please Help. I tried with below code but it hasn't worked
try {
JSONObject jsonObject = new JSONObject("data");
JSONArray jsonArray =jsonObject.getJSONArray(String.valueof(cuurentdate));
JSONArray session;
for (int i = 0; i < jsonArray.length() - 1; i++) {
jsonObject = jsonArray.getJSONObject(i);
session= jsonObject.getJSONArray("session");
Log.d("MyLog", session + "");
}
} catch (JSONException e) {
e.printStackTrace();
}
Following is the format
{
"status": 1,
"status_code": 200,
"data": {
"2018-02-11": [
{
"session": "01:00 AM",
"place": true
},
{
"session": "02:00 AM",
"place": true
}
],
"2018-02-12": [
{
"session": "01:00 AM",
"place": true
},
{
"session": "02:00 AM",
"place": true
}
]
}
}
You just need to pass the response string to the method. You can try this:
private void jsonParsing(String jsonString) {
// String jsonString = "{ \"status\": 1, \"status_code\": 200, \"data\": { \"2018-02-11\": [ { \"session\": \"01:00 AM\", \"place\": true }, { \"session\": \"02:00 AM\", \"place\": true } ], \"2018-02-12\": [ { \"session\": \"01:00 AM\", \"place\": true }, { \"session\": \"02:00 AM\", \"place\": true } ] } }";
try {
JSONObject jsonObject = new JSONObject(jsonString);
JSONObject dataObj = jsonObject.getJSONObject("data");
Iterator<String> iter = dataObj.keys();
Log.e(TAG, "jsonParsing: "+iter );
while (iter.hasNext()) {
String key = iter.next();
JSONArray datesArray = dataObj.getJSONArray(key);
ArrayList<String> sessions = new ArrayList<String>();
for (int i = 0; i < datesArray.length(); i++) {
JSONObject datesObject = datesArray.getJSONObject(i);
sessions.add(datesObject.getString("session"));
}
Log.d("MyLog", sessions + "");
}
} catch (JSONException e) {
e.printStackTrace();
}
}
(1) get JSONObject of Main json
JSONObject objMain = new JSONObject("your json string");
(2)get JSONObject of "data" from main json
JSONObject jsonData = objMain.getJSONObject("data")
(3) get all keys (dates) from object "data"
Iterator<String> iter = jsonData.keys();
while (iter.hasNext()) {
String key = iter.next();
try {
JSONArray arrayDate = objData.getJSONArray(key)
for (i = 0; i < arrayDate.length(); i++) {
JSONObject objDate = arrayDate.getJSONObject(i)
Log.d("#session :", "" + objDate.getString("session"))
Log.d("#place :", "" + objDate.getBoolean("place"))
}
} catch (JSONException e) {
// Something went wrong!
}
}
try this one code
IN THIS CODE jsonMstObject IS TEMP OBJECT YOU HAVE TO USE YOUR API RESPONSE JSONobject INSTEAD OF jsonMstObject
try {
JSONObject jsonMstObject = new JSONObject("{"status":1,"status_code":200,"data":{"2018-02-11":[{"session":"01:00 AM","place":true},{"session":"02:00 AM","place":true}],"2018-02-12":[{"session":"01:00 AM","place":true},{"session":"02:00 AM","place":true}]}}");
JSONObject jsonObject = jsonMstObject.getJSONObject("data");
JSONArray jsonArray =jsonObject.getJSONArray(String.valueof(cuurentdate));
ArrayList<String> arrSession = new ArrayList<String>();
for (int i = 0; i < jsonArray.length(); i++) {
jsonObject = jsonArray.getJSONObject(i);
arrSession.add(jsonObject.getString("session"));
}
Log.d("MyLog", arrSession + "");
} catch (JSONException e) {
e.printStackTrace();
}
in this code arrSession is your session string array
Ex. you passed cuurentdate = "2018-02-11" then you recived result like
[01:00 AM, 02:00 AM]
Note: this code is worked based on your cuurentdate param. This is code for get static date array from data and create String Array.
I'm trying to parse a JSON object. The JSON response is as follows.
{
"message": "Success",
"list": [
{
"orderId": 24,
"phoneNumber": "1234567893",
"totalAmount": 100,
"addressBean": {
"cadId": 1,
"phone2": "1234567899",
"address1": "34, gandhi nagar",
}
},
Android code which i have tried for getting "orderId", "phoneNumber" and "totalAmount" is below.
final List<OrderModel> orderList = new ArrayList<>();
public void onResponse(JSONObject response) {
try {
if (response.getString("message").equalsIgnoreCase("Success")) {
JSONArray jArray = response.getJSONArray("list");
for (int i = 0; i < jArray.length(); i++) {
OrderModel model = new OrderModel();
orderModel.setOrderId(jArray.getJSONObject(i).getString("orderId"));
orderModel.setphoneNumber(jArray.getJSONObject(i).getString("phoneNumber"));
orderModel.setTotalAmount(new BigDecimal(jArray.getJSONObject(i).getString("totalAmount")));
orderList.add(orderModel);
}
setOrderList(orderList);
I want to show the "cadId", "phone2" and "address1" in a Textview. How can i do that?
Try to use this Code
try {
JSONArray jArray = response.getJSONArray("list");
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsonObject = jArray.getJSONObject(i);
if (jsonObject.has("addressBean")){
JSONObject addressObject = jsonObject.getJSONObject("addressBean");
int cadId = addressObject.getInt("cadId");
String phone = addressObject.getString("phone2");
String address = addressObject.getString("address1");
}
}
} catch (JSONException e) {
e.printStackTrace();
}
Code for phone2
String phone2 = jArray.getJSONObject(i).getJSONObject("addressBean").getString("phone2");
Use getInt() for cadId

JSON array parsing in android

Closed 7 years ago.
I have a JSON response in this format:
{
"success": true,
"categories": [{
"id": "774",
"name": "1"
}, {
"id": "774",
"name": "1"
}]
}
And I am parsing it like this:
try {
JSONObject obj = new JSONObject(response);
String success = String.valueOf(obj.getBoolean("success"));
JSONArray arr = obj.getJSONArray("categories");
//loop through each object
for (int i=0; i<arr.length(); i++) {
JSONObject jsonProductObject = arr.getJSONObject(i);
String name = jsonProductObject.getString("name");
String url = jsonProductObject.getString("id");
Toast.makeText(getApplicationContext(),name, Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
But I only get the value of success. What I'm doing wrong here?
Parse as below -
JSONObject obj = new JSONObject(json);
String success = obj.getString("success");
JSONArray arr = obj.getJSONArray("categories");
//loop through each object
for (int i=0; i<arr.length(); i++) {
JSONObject jsonProductObject = arr.getJSONObject(i);
String name = jsonProductObject.getString("name");
String url = jsonProductObject.getString("id");
}
correct json key
JSONArray arr = obj.getJSONArray("checkouts");
replace by:
JSONArray arr = obj.getJSONArray("categories");
DO like this,
if (!result.equalsIgnoreCase("")) {
try {
JSONObject _jsonObject = new JSONObject(result);
boolean json = false;
json = _jsonObject.getBoolean("Status");
JSONArray jsonArray1 = _jsonObject.getJSONArray("categories");
for (int i=0; i<jsonArray1.length(); i++) {
JSONObject jsonObject = jsonArray1.getJSONObject(i);
String name = jsonObject.getString("name");
String id = jsonObject.getString("id");
}
} catch (Exception e) {
Utils.printLoge(5, "error parse json", "--->" + e.getMessage());
return "ERROR";
}
}
how to get json data with android
my json like this:
[

My code
JSONObject jsonobject = JSONfunctions.getJSONfromURL("URL");
JSONArray jsonarray = jsonobject.getJSONArray("data");
for (int i = 0; i < jsonarray.length(); i++) {
jsonobject = jsonarray.getJSONObject(i);
Log.i("ID", jsonobject.getString("category_id"));
Log.i("Name", jsonobject.getString("name"));
}
i want get "data" array.
please help if anybody know:
Thank You.
Try this.
JSONArray total_array = new JSONArray(string json);
JSONArray data_array = total_array.getJSONObject(1).getJSONArray("data");
for(int i = 0; i < data_array.length(); i++){
JSONObject json_data = data_array.getJSONObject(i);
String category_id = json_data.getString("category_id");
}
Probably this may help you :
JSONArray jsonArray;
try {
jsonArray = new JSONArray("YOUR JSON DATA");
Log.v("MAIN ACTIVITY", "JSON OBJECT :"+jsonArray.getJSONObject(0).getJSONObject("meta").getString("next_id"));
JSONArray dArray = jsonArray.getJSONObject(1).getJSONArray("data");
for(int i=0;i<dArray.length();i++)
{
JSONObject jsonObject = dArray.getJSONObject(i);
Log.v("MAIN ACTIVITY", "JSON DATA :"+jsonObject.getString("category_id"));
Log.v("MAIN ACTIVITY", "JSON DATA :"+jsonObject.getString("name"));
Log.v("MAIN ACTIVITY", "JSON DATA :"+jsonObject.getString("count"));
}
}
catch (JSONException e1) {
e1.printStackTrace();
}
to get json array
JSONArray jsonArray = new JSONArray(jsonStr);
JSONArray dataArray= jsonArray.getJSONObject(1).getJSONArray("data");
for(int i=0;i<dataArray.length();i++){
JSONObject json_data = dataArray.getJSONObject(i);
String category_id = json_data.getString("category_id");
String name = json_data.getString("name");
String count = json_data.getString("count");
}

Look into the Gson library by Google. It's easier than parsing the fields manually with the included JSON lab.
How to parse HTTP response ton JSON object ?
I changed my json code to:
{
"data": [{
"id": 1,
"sensor1": 76,
"sensor2": 75
}, {
"id": 2,
"sensor1": 76,
"sensor2": 206
}]
}
And my code is now:
JSONObject json = new JSONObject(mJson);
try {
data = json.getJSONArray("data");
for (int i = 0; i < json.length(); i++) {
HashMap<String, Integer> map = new HashMap<String, Integer>();
JSONObject obj = (JSONObject) data.get(i);
map.put(TAG_SENSOR_1, obj.getInt("sensor1"));
map.put(TAG_SENSOR_2, obj.getInt("sensor2"));
dataList.add(data.getInt("id") - 1, map);
}
} catch (JSONException e) {
e.printStackTrace();
}
But I have the same problem
edit your string to this format
{content:[{
first:1,
second:76,
third:75
},
{
first:2,
second:76,
third:75
},
{
first:3,
second:206,
third:75
},
{
first:4,
second:6,
third:175
},
{
first:5,
second:176,
third:75
}]
}
then use JSONObject and JSONArray to convert string
JSONArray array = new JSONObject(string).getJSONArray("content");
for(int i=0;i<array.size();i++){
JSONObject obj = array.get(i);
Log.i(TAG,"obj.getInt = "+obj.getInt("first"));
Log.i(TAG,"obj.getInt = "+obj.getInt("second"));
Log.i(TAG,"obj.getInt = "+obj.getInt("third"));
}
