I want to get only some selected values from the JSON response.For example if JSON contains 100 string values then i need to take the values which are starting with # symbol from that 100 values.
How can I do that ?
Following is my JSON,
[{"Obj" :
{ "ID":"11",
"NAME":"XYZ",
"GENDER":"M"
}
{ "ID":"11",
"NAME":"#XYZ",
"GENDER":"M"
}
{ "ID":"11",
"NAME":"#XYZ",
"GENDER":"M"
}
}]
Here I need to fetch Name which having # symbol
You can use below method to get the Name which start with # :
JSONObject jsonObject = new JSONObject(response);// u can change it as per your need
JSONArray jArray = jsonObject.getJSONArray("Obj");// if your `Obj` is an JsonArray
for (int i = 0; i < jArray.length(); i++) {
String json_name = jArray.getJSONObject(i).getString("NAME");
if(json_name.startsWith("#"))
{
Log.d(TAG,"It start with #");
}
}
Try out as below:
private void parseJSON(String json) {
try {
JSONArray items = new JSONArray(<your Json Response>);
for (int i = 0; i < items.length(); i++) {
JSONObject item = items.getJSONObject(i);
System.err.println("Object---" + item.getString("Obj"));
JSONObject obj=item.getJSONObject("Obj");
for (int j = 0; j < obj.length(); j++) {
String Name=obj.getString("NAME");
if(obj.getString("NAME").toString().contains("#"))
{
Log.d("Name starts with-->", Name);
}
else
{
Log.d("Name does not start with-->", Name);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Try this.
first of all that's not a valid json may be below json is correct format
[
{
"Obj": [
{
"ID": "11",
"NAME": "XYZ",
"GENDER": "M"
},
{
"ID": "11",
"NAME": "#XYZ",
"GENDER": "M"
},
{
"ID": "11",
"NAME": "#XYZ",
"GENDER": "M"
}
]
}
]
if your response like above try below code this may help you.
try {
JSONArray jsoArray = new JSONArray(json);

Iterator<String> iter = Jobj.keys();
while (iter.hasNext()) {
String key = iter.next();
Log.v("key--", key);
try {
Object value = Jobj.get(key);
Log.v("value--", ""+value);
String str_value = value.toString().trim();
if(str_value.startsWith("#"))
{
Log.d(""+str_value,"value started with #");
}

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
My question is that i have to display my data which is fetched from JSON file ,the json file is below. But i want the data to be in sorted form after getting from JSON file i.e after the rest call when data is obtained from controller in viewmodel,so that i can directly display it on the View Class. which has cardviews.
{
"employeeList":[
{
"employeeName": "aaaa",
"employeeStatus": "Trainee",
"company": "IBM",
"mobile": "894996662"
},
{
"employeeName": "bbbb",
"employeeStatus": "Fellowship",
"company": "Wipro",
"mobile": "9876000021"
},
{
"employeeName": "cccc",
"employeeStatus": "Fellowship",
"company": "CGI",
"mobile": "9876000021"
},
{
"employeeName": "cccc",
"employeeStatus": "Fellowship",
"company": "CGI",
"mobile": "9876000021"
}
]
}
And the .java file is below,were i have not done the sorting.I need the help,Thank you.
try {
//As the data in rest call contained in JSONObject inside that JSONArray and inside
//JSONArray JSONObject is there ,Hence to get the data and set to the Model Class
//Creating JSON Object and obtained the data in bytes
JSONObject jsonObject = new JSONObject(new String(bytes));
Log.i("json object", "employeeList: ");
if (jsonObject != null) {
JSONArray jsonArray = jsonObject.getJSONArray("employeeList");
Log.i("json Array", "employeeList: " + jsonArray.length());
//Creating the object of modelClass
if (jsonArray.length() != 0) {
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject childObject = jsonArray.getJSONObject(i);
//Through the object of model Class the obtained data is set to the
//Model class
EnggFragModel enggFragModel = new EnggFragModel();
enggFragModel.setImageurl(childObject.getString("imageUrl"));
Log.i("image", "employeeData: "+childObject.getString("imageUrl"));
enggFragModel.setEmployeeName(childObject.getString("employeeName"));
enggFragModel.setEmployeeStatus(childObject.getString("employeeStatus"));
enggFragModel.setCompany(childObject.getString("company"));
enggFragModel.setEmployeeMobile(childObject.getString("mobile"));
enggFragModel.setEmployeeEmail(childObject.getString("emailId"));
enggFragModel.setEngineerID(childObject.getString("engineerId"));
Log.i("EngineerId", "employeeData: " + childObject.getString("engineerId"));
enggArrayList.add(enggFragModel);
}
enggViewModelInterface.enggViewMInterface(enggArrayList);
Log.i("Employee", "employeeList: " + enggArrayList);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
Log.i("Employee", "employeeList: ");
The solution is to take JSONArray "employeeList" convert it to ArrayList of JSONObject and sort it, using Collections.
ArrayList<JSONObject> array = new ArrayList<JSONObject>();
JSONArray jsonArray = new JSONArray();
for (int i = 0; i < jsonArray.length(); i++) {
try {
array.add(jsonArray.getJSONObject(i));
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Collections.sort(array, new Comparator<JSONObject>() {
#Override
public int compare(JSONObject lhs, JSONObject rhs) {
// TODO Auto-generated method stub
try {
return (lhs.getString("Name").toLowerCase().compareTo(rhs.getString("Name").toLowerCase()));
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return 0;
}
}
});

How can I loop through this kind of JSON array?
[
{
"full_name": "Abc Xyz"
},
{
"full_name": "Def Xyz"
},
{
"full_name": "Nml Xyz"
},
{
"full_name": "Jol Xyz"
}
]
Thank you!
try this
try {
JSONArray a = new JSONArray(myjsonString);
for(int i = 0; i < a.length(); i++)
{
JSONObject o = a.getJSONObject(i);
String name = o.getString("full_name");
}
} catch (JSONException e) {
e.printStackTrace();
}
Your jsonString contains array of objects so here is code:
try {
// [] indicates array so top element is array
JSONArray jsonArray = new JSONArray(jsonString);
for(int i = 0; i < jsonArray.length(); i++)
{
// {} indicates object so array elements are objects
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name = jsonObject.getString("full_name");
}
} catch (JSONException e) {
e.printStackTrace();
}
Updated : Google GSON
Also try Google's GSON this is excellent library to handle jsons you can serialize and deserialize the json and class objects.
checkout this link: Google Gson
Try
try {
JSONArray array = new JSONArray(jsonString);
for(int i = 0; i < array.length(); i++) {
JSONObject json = array.getJSONObject(i);
String fullName = json.getString("full_name");
}
} catch (JSONException e) {
e.printStackTrace();
}
How can i extract the json below and save it in an arraylist.
{
"trains": {
"train": [
{
"#id": 1000000103,
"#version": 1,
"#status": "active",
"#name": "dffffff",

"#city": "fff",
"#phone": "+230 595-1454",

"localization": []
}
}
]
}
}
my working
try {
jobj_trouve_train = new JSONObject(reponse_trouve_train);
String jsonobj = jobj_trouve_golf.getString("trains");
//String jsonobj1 = jobj_trouve_golf.getString("train");
//jobj_trouve_train = new JSONObject(reponse_trouve_train);
//jsonArray = jobj_trouve_golf.getJSONArray("trains");
//jsonArray= new JSONArray(jsonobj);
//System.out.println("jsonArray "+jsonArray);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Try this..
try {
jobj_trouve_train = new JSONObject(reponse_trouve_train);
JSONObject jsonobj = jobj_trouve_train.getJSONObject("trains");
JSONArray jsonobj1 = jsonobj.getJSONArray("train");
for(int i = 0;i< jsonobj1.length();i++){
JSONObject jsonj = jsonobj1.getJSONObject(i);
System.out.println("#id "+jsonj.getString("#id"));
// Same for remaining all
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
You can use the Gson library developed by Google to parse Json into objects.
The reference is here:
https://code.google.com/p/google-gson/
And, a sample example is here:
JSON Parsing with GSON
JSONObject trains = jobj_trouve_train.getJSONObject("trains");
JSONArray trainArray = trains.getJSONArray("train");
JSONObject train1 = trainArray.getJSONObject(0);
...
if i didn't get confuse maybe this one will be right
JSONArray jasonArray = new JSONArray(result.getProperty("trains").toString());
for (int i = 0; i < jasonArray.length(); i++) {
JSONObject jsonObj = jasonArray.optJSONObject(i);
trainObject = new JSONObject(jsonObj.optString("train").toString());
int id = trainObject.optInt("id");
and so on..
}
public Object void toObject(String jsonMsg) throws JSONException {
JSONObject trains= (JSONObject) new JSONTokener(jsonMsg).nextValue();
if(trains.has("trains")){
JSONArray train = (JSONArray) new JSONTokener(object.getString("train")).nextValue();
for (int t = 0; t < jsonArray.length(); t++) {
String temp = jsonArray.getJSONObject(t).toString();
JSONObject object = (JSONObject) new JSONTokener(temp).nextValue();
if(object.has("#id"))
object.getString("#id");
// now similar procedure of reading
// read values and save it in an "object"
}
return savedObject;
}
-- tested, i have tried to modify code to match your JSON data. complete the rest.
