I have JSON data like this,it is having multiple jsonArrays in it.how to parse this type of data?
{
"result":
[{
"site_name":"comenius",
"ws_url":"https://comenius-api.sabacloud.com/v1/",
"base_url":"https://comenius.sabacloud.com/",
"logo_url":"",
"Title":"",
"menu_items":[
{"item":
[{"id":"home1","label":"Home" }]
},
{"item":
[{"id":"enrol1","label":"Enrollment" }]
},
{"item":
[{"id":"transcripts1","label":"Completed Courses"}]
},
{"item":
[{"id":"goals1","label":"Goals"}]
},
{"item":
[{"id":"rprojects1","label":"Reference Projects"}]
},
{"item":
[{"id":"iwh1","label":"Internal Work History"}]
},
{"item":
[{"id":"ewh1","label":"EXternal Work History"}]
}
]
},{.....}
]
}
i need to parse the data and get the values of id,label ,i write some code to parse the data but it didnt work.
JSONObject subObj = new JSONObject(data2);
JSONObject innerObj1 = subObj.getJSONObject("result");
JSONObject subArrayObj = innerObj1.getJSONObject("menu_items");
for(int j =0;j < subArrayObj.length();j++) {
JSONObject innsersubObj = subArrayObj.getJSONObject("item");
String id = innsersubObj.getString("id");
String label = innsersubObj.getString("label");
Log.e("id",id);
Log.e("label",label);
}
How to parse the data any thing need to change in the code ?
You have to use JSONObject and JSONArray are different objects, you have to use correct class:
JSONArray resultArray = subObj.getJSONArray("result");
JSONObject firstItem = resultArray.getJSONObject(0);
JSONArray menuItems = firstItem.getJSONArray("menu_items");
etc.
JSONARRAY subArrayObj = innerObj1.getJSONARRAY("menu_items");
Since menu_items is returning an array..it should be collected in an array object..

I am calling a REST API using the android app, the results of the POST method API is as follows:
{
"Items": {
"ap_id": "37",
"ap_time_from": "14:28",
"ap_time_to": "16:28",
"patient_id": "153",
"patient_name": "Nikhil",
"patient_email": "a#a.com",
"patient_location": "abc"
} }
Converting it into readable data using:
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("Items");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject object = jsonArray.getJSONObject(i);
DoctorModel doctorModel1 = new DoctorModel();
doctorModel1.setApp_id(object.getString("ap_id"));
doctorModel1.setStart_timing(object.getString("ap_time_from"));
doctorModel1.setEnd_timing(object.getString("ap_time_to"));
doctorModel1.setUser_id(object.getString("patient_id"));
doctorModel1.setUser_name(object.getString("patient_name"));
doctorModel1.setUser_mail(object.getString("patient_email"));
doctorModel1.setLocation(object.getString("patient_location"));
doctorModelList.add(doctorModel1); }
Now when I am trying to convert it so that I can display the results in a recycler view I am getting the following error:
org.json.JSONException: Value
{"ap_id":"37","ap_time_from":"14:28","ap_time_to":"16:28","patient_id":"153","patient_name":"Nikhil","patient_email":"a#a.com","patient_location":"abc"}
at Items of type org.json.JSONObject cannot be converted to JSONArray
I have been using the same way of converting the JSON Object data into JSON Array, not sure where I am going wrong. Any help would be appreciated, thanks!
You need to have an array as an object inside Items, as follows :
{
"Items":
[
{
"ap_id": "37",
"ap_time_from": "14:28",
"ap_time_to": "16:28",
"patient_id": "153",
"patient_name": "Nikhil",
"patient_email": "a#a.com",
"patient_location": "abc"
}
]
}
Else, change your code to support single object instead of an array
JSONObject jsonObject = new JSONObject(response);
JSONArray object = jsonObject.JSONObject("Items");
In the current response, the value of Items has a JSON object, not a JSON array. That's why this exception happens. To convert this response to data model then you can use this:
JSONObject jsonObject = new JSONObject(response);
JSONArray object = jsonObject.JSONObject("Items");
DoctorModel doctorModel1 = new DoctorModel();
doctorModel1.setApp_id(object.getString("ap_id"));
doctorModel1.setStart_timing(object.getString("ap_time_from"));
doctorModel1.setEnd_timing(object.getString("ap_time_to"));
doctorModel1.setUser_id(object.getString("patient_id"));
doctorModel1.setUser_name(object.getString("patient_name"));
doctorModel1.setUser_mail(object.getString("patient_email"));
doctorModel1.setLocation(object.getString("patient_location"));
doctorModelList.add(doctorModel1);
Or if you want to get the array from json then the JSON will look like this:
{
"Items":
[
{
"ap_id": "37",
"ap_time_from": "14:28",
"ap_time_to": "16:28",
"patient_id": "153",
"patient_name": "Nikhil",
"patient_email": "a#a.com",
"patient_location": "abc"
}
]
}
Hope you understand the isse.
JSONArray jsonArray = jsonObject.getJSONArray("Items"); // this line getting exception because you are trying to convert JSONObject("Items") into JSONArray.
you have to make some changes in the response: 1. If you want to return "Items" as Array in Response.
{
"Items": [
{
"ap_id": "37",
"ap_time_from": "14:28",
"ap_time_to": "16:28",
"patient_id": "153",
"patient_name": "Nikhil",
"patient_email": "a#a.com",
"patient_location": "abc"
}
]
}
If you want to return "Items" like an object in Response then you have to change in code like this
JSONObject jsonObject = new JSONObject(response);
JSONObject jsonObjectItem = jsonObject.getJSONObject("Items");
But in the second case, you can not get the result in the form of an array.
1.I am having json object like this how can i get the access to all values in android
2.before anyone down voting that i want to say i have searched stackoverflow for similar examples but those examples contains JSONObject and then JSONArray
3.Here in my case everything is JSONObject so i'm little bit confused
{
"1":
{"sno":"10","latitude":"31.249441437085455","longitude":"75.70003598928452"},
"2":
{"sno":"11","latitude":"31.249398442090207","longitude":"75.70003397762775"}
}
This is how i made it to JSONObject
1.Below code returned me output like that which is all JSONObject
2.Is there any way to make "1" and "2" as JSONArray ?
$select_rows = "select sno,latitude,longitude from activities where username='$username'";
if ($result = mysql_query($select_rows)) {
$num_of_fields = mysql_num_fields($result);
$num_of_rows = mysql_num_rows($result);
$i = 0;
$j = 1;
while ($retrieved = mysql_fetch_array($result)) {
for ($i = 0; $i < $num_of_fields; $i++) {
$field_name = mysql_field_name($result, $i);
$object[$j][$field_name] = $retrieved[$field_name];
}
$j++;
}
echo json_encode($object);
}
Hope this may help you
JSONObject jsonObject=new JSONObject(result);
jsonObject=jsonObject.getJSONObject("1");
Double lat=jsonObject.getDouble("latitude");
Toast.makeText(getBaseContext(),""+ lat, Toast.LENGTH_LONG).show();
Better create a valid JSONArray to make things easier. When you create the JSON string , don't append the index. I believe your are reading the data from sqlite and generating the JSON string.
Also change the outer { (curly brace) to [ (square bracket) to represent as Array element. So your json string will be like this
[
{
"sno": "10",
"latitude": "31.249441437085455",
"longitude": "75.70003598928452"
},
{
"sno": "11",
"latitude": "31.249398442090207",
"longitude": "75.70003397762775"
}
]
Then , you can simply get its as JSONArray
JSONArray jsonArray = new JSONArray(jsonString);
And then read each element in array item
for(int index = 0;index < jsonArray.length(); index++) {
JSONObject jsonObject = jsonArray.getJSONObject(index);
}
To get one of your inner JSONObject elements, you'll need to get it from the outer one using getJSONObject(String key).
Sample code:
JSONObject item1 = myJson.getJSONObject("1");
//item1 now contains {sno:10,latitude:31.2...etc}
//now you can get the individual values out of the resulting JSON Object
//for example, getting the latitude
double lat = item1.getDouble("latitude");
Hey guys this is the first time I am doing JSON and I have gotten the json from the server. Now my only question is how do I take the data.
The JSON includes
[
{
"name": "Joe Smith",
"employeeId":1,
"company": "ABC",
"phone": {
"work": "555-555-5555",
"home": "666-666-6666",
"mobile": "777-777-7777"
}
},
{
"name": "Does Smith",
"employeeId":2,
"company": "XYZ",
"phone": {
"work": "111-111-1111",
"home": "222-222-2222",
"mobile": "333-333-3333"
}
}
]
jsonData is my string of the JSON
Currently I have:
JSONObject json = new JSONOBject(jsonData);
JSONObject data = json.getJSONObject(*******)
JSONArray phones = data.getJSONArray("phone");
not sure what to put on the second line. Also, what is the best way to group the information.
Please make it easy to understand, not exactly a professional yet haha
Thanks!
Your first line is wrong because current string is JSONArray of JSONObject's so get data from current string as:
JSONArray json = new JSONArray(jsonData);
for(int i=0;i<json.length();i++){
JSONObject data = json.getJSONObject(i);
// get name,employeeId,... from data
String str_name=data.optString("work");
//...
JSONObject jsonobjphones = data.getJSONObject("phone");
// get work from phone JSONObject
String str_work=jsonobjphones.optString("work");
//....
}
Try this
List list=new ArrayList();
JSONObject jObject = new JSONObject(str_response_starter);
JSONArray json_array_item_id = jObject.getJSONArray("itemid");
System.out.println("json array item id"+json_array_item_id);
JSONArray json_array_item_name = jObject.getJSONArray("itemname");
System.out.println("json array item name"+json_array_item_name);
JSONArray json_array_item_type = jObject.getJSONArray("type");
System.out.println("json array item type"+json_array_item_type);
JSONArray json_array_item_cost = jObject.getJSONArray("cost");
System.out.println("json array item cost"+json_array_item_cost);
Now
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(kvPairs.size());
String k, v;
Iterator<String> itKeys = kvPairs.keySet().iterator();
while (itKeys.hasNext()) {
k = itKeys.next();
System.out.println(" value of k"+k);
v = kvPairs.get(k);
System.out.println(" value of v"+v);
In JSON, [] represents JSONArray, {} represents JSONObject. In your JSON string, it starts with [, so you need to start with JSONArray:
JSONArray people = new JSONArray(jsonData);
And then you'll notice that each person is a JSONObject, so now you need to loop them in order to get their information:
for(int i=0;i<people.length();i++){
JSONObject person = people.getJSONObject(i);
JSONObject phones = person.getJSONObject("phone"); //phone is also a JSONObject, because it starts with '{'
String workPhone = phones.get("work");
}
So I am receiving a JSON array in an httpresponse. The array consists of the following objects/variables.
{"sessid":"vxkEXkMBUmBByESRlvaxrxSaFTfhDqd8","session_name":"SESS88cdfb2f1c420898","user":{"uid":"60","name":"abc","theme":"","signature":"","signature_format":"filtered_html","created":"13082976","access":"1386287","login":1386211,"status":"1","timezone":null,"language":"","picture":null,"data":{"mimemail_textonly":0},"roles":{"2":"authenticated user","5":"centre user"},"field_centre_reference":{"und":[{"nid":"256"}]},"field_first_name":{"und":[{"value":"web","format":null,"safe_value":"web"}]},"field_surname":{"und":[{"value":"services","format":null,"safe_value":"services"}]},"bounce_mail_blocked":false,"force_password_change":"0"}}
Now I want to receive all these objects/strings in separate variables. Like i want to store the "sessid" in a variable String session_id. And so on. I can get the first two (i.e. sessid and session_name) in a simple way with the help of the following code.
response = client.execute(httppost);
BasicResponseHandler handler = new BasicResponseHandler();
String data = handler.handleResponse(response);
jObj = new JSONObject(data);
sessid = jObj.getString("sessid");
Log.d("sessid obj", sessid);
session_name = jObj.getString("session_name");
Log.d("session_name", session_name);
But since I am a noob at Android, I don't know how to get the rest of the data to be saved in variables. The upcoming data cannot be saved in a simple way.
Try with this:
JSONObject j_user = jObj.getJSONObject("user");
String uid = j_user.getString("uid");
...
//And so on with the rest of the fields
{ // json object node
"sessid": "vxkEXkMBUmBByESRlvaxrxSaFTfhDqd8",
"session_name": "SESS88cdfb2f1c420898",
"user": { // json object user
"uid": "60", // string
"name": "abc",
"theme": "",
"signature": "",
"signature_format": "filtered_html",
"created": "13082976",
"access": "1386287",
"login": 1386211,
"status": "1",
"timezone": null,
"language": "",
"picture": null,
"data": { // json object data
"mimemail_textonly": 0 //string
},
....// rest of the json
{ represents json object node
[ represents json array node
To parse
JSONObject jObj = new JSONObject(load());
String sessid = jObj.getString("sessid");
Log.d("sessid obj", sessid);
JSONObject user = jObj.getJSONObject("user");
String uid = user.getString("uid");
Log.d("sessid obj", uid);
To parse data
"data": {
"mimemail_textonly": 0
},
JSONObject data= user.getJSONObject("data");
Log.i(".......",""+data.getString("mimemail_textonly"));
To parser field_centre_reference
"field_centre_reference": { // json object field_centre_reference
"und": [ // json array und
{ // json object node
"nid": "256" //string
}
]
},
JSONObject field= user.getJSONObject("field_centre_reference");
JSONArray jr = field.getJSONArray("und");
JSONObject jb1 = (JSONObject) jr.get(0);
Log.i(".......",""+jb1.getString("nid"));
Check out JacksonParser library, it provides annotations which make your work so easy. And it is one of fastest parsing libraries... You can have it here
Edit:
As an example you can take a look at one of my previous question JacksonParser databind and core cause "Found duplicate file for APK"?
You should notice that the JSON you received is a nested JSON. It is like a Map that one of the value of Map is also a Map.
In your case, there is a JSONObject contains sessid and session_name while is only string, but the "user" is also a JSONObject, so you can parse it level by level.
For more details, you can read http://www.vogella.com/articles/AndroidJSON/article.html
Try this..
Getting
"user": {
"uid": "60",
JSONObject obj_user = jObj.getJSONObject("user");
String uid = obj_user.getString("uid");
"user": {
"uid": "60",
"data": {
"mimemail_textonly": 0
}
JSONObject obj_data = jObj.getJSONObject("data");
String mimemail_textonly = obj_user.getString("mimemail_textonly");
JSONObject obj_roles = jObj.getJSONObject("roles");
String two = obj_roles.getString("2");
"field_centre_reference": {
"und": [
{
"nid": "256"
JSONObject obj_field_centre_reference = jObj.getJSONObject("field_centre_reference");
JSONArray ary_und = obj_field_centre_reference.getJSONArray("und");
JSONObject objve = ary_und.getJSONObject(0);
String nid= objve.getString("nid");
I have JSON object as follows:
[
{
"Project": {
"id": "1",
"project_name": "name"
},
"AllocationDetail": [
{
"id": "1",
"project_id": "1",
"team_name": "ror",
"week_percentage_work": "50",
"in_today": "1",
"actual_hours": "30",
"remaining_hours": "100",
"time_difference": null,
"created": "2012-01-13 15:48:33",
"modified": "2012-01-13 15:48:33"
},
{
"id": "2",
"project_id": "1",
"team_name": "php",
"week_percentage_work": "40",
"in_today": "2",
"actual_hours": "50",
"remaining_hours": "100",
"time_difference": null,
"created": "2012-01-13 15:49:40",
"modified": "2012-01-13 15:49:40"
}
]
}
]
I want to parse data in android and store it into DB, but i m getting confused in Jsonobject
thanks
the best JSON Tutorial i have seen, I leared json parsing from this tutorial, hope it will help
The following is a snippet code for parsing your json string. Kindly go through it:
String response = <Your JSON String>;
String Project = null;
String AllocationDetail = null;
try {
JSONArray menuObject = new JSONArray(response);
for (int i = 0; i< menuObject.length(); i++) {
Project = menuObject.getJSONObject(i).getString("Project").toString();
System.out.println("Project="+Project);
AllocationDetail = menuObject.getJSONObject(i).getString("AllocationDetail").toString();
System.out.println("AllocationDetail="+AllocationDetail);
}
JSONObject jsonObject = new JSONObject(Project);
String id = jsonObject.getString("id");
System.out.println("id="+id);
String project_name = jsonObject.getString("project_name");
System.out.println("project_name="+project_name);
JSONArray jArray = new JSONArray(AllocationDetail);
for (int i = 0; i< jArray.length(); i++) {
String team_name = jArray.getJSONObject(i).getString("team_name").toString();
System.out.println("team_name="+team_name);
String week_percentage_work = jArray.getJSONObject(i).getString("week_percentage_work").toString();
System.out.println("week_percentage_work="+week_percentage_work);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
There are two ways for parsing JSON
Google GSON
JSON
When your content of JSON is too complex and long enough you can prefer usin GSON its much easier to maintain than JSON parsing each value manually.
Use jsonlint.com to read your json better. It appears that the json that you have copied here is invalid.
String response = <Your JSON String>; // add your Json String here
response = response.replace("[","").replace("]",""); // Just remove all square braces
JSONObject json = new JSONObject(response); //Convert the Json into Json Object
JSONObject jProject = json.getJSONObject("Project"); // get your project object
String project_id = jProject.getString("id"); // Get the value of Id
String project_name = jProject.getString("project_name"); // get the value of Project_name
The above code can be use many times as you want to parse the Json.
I know its too late, but It may help many people who are trying to find the same answer.
I was trying to find the same solution, but it was too hard to use the Accepted answer because of too many lines of codes, But I got the same results with hardly few lines of codes.
