The Category object is not present inside the Json file
you can try following
JSONObject json = new JSONObject("str");
JSONObject data = json.getJSONObject("data");
JSONArray school = json.getJSONArray("school");
for (int i = 0; i < data.length(); i++) {
JSONObject object = school.getJSONObject(i);
long id = Long.parseLong(object.getString("id"));
String name = object.getString("name");
JSONObject category = new JSONObject();
category.put("id");
category.put("name");
}
First you need to fetch an OBJECT of the whole JSON because it's in '{' '}'. Then you need to fetch an object again with the name "data" because it is in '{' '}'. And only then should you fetch the array named "school".
JSONObject json = new JSONObject(str);
JSONObject data = json.getJSONObject("data");
JSONArray school = data.getJSONArray("school");

Yes .There is an error.Your JSON Data has An array inside array and you are trying to assign internal array as object.
First convert outer array JsonArray jsonArray1;
Iterate through this array. i=0 -> jsonArray1.length; and create another
JsonArray jsonArray2 = jsonArray1[i];
And finally iterate through jsonArray2: j=0 -> jsonArray2.length()
and create a JsonObject json = jsonArray2[j];

Whats the reason for this?please Help me
Response is not a JSON object ,it's a JSON array with one element.
JSONArray a = new JSONArray("[{your JSON code}]");
JSONObject = a.getJSONObject(1);
In the following line, 'data' returns a JSON Array not a String. (Since it is enclosed in [])
jObject = new JSONObject(jObject.getString("data"));
So you'll need to get the jsonArray first.
JSONArray jArray = jObject.getJSONArray("data");
Then get the first object from the array.
JSONObject dataObject = jArray.getJSONObject(0);
now fetch the String.
String pushStatus = dataObject.getString("push_status");
I am facing some problem while parsing JSON values, Please find the JSON file below,
{
"Account": "xxx",
"Account_desc": "xxx",
"TimeZone": "GMT+05:30",
"DeviceList": [
{
"Device": "xttt",
"Device_desc": "txtx",

},
{
"Device": "pppp",
"Device_desc": "statstr",
"EventData": [
{

"Timestamp": 1368870217,
"Timestamp_date": "2013/05/18",
"Timestamp_time": "15:13:37",
"StatusCode": 61715,

"Odometer_units": "Km",
"Geozone": "port",
"Geozone_index": 0,
"Address": "asdfsdfss",
"Index": 0
}
]
}
]
}
From the above JSON , I would like to have only "GPSPoint_lat","GPSPoint_lon" and "Device" in "EventData" So I did the coding as follows,
JSONObject jsonObject = ApplicationContext.getHttpService()
.readAsJson(s);
// System.out.println("indexvalue:"+s.indexOf(1,5));
// JSONObject object = jsonObject.getJSONObject("DeviceList");
JSONArray jsonArray = jsonObject.getJSONArray("DeviceList");
JSONObject object = jsonArray.getJSONObject(0);
JSONArray secondarray = object.getJSONArray("EventData");
for (int i = 0; i < secondarray.length(); i++) {
try {
System.out.println("Im...");
// System.out.println("Latitude:"+ ((JSONObject)
// jsonArray.get(i)).getString("GPSPoint_lat"));
// String id = ((JSONObject)
// jsonArray.get(i)).getString("deviceID");
// arr = (JSONArray) jsonArray.get(i);
JSONObject obj = secondarray.getJSONObject(i);
String lat = obj.getString("GPSPoint_lat");
String lon = obj.getString("GPSPoint_lon");
........//..
...///......}}
But problem in the above code is whenever I am executing I am getting the arraylength is 1, i.e., getting only one value I mean first Eventdata values. What i need in this is I would like to get all the "Eventdata" values. Please suggest me regarding this.
Regards
Priya
JSONObject object = jsonArray.getJSONObject(0);
I am guessing at this point in the above code you are just fetching the data at the first index which is specified by '0'. Hence you get the length also as one. Try doing the object.getJSONArray() inside the loop with the index. Maybe that will help you get all the data inside "EventData". Hope this helps :)
Try this..
JSONArray jsonArray = jsonObject.getJSONArray("DeviceList");
for (int j = 0; j < jsonArray.length(); j++) {
JSONObject object = jsonArray.getJSONObject(j);
JSONArray secondarray = object.getJSONArray("EventData");
for (int i = 0; i < secondarray.length(); i++) {
System.out.println("Im...");
// System.out.println("Latitude:"+ ((JSONObject)
// jsonArray.get(i)).getString("GPSPoint_lat"));
// String id = ((JSONObject)
// jsonArray.get(i)).getString("deviceID");
// arr = (JSONArray) jsonArray.get(i);
JSONObject obj = secondarray.getJSONObject(i);
String lat = obj.getString("GPSPoint_lat");
String lon = obj.getString("GPSPoint_lon");
}
}
For JSON parsing use following class.
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONObject;
public class JSONParser {
public JSONParser() {
}
JSONObject jObj;
String json;
InputStream is = null;
public JSONObject getJsonFromUrl(String url) {
// TODO Auto-generated method stub
try {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (Exception e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
System.out.println("Json String : " + json);
} catch (Exception e) {
e.printStackTrace();
}
try {
jObj = new JSONObject(json);
} catch (Exception e) {
e.printStackTrace();
}
return jObj;
}
}
and in your MainActivity use following code to parse it.
JSONParser parser = new JSONParser();
JSONObject o = parser.getJsonFromUrl("yourjsonurl");
String Account = o.getString("Account");
String Account_desc = o.getString("Account_desc");
JSONArray array = o.getJSONArray("DeviceList");
JSONObject o1 = array.getJSONObject(0);
String Device = o1.getString("Device");
//Again you have JSONArray
JSONArray a = o1.getJSONArray("EventData");
//Then get object form array at index 0.
JSONObject obj = a.getJSONObject(0);
Then get your data from this json object.
The problem in your JSON is that in eventData array you have 1 JSON object with alot of mappings and not allot of jsonObjects. If you wannt EventData to be a JSONArray with all
.."Geozone": "zone4",
"Geozone_index": 0,
"Address": "cxcxc",
"DigitalInputMask": 251,
"DigitalInputMask_hex": "0xFB",
"Index": 0...
as JsonObject you need yo change the JSON to be as an array
..{"Geozone": "zone4"},
{"Geozone_index": 0},
{"Address": "cxcxc"},
{"DigitalInputMask": 251},
{"DigitalInputMask_hex": "0xFB"},
{ "Index": 0}
...
JSONArray DeviceListArray = jsonObject.getJSONArray("DeviceList");
for (int i = 0; i < DeviceListArray.length(); i++) {
JSONObject Deviceobject = DeviceListArray.getJSONObject(i);
JSONArray EventDataArray = Deviceobject.getJSONArray("EventData");
for (int j= 0; j < EventDataArray.length(); j++) {
JSONObject valueObj = EventDataArray.getJSONObject(j);
String GPSPoint_lat = valueObj.getString("GPSPoint_lat");
String GPSPoint_lon = valueObj.getString("GPSPoint_lon");
String Device = valueObj.getString("Device");
// Store this three values in ArrayList
}
}
}
Priya, Your json contains three objects and two arrays as follows
Objects
1. Entire response
2. DeviceList
3. EventData
Arrays
Device List - holds arrays of devices
Event Data - Arrays of events
Now carefully look your JSON, that json contains N number of Devices but every device has one event, So you have to iterate DeviceList and then iterate event list.
So that iteration should as follows.
JSONObject jsonObject = ApplicationContext.getHttpService().readAsJson(s);
JSONArray jsonDeviceListArray = jsonObject.getJSONArray("DeviceList");
int deviceCount = jsonDeviceListArray.length();
JSONObject jsonDeviceObj;
JSONArray jsonEventList;
for (int deviceIndex = 0; deviceIndex < deviceCount; deviceIndex++) {
jsonDeviceObj = jsonDeviceListArray.getJSONObject(deviceIndex);
//Here you can print device, device_desc from jsonDeviceObj
jsonEventList = jsonDeviceObj.getJSONArray("EventData");
int eventCount = jsonEventList.length();
JSONObject jsonEventObj;
for (int eventIndex = 0; eventIndex < eventCount; eventIndex++) {
jsonEventObj = jsonEventList.getJSONObject(eventIndex);
//Here you can print event info.
}
}
You have missing "" in your json data. All numbers should have "", as before parsing it is treated as string.

Parsing JSON Object in Java [duplicate]

Closed 8 years ago.
I am retrieving JSON data and store it in array for using.
I get the json data by:-
Uri uri = new Uri.Builder().scheme("http").authority().path().build();
System.out.println("uri of category is : -"+uri);
URI u = new URI(uri.toString());
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(u);
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
is = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is),8);
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line="0";
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
but my json is some other type. so i am confuse how to get and store in my arraylist.
{
employee: [
{
name: "ajay",
id: 1,
},
{
name: "rajiv",
id: 2,
}
],
address: [
{
city: "bombay",
pin: 114141
}
]
}
I know that there is first JSONObject and having two jsonarray. but how can i retrive it.
JSONArray jsonArray = jObject.getJSONArray("employee");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
modelJSon.setname(jsonObject.getString("name"));
modelJSon.setid(jsonObject.getString("id"));
modelList.add(modelJSon);
modelJSon = new ModelBroker();
}
JSONArray jsonArray = jObject.getJSONArray("address");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
modelJSon.setcity(jsonObject.getString("city"));
modelJSon.setpin(jsonObject.getString("pin"));
modelList.add(modelJSon);
modelJSon = new ModelBroker();
}
JSONObject json = new JSONObject(String jsonString);
JSONArray employeesArray = json.getJSONArray("employee");
final int arrayLength = employeesArray.length();
for (int i = 0; i< arrayLength; i++) {
JSONObject employeeJson = array.getJSONObject(i);
// parse employee JSON and add it to your ArrayList
}
Do likewise with the other array.
You can use this
JSONObject jObject = new JSONObject(jsonString);
JSONArray jArray = jObject.getJSONArray("employee");
JSONObject jo;
for(int i=0;i<jArray.length();i++){
jo = jArray.getJSONObject(i);
Log.d("name", jo.getString("name"));
Log.d("id", jo.getString("id"));
}
jArray = jObject.getJSONArray("address");
for(int i=0;i<jArray.length();i++){
jo = jArray.getJSONObject(i);
Log.d("city", jo.getString("city"));
Log.d("pin", jo.getString("pin"));
}
I want to get data from a jason webservice,
JSON response is :
{"content":[{"id":"1","asset_id":"62","title":"sample page","alias":"","introtext":"","fulltext":"Some Contents"},{"id":"2","asset_id":"62","title":"sample page2","alias":"","introtext":"","fulltext":"Some Contents"},{"id":"3","asset_id":"62","title":"sample page3","alias":"","introtext":"","fulltext":"Some Contents"}]}
After Visiting Here
I have done in this way:
private void parseData() {
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(BASE_URL);
try {
// Getting Array of Contents
contents = json.getJSONArray(TAG_CONTENTS);
// looping through All Contents
for(int i = 0; i < contents.length(); i++){
JSONObject c = contents.getJSONObject(i);
// Storing each json item in variable
id = c.getString(TAG_ID);
title = c.getString(TAG_TITLE);
}
textView.setText(id + " " + title);
} catch (JSONException e) {
e.printStackTrace();
}
}
Now I got id = 3 and title = sample page3result now how can I get first two values as also!!?
Arshay!! Try This One Man!!
private void parseData() {
// Creating JSON Parser instance
MyJSONParser jParser = new MyJSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(BASE_URL);
try {
// Getting Array of Contents
jsonArrar = json.getJSONArray(TAG_CONTENTS);
List list = new ArrayList<String>();
// looping through All Contents
for(int i = 0; i < jsonArrar.length(); i++){
// JSONObject c = jsonArrar.getJSONObject(i);
String id1=jsonArrar.getJSONObject(i).getString(TAG_ID);
String title=jsonArrar.getJSONObject(i).getString(TAG_TITLE);
String fullText=jsonArrar.getJSONObject(i).getString(TAG_FULL_TEXT);
list.add(id1);
list.add(title);
list.add(fullText);
}
Iterator<String> iterator = list.iterator();
StringBuilder builder = new StringBuilder();
while (iterator.hasNext()) {
String string = iterator.next();
builder.append(string+"\n");
}
textView.setText(builder);
} catch (JSONException e) {
e.printStackTrace();
}
}
Your line is JSONObject and not JSONArray.
You should use it like that:
JSONObject jso = new JSONObject(line);
JSONArray jsa = new JSONArray(jso.getJSONArray("content"));
Try something like this
// jsonData : response
List< String> contents = new ArrayList< String>();
String[] val;
try {
JSONObject jsonObj = new JSONObject(jsonData);
if (jsonObj.get(JSON_ROOT_KEY) instanceof JSONArray) {
JSONArray array = jsonObj.optJSONArray(JSON_ROOT_KEY);
for (int loop = 0; loop < array.length(); loop++) {
val = new String[loop];
JSONObject Jsonval = array.getJSONObject(loop);
val.Jsonval.getString(TAG_ID);
val.Jsonval.getString(asset_id);
.
.
etc
contents.add(val);
}
}
}
