JSONObject json_data = null;
for (int i1 = 0; i1 < jArray.length(); i1++) {

}
}
int previous = 0;
if (!json2.isNull("tag9")) {

return json;

}
i get only last record ,how do i get all data .any help will be appreciated thanks...
You can try to parse your string # http://json.parser.online.fr/ it works nice for me.
From static review of the JSON string it seems you have "tag" element 3 times in your input and due to that parser might get confused. Try to remove duplicate entries and then try.
The JSONOject has a constructor that accepts a string of JSON data. You can use the constructor to parse the JSON string. If the string is valid JSON data, the constructor will return a JSONObject. If the string is NOT valid JSON, the constructor will throw an error. It's good practice to wrap the constructor inside of a try/catch block.
String json = "{name:\"value\"}";
JSONObject item = null;
try{
item = new JSONObject(json);
}catch(Exception exc){
Log.d(TAG, exc.toString());
}
if(item != null){
Log.d(TAG, String.format("name:%s", item.getString("name")));
}

My code on android to process array, problem in my code on function "for" before I copy and edit another code from file :
JSONObject jsonObjsko = new JSONObject(rajaongkir);
String resultse = jsonObjsko.getString("results");
JSONArray jsonObjssto = new JSONArray(resultse);
JSONObject mJsonObject = jsonObjssto.getJSONObject(0);
costs = mJsonObject.getString("costs");
JSONArray jsonArray = new JSONArray(costs);
for (int k = 0; k < jsonArray.length(); k++) {
try {
JSONArray jsonArrayp = new JSONArray(costs);
JSONObject jsonObject = jsonArrayp.getJSONObject(k);
String serviceq = jsonObject.getString("cost");
String servicel = jsonObject.getString("service");
kon = String.valueOf(jsonArray.length());
kin = kin + k;
JSONArray jsonObjsstorng = new JSONArray(serviceq);
JSONObject mJsonObjectrng = jsonObjsstorng.getJSONObject(k);
String values = mJsonObjectrng.getString("value");
ShipPerActiv wp = new ShipPerActiv(servicel, values);
arraylist.add(wp);
}
catch (JSONException e) {
e.printStackTrace();
}
}
This code for ShipPerActiv for add arraylist :
public class ShipPerActiv {
private String services;
private String hongkir;
public ShipPerActiv(String services,String hongkir) {
this.services = services;
this.hongkir = hongkir;
}
public String getservices() {return this.services; }
public String gethongkir() {return this.hongkir; }
}
I tried use harddebug with kon & kin true function for normal but not on my listview just one int(0) not int(1)~etc
At first convert your StringObject to JSONObject and dont forget to add { at first of string and } to end of string:
JSONObject parentObject = new JSONObject("{"+"JsonString"+"}");
Then parse your object like this :
try {
JSONObject parentObject = new JSONObject(a);
JSONArray results = parentObject.getJSONArray("results");
JSONObject resultsObject=results.getJSONObject(0);
JSONArray costsArray = resultsObject.getJSONArray("costs");
for (int i = 0; i < costsArray.length(); i++) {
Log.d("CostsJsonObject" , costsArray.getJSONObject(i).toString());
}
} catch (JSONException e) {
Log.d("CostsJsonObject Exception" , e.toString());
}
And result :
I think your problem is on this code :
JSONObject mJsonObjectrng = jsonObjsstorng.getJSONObject(k);
Simply change it to :
JSONObject mJsonObjectrng = jsonObjsstorng.getJSONObject(0);
Hope it'll help you ;)

Json Response ,how to extract all things :
[{"category":1,"no_score":3,"question":"Does he ever send the first text of a conversation?","yes_score":1},{"category":1,"no_score":3,"question":"Does he reply with two or three word answers?","yes_score":1}]
Above is json response.. i want to extract each and everything..i.e category,no_score,yes_score and question..
i have tried
question = jsonObj.getString("question");
but i am not getting.. can anyone help me to extract.
Json object start with { and json array starts with [. In your case the json is an array.
So read it as an array instead of jsonobject.
i.e, you need to read it like below.
JSONArray jsonArray = new JSONArray(myjsonstring);
and iterate through the array and read each values.
Your for loop looks fine.
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObj = jsonArray.getJSONObject(i);
question = jsonObj.getString("question");
int no_score = jsonObj.getInt("no_score");
int yes_score = jsonObj.getInt("yes_score");
int category = jsonObj.getInt("category");
tvBoyGirl.setText(question);
}
This is what i do after all things
ListQuestion();
tvQuestionText.setText(questions.get(i));
imUp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
i++;
question_counter++;
tvQuestionCounter.setText(String.valueOf(question_counter));
if (!questions.isEmpty()) {
tvQuestionText.setText(questions.get(i));
if (yes_Score1.get(i) == -1) {
score = score - 1;
} else {
score = score + yes_Score1.get(i);
}
System.out.println(score);
Log.d("yes_per", String.valueOf(score));
counter++;
if (counter == 25) {
calculation();
}
}
}
});
imDown.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
i++;
question_counter++;
tvQuestionCounter.setText(String.valueOf(question_counter));
if (!questions.isEmpty()) {
tvQuestionText.setText(questions.get(i));
if (no_Score1.get(i) == -1) {
score = score - 1;
} else {
score = score + no_Score1.get(i);
}
Log.d("no_per", String.valueOf(score));
System.out.println(score);
counter++;
if (counter == 25) {
calculation();
}
}
}
});
}
Try this:
JSONArray jArray = new JSONArray(jsonString);
for(int i=0;i<jArray.length();i++)
{
JSONObject jObj = jArray.getJSONObject(i);
question = jObj.getString("question");
int no_score = jObj.getInt("no_score");
int yes_score = jObj.getInt("yes_score");
int category = jObj.getInt("category");
}
I want to get two json array from remote url
I am using AsyncTask to do that but i can't get any data !
#Override
protected Void doInBackground(String... params) {
try {
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
String json = jParser.getJSONFromUrl(params[0]);
// Getting Array of Contacts
data = new JSONArray(json);
JSONArray cities = data.getJSONArray();
// looping through All cities
for (int i = 0; i < cities.length(); i++) {
JSONObject e = cities.getJSONObject(i);
String ci_name = e.getString("ct_name");
String ci_web_id = e.getString("ct_id");
db.addCity(ci_name, ci_web_id);
db.closeDatabase();
}
JSONArray districts = data.getJSONArray(1);
// looping through All districts
for (int i = 0; i < districts.length(); i++) {
JSONObject e = districts.getJSONObject(i);
String di_name = e.getString("ar_name");
String di_web_id = e.getString("ar_id");
db.addDistrict(di_name, di_web_id);
db.closeDatabase();
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
The return data is like that :
{"city":[
{"ct_id":"1432","ct_name":"\u062e\u0645\u064a\u0633 \u0645\u0634\u064a\u0637","ct_hide":"0","ct_ord":"0","ct_created":"0"},
{"ct_id":"1434","ct_name":"\u0639\u0633\u064a\u0631","ct_hide":"0","ct_ord":"0","ct_created":"0"},{"ct_id":"1435","ct_name":"\u0627\u0644\u0645\u0646\u0637\u0642\u0629 \u0627\u0644\u0634\u0631\u0642\u064a\u0629","ct_hide":"0","ct_ord":"0","ct_created":"0"}
], "area":[
{"ar_id":"1422","ar_name":"\u0627\u0644\u0645\u062f\u064a\u0646\u0629 \u0627\u0644\u0645\u0646\u0648\u0631\u0647","ar_hide":null,"ar_ord":null,"ar_created":null}, {"ar_id":"1433","ar_name":"\u0646\u062c\u0631\u0627\u0646","ar_hide":null,"ar_ord":null,"ar_created":null}]
}
Your json is a JSONObject not a JSONarray.
This
data = new JSONArray(json);
is wrong.
{ // json object node
"city": [ // json array city
{ // json object
"ct_id": "1432",
"ct_name": "خميس مشيط",
"ct_hide": "0",
"ct_ord": "0",
"ct_created": "0"
},
{
"ct_id": "1434",
"ct_name": "عسير",
"ct_hide": "0",
"ct_ord": "0",
"ct_created": "0"
},
{
"ct_id": "1435",
"ct_name": "المنطقة الشرقية",
"ct_hide": "0",
"ct_ord": "0",
"ct_created": "0"
}
],
"area": [ // json array area
{
"ar_id": "1422",
"ar_name": "المدينة المنوره",
"ar_hide": null,
"ar_ord": null,
"ar_created": null
},
{
"ar_id": "1433",
"ar_name": "نجران",
"ar_hide": null,
"ar_ord": null,
"ar_created": null
}
]
}
To parse
JSONObject jb = new JSONObject(json);
JSONArray city = jb.getJSONArray("city");
for(int i=0;i<city.length();i++)
{
JSONObject jb1 = city.getJSONObject(i);
String id = jb1.getString("ct_id");
String name = jb1.getString("ct_name");
String hide = jb1.getString("ct_hide");
String ord = jb1.getString("ct_ord");
String created = jb1.getString("ct_ord");
Log.i("city id is",id);
}
JSONArray area = jb.getJSONArray("area");
for(int i=0;i<area.length();i++)
{
JSONObject jb1 = area.getJSONObject(i);
String id = jb1.getString("ar_id");
String name = jb1.getString("ar_name");
String hide = jb1.getString("ar_hide");
String ord = jb1.getString("ar_ord");
String created = jb1.getString("ar_ord");
Log.i("Area id is",id);
}
You could also consider using gson to parse json to java objects

I don't see any request to remote url. How do you get data from your server?
Generally, it looks like this:
public void execute() {
final AndroidHttpClient client = AndroidHttpClient.newInstance("TAG");
try {
HttpUriRequest request = getRequest();
HttpResponse response = client.execute(request);
final int code = response.getStatusLine().getStatusCode();
Log.d("TAG", "Server returns " + code);
if (code == HttpStatus.SC_OK) {
String json = EntityUtils.toString(response.getEntity());
handleResult(json);
}
} catch (IOException e) {
Log.e("TAG", "Failed to execute response", e);
}
}
private void handleResult(String json) {
try {
JSONObject jObject = new JSONObject(json);//your response is not an array
JSONArray content = jObject.getJSONArray("city")
final int count = content.length();
for (int i = 0; i < count; i++) {
JSONObject city = content.getJSONObject(i);
Log.d("TAG", city.getString("ct_id"));
}
} catch (JSONException e) {
Log.e("TAG", "Failed to obtain json", e);
}
}
How can i extract the json below and save it in an arraylist.
{
"trains": {
"train": [
{
"#id": 1000000103,
"#version": 1,
"#status": "active",
"#name": "dffffff",

}
}
]
}
}
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.

I have a JSON result in the following format which JSON Lint shows this as a Valid Response.
My question is: how do I accesss the content of "reportId0" value "164", "reportId1" value 157,reportId2 value 165, etc are all dynamic values?
My sample code for accessing value of properties.How to get Value reportid And add allvalue in Arraylist?
"properties": {
"link": "",
"approvalsReportCount": 3,
"reportName0": "srcapprovals",
"reportId0": 164,
"reportName1": "Approvals",
"reportId1": 157,
"requests_report_id": "163",
"requests_report_name": "EG approvals",
"reportName2": "fulfillment",
"reportId2": 165
}
This is the best way i found it to get ReportId value.
Below is My code
JSONObject jObj = new JSONObject(result);
JSONObject jsonResultArray = jObj.getJSONObject("results");
JSONObject pro_object = jsonResultArray.getJSONObject("properties");
Iterator keys = pro_object.keys();
while(keys.hasNext()) {
String currentDynamicKey = (String)keys.next();
String value = pro_object.getString(currentDynamicKey);
String upToEightCharacters = currentDynamicKey.substring(0, Math.min(currentDynamicKey.length(), 8));
if(upToEightCharacters.startsWith("reportId"))
{
Log.v("key"," new report ID key " + currentDynamicKey);
Log.v("key"," new report ID key " + pro_object.getString(currentDynamicKey) );
}
}
you can use this
public ArrayList<String> getReportIds() {
boolean isContinue = true;
JSONObject json;
String tag = "reportId";
int i = 0;
ArrayList<String> repIdList = new ArrayList<String>();
JSONObject prop = null;
try {
json = new JSONObject("<your json string>");
prop = json.getJSONObject("properties");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
while (isContinue) {
String repId = "";
try {
repId = prop.getString(tag + i);
repIdList.add(repId);
i++;
} catch (JSONException e) {
isContinue = false;
e.printStackTrace();
}
}
return repIdList;
}
You can Try This!!
try {
JSONObject jObj = new JSONObject(result);
JSONObject jsonResultArray = jObj.getJSONObject("results");
Log.v("log_tag","json result Array : "+ jsonResultArray);
JSONObject pro_object = jsonResultArray.getJSONObject("properties");
Iterator keys = pro_object.keys();
while(keys.hasNext()) {
// loop to get the dynamic key
String currentDynamicKey = (String)keys.next();
String value = pro_object.getString(currentDynamicKey);
approvaldto_Key = new All_Approval_Key_dto();
String upToEightCharacters = currentDynamicKey.substring(0, Math.min(currentDynamicKey.length(), 8));
if(upToEightCharacters.startsWith("reportId"))
{
approvaldto_Key.requestId = pro_object.getString(currentDynamicKey);
fetchrecursUserData.add(approvaldto_Key);
}
}
}
catch (JSONException e) {
e.printStackTrace();
}
return fetchrecursUserData;
}
You can try below code
String serial= jsonObject.getJSONObject("response").getString("serialNumber");
or
JSONObject json;
try {
json = new JSONObject(buffer.toString());
String accessToken = json.getString("access_token");
return accessToken;
} catch (JSONException e) {
Log.e("Podcast", "There was an error", e);
}
