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);
}
}
}

How can i read all the keys in the json and how can count all the data in the Jsonarray
My code-->
String members = s;
/* s contain {"721xxxxxxx":true,"722xxxxxxx":true,"723xxxxxxx":true} */
JSONArray jsonChildArr = new JSONArray(members);
Log.e("Error","Data in jsonArray--->"+jsonChildArr.length());
Simple Way to Read JSON Object
JSONObject jsonObject = new JSONObject(members);
Log.i("Data","Data in jsonObject--->"+jsonObject.getBoolean("721xxxxxxx"));
Do Like this.
try {
String members = s;
/* s contain {"721xxxxxxx":true,"722xxxxxxx":true,"723xxxxxxx":true} */
JSONObject obj = new JSONObject(members);
JSONArray array = obj.names();
Log.d("ItemCount",array.length()+"");
for(int i=0;i<array.length();i++){
Log.d("Item",array.getString(i)+":"+ obj.getBoolean(array.getString(i));
}
} catch (JSONException e) {
e.printStackTrace();
}
Try this,
JSONObject jsonObject = new JSONObject(result);
boolean data = jsonObject .getBoolean("721xxxxxxx");
Log.d("Data","data:"+data );
try this:
String jsonStr = "{"721xxxxxxx":true,"722xxxxxxx":true,"723xxxxxxx":true}";
JSONObject itemJsonObj = new JSONObject(jsonStr );
HashMap<String,Boolean> result = new HashMap<>();
while(itemJsonObj.keys().hasNext()){
//parse json and save as key-value.
result.put(itemJsonObj.keys().next()+"",itemJsonObj.get(itemJsonObj.keys().next());
// result.size() is like array's size.
}
I wrote a library for parsing and generating JSON in Android http://github.com/amirdew/JSON
for your sample:
JSON jsonData = new JSON(jsonString);
int count = jsonData.count();
I want to get the id ^& content value in http://rest-service.guides.spring.io/greeting
What i tried is,
try {
JSONObject jsonObj = new JSONObject(parsingUrl);
// If you have array
JSONArray resultArray = jsonObj.getJSONArray("id"); // Here you will get the Array
// Iterate the loop
for (int i = 0; i < resultArray.length(); i++) {
// get value with the NODE key
JSONObject obj = resultArray.getJSONObject(i);
String name = obj.getString("content");
}
// If you have object
//String result1 = jsonObj.getString("result");
} catch (Exception e) {
e.printStackTrace();
}
Thanks
The url that your mentioned dont have json arrays, parsing will be like
try {
JSONObject jsonObj = new JSONObject(resultfromUrl);
int id = jsonObj.getInt("id");
String name = jsonObj.getString("content");
} catch (JSONException e) {
e.printStackTrace();
}
Currently, I'm having a minor trouble trying to get the string data from the jsonArray, however, I'm unable to get the value . I've got the data in the json object Example:
{
"lot":[
{
"id":"271",
"lot_date":"2015-05-25"
}
],
"numb3":[
{
"id":"675",
"lot_date":"2015-05-25"
}
],
"num4":[
{
"id":"676",
"lot_date":"2015-05-25"
}
],
"result":"OK"
}
The data above is stored in the JsonObject jsonobj. And what I want to do is to check if the JSON array JSONArray lot6 = jsonobj.optJSONArray("lot6"); contains the values or not , and if it's not null get the string data. However, even the data contains in the lot6 array, the result is null.
JSONArray lot6 = jsonobject.optJSONArray("lot6");
Log.d("LOT6",lot6+"");
if (lot6 != null) {
jsonarry2 = jsonobject.getJSONArray("lot6");
//3.if not null get the string data from the
for (int i = 0; i < jsonarry2.length(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
jsonobject = jsonarry2.getJSONObject(i);
ListData worldpop = new ListData();
worldpop.set_date(jsonobject.optString("lot_date"));
worldpop.set__id(jsonobject.optString("id"));
world.add(worldpop);
}
//5. test this part of the variable
String lotdate = world.get(0).get_date();
String lotid = world.get(0).get__id();
Hi please check Not lot6 its lot. please folloe below formate to get out out.
String s="{\"lot\":[{\"id\":\"271\",\"lot_date\":\"2015-05-25\"}],\"numb3\":[{\"id\":\"675\",\"lot_date\":\"2015-05-25\"}],\"num4\":[{\"id\":\"676\",\"lot_date\":\"2015-05-25\"}],\"result\":\"OK\"} ";
try{
JSONParser parser = new JSONParser();
JSONObject json = (JSONObject) parser.parse(s);
String arr[]={"lot","numb3","num4"};
for(int i=0;i<json.size()-1;i++){
JSONArray ja=(JSONArray)json.get(arr[i]);
for(int j=0;j<ja.size();j++){
JSONObject jo1=(JSONObject) ja.get(j);
System.out.println("lot_date: "+jo1.get("lot_date")+" Id "+jo1.get("id"));
}
// System.out.println(ja);
}
System.out.println(json.get("result"));
}catch (Exception e) {
System.out.println(e);

l get string with answer from server. l want to do it JSONObject.
l do
JSONObject jsonObj = new JSONObject(json);
in json has
"{"sentences":[{"trans":"R\u0455R\u0491ReR\u0405","orig":"�\u0455�\u0491��\u0405","translit":"","src_translit":"R\u1E91Rg\u0300RoR\u1E90"}],"src":"ru","server_time":1}"
but jsonObj has
"{"sentences":[{"src_translit":"RẑRg̀RoRẐ","orig":"�ѕ�ґ��Ѕ","trans":"RѕRґReRЅ","translit":""}],"server_time":1,"src":"ru"}"
so how l can get value from "trans":"RѕRґReRЅ"?
PS RѕRґReRЅ it's "own" in normal charset
If you already have the jsonObj you just have to do:
try {
// Getting Array of Sentences
sentences = json.getJSONArray("sentences");
// looping through All Contacts
for(int i = 0; i < sentences.length(); i++){
JSONObject c = sentences.getJSONObject(i);
// get the value from trans
String trans = c.getString("trans");
//now you should save this string in an array
}
} catch (JSONException e) {
e.printStackTrace();
}
try this
JSONObject jsonObj = new JSONObject(json);
JSONArray sentences = jsonObj.getJSONArray("sentences");
for(int i=0;i<sentences.length();i++){
JSONObject number = sentences.getJSONObject(i);
String transValue = number.getString("trans");
}
First you have to remove single quote form starting and from ending of your JSON string (json), by this your JSON will be a valid json for this you have to do like :
json= json.substring(1, json.length()-1);
After that you do like this :
JSONObject oJsonObject = new JSONObject(json);
JSONArray oJsonArray = oJsonObject.getJSONArray("sentences");
for(int i=0; i<oJsonArray.length(); i++)
{
JSONObject oJsonObject1 = oJsonArray.getJSONObject(i);
String transValue = oJsonObject1 .getString("trans");
}
I am trying to get a list of available numbers from the following json object, using the class from org.json
{
"response":true,
"state":1,
"data":
{
"CALLERID":"81101099",
"numbers":
[
"21344111","21772917",
"28511113","29274472",
"29843999","29845591",
"30870001","30870089",
"30870090","30870091"
]
}
}
My first steps were, after receiving the json object from the web service:
jsonObj = new JSONObject(response);
jsonData = jsonObj.optJSONObject("data");
Now, how do I save the string array of numbers?
use:
jsonObj = new JSONObject(response);
jsonData = jsonObj.optJSONObject("data");
JSONArray arrJson = jsonData.getJSONArray("numbers");
String[] arr = new String[arrJson.length()];
for(int i = 0; i < arrJson.length(); i++)
arr[i] = arrJson.getString(i);
you need to use JSONArray to pull data in an array
JSONObject jObj= new JSONObject(your_json_response);
JSONArray array = jObj.getJSONArray("data");
Assuming that you are trying to get it in a javascript block, Try something like this
var arrNumber = jsonData.numbers;
My code is for getting "data":
public void jsonParserArray(String json) {
String [] resultsNumbers = new String[100];
try {
JSONObject jsonObjectGetData = new JSONObject(json);
JSONObject jsonObjectGetNumbers = jsonObjectGetData.optJSONObject("results");
JSONArray jsonArray = jsonObjectGetNumbers.getJSONArray("numbers");
for (int i = 0; i < jsonArray.length(); i++) {
resultsNumbers[i] = jsonArray.getString(i);
}
} catch (JSONException e) {
e.printStackTrace();
Log.e(LOG_TAG, e.toString());
}
}
