I want to get value from json.But I can't get value.
I want to get 26/08/15 value.
json format:
{"Timestamp":["26/08/15"]}
My code :
JSONArray timestamp = jsonObj .getJSONArray("Timestamp");
JSONObject timecatObj = (JSONObject) timestamp.get(0);
Iterator temp = timecatObj.keys();
serverdate = temp.toString();
JSONObject ob = new JSONObject("{"Timestamp":["26/08/15"]}")
JSONArray arr = ob.optJSONArray("Timestamp",null);
String date = arr.optString(0);
{"Timestamp":["26/08/15"]}, the value of "Timestamp" is a JSONArray, but the element of the JSONArray is String not JSONObject.
So, the code should be :
JSONArray timestamp = jsonObj.getJSONArray("Timestamp");
String serverdate = timestamp.optString(0);

I'm a android beginner and I'm doing to access a JSON file in and it has an error. I have a problem in parsing this
JSONObject jsonObject = new JSONObject(jsonStr);
JSONArray accounts = jsonObject.getJSONArray("account_data");
for(int i=0;i < accounts.length();i++){
JSONObject a = accounts.getJSONObject(i);
sin = a.getString("sin");
account_name = a.getString("account_name");
address = a.getString("address");
status = a.getString("status");
due_date = a.getString("due_date");
total_amount = a.getDouble("total_amount");
sin_lbl.setText(a.getString("account_name"));
}
here is the JSON File
{"account_data":{
"sin":"200111-102 ",
"account_name":"LUMABAN, CRISTOM ",
"address":"352 MABINI ST.,, SABANG, Baliwag ",
"status":"A ",
"due_date":"2019-04-23",
"total_amount":"491.00"
},"code":1101,"message":"Account Info Retrieved"}
I have an error in putting it in array.
Instead of using JSONArray , try to use JSONObject.
String[] array = {json.get("sin"), json.get("account_name"), json.get("address"), json.get("status"), json.get("due_date"), json.get("total_amount") }
{"account_data":{"sin":"200111-102 ","account_name":"LUMABAN, CRISTOM ","address":"352 MABINI ST.,, SABANG, Baliwag ","status":"A ","due_date":"2019-04-23","total_amount":"491.00"},"code":1101,"message":"Account Info Retrieved"}
Actually, it's a json object, not array. So that you can not convert json object to json array
Difference between Json Array and Json Object:
A JSONArray is an ordered sequence of values. A JSONObject is an unordered collection of name/value pairs.
JSONArray: Its external text form is a string wrapped in square brackets with commas separating the values.
JSONObject: Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names.
Please use this json parshing
try {
JSONObject jsonObject = new JSONObject(jsonStr);
JSONObject accounts = jsonObject.getJSONObject("account_data");
sin = accounts.getString("sin");
account_name = accounts.getString("account_name");
address = accounts.getString("address");
status = accounts.getString("status");
due_date = accounts.getString("due_date");
total_amount = accounts.getDouble("total_amount");
sin_lbl.setText(a.getString("account_name"));
} catch (Exception e) {
}
if you asked about iterating on json object you could try this one
JSONObject jObject = new JSONObject(jsonStr);
JSONObject menu = jObject.getJSONObject("account_data");
Map<String,String> map = new HashMap<String,String>();
Iterator iter = menu.keys();
while(iter.hasNext()){
String key = (String)iter.next();
String value = menu.getString(key);
map.put(key,value);
}
so now you have your data into as pair of key and value
if you have a json array of this response you could do as following
JSONObject root = new JSONObject("your root");
JSONArray resultArray = root.getJSONArray("your array key");
for (int i = 0; i < resultArray.length(); i++) {
// here to get json object one by one and access every item into it
JSONObject resultObject = resultArray.getJSONObject(i);
posterPath = resultObject.getString("key");
title = resultObject.getString("key");
releaseDate = resultObject.getString("key");
description = resultObject.getString("key");
voteAverage = resultObject.getDouble("key");
}
My below android code is throwing
org.json.JSONException: Value
{"ID":1,"DisplayName":"Manish","UserName":"manish.parab#hotmail.com"}
at AuthenticateUserResult of type org.json.JSONObject cannot be
converted to JSONArray
Code:
String response = Common.ExecuteHttpRequest(Url);
JSONObject jsonObject = new JSONObject(response);
JSONArray jArray = jsonObject.getJSONArray("AuthenticateUserResult");
response is string from WCF method.
{"AuthenticateUserResult":{"DisplayName":"Manish","ID":1,"UserName":"manish.parab#hotmail.com"}}
The value of AuthenticateUserResult is a JSON Object (it's enclosed in {}).
Change that line to this
JSONObject jArray = jsonObject.getJSONObject("AuthenticateUserResult");
Then you can get your data as follows :
String displayName = jArray.getString("DisplayName");
// Etc...
There are three workarounds to solve this problem.
1.Use JsonObject. Your WCF server just give it in JsonObject.
String response = Common.ExecuteHttpRequest(Url);
JSONObject jsonObject = new JSONObject(response).getJSONObject("AuthenticateUserResult");
2.Use json array as a container
String response = Common.ExecuteHttpRequest(Url);
JSONObject jsonObject = new JSONObject(response);
JSONArray jArray = new JSONArray().put(jsonObject.getJSONObject("AuthenticateUserResult"));
3.Edit server to provide AuthenticationUserResult into json array. The right format would be as below.
{"AuthenticateUserResult":[{"DisplayName":"Manish","ID":1,"UserName":"manish.parab#hotmail.com"}]}
The exception is right, because "AuthenticateUserResult" value is declared as an element ({}) and not as an array ({}).
To fix this, use getJSONObject method to get the value of "AuthenticateUserResult", like this:
String response = Common.ExecuteHttpRequest(Url);
JSONObject jsonObject = new JSONObject(response);
JSONObject result = jsonObject.getJSONObject("AuthenticateUserResult");
After that, you can retrieve a child element, like:
String mUserName = result.getString("UserName");
I'm trying to parse the following JSON string
String _message = "GetXTRONResult: \"[{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}]\"";
JSONObject jsonObj = new JSONObject(_message);
//Try to convert to array
JSONArray array = jsonObj.getJSONArray("GetXTRONResult"); //FAILS !
What is the best way to parse the above please?
UPDATE:
This is what the value is during debugging:
{"GetXTRONResult":"[{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}]"}
org.json.JSONException: Value .... at GetXTRONResultof type java.lang.String cannot be converted to JSONArray
SOLUTION THAT WORKED FOR ME:
I had to use the iterator as follows:
ArrayList list = new ArrayList();
JSONObject jsonObj = new JSONObject(_message);
Iterator<?> keys = jsonObj.keys();
if (keys.hasNext()) {
JSONArray array = new JSONArray((String) jsonObj.get((String) keys.next()));
for (int i = 0; i < array.length(); ++i) {
list.add(array.getJSONObject(i).getString("xtron").toString());
}
You have some errors in your json string, like "[.
You can't use quotes that wrap your list.
This one should work:
String _message = "{\"GetXTRONResult\": [{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}]}";
JSONObject jsonObj = new JSONObject(_message);
//Try to convert to array
JSONArray array = jsonObj.getJSONArray("GetXTRONResult");
System.out.println(array);
Output: [{"xtron":"Acub1"},{"xtron":"Acub2"},{"xtron":"Acub3A"}]
To avoid your confusion when making JSON in java/android
you could use single quote (') instead of double quote (") for JSON inside Java Code
For example:
from
"{\"xtron\":\"Acub1\"},{\"xtron\":\"Acub2\"},{\"xtron\":\"Acub3A\"}"
to be something like this
"{'xtron':'Acub1'},{'xtron':'Acub2'},{'xtron':'Acub3A'}"
I think this is what you're looking for:
JSONObject rootObj = new JSONObject(jsonString);
String theArrayJSON = rootObj.getJSONArray("GetXTRONResult");
JSONObject theArray = new JSONObject(theArrayJSON);
I have below string. i want to get jsonarray from this string keyword like id, title and so on.
Json_obj = new JSONObject(result);
vid = Json_obj.getJSONArray("id");
//vcatid= Json_obj.getJSONArray("title");
vtitle= Json_obj.getJSONArray("title");
vdesc= Json_obj.getJSONArray("content");
//vimgurl= Json_obj.getJSONArray("vimgurl");
vidlike= Json_obj.getJSONArray("likes");
vidview= Json_obj.getJSONArray("views");
//vidfblike= Json_obj.getJSONArray("vidfblike");
//vidtwlike= Json_obj.getJSONArray("vidtwlike");
storagepath= Json_obj.getJSONArray("url");
Log.i("json_Video_id vid.length() ",
"%%%%%%%%%%%%%%%%%%%%%% "
+ vid.length());

This is how you parse JSON Array
JsonElement json = new JsonParser().parse(response);
JsonArray array = json.getAsJsonArray();
Iterator iterator = array.iterator();
List<CustomClass> obj_list = new ArrayList<CustomClass>();
while (iterator.hasNext()) {
JsonElement json2 = (JsonElement) iterator.next();
Gson gson = new Gson();
CustomClass obj = gson.fromJson(json2, CustomClass.class);
obj_list.add(obj);
}
Here, CustomClass will be a class with the properties you want. That means the properties you get in Array, e.g. id, title, content, likes, views, url.
Hope it helps.
The outmost container of your JSON data is an array and not an object (it start and ends with square brackets). Thus, you need to use the class JSONArray and then iterate over all elements of the array:
String jsonString = ...
JSONArray arr = new JSONArray(jsonString);
for (int i = 0; i < arr.length(); i++) {
JSONObject obj = arr.getJSONObject(i);
String id = obj.getString("id");
String title = obj.getString("title");
...
}
When I am trying to access the Content of this below JSON , I am getting the Exception.
This is My JSON Value:
{"listDev":{"description":"D4684","deviceID":"d2","uniqueID":"0014018682"}}
This is my code to get the Content in "listDev"
JSONObject object = ApplicationContext.getHttpService().readAsJson(content);
JSONArray array = object.getJSONArray("listDev");
So, what to do to get the Contents like decription, imei...
Thanks in advance.
listDev is a JSONObject not a JSONArray:
change
JSONArray array = object.getJSONArray("listDev");
to
JSONObject array = object.getJSONObject("listDev");
String json = {"listDev":{"description":"D4684","deviceID":"d2","uniqueID":"0014018682"}};
JSONObject object = new JSONObject(json);
JSONObject array = object.getJSONArray("listDev");
