Parsing json code to a string in android using volley

i need help to parse this json code to actual strings using android volley. this is the json code:[{"name":"Tayo","0":"Tayo","thread_name":"Welcome","1":"Welcome","post":"Hi there,","2":"Hi there,","post_time":"Sunday","3":"Sunday"},{"name":"Pete","0":"Pete","thread_name":"Welcome","1":"Welcome","post":"Hi,am pete","2":"Hi,am pete","post_time":"Monday","3":"Monday"}].
I have tried other helps but not working. Thanks!

Remember:
if the .json content starts with { is considered as a Json Object.
if the .json content starts with [ is considered as a Json Array.
so you hava a JsonArray then you can parse your content like this way:
//Obtain the JsonArray
JSONArray jsonArray = new JSONArray(myJsonContent);
// Get the JsonObjects inside JsonArray
for(int i=0;i<jsonArray.length();i++){
JSONObject jsonobject = jsonArray.getJSONObject(i);
}

// strData is the json data received.
JSONArray jsonArray = new JSONArray(strData);
for (int i=0; i<jsonArray.length();i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
String name = jsonObject.optString("name");
String zero = jsonObject.optString("0");
String thread_name = jsonObject.optString("thread_name");
String one = jsonObject.optString("1");
String post = jsonObject.optString("post");
String two = jsonObject.optString("2");
String post_time = jsonObject.optString("post_time");
String three = jsonObject.optString("3");
//Just an example
arrayName.add(jsonObject.optString("name"));
}
You can even use array to store data instead of the string.

I am not able to Parse the json file. It begins with array

The following JSON starts with an array type which I am having a lots of problem to Parse. Please help.
[{"type":"1","name":"ABC","start_date":"5","end_date":null,"time":"00:00:00","description":"abc","venue":"","v_id":"1","c1name":"","c1phno":"","c1email":"","c2name":"","c2phno":"","c2email":""}]
Please help me out if possible.

Are you trying to get the data as a JSONArray?
It would look like this:
String json = "your json data";
JSONArray jsonArray = new JSONArray(json);
JSONObject jsonObject = jsonArray.getJSONObject(0);
String type = jsonObject.getString("type");
String name = jsonObject.getString("name");
And so on...

How parse json object and json array together

i have two situation of Json output .
one is data that found and i have a json array and a json object like this:
{"data":"yes"}[{"id":"10","number":"7","text":"text7","desc":"text7_again","user_code":"0"},{"id":"11","number":"8","text":"text8","desc":"text8_again","user_code":"1"}]
other situation is that data not found :
{"data":"no"}
just one json object.
how parse this data in android client for support two situtaion?

First, you should validate your json in http://jsonlint.com/ if you test it you will look that is a wrong json. So, for make it right, in your server your response should look something like this:
{"data":"yes","response":[{"id":"10","number":"7","text":"text7","desc":"text7_again","user_code":"0"},{"id":"11","number":"8","text":"text8","desc":"text8_again","user_code":"1"}]}
And in that case, in android
JSONObject jsonObj = new JSONObject(response);
if (jsonObj.getString("data").compareTo("yes") == 0) {
JSONArray jsonArray = jsonObj.getJSONArray("response");
//To-Do another code
}
and that's all

Here is a possible case: (you need to fix your json format)
Success -
string resultJSON =
{"success":true,
"data":[
{"id":"10","number":"7","text":"text7","desc":"text7_again","user_code":"0"},
{"id":"11","number":"8","text":"text8","desc":"text8_again","user_code":"1"}]}
Failed -
string resultJSON =
{"success":false}
Then
JSONObject jsonRoot = new JSONObject(resultJSON);
bool isSuccess = jsonRoot.getBoolean("success");
if (isSuccess) {
// do the array parser
for(int i=0; i<jsonData.lenght;i++) {
JSONObject jsonObj = jsonData.getJSONObject(i);
String id = jsonObj.getString("id"); // get the value of id
String desc = jsonObj.getString("desc"); // and so on...
}
}

Simple Json parsing in android

I got the Json response. I am not able to get the values from the string.my string is
Json_response is
{"NameAllList":[{"Current":{"time":"2012-02-21T08:04:21","Name":"abcd"},
"Next":{"Name":"data1","StartTime":"2012-02-21T08:06:21"}},{"Current":{"time":"2012-02-21T08:14:21","Name":"defg"},
"Next":{"Name":"data2","StartTime":"2012-02-21T08:24:21"}},{"Current":{"time":"2012-02-21T08:28:21","Name":"ghij"},
"Next":{"Name":"data3","StartTime":"2012-02-21T08:34:21"}},{"Current":{"time":"2012-02-21T08:40:21","Name":"knmo"},
"Next":{"Name":"data4","StartTime":"2012-02-21T08:48:21"}}]}
and i tried this.
JSONObject jsonObj = new JSONObject(json_response);
JSONObject subObj = jsonObj.getJSONObject("Current");
String name_current =subObj.getString("Name");
but i am not able to get the value of "Name". what mistake i have done. provide the link to do the above parsing.

first of all, your JSON response is having NameAllList as a JSON Array of objects.
So you have to fetch JSON Array first, then you can fetch one-by-one object.
for example:
JSONObject jsonString = (new JSONObject(json_response_string));
JSONArray array = jsonString.getJSONArray("NameAllList");
for(int i=0; i<array.length(); i++)
{
// Retrieve Current object as such
JSONObject objCurrent = array.getJSONObject("Current");
// Retrieve Next object as such
JSONObject objNext = array.getJSONObject("Next");
}

You are not parsing json properly, so you are not able to fetch value of Name. Please note JSON Annotation [] represent JSONArray, and {} respresent JSONObject, so method to get current item's name is:
JSONObject jsonObj = new JSONObject(json_response_string);
JSONArray jsonArr=jsonObj.getJSONArray("NameAllList");
String Hora_name_current="";
for(int i=0;i<jsonArr.length();i++)
{
JSONObject obj=jsonArr.get(i);
try{
JSONObject subObj = obj.getJSONObject("Current");
Hora_name_current =subObj.getString("Name");
break;
}catch(JSONException ex)
{
}
}

looks like you're trying to use JSONObject when you should be using JSONArray for the second request. Try this:
JSONObject jsonString = (new JSONObject(json_response_string));
JSONArray array = jsonString.getJSONArray("NameAllList");
In your JSON return, "NameAllList is actually an array and needs to be handled as such. Once you set it to "array", you can then run a for loop and treat it like any other array in Java.
Let me know if that helps.

JSONObject jsonObj = new JSONObject(json_response_string);
JSONArray jsonArray = jsonObj.getJSONArrays("NameAllList");

Get JSONObject by ID from another JSONObject - Android

I have a little issue with parsing JSON String which I get from a web server. So my JSON looks something like this :
{
..........
"statistics":{
"660":{
"param_id":660,
"cat_id":2,
"param_title":"Number",
"param_value":"26",
"value_type":"singleline",
"elem_order":"1"}
,
"662":{
"param_id":662,
"cat_id":2,
"param_title":"Name",
"param_value":"Dani",
"value_type":"singleline",
"elem_order":"2"
}
// --||--
}
}
So I get a JSONObject statisics and I want to get JSONObjects from statistics, but the problem is that their name is different everytime.So I can't just do json.getJSONObject("660");. So any suggestions how can I do that?

You can do something like this :
if(jsonObj.has("statistics")){
Iterator<Object> keys = stats.keys();
while(keys.hasNext()){
String key = (String) keys.next();
JSONObject obj = new JSONObject();
obj = stats.getJSONObject(key);
// get JSON
}// end while
}//end if

use JSONObject.keys() to get key iterator, then getJsonObject( key) to get object.

Try below code-
JSONArray nameArray = statisics.names();
JSONArray valArray = statisics.toJSONArray(nameArray);
where names() method returns array of names and it is stored in nameArray and valArray contains array of values corresponding to valArray.
You can iterate using for loop over these array to get values.

use like this
JSONObject jsonOnb = json.getJSONObject("statistics") ;
JSONObject pagesObj = jsonOnb.getJSONObject(jsonOnb.names().getString(0));
Log.i("pageid", "pageid= " +pagesObj.get("param_id"));
Log.i("title", "title= " +pagesObj.get("cat_id"));
