There is no array name here, but I want to parse whole array (my JSON parser works fine if I'm using array name).
For parsing this type of JSON...
First store it in String..
and then do following process...
String str = "JSON STRING";
JSONArray jsonarray = new JSONArray(str);
for(int i=0; i<jsonarray.length(); i++){
JSONObject obj = jsonarray.getJSONObject(i);
String stDescription = obj.getString("stDescription");
String stCategory= obj.getString("stCategory");
//and other fields
System.out.println(stDescription);
System.out.println(stCategory);
}
This may help you...

I created an app that stream video from server, on server side (PHP) I use this code to pass the MySQL query result via JSON array contain a result of video title size and views.
$query="select * from video_tble ;";
$result=mysqli_query($con,$query);
$row=mysqli_fetch_all($result,MYSQLI_ASSOC);
$respones_result=array();
$response_result=$row;
echo json_encode(array("server_response_result"=>$response_result));
But I don't know how to retrieve a multidimensional array using JSON object.
JSONObject jsonObject1=new JSONObject(json);
JSONArray jsonArray1=jsonObject1.getJSONArray("server_response_result");
JSONObject JO1=jsonArray1.getJSONObject(0);
String [] title =...?
If it was a name value pair then I follow this strategy:
String title1=JO1.getString("title");
But I don't know what to do on multidimensional array.
Hi you need a for loop like this
for(int i;i<jsonArray1.size();i++){
JSONObject JO1=jsonArray1.getJSONObject(i);
String title1=JO1.getString("title");
}
To parse this json
{
"server_response_result": [{
"videoid": "1",
"videotitle": "Metro Shoes",
"userid": "7",
"category": "Fashion",
"dou": "0000-00-00",
"rate": "3",
"vstatus": "A",
"vcount": "321",
"location": "adstreamer\\uploads\\ramesh#gmail.com\\1.mp4"
}, {
"videoid": "2",
"videotitle": "Lijn the bus",
"userid": "7",
"category": "App",
"dou": "0000-00-00",
"rate": "4",
"vstatus": "A",
"vcount": "145",
"location": "adstreamer\\uploads\\ramesh#gmail.com\\2.mp4"
}]
}
You have to do following steps (saying you have the server response in jsonObject.
ArrayList<SomeModel> modelList = new ArrayList<>();
JSONArray serverResponseResult = jsonObject.getJsonArray("server_response_result");
for (int i = 0; i < serverResponseResult.length(); i++) {
JSONObject result = serverResponseResult.get(i);
String videoId = result.getString("videoid");
String videoTitle = result.getString("videotitle");
...
// instead of using String, set the values in the model class
modelList.add(/* model */);
}
In my application I'm trying to parse This structure type Json value. Did any of you guys face this issue? Any help would be greatly appreciated.
Main problem is double [[
[
[
{
"nid": "29",
"vid": "30",
"type": "oa_discussion_post",
"language": "und",
"title": "We want to hear from you.",
"uid": "1",
"status": "1",
"created": "1441316801",

}

Here is my approach:
JSONArray json = new JSONArray(jsonData);
for(int i=0;i<json.length();i++) {
HashMap<String, String> map = new HashMap<String, String>();
JSONObject e = json.getJSONObject(i);
String userType=e.getString("vid");
String topLine=e.getString("type");
}
Where is my error?
you have a nested array inside the top level array
for(int i=0;i<json.length();i++) {
JSONArray nestedJsonArray = json.optJSONArray(i);
if (nestedJsonArray != null) {
for(int j=0;j<nestedJsonArray.length();j++) {
// use j and nestedJsonArray to retrieve the JSONObect
HashMap<String, String> map = new HashMap<String, String>();
JSONObject e = nestedJsonArray.optJSONObject(i);
String userType=e.optString("vid");
String topLine=e.optString("type");
}
}
}
You have another JSONArraybut you use JSONObject. Just do
JSONArray firstArray = new JSONArray(jsonData);
JSONArray secondArray = firstArray.getJSONArray(0);
JSONObject jsonObject = secondArray.getJSONObject(0);
//Do want you want with your jsonObject
String userType = jsonObject .getString("vid");
String topLine = jsonObject .getString("type");
You have an object in an array in an array.
You have to select the first array in it instead of selecting the JSONObject directly. After selecting the second JSONArray, then select your JSONObject using getJSONObject(0);
i am doing now retrieving JSON array and assigning it to Android Array String but it failed.
My integer "success" already well. Please help, thank you very much.
My JSON information:
{
"details": [
{
"phone": "89898999",
"name": "Maria"
},
{
"phone": "98983555",
"name": "John"
},
{
"phone": "96969677",
"name": "Leo"
},
{
"phone": "97320099",
"name": "Helen"
},
{
"phone": "90063379",
"name": "Judy"
}
],
"success": 1
}
Android code:
String[] titleArray2;
String[] descriptionArray2;
int cs = 0;
.....
// Create a JSON object from the request response
JSONObject jsonObject = new JSONObject(result);
//Retrieve the data from the JSON object
cs = jsonObject.getInt("success")
JSONArray ja = jsonObject.getJSONArray("details");
for (int i = 0; i < ja.length(); i++)
{
JSONObject jo = (JSONObject) ja.get(i);
titleArray2[i] = jo.getString("phone");
descriptionArray2[i] = jo.getString("name");
}
Your code looks fine, Just try initializing your array
Try like this
JSONArray ja = jsonObject.getJSONArray("details");
titleArray2 =new String[ja.size];
descriptionArray2[i]=new String[ja.size];
and then your for loop.
Mark as right if it works for you. :)
I am trying to retrieve data using a URL using Json Parsing in Android.
I have done the following coding but I am not able to figure out how to parse the node which is present in the inner node items.
My json array and codes are posted as below. Please guide me step by step.

MainActivity.class
try {
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
items = jsonObj.getJSONArray(TAG_CONTACTS);
Log.i("json node",""+items);
// looping through All Contacts
for (int i = 0; i < items.length(); i++) {
JSONObject c = items.getJSONObject(i);
String id = c.getString("id");
//String name = c.getString(TAG_NAME);
Log.w("myid", id);
} catch (JSONException e) {
e.printStackTrace();
}
// fetch item array
JSONArray itemObjectArray = jsonStr.getJSONArray("items");
for (int i = 0; i < itemObjectArray.length(); i++) {
// fetch item object at i position
JSONObject itemObject = itemObjectArray.getJSONObject(i);
// fetch values from itemObject
String idValue = itemObject.getString("id");
String noteValue = itemObject.getString("Note");
// fetch the array
JSONArrayprefObject = itemObject.getJSONArray("preferncess");
// iterate throgh the array like
for (int i = 0; i < prefObject .length(); i++) {
JSONObject p = prefObject .getJSONObject(i);
}
}
preference is json array you can retrive it by c.getJSONArray("preferncess"); and then iterating. or in more generic you can Can you try something like following
if (c.get(key) instanceof String)
{
JSONObject Lawset = c.getString(key);
} else if (c.get(key) instanceof JSONObject)
{
JSONObject Lawset = c.getJSONObject(key);
//try to retrieve data from json object
}
else if (c.get(key) instanceof JSONArray)
{
JSONArray Lawset = c.getJSONArray(key);
//iterate to get data
}
I am sending request to the server and it gives me a response and giving data in JSON formats, now i want to fetch some specific value from that JSON format, so hot to do it.
{
"education": [
{
"school": {
"id": "2009305",
"name": "FG boys public high school Bannu Cantt "
},
"type": "High School"
},
{
"school": {
"id": "109989",
"name": "University of Engineering & Technology"
},
"type": "College"
}
],
"id": "xxxxxxx"
}
Now i need the school names from this xml,
Try this..
You response is in Json format not xml.
JSONObject json = new JSONObject(response);
JSONArray education = json.getJSONArray("education");
for(int i = 0; i < education.length(); i++){
JSONObject con_json = education.getJSONObject(i);
String school_type = con_json.getString("type");
JSONObject school_json = con_json.getJSONObject("school");
String school_name = school_json.getString("name");
}
It is not XML. it is completely in Json Standard format.
first build a JSONobject from your data:
JSONObject jsonObj = new JSONObject(result); //result = your Data String in fetched from server
then you cab retrieve what you want using its key. for example:
jsonObj.getString("id"); // it returns "xxxxxxx". as is in your data
