This is my code :
JSONObject arrayobject = new JSONObject(preferences.getString("test", ""));
String responseobject = arrayobject.getString("array"+index);
JSONObject object = new JSONObject(responseobject);
This is the arrayobject :
{"array0":"{"myarray":[{"innerkey":"innervalue"}],"key":"value"}"}
This is the responseobject (it is a string) :
{
"myarray": [
{
"innerkey": "innervalue"
}
],
"key": "value"
}
Why is object always set to NULL ??
Please help me out!
You need to take two json object for fetching json array and jsonobject from your response.
Try Below code
JSONObject jsonObject = new JSONObject(preferences.getString("test", ""));
JSONObject jsonObject1 = new JSONObject(preferences.getString("test", ""));
JSONObject jbj;
JSONArray jsonArray = new JSONArray(jsonObject .getString("myarray"));
for (int i = 0; i < jsonArray.length(); i++)
{
jbj= jsonArray.getJSONObject(i);
String innerkey= jbj.getString("innerkey");
}
String key = jsonObject1 .getString("key");
Hope it helps you.

how to get this json Structure
String jsonString;
JSONArray jsonArray= new JSONArray(jsonString;);
for(int i=0;i<jsonArray.length();i++)
{
JSONObject jsono= (JSONObject) jsonArray.get(i);
JSONArray ServiceArray= (JSONArray ) jsono.get(i);
for(int j=0;j<ServiceArray.length();j++)
{
String id=jsonobject.getString("id");
String service_name=jsonobject.getString("service_name");
String act_stat=jsonobject.getString("act_stat");
}
}

First of all get JSONObject from JSONArray and then get particular field from that JSONObject like below :
JSONArray array;
for(int n = 0; n < array.length(); n++)
{
JSONObject object = array.getJSONObject(n);
String id = object .getString("id");
String service_name = object .getString("service_name");
String act_stat = object .getString("act_stat");
}
First of all get JSONObject from JSONArray and then get particular field from that JSONObject like below :
JSONObject jsonObj = new JSONObject(jsonStr);
SONArray jArray = jsonObj.getJSONArray("serviceData");
for (int i = 0; i < jArray.length(); i++) {
JSONObject jObject = jArray.getJSONObject(i);
String id = jObject.getString("id");
String service_name = jObject.getString("service_name");
String act_stat = jObject.getString("act_stat");
}
I have json data as mentioned below.
{
"data":[
{
"Products":{
"id":"86",
"pname":"mi4",
"pcat":"9",
"subcat":"8",
"seccat":"0",
"oproduct":"1",
"pdetails":"Good phone",
"pprice":"10000",
"pdiscount":"10",
"qty":"1",
"qtytype":"GM",
"dcharge":"40",
"pimage":null,
"sname":"Easydeal",
"sid":"1100",
"size":"",
"pincode":""
}
}
]
}
I can identify array as getJSONArray("datas"). But I want to get pname and sname values.
Just reach the object
JSONObject resp=new JSONObject("response");
JSONArray data=resp.getJSONArray("data");
now if you want to get object at a particular index(say '0')
JSONObject objAt0=data.getJSONObject(0);
JSONObject products=objAt0.getJSONObject("products");
String pName=products.getString("pname");
you can similarly traverse the array
for(int i=0;i<data.lenght();i++){
JSONObject objAtI=data.getJSONObject(i);
JSONObject products=objAtI.getJSONObject("products");
String pName=products.getString("pname");
}
To get the to the key "Products" you should do:
JSONObject productsObject = YOUROBJECTNAME.getJSONArray("data").getJSONObject(0).getJSONObject("Products");
Then to get the values in productsObject you should do:
productsObject.getString("id");
productsObject.getString("pdetails");
And so on.
Try out the following code:
JSONObject object = new JSONObject(result);
JSONArray array = object.getJSONArray("data");
JSONObject object1 = array.getJSONObject(0);
JSONObject products = object1.getJSONObject("Products");
int id = object1.getInt("id");
String pname = object1.getString("pname");
This is how you get pname and sname:
JSONObject jsonObject = new JSONObject();
JSONArray jsonArray;
try {
jsonArray = jsonObject.getJSONArray("data");
for(int counter = 0; counter <jsonArray.length(); counter++){
JSONObject jsonObject1 = jsonArray.getJSONObject(counter);
JSONObject products = jsonObject1.getJSONObject("Products");
String pname = products.getString("pname");
String sname = products.getString("sname");
}
} catch (JSONException e) {
e.printStackTrace();
}
PS: Poor JSON structure :)
I want parse details of "name" and "id" here is my json and android code
{
"main": {
"details": [
{
"name": "name1",
"id": "id1"
},
{
"name": "name2",
"id": "id2"
}
]
}
}
and my code is:
try {
JSONObject jsono = new JSONObject(url);
SONArray jarray = jsono.getJSONArray("main");
for (int i = 0; i < jarray.length(); i++) {
JSONObject object = jarray.getJSONObject(i);
Actors actor = new Actors();
actor.setLink(object.getString("name"));
actor.setImage(object.getString("id"));
actorsList.add(actor);
}
return true;
}
I want out put "id" and "name"
try Like this:
JSONObject totalObject = new JSONObject(result);
JSONObject mainObject = totalObject.getJSONObject("main");
JSONArray jsonArray = mainObject.getJSONArray("details");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject object = (JSONObject) jsonArray.get(i);
Actors actor = new Actors();
actor.setLink(object.getString("name"));
actor.setImage(object.getString("id"));
actorsList.add(actor);
}
Follow by this way:
try {
JSONObject jsono = new JSONObject(url);
SONArray jarray = jsono.getJSONArray("main");
for (int i = 0; i < jarray.length(); i++) {
JSONObject object = jarray.getJSONObject(i);
String name = object.getString("name");
String id = object.getString("id");
}
return true;
}
main is JSONObject, details is JSONArray, so the correct code to declare jarray is the following:
JSONArray jarray = jsono.getJSONObject("main").getJSONArray("details");
You have a JSONObject "main", containing a JSONOArray "details". This means you have to call getJSONObject("main").getJSONArray("details");
If you are going to such parsing multiple times, I'd recommend you to take a look at Gson - it is much easier with it. You have to set a SerializableName attribute to the link and image fields of the Actor class and Gson will take care to map them with the values from the json.
I'm trying to get data once user logged in successfully but I never get any of results, what I am doing is next:
// response is my request to server
JSONObject obj = new JSONObject(response);
Log.d("RESPONSE",obj.toString());
so in log I do see values, like:
04-19 11:28:16.729: D/RESPONSE(3162): {"data":[{"loses":3,"username":"benedict","level":1,"strength":15,"experience":null,"gold":10,"password":"benedict","intelligence":5,"agility":10,"wins":5}],"status":true}
but once I try to read username for example like this:
String username = obj.getString("username");
The code above ^ gives me nothing in my string..
Any help how I can retrieve data from JSONObject? Thanks!
That is because the username is present in the data object, which happens to be an JSONArray. Get the data array from the response object, traverse through each JSONObject in the array, and from each object, extract your username.
Something like this:-
JSONObject obj = new JSONObject(response);
JSONArray data = obj.getJSONArray("data");
for(int i=0;i<data.length();i++){
JSONObject eachData = data.getJSONObject(i);
System.out.println("Username= "+ eachData.getString("username"));
}
your field username is in array data. To access into this try :
JSONObject obj = new JSONObject(response);
JSONArray array = obj.getJSONArray("data");
for(int i = 0; i < array.length(); ++i){
JSONObject data = array.getJSONObject(i);
String username = data.getString("username");
}
You need to first get JSONArray which is data :
JSONArray data = null;
data = json.getJSONArray("data");
for(int i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
String username = c.getString("username");
}
You can get idea about parsing JSON from HERE
Try this...
try {
JSONObject object = new JSONObject(response);
JSONArray Jarray = object.getJSONArray("data");
for (int i = 0; i < Jarray.length(); i++) {
JSONObject Jasonobject = Jarray.getJSONObject(i);
String loose= Jasonobject.getString("loses");
String username=Jasonobject.getString("username");
.......
........
}
} catch (JSONException e) {
Log.e("log_txt", "Error parsing data " + e.toString());
}
I want to create a Json structure which is actually a JsonArray inside a JsonObject.
The sample structure is:
1.
{
“req”: [
{
“ctrlId”:”txt1”
},
{
“ctrlId”:”txt2”
}
]
}
2.
{
“req”: [
{
“ctrlId”:”txt1”,
“val” : “val1”
},
{
“ctrlId”:”txt2”,
“val” : “val2”
}
]
}
But i am not able to get it..Any help is appreciated..
JSONObject obj = new JSONObject();
JSONArray req = new JSONArray();
JSONObject reqObj = new JSONObject()
reqObj.put( "ctrlId", "txt1" );
req.put( reqObj );
reqObj = new JSONObject();
reqObj.put( "ctrlId", "txt2" );
req.put( reqObj );
obj.put( "req", req );
The final object is obj
I have this array
{
"result": "success",
"countryCodeList":
[
{"countryCode":"00","countryName":"World Wide"},
{"countryCode":"kr","countryName":"Korea"}
]
}
Here below I am fetching country details, so I have used valArray.getJSONArray(1)
You can use valArray.getJSONArray(0)
JSONObject json = new JSONObject(jsonstring);
JSONArray nameArray = json.names();
JSONArray valArray = json.toJSONArray(nameArray);
JSONArray valArray1 = valArray.getJSONArray(1);
valArray1.toString().replace("[", "");
valArray1.toString().replace("]", "");
int len = valArray1.length();
for (int i = 0; i < valArray1.length(); i++) {
Country country = new Country();
JSONObject arr = valArray1.getJSONObject(i);
country.setCountryCode(arr.getString("countryCode"));
country.setCountryName(arr.getString("countryName"));
arrCountries.add(country);
}
you can use GSON for doing this parsing. it will make your life simple.
