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 am pulling the data from the array I have assigned in the php file. I get an error pulling data from the Array output. The output is as follows:
org.json.JSONException: Value [{"program_dosya":"..."},{"program_dosya":"https:..."}, `{"program_dosya":"https:\/\/..."}] of type org.json.JSONArray cannot be converted to JSONObject`
I want to pull the "programfile" data assigned in array via android.
PHP
$results[] = Array("program_dosya" => $programdosya);
Android
try {
JSONObject jObj = new JSONObject(result);
JSONArray resultArray = jObj.getJSONArray("");
for(int i = 0; i < resultArray.length(); i++) {
JSONObject obj = resultArray.getJSONObject(i);
String name = obj.getString("programdosya");
}
} catch (JSONException e) {
e.printStackTrace();
}
As I understand you need to iterate over the json array -
// assuming you have string in this format, then all you have to do is
String result = "[{\"program_dosya\":\"...\"},{\"program_dosya\":\"https:...\"}]";
JSONArray array = new JSONArray(result);
for (int i=0; i<array.length(); i++) {
JSONObject js = array.getJSONObject(i);
String link = js.getString("program_dosya");
System.out.println(link);
}
I have know to parser JSON array in single array but how to pass multiple JSON array and set it value to require
{"scode":"200","all_menu":[{"app_menu_id":"67","app_menu_name":"Demograpics","all_sub_menu":[{"app_menu_id":"67","app_sub_menu_id":"47","app_sub_menu_name":"\u0a97\u0ac1\u0a9c\u0ab0\u0abe\u0aa4\u0ac0","app_sub_menu_image":"http:\/\/app.hindipublic.com\/app_allwhatsupstatus\/menu\/medium\/8451504072003.jpg"}],"sub_menu":"true"},{"app_menu_id":"68","app_menu_name":"Lyrics","all_sub_menu":[{"app_menu_id":"68","app_sub_menu_id":"48","app_sub_menu_name":"Music","app_sub_menu_image":"http:\/\/app.hindipublic.com\/app_allwhatsupstatus\/menu\/medium\/4681504072092.jpg"}],"sub_menu":"true"},{"app_menu_id":"69","app_menu_name":"Adult","all_sub_menu":[{"app_menu_id":"69","app_sub_menu_id":"49","app_sub_menu_name":"Double

Suppose "response" is your JSONResponse
JSONObject jsonObject = new JSONObject(response);// This is used to get jsonObject from response
String sCode=jsonObject.optString("scode"); // This is how you can parse string from jsonObject
JSONArray allmenuArray=jsonObject.optJSONArray("all_menu"); //This is how you can parse JsonArray from jsonObject
for(int i=0;i<allmenuArray.length();i++){
JSONObject objectJson=allmenuArray.optJSONObject(i);//This is how you can parse jsonObject from jsonArray
}
Like This you can parse all your jsonObject and jsonarray. Just follow these steps you can easily parse your full JSONResponse
Try this.
try {
JSONObject jsonObject = new JSONObject("JSONResponse");
String scode = jsonObject.optString("scode");
JSONArray allmenuArray = jsonObject.optJSONArray("all_menu");
for (int i = 0; i < allmenuArray.length(); i++) {
JSONObject objectJson = allmenuArray.optJSONObject(i);
boolean sub_menu = objectJson.getBoolean("sub_menu");
String app_menu_id = objectJson.getString("app_menu_id");
String app_menu_name = objectJson.getString("app_menu_name");
JSONArray all_sub_menu = objectJson.getJSONArray("all_sub_menu");
for (int j = 0; j < all_sub_menu.length(); j++) {
JSONObject data = allmenuArray.optJSONObject(j);
Log.e("app_menu_id", data.getString("app_menu_id"));
Log.e("app_sub_menu_id", data.getString("app_sub_menu_id"));
Log.e("app_sub_menu_name", data.getString("app_sub_menu_name"));
Log.e("app_sub_menu_image", data.getString("app_sub_menu_image"));
}
}
} catch (JSONException e) {
Log.e("ERROr", e.toString());
}
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 am working in Android and finding json from internet that looks like this:
JSONObject childObject=me.getJSONObject(pos);
String fisrtkey=childObject.getString("A");
JSONArray jsonArray=childObject.getJSONArray("c");
I want to find C21 that is in the A. See the json coming from request.
Can someone help me?
try {
JSONObject j=new JSONObject(data);
JSONArray c= null;
c = j.getJSONArray("This");
JSONObject item=c.getJSONObject(0);
JSONArray me=item.getJSONArray("me");
for(int pos=0;pos<me.length();pos++)
{
JSONObject childObject=me.getJSONObject(pos);
String fisrtkey=childObject.getString("A");
JSONArray jsonArray=childObject.getJSONArray("c");
}
} catch (JSONException e1) {
e1.printStackTrace();
}
//hope this will help you and also check json is invalid or not ,you missed
// bracket of jsonarray "me".
You have missed THIS json array while parsing. First get that and from that json object and then get ME json array. Something like this
JSONObject j = new JSONObject(data);
JSONArray c = j.getJSONArray("This");
JSONObject j1 = c.getJSONArray(0);
JSONArray d = j.getJSONArray("me");
for(int n = 0; n < c.length(); n++) {
JSONObject item = c.getJSONObject(n);
System.out.println(item.getString("A"));
}
Try this:
JSONObject j = new JSONObject(data);
JSONArray c = j.getJSONArray("me");
for(int n = 0; n < c.length(); n++) {
JSONObject person = (JSONObject) c.get(n );
String id = person.getString("A");
...
}
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");
}
