I got from server response by retrofit, that is actually JsonObject(using Gson):
{"a": "a and its content 1", "b": [{"b_1": "string: b_1", "b_2": 2222}]}
so that I get it like this:
JsonObject jsonObject = response.body();
And then I can log it:
Log.d(TAG, jsonObject.get("a")+"");
// log: "a and its content 1"
question:
How can I log only "string: b_1"? (from "b_1": "string: b_1")
As it is in array [], hard to get it for me.
Try this one work for me,
try {
JSONObject jsonObject = response.body();
JSONArray jsonArray = jsonObject.getJSONArray("b");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObj = jsonArray.getJSONObject(i);
String b_1 = jsonObj.getString("b_1");
int b_2 = jsonObj.getInt("b_2");
}
} catch (JSONException e) {
e.printStackTrace();
}
try this
try{
JsonObject jsonObject = response.body();
JSONArray a = jsonObject.getJSONArray("b")
for (int i = 0; i < a.length(); i++) {
Log.d("Type", a.getString(i));
}
}catch(Exception e){
}
Try like below
JSONObject jObj = response.body();
JSONArray jsonArray = jObj.getJSONArray("b");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
Log.d(TAG, jsonObject.getString("b_1")+"");
Log.d(TAG, jsonObject.getInt("b_2")+"");
}
try this
JSONObject jsonObject = new JSONObject(responseString);
String status = String.valueOf(jsonObject.get("a"));

I want to parse "event_locations_array" and what what i done :

JSONArray jsonArray = jsonObject.getJSONArray("event_locations_array");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject points = jsonArray.getJSONObject(i);
JSONObject lat = points.getJSONObject("latitude");
JSONObject lang = points.getJSONObject("longitude");
}
setTextView();
} catch (JSONException e) {
e.printStackTrace();
}
}
here i can't take that jsonArray. what i did wrong here let me know . I'm a little confused
thanks in advance
Fast solution
If you can not change the JSON generation, simply use this code:
#Override
protected void onPostExecute(String result) {
try {
JSONObject jsonObject = new JSONObject(result);
description = jsonObject.getString("event_description");
people_joined = jsonObject.getString("event_hikers_amount");
date_start = jsonObject.getString("event_date_start");
date_end = jsonObject.getString("event_date_end");
time_start = jsonObject.getString("event_time_start");
time_end = jsonObject.getString("event_time_end");
privacy = jsonObject.getString("event_private");
// 1 - fix string to array conversion
JSONArray jsonArray = new JSONArray(jsonObject.getString("event_locations_array"));
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject points = jsonArray.getJSONObject(i);
// 2 - the fields as double
double lat = points.getDouble("latitude");
double lang = points.getDouble("longitude");
}
setTextView();
} catch (JSONException e) {
e.printStackTrace();
}
}
Detailed solution
There are two errors:
The event_locations_array : "[[{"latitude":37.58728984572849].." contains a string. For the value that it's contains I think it must be generated as array (without the initial and final ")
After fix the first problem, you are trying to extract as object the properties latitude and longitude, but they are attributes. So change in your code:
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject points = jsonArray.getJSONObject(i);
JSONObject lat = points.getJSONObject("latitude");
JSONObject lang = points.getJSONObject("longitude");
}
With
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject points = jsonArray.getJSONObject(i);
double lat = points.getDouble("latitude");
double lang = points.getDouble("longitude");
}
To get Values of event_locations_array use following code:
JSONArray jsonArray = jsonResponse.getJSONArray("event_locations_array");
for (int i=0; i<jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String latitude = jsonObject.getString("latitude");
String longitude = jsonObject.getString("longitude");
}
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 want to know how do I access the values of this JSON in Android:
{
"dados": [{
"Id": 3,
"IdChamado": 3,
"Chamado": "value",
"Solicitante": "value",
"Acao": "",
"ItemDeCatalogo": "Mobile | Instalação",
"InicioPrevisto": "06/01/2017 08:11:00",
"TerminoPrevisto": "06/01/2017 08:22:00"
}, {
"Id": 4,
"IdChamado": 4,
"Chamado": "value",
"Solicitante": "value",
"Acao": "",
"ItemDeCatalogo": "value",
"InicioPrevisto": "06/01/2017 08:11:34",
"TerminoPrevisto": "06/01/2017 08:11:34"
}],
"success": true,
"erroAplicacao": false
}
I need to access the values "IdChamado", "chamado", "Solicitante", for example. I've seen nested arrays answers but with jsonObjects having an actual name, like this .
PS: I'm sorry I forgot to post my codes:
//Method called when the doInBack is complete
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray jArray = jsonObject.getJSONArray("dados");
Log.i("***2nd JSON ITSELF***", result);
for (int i=0; i<jArray.length(); i++) {
JSONObject jsonPart = jArray.getJSONObject(i);
int id = jsonPart.getInt("id");
Log.i("***id***", String.valueOf(id));
String chamado = jsonPart.getString("Chamado");
Log.i("***Chamado***", chamado);
String solicitante = jsonPart.getString("solicitante");
Log.i("***Solicitante***", solicitante);
String itemDeCatalogo = jsonPart.getString("itemDeCatalogo");
Log.i("***Item de Catalogo***", itemDeCatalogo);
}
}catch(JSONException e) {
e.printStackTrace();
}// END CATCH
}// END POST EXECUTE
[SOLVED]: Thank you so much people, you are the reason I like to code (Not be afraid of asking stupid questions). It all worked well with the codes you sent as answer. I thought it would be more complicated. xD
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jsonobject = new JSONObject(result);
JSONArray jsonarray = jsonobject.getJSONArray("dados");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jobject = jsonarray.getJSONObject(i);
String idChamado = jobject.getString("IdChamado");
String solicitante = jobject.getString("Solicitante");
Log.i("**id**", idChamado);
Log.i("**solicitante**", solicitante);
}
}catch(JSONException e) {
e.printStackTrace();
}// END CATCH
}// END POST EXECUTE
JSONObject jsonobject = new JSONObject("your JSON String here");
JSONArray jsonarray = jsonobject.getJSONArray("dados");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String IdChamado = jsonobject.getString("IdChamado");
String Solicitante = jsonobject.getString("Solicitante");
}
please try this
try this:
try{
JSONObject json = new JSONObject(jsonString);
JSONArray jsonArray = json.getJSONArray("dados");
for(int i=0;i<jsonArray.length();i++){
JSONObject object = jsonArray.getJSONObject(i);
String IdChamado = object.getString("IdChamado");
String Chamado = object.getString("Chamado");
//rest of the strings..
}
}
catch (JSONException e){
e.printStackTrace();
}
Try this
for (int i=0; i<jArray.length(); i++) {
JSONObject jsonobject = jArray.getJSONObject(i);
int IdChamado = jsonobject.getInt("IdChamado"); //idchamado here
String chamado = jsonobject.getString("Chamado");
String solicitante = jsonobject.getString("Solicitante");
}
Use the correct keys while opting any data
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray jArray = jsonObject.getJSONArray("dados");
Log.i("***2nd JSON ITSELF***", result);
for (int i=0; i<jArray.length(); i++) {
JSONObject jsonObject = new JSONObject(result);
JSONArray jArray = jsonObject.optJSONArray("dados");
Log.i("***2nd JSON ITSELF***", result);
for (int i=0; i<jArray.length(); i++) {
JSONObject jsonPart = jArray.optJSONObject(i);
int id = jsonPart.optInt("Id");
Log.i("***id***", String.valueOf(id));
String chamado = jsonPart.optString("Chamado");
Log.i("***Chamado***", chamado);
String solicitante = jsonPart.optString("Solicitante");
Log.i("***Solicitante***", solicitante);
String itemDeCatalogo = jsonPart.optString("ItemDeCatalogo");
Log.i("***Item de Catalogo***", itemDeCatalogo);
}
}catch(JSONException e) {
e.printStackTrace();
}// END CATCH
}
I wrote a library for parsing and generating JSON in Android
http://github.com/amirdew/JSON
for your sample:
JSON jsonData = new JSON(jsonString);
//access IdChamado of first item:
int IdChamado = jsonData.key("dados").index(0).key("IdChamado").intValue();
//in loop:
JSON dadosList = jsonData.key("dados");
for(int i=0; i<dadosList.count(); i++){
int IdChamado = dadosList.index(i).key("IdChamado").intValue();
String Chamado = dadosList.index(i).key("Chamado").stringValue();
}
I have the following Json. link
I would like to get image_hall_list and image_place_list all url value.
I tried with the following code but no any result.
JSONObject JO = new JSONObject(result);
JSONArray ja = JO.getJSONArray("image_place_list"); //get the array
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = null;
try {
jo = ja.getJSONObject(i);
jsonurl.add(jo.getString("url"));
} catch (JSONException e1) {
e1.printStackTrace();
}
}
Try this:
JSONObject JO = new JSONObject(result);
JSONArray ja = JO.getJSONArray("place_list"); //get the array
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = null;
try {
jo = ja.getJSONObject(i);
JSONArray imageHallList = jo.getJSONArray("image_hall_list");
for (int j = 0; j < imageHallList.length(); j++) {
JSONObject oneImageHallList = imageHallList.getJSONObject(j);
jsonurl.add(oneImageHallList.getString("url"));
}
JSONArray imagePlaceList = jo.getJSONArray("image_place_list");
for (int j = 0; j < imagePlaceList.length(); j++) {
JSONObject oneImagePlaceList = imagePlaceList.getJSONObject(j);
jsonurl.add(oneImagePlaceList.getString("url"));
}
} catch (JSONException e1) {
e1.printStackTrace();
}
}
I would recommend some methods.
One to extract all the URLs for a given object.
public ArrayList<String> getURLs(JSONObject jo, String key) throws JSONException {
List<String> urls = new ArrayList<String>();
JSONArray arr = jo.getJSONArray(key);
for (int j = 0; j < arr.length(); j++) {
JSONObject innerObj = arr.getJSONObject(j);
urls.add(innerObj.getString("url"));
}
return urls;
}
Then, you can use that twice for the respective keys. You also need to first get "place_list" based if your result variable is directly from that link.
try {
JSONObject jsonResponse = new JSONObject(result);
JSONArray ja = jsonResponse.getJSONArray("place_list"); //get the array
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = ja.getJSONObject(i);
jsonurl.addAll(getURLs(jo, "image_hall_list"));
jsonurl.addAll(getURLs(jo, "image_place_list"));
}
} catch (JSONException e1) {
e1.printStackTrace();
}
Use a nested for-loop. First grab the items before the image_hall_list and image_place_list, and then once you have the values stored, loop through image_hall_list, and image_place_list by getting that JSON object and loop through the elements in the JSON objects.
I am trying to get a list of available numbers from the following json object, using the class from org.json
{
"response":true,
"state":1,
"data":
{
"CALLERID":"81101099",
"numbers":
[
"21344111","21772917",
"28511113","29274472",
"29843999","29845591",
"30870001","30870089",
"30870090","30870091"
]
}
}
My first steps were, after receiving the json object from the web service:
jsonObj = new JSONObject(response);
jsonData = jsonObj.optJSONObject("data");
Now, how do I save the string array of numbers?
use:
jsonObj = new JSONObject(response);
jsonData = jsonObj.optJSONObject("data");
JSONArray arrJson = jsonData.getJSONArray("numbers");
String[] arr = new String[arrJson.length()];
for(int i = 0; i < arrJson.length(); i++)
arr[i] = arrJson.getString(i);
you need to use JSONArray to pull data in an array
JSONObject jObj= new JSONObject(your_json_response);
JSONArray array = jObj.getJSONArray("data");
Assuming that you are trying to get it in a javascript block, Try something like this
var arrNumber = jsonData.numbers;
My code is for getting "data":
public void jsonParserArray(String json) {
String [] resultsNumbers = new String[100];
try {
JSONObject jsonObjectGetData = new JSONObject(json);
JSONObject jsonObjectGetNumbers = jsonObjectGetData.optJSONObject("results");
JSONArray jsonArray = jsonObjectGetNumbers.getJSONArray("numbers");
for (int i = 0; i < jsonArray.length(); i++) {
resultsNumbers[i] = jsonArray.getString(i);
}
} catch (JSONException e) {
e.printStackTrace();
Log.e(LOG_TAG, e.toString());
}
}
