I'm retrieving the following JSON from a web service:
["test_w","\u062a\u0637\u0628\u064a\u0642 \u0631\u0642\u0645 3","\u062a\u0637\u0628
\u064a \u0642 \u0631\u0642\u0645 2","\u062a\u0637\u0628\u064a\u0642 \u0631\u0642\u0645
1","test_333","\u0645\u0639\u0631\u0641\u0629 \u0627\u0644\u062a\u0627\u0621 \u0627\u0644
\u0645\u0631\u0628\u0648\u0637\u0629 \u0648\u062a\u0646\u0648\u064a\u0646 \u0627\u0644
\u0636\u0645","\u0639\u0644\u0648\u0645","\u0648\u0631\u0642\u0629 \u0639\u0645\u0644"]
As you can see, it's not in name, value format; I tried accessing the JsonObject itself but it's always returning null:
JSONArray jArray = new JSONArray(resultLine);
for (int i = 0; i < jArray.length(); i++) {
JSONObject json_data = jArray.getJSONObject(i);
notifArray.add(json_data.toString());
Is there any way to deal with this particular format of JSON ?
You have an array of strings. So you have to use getString (or optString) to access the array elements:
JSONArray jArray = new JSONArray(resultLine);
for (int i = 0; i < jArray.length(); i++) {
String str = jArray.getString(i);
notifArray.add(str);
}
JSONArray jArray = new JSONArray(resultLine);
for (int i = 0; i < jArray.length(); i++) {
notifArray.add(jArray.get(i));
}

I want to display updated_at data to user only if value of password in folder Array is null.
JSONArray jsonArray = object.getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject dataa = jsonArray.getJSONObject(i);
JSONArray jsonArray2 = dataa.getJSONArray("folder");
for (int i2 = 0; i2 < jsonArray.length(); i2++)
{
JSONObject dataa2 = jsonArray2.getJSONObject(i2);
String password = dataa2.getString("password");
if (password.equals("null") || password.equals(null))
{
//Display data
}
else
{
// dont Display data
}
}
Is there a way to do it?
Rectify your inner loop condition section.
JSONArray jsonArray2 = dataa.getJSONArray("folder");
for (int i2 = 0; i2 < jsonArray2.length(); i2++)
{
JSONObject dataa2 = jsonArray2.getJSONObject(i2);
These are my JSON data:
[
{"haberBaslik":"ekrem kimdir?"},
{"haberBaslik":"doğa kimdir?"},
{"haberBaslik":"biz kimiz?"},
{"haberBaslik":"fatih naptı?"}
]
and this code only shows the latest data, but I need to show my all data
JSONArray jsonarray = new JSONArray(s);
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String Haberbaslik = jsonobject.getString("haberBaslik");
tv1.setText(Haberbaslik);
}
JSONArray jsonarray = new JSONArray(s);
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String Haberbaslik = jsonobject.getString("haberBaslik");
tv1.setText(tv1.getText()+ " "+Haberbaslik);
}
I'm trying to get the values from array in a JSON file. Array only has a square brackets and not curly brackets something like this:
"{"name_of_the_array: ["value_1", "value_2"]"}"
I found here some answer but it did not work for me the code of the answer is:
JSONArray array = new JSONArray("array_name");
for (int i = 0; i < array.length(); i++) {
str = array.get(i).toString();
list.add(str);
}
the list is ArrayList list.
{} denotes a JSONObject so you have to create a JSONObject first. [] denotes a JSONArray. You have to fetch the JSONArray from JSONObject with key.
Use this code
JSONObject jsonObject = new JSONObject(jsonString);
JSONArray array = jsonObject.getJSONArray("array_name");
for (int i = 0; i < array.length(); i++) {
str = array.get(i).toString();
list.add(str);
}
Check this and this for parsing
try something like this
JSONArray array = new JSONArray("array_name");
for (int i = 0; i < array.length(); i++) {
str = array.getJSONObject(i).getString("string_name");
list.add(str);
}
or you can try this too
JSONArray array = new JSONArray("array_name");
for (int i = 0; i < array.length(); i++) {
str = array.getString("string_name");
list.add(str);
}
I cannot figure out why my parsing is not working, this is my JSON:
{
"fileVersion":"1.0",
"graves":[
{
"ID_grave":"1",
"ID_line":"1",
"sequence":"1",
"persons":[
{
"ID_person":"1",
"name":"Janez",
"surname":"Novak",
"dateBirth":"1956-08-11",
"dateDeath":"2014-02-12",
"important":"0",
"imp_desc":""
}
]
},
{
"ID_grave":"2",
"ID_line":"1",
"sequence":"2",
"persons":[
{
"ID_person":"2",
"name":"Mojca",
"surname":"Novak",
"dateBirth":"1953-02-13",
"dateDeath":"2012-04-08",
"important":"0",
"imp_desc":""
}
]
}
]
}
This code is working, when I want to get the first JSONObject:
String jsonData = convertStreamToString(in);
JSONObject json = new JSONObject(jsonData);
JSONArray name = json.getJSONArray("graves");
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
lineArrayList.add(grave.getString("ID_line"));
graveArrayList.add(grave.getString("ID_grave"));
}
But I would like to get the "persons" array in "graves" object. This should work but it's not, I am getting only the first persons array, where the name is Janez and not the second array where the name is Mojca:
String jsonData = convertStreamToString(in);
JSONObject json = new JSONObject(jsonData);
JSONArray name = json.getJSONArray("graves");
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.getJSONArray("persons");
for (int k = 0; k < persons.length(); k++) {
//The problem was because of the index i, you have to change to k and it will work
JSONObject grave = persons.getJSONObject(i);
nameArrayList.add(grave.getString("name"));
surnameArrayList.add(grave.getString("surname"));
}
}
graves is a JSONArray and persons is a JSONArray into graves
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.optJSONArray("persons");
if (persons != null) {
for (int j = 0; j < persons.length(); j++) {
}
}
}
Do your parsing as follows ,
String jsonData = convertStreamToString(in);
JSONObject json = new JSONObject(jsonData);
JSONArray name = json.getJSONArray("graves");
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.getJSONArray("persons");
for (int k = 0; k < persons.length(); k++) {
JSONObject grave = persons.getJSONObject(i);
nameArrayList.add(grave.getString("name"));
surnameArrayList.add(grave.getString("surname"));
}
}
Try This:
for (int i = 0; i < name.length(); i++) {
JSONObject grave = name.getJSONObject(i);
JSONArray persons = grave.optJSONArray("persons");
if (persons != null) {
for (int j = 0; j < persons.length(); j++) {
JSONObject grave= persons.getJSONObject(i);
lineArrayList.add(grave.getString("ID_line"));
//so on..
}
}
Ok only today I discovered that I am getting the data only from the first persons array and from the second where for example is a person with a name Mojca..I tried all the three given solutions but nothing works..
I have a JSONObject with the data structure as follows
[{"distance":"200 meters","location_id":"519"},{"distance":"300 meters","location_id":"219"}]
and I'm trying to traverse each array within that object, I have the following code where locationArray is the valid JSONObject
for (int j = 0; j < locationArray.length(); j++) {
JSONObject j_obj;
j_obj = locationArray.getJSONArray(j); //error here
location_id = j_obj.getString("location_id");
}
but i'm getting an error trying to find each sub array of locationArray with an integer.
the solution:
JSONArray rootArray = new JSONArray(jsonString);
int len = rootArray.length();
for(int i = 0; i < len; ++i) {
JSONObject obj = rootArray.getJSONObject(i);
location_id = obj.getString("location_id");
}
There is an error in your code. j_obj = locationArray.getJSONArray(j); should be j_obj = locationArray.getJSONObject(j);, as the object wrapped with curly braces represents a JSONObject and not a JSONArray
Edit: you may consider using obj.optString("location_id"); to avoid a potential problem
