i want to parse data like below format in this format there are no any left side value for parse it so any idea how can i make it possible
JSON FORMAT
{
"labels": [
"Dec-2014",
"Jan-2015",
"Feb-2015",
"Mar-2015",
"Apr-2015",
"May-2015"
],
"data": [
0,
0,
0,
0,
0,
0
]
}
Try this
try {
JSONObject jsonObject = new JSONObject(
"{\"labels\": [\"Dec-2014\",\"Jan-2015\",\"Feb-2015\",\"Mar-2015\",\"Apr-2015\",\"May-2015\"],\"data\": [0,0,0,0,0,0]}");
JSONArray array = jsonObject.getJSONArray("labels");
for (int i = 0; i < array.length(); i++) {
String s = (String) array.get(i);
System.out.println(s);
}
JSONArray array2 = jsonObject.getJSONArray("data");
for (int i = 0; i < array2.length(); i++) {
String s = (String) array2.get(i);
System.out.println(s);
}
} catch (Exception e) {
}
Hope this will solve your problem!!!
You can get jsonData as follows.
JSONObject jsonObj=new JSONObject(urJson);
JSONArray labels=jsonObj.getJSONArray("labels");
ArrayList<String> lableList=new ArrayList<String>();
for (int i = 0; i < labels.length();i++)
{
lableList.add(labels.getString(i));
}
JSONArray data=jsonObj.getJSONArray("data");
ArrayList<String> dataList=new ArrayList<String>();
for (int i = 0; i < data.length();i++)
{
dataList.add(data.getString(i));
}
There are two array objects in your current Json, You can extract it as given below
// Data json array
JSONArray dataArry = obj.getJSONArray("genre");
ArrayList<String> data = new ArrayList<String>();
for (int j = 0; j < dataArry.length(); j++)
{
data.add((String) dataArry.get(j));
}
Same logic can be applied for labels too

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 have a json which has multiple values separated by commas which is in the
form of array.I want to get skills and platforms string separately.Can you please help me?
I want to show skills string and platforms string in text.
Please help me.
The format is:
{
"data": [
{
"skills": "ANDROID SDK, ANIMATION, ANGULARJS,",
"platforms": "IOS Application, Social Networking, Online shopping Sites, Web Application"
}
],
"status": 100
}
Try this one
try {
JSONObject ob = new JSONObject(response);
int status = ob.getInt("status");
if (status == 100) {
JSONArray ja = ob.getJSONArray("data");
for (int i = 0; i < ja.length(); i++) {
values = new HashMap<>();
JSONObject vj = ja.getJSONObject(i);
String skills = vj.getString("skills "));
String platforms=vj.getString("platforms"));
data.add(values);
}
split these 2 strings using 'split()'
List<String> skillsArray = Arrays.asList(skills.split(","));
List<String> platformsArray= Arrays.asList(platforms.split(","));
String in = "your json";
JSONObject jsonObj = new JSONObject(in);
// Getting JSON Array node
JSONArray jsonarray = jsonObj.getJSONArray("data");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String skills = jsonobject.getString("skills");
String platforms = jsonobject.getString("platforms");
}
Try this
JSONObject jsonObject = new JSONObject("Your json response");
JSONArray jsonArray = jsonObject.getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonobject = jsonArray.getJSONObject(i);
String skill = jsonobject.getString("skills");
String platforms = jsonobject.getString("platforms");
String[] skillsArray = skill.split(Pattern.quote(","));
String[] platformsArray = platforms.split(Pattern.quote(","));
for (int j=0; j<skillsArray.length; j++)
{
Log.i("Skill Value ", "=" + skillsArray[j]);
}
for (int j=0; j<platformsArray.length; j++)
{
Log.i("platforms Value ", "=" + platformsArray[j]);
}
}
Output
First of all convert your output string into json. Note that output string is the string which contains your results of json format that you have posted above.following is the code on how to do that:
JSONObject myJsonResponse = new JSONObject(yourString);
The next one is Array. That is how you will get it and will iterate over it.
JSONArray jsonarray = jsonObj.getJSONArray("data");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject innerJsonObject= jsonarray.getJSONObject(i);
String skills = innerJsonObject.getString("skills");
String platforms = innerJsonObject.getString("platforms");
}
Now you have gotten your required fields and you can now perform any String functions over the String skills and platforms.
Happy coding. .
The best way is creating a model class such :
public class MyModel{
Properties [] data;
class Properties{
public String skills;
public String platforms;
}
}
then you can parse your string to model with Gson library like this :
MyModel myModel = new Gson().fromJson(yourString, MyModel.class)
so all data is in myModel object and you can access to skills with
myModel.data[0].skills
to add Gson library to your project add below to your app gradle file :
compile 'com.google.code.gson:gson:2.8.1'
You may try this,
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject("JSON_STRING");
JSONArray jsonArray = jsonObject.getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonobject = jsonArray.getJSONObject(i);
String skills = jsonobject.getString("skills");
String[] seperateData = skills.split(Pattern.quote(","));
for (int j = 0; j < seperateData.length; j++) {
Log.e("Your Skill Value-> ", seperateData[j]);
}
String platforms = jsonobject.getString("platforms");
seperateData = platforms.split(Pattern.quote(","));
for (int j = 0; j < seperateData.length; j++) {
Log.e("Your Platform Value-> ", seperateData[j]);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
class Data{
public String skills;
public String platforms;
}
Gson gson = new Gson();
JSONArray dataArray = response.getJSONArray("data");
List<Data> dataList= gson.fromJson(dataArray toString(), new TypeToken<List<Data>>() {
}.getType());
Try this.. It will make parsing easier.
implementation 'com.google.code.gson:gson:2.8.0'
First Parse your JSON:
JSONObject jsonObj = new JSONObject(in);
JSONArray jsonarray = jsonObj.getJSONArray("data");
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonobject = jsonarray.getJSONObject(i);
String skills = jsonobject.getString("skills");
String platforms = jsonobject.getString("platforms");
}
Then Split your string values:
String skills = "ANDROID SDK, ANIMATION, ANGULARJS";
String[] separated = CurrentString.split(",");
separated[0]; // this will contain "ANDROID SDK"
separated[1]; // this will contain " ANIMATION"
separated[2]; // this will contain " ANGULARJS"
You have to remove the space to the second String:
separated[1] = separated[1].trim();
Try this you will be getting all values of sapereted with commas
jsonString = getting string from server side
String[] separated = jsonString.split(",");
StringBuilder s = new StringBuilder(10000);
for (int i = 0; i < separated.length; i++) {
if (i == separated.length - 1) {
s.append(separated[i].trim() + "");
} else {
s.append(separated[i].trim() + ",\n");
}
}
//tvDisplayAddress.setText(s);
Log.e("VALUES: ",s+"");
I have the following JSON struncture:
{
"schedule":{
"day":[
{
"id":"Monday",
"items":[
{
},
{
}
]
},
{
"id":"Tuesday",
"items":[
{
},
{
}
]
}
]
}
}
And what I basically want to do is reach the items array inside the day array which is inside the schedule object.
But whenever I try to get the second JSON array, I get getJSONArray
(int) in JSONArray cannot be applied to (java.lang.String).
JSONObject baseJsonResponse = new JSONObject(dayJSON);
JSONArray dayArray = baseJsonResponse.getJSONObject("schedule").getJSONArray("day").getJSONArray("items");
You should use Two for loop respect to JSONArray.
JSONObject obj = new JSONObject(success);
JSONObject JOBJ_Schedule = obj.getJSONObject("schedule");
JSONArray schedule_Array = JOBJ_Schedule.getJSONArray("day");
for (int i = 0; i < schedule_Array.length(); i++)
{
JSONObject jOBJ = schedule_Array.getJSONObject(i);
JSONArray jArray = jOBJ.getJSONArray("items");
for (int j = 0; j < jArray.length(); j++)
{
JSONObject jOBJNEW = jArray.getJSONObject(j);
}
}
Looks like day is a list of objects. So basically, you'd have to do something like getJSONArray("day").get(0).getJSONArray("items").
you can try this
try {
JSONObject baseJsonResponse = new JSONObject("dayJSON");
JSONObject schedule= baseJsonResponse.getJSONObject("schedule");
JSONArray day=schedule.optJSONArray("day");
for (int i=0; i<day.length(); i++) {
JSONObject data = day.getJSONObject(i);
String id = data.getString("id");
JSONArray items = data.getJSONArray("items");
for (int j = 0; j < items.length(); j++) {
JSONObject data2 = day.getJSONObject(i);
String str = data2.getString("YOurkey");
Log.e("categories", str);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
According to the JSON you provided, baseJsonResponse.getJSONObject("schedule").getJSONArray("day") will return you a JSONArray instead of JSONObject.
There is a "item" JSONArray inside each "day" JSONObject. < May be this is the reason.
You can try
for(int i = 0 ; i < baseJsonResponse.getJSONObject("schedule").getJSONArray("day").length() ; i++){
JSONArray itemArray = baseJsonResponse.getJSONObject("schedule").getJSONArray("day")
.getJSONObject(i).getJSONArray("items");
}
I'm having trouble getting the String "lf" in this case North Atlantic Treaty Organization
[
{
"sf": "NATO",
"lfs": [
{
"lf": "North Atlantic Treaty Organization",
"freq": 13,
"since": 2001,
"vars": [
{
"lf": "North Atlantic Treaty Organization",
"freq": 13,
"since": 2001
}
]
}
]
}
]
//MY CODE
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray jsonArray = jsonObject.getJSONArray(ITEM_TAG);
for(int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
String name = c.getString("lf");
acronyms = new ArrayList<>();
acronyms.add(name);
}
} catch (Exception e) {
}
try {
JSONArray jsonArray1 = new JSONArray(JsonString);
for (int i = 0; i <= jsonArray1.length(); i++) {
JSONObject jsonObject2 = jsonArray1.getJSONObject(i);
String mStrSf = jsonObject2.getString("sf");
Toast.makeText(getApplicationContext(),mStrSf.toString(), Toast.LENGTH_LONG).show();
JSONArray jsonArray3 = jsonObject2.getJSONArray("lfs");
for (int j = 0; j <= jsonArray3.length(); j++) {
JSONObject jsonObject4 = jsonArray3.getJSONObject(j);
String mStrIf = jsonObject4.getString("lf");
String mStrFreq = jsonObject4.getString("freq");
String mStrSince = jsonObject4.getString("since");
Toast.makeText(getApplicationContext(),mStrIf+"\n"+mStrFreq+"\n"+mStrSince, Toast.LENGTH_LONG).show();
JSONArray jsonArray5 = jsonObject4.getJSONArray("vars");
for (int k = 0; k <= jsonArray5.length(); k++) {
JSONObject jsonObject6 = jsonArray5.getJSONObject(k);
String mStrIf1 = jsonObject6.getString("lf");
String mStrFreq1 = jsonObject6.getString("freq");
String mStrSince1 = jsonObject6.getString("since");
Toast.makeText(getApplicationContext(),mStrIf1+"\n"+mStrFreq1+"\n"+mStrSince1, Toast.LENGTH_LONG).show();
}
}
}
} catch (JSONException e) {
e.printStackTrace();
}
You are interpreting the json in a wrong way... if you analyse the json chain you will get this:
as you can see you have an array inside and array...
hope the picture helps you to see it better.
You have to again loop through the jsonArray to get "lf" key value.
Try this...
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray jsonArray = jsonObject.getJSONArray(ITEM_TAG);
for(int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
JSONArray array = c.getJSONArray("lfs");
for(int j=0;j<array.length();j++){
JSONObject obj = array.getJSONObject(j);
String name = obj.getString("lf");
}
}
} catch (Exception e) {
}
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..
