Combining nested json for loop

I have two forloop in which the data is added to different ArrayList. Now my question is how do we combine these two arraylist?
Below is the code which i tried, but not working. Please give me solution for the same. TIA
try {
JSONObject object = new JSONObject(response);
status = object.getString("status");
if (status.equals("200")) {
rest.dismissProgressdialog();
JSONArray jsonArray = object.getJSONArray("data");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
New_Service_Model_1 new_service_model = new New_Service_Model_1();
new_service_model.setMain_name(jsonObject.getString("main_name"));
new_service_model.setSmid(jsonObject.optInt("smid"));
JSONArray jsonArray1 = jsonObject.getJSONArray("sub_service");
//sub_services_list.clear();
sub_services_list = new ArrayList<>();
for (int j = 0; j < jsonArray1.length(); j++) {
JSONObject jsonObject1 = jsonArray1.getJSONObject(j);
New_Sub_Service_Model_1 sub_service_model = new New_Sub_Service_Model_1();
sub_service_model.setSmid(jsonObject1.optString("smid"));
sub_service_model.setSbid(jsonObject1.optInt("sbid"));
sub_service_model.setSub_name(jsonObject1.optString("sub_name"));
sub_service_model.setDesc(jsonObject1.optInt("desc"));
sub_service_model.setSt_cust(jsonObject1.optInt("st_cust"));
sub_service_model.setSt_pro(jsonObject1.optInt("st_pro"));
sub_service_model.setExist_cust(jsonObject1.optInt("exist_cust"));
sub_service_model.setExist_prov(jsonObject1.optInt("exist_prov"));
sub_services_list.add(sub_service_model);
}
new_service_model.setSub_service_list(sub_services_list);
services_list.add(new_service_model);
service_list_adapter = new Service_List_Adapter_1(this, services_list, service_costMain_interface);
rclyrview_services.setAdapter(service_list_adapter);
service_list_adapter.notifyDataSetChanged();
}
} else {
rest.dismissProgressdialog();
Toast.makeText(Service_Manage.this, "No Data found", Toast.LENGTH_SHORT).show();
}

Instead of parsing the json response manually.
Paste you json here http://www.jsonschema2pojo.org/ and use GSON or Jackson whichever is convenient for parsing the response.
There are many tutorials available which can give you a quick overview of how things can be done. Worth a try if your app has many places where you want to have Json parsing.

error while parsing an jsonarray

I am making a webservice call and the respond is in JSON.
The content which i get, is a JSONArray and looks like this:
{"jsonrpc":"2.0","id":"req-002","result":[
{"id":125043,"date":20110117,"startTime":800,"endTime":850,
"kl":[{"id":71}],"te":[{"id":23}],"su":[{"id":13}],"ro":[{"id":1}]},
{"id":125127,"date":20110117,"startTime":1055,"endTime":1145,
"kl":[{"id":71}],"te":[{"id":41}],"su":[{"id":19}],"ro":[{"id":31}]},
]}
Now i am trying to get the objects in the array, but i am only able to fetch the first array: for example i cant get the first "kl" array but i am not able to get the second one.
It always give me the error :
org.json.JSONException: Index 1 out of range [0..1)
This is what i have tried:
JSONObject jsonResult = new JSONObject(s);
// Get the result object
JSONArray arr = jsonResult.getJSONArray("result");
Log.d("Arraylänge", String.valueOf(arr.length()));
for(int i=0; i<arr.length(); i++){
JSONObject c = arr.getJSONObject(i);
anfangStunde[i] = c.getString("startTime");
endeStunde[i] = c.getString("endTime");
JSONArray klArr = c.getJSONArray("kl");
for(int j=0; i<klArr.length(); j++)
{
JSONObject k = klArr.getJSONObject(j);
klassenID[j] = k.getString("id");
}

You have a typo for(int j=0; **i**<klArr.length(); j++)

How to parse JSON Array in android?

I have a JSON Array as follows:
jSONArray: {"li":[["apple\r\n","orange\r\n","mango\r\n"]]}
I want only the list as [apple, orange, mango] in android. Can anybody explain how to parse it in android without \r\n. I have tried as follows:
JSONArray jsonArray1 = new JSONArray(results.toString()); // which is the JSON Array
for(int i=0; i < jsonArray1.length(); i++) {
JSONObject jsonobject = new JSONObject();
JSONObject issue = jsonArray1.getJSONObject(i);
String _pubKey = issue.getString("li");
}
So, I am getting pubKey as [["apple\r\n","orange\r\n","mango\r\n"]]. I dont want \r\n.

Just replace those characters while parsing.
Example: If fruit is the string you want to put in your JSONArray jsonArray, call:
jsonArray.put(fruit.trim().replace("\r", "").replace("\n", ""));

How to split this kind of data in android

Here is the
string one =[{"ID":5,"Name":"Sai"}]
how i get only id and name from this string
Matcher matcher = Pattern.compile("\\[([^\\]]+)").matcher(one);
List<String> tags = new ArrayList<String>();
int pos = -1;
while (matcher.find(pos+1)){
pos = matcher.start();
tags.add(matcher.group(1));
}
System.out.println("getting data"+tags);
i tried this but it didn't work

List<String> ls = new ArrayList<String>(one);
JSONArray array = new JSONArray();
for(int i = 0; i< array.length(); i++){
JSONObject obj = array.getJSONObject(i);
ls.add(obj.getString("Name"));
}

It's JSON format and it can very easily be read in Android. Here is the sample code:
JSONArray array = new JSONArray(one);
int length = array.length();
for(int i=0;i< length; i++)
{
JSONObject temp = array.getJSONObject(i);
System.out.println(temp.getString("ID"));
System.out.println(temp.getString("Name"));
}

This format of data is called JSON.
Have a look at Go to http://json.org/, scroll to (almost) the end, click on one of the many Java libraries listed.

First of all, your string initialization is wrong.
Wrong:
string one =[{"ID":5,"Name":"Sai"}]
Correct:
String one ="[{\"ID\":5,\"Name\":\"Sai\"}]";
Second, its a JSON formatted data so you can parse it using JSONArray and JSONObject classes, instead of creating any pattern.
Now, in your case its JSONObject inside JSONArray so initially create an object of JSONArray using your string.
For example:
JSONArray arrayJSON = new JSONArray(one); // 'one' is your JSON String
for(int i=0; i<arrayJSON.length(); i++) {
JSONObject objJson = arrayJSON.getJSONObject(i);
String ID = objJson.getString("ID");
.....
.....
// same way you can fetch/parse any string/value from JSONObject/JSONArray
}

it is a json formate Date
use JsonObject class to parse this data
tutorial this
JSONArray jsonArray = new JSONArray("[{\"ID\":5,\"Name\":\"Sai\"}]");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject object = jsonArray.getJSONObject(i);
System.out.println(object.getString("ID"));
System.out.println(object.getString("Name"));
}

Json data extracting in android

i want to extract the given json arry in android,
[{"Outofserviceday":{"outofservice":"2013-02-22"}},
{"Outofserviceday":{"outofservice":"2013-02-27"}},
{"Outofserviceday":{"outofservice":"2013-02-28"}}]
i have the code for extracting the json data like given below
[{"Requestcard":{"id":"994","userprofile_id":"14","userprofile_name":"Syed
Imran","company_name":"DLF Akruti Park, Hinjewadi, Pune,
Maharashtra","sex":"male","travel_date":"2013-02-12"}}]
in this case we can retrive the json boject using the code
JSONObject menuObject = json_data.getJSONObject("Requestcard");
and retrieve each element by
requestid= menuObject.getString("id");
But in the first case how we identify each Outofserviceday in the json array ? and How extract each data ???

you can do something like below, can create jsonArray from string json data and then can extracts json objects in a loop or so.
String json =" [{\"Outofserviceday\":{\"outofservice\":\"2013-02-22\"}}]"; //json-data which is basically a json array
JSONArray jArray = new JSONArray(json); / creating an jsonarray
for (int i = 0; i < jArray.length(); i++) {
// you can have jsonObject from json array here in the loop
}

Try this:
JSONObject json = new JSONObject(result);
JSONArray json1= json.getJSONArray("data");
if (json1.length()!=0) {
for (int i = 0; i < json1.length(); i++) {
String name = json1.getJSONObject(i).getString("name");
}
}

With the help of below code you can retrieve the value of outofservice
JSONArray jArray = new JSONArray(your data);
for (int i = 0; i < jArray.length(); i++) {
JSONObject jOutOfServiceDay = jArray.getJSONObject(i);
JSONObject jobj = jOutOfServiceDay.getJSONObject("Outofserviceday");
Log.i("Required data is:", "" + jobj.getString("outofservice"));
}
