Android Multiple Level JsonObject and JsonArray Parsing with Model class

{
"Query":"query",
"KMAQuery":"query",
"TotalCount":3,
"Data":[{"CollName":"kmdb_new",
"TotalCount":3,
"Count":3,
"Result":[{"title":"sampletitle",
"director":[{"directorNm":"name1","directorId":"00004544"}],
"nation":"nation1",

"rating":[{"ratingMain":"Y","ratingDate":"19640717","ratingNo":"","ratingGrade":"","releaseDate":"","runtime":""}]]}
Here is my Json Data from OKHttp parsing.
Actually There is many same Result 2~3.
I want to parsing key name "title", "directorNm", "nation", "company", "ratingGrade" and set Model class.
How to parsing multiple Json Object and Array with Gson into Model class?
I'm finally going to use the recyclerview with model class.
If you tell me how to parsing "title" and "directorNm", I can do to rest.
For reference, I am using a AsyncTask, OKHttp, Gson etc.
If you don't understand my question or need code, please comment!
I need your help vigorously.

Here I am sharing the code settting response from Model(Pojo Class)
public void getResponse(JSONObject jsonObject){
try {
JSONObject responseJson = new JSONObject(jsonObject.toString());
JSONArray jsonArray = responseJson.getJSONArray("heroes");
for (int i = 0; i < jsonArray.length(); i++){
//getting the json object of the particular index inside the array
JSONObject jsonObject = jsonArray.getJSONObject(i);
YourPojoClass pojoObject = new YourPojoClass();
pojoObject.setName(jsonObject.getString("name"));
pojoObject.setImageurl(jsonObject.getString("imageurl"));
}
} catch (JSONException e) {
e.printStackTrace();
}
}

Parsing JsonArray With JsonObject

I have some JSON with the following structure:
{
"items":[
{
"product":{
"product_id":"some",
"price_id":"some",
"price":"some",
"title_fa":"some",
"title_en":"Huawei Ascend Y300",
"img":"some",
"has_discount_from_price":"0",
"discount_from_price":null,
"type_discount_from_price":null,
"has_discount_from_product":"0",
"discount_from_product":null,
"type_discount_from_product":null,
"has_discount_from_category":"0",
"discount_from_category":null,
"type_discount_from_category":null,
"has_discount_from_brand":"0",
"discount_from_brand":null,
"type_discount_from_brand":null,
"weight":null,
"features":[
{
"feature_value":"#000000",
"feature_id":"some",
"feature_title":"some"
},
{
"feature_value":"some",
"feature_id":"1652",
"feature_title":"some"
}
]
},
"number":1,
"feature_id":"56491,56493",
"price_inf":{
"has_discount":0,
"discount_type":0,
"final_price":"400000",
"value_discount":0
},
"cart_id":13
}
]
}
I'm trying to access the elements "product_id" and "price_id" with the following Java code:
try{
JSONArray feedArray=response.getJSONArray("items");
for (int i=0;i<feedArray.length();i++){
JSONObject feedObj=feedArray.getJSONObject(i);
JSONObject pro=feedObj.getJSONObject("product");
Product product = new Product();
product.setPrice(pro.getDouble("price_id"));
product.setTitle_fa(pro.getString("price_id"));}}
but i see product not found error.what is wrong in my parser?

First of all your JSON is valid. So no worries there.
Now regarding your problem, because you haven't posted the logs so I can't tell what the exact problem is. But using this code snippet you can get the desired values.
try {
JSONArray itemsJsonArray = jsonObject.getJSONArray("items");
for (int i = 0; i < itemsJsonArray.length(); i++){
JSONObject itemJsonObject = itemsJsonArray.getJSONObject(i);
JSONObject productObject = itemJsonObject.getJSONObject("product");
String productId = productObject.getString("product_id");
String priceId = productObject.getString("price_id");
}
} catch (JSONException e) {
e.printStackTrace();
}

Validate and create Pojo for your json here
use
Data data = gson.fromJson(this.json, Data.class);
follow https://stackoverflow.com/a/5314988/5202007
By the way your JSON is invalid .

you are getting a json object from your response not json array you need to make following changes
JSONObject temp =new JSONObject(response);
JSONArray feedArray=temp.getJSONArray("items");

Try converting response string to JSONObject first
try{
JSONObject temp =new JSONObject(responseString); // response is a string
JSONArray feedArray=.getJSONArray("items");
....
}
You may try to use GSON library for parsing a JSON string. Here's an example how to use GSON,
Gson gson = new Gson(); // Or use new GsonBuilder().create();
MyType target = new MyType();
String json = gson.toJson(target); // serializes target to Json
MyType target2 = gson.fromJson(json, MyType.class); // deserializes json into target2

How to get json array values in android?

JSON response value looks like this "types" : [ "sublocality", "political" ]. How to get the first value of the types or how to get the word sublocality?

String string = yourjson;
JSONObject o = new JSONObject(yourjson);
JSONArray a = o.getJSONArray("types");
for (int i = 0; i < a.length(); i++) {
Log.d("Type", a.getString(i));
}
This would be correct if you were parsing only the line you provided above. Note that to access types from GoogleMaps geocode you should get an array of results, than address_components, then you can access object components.getJSONObject(index).
This is a simple implementation that parses only formatted_address - what I needed in my project.
private void parseJson(List<Address> address, int maxResults, byte[] data)
{
try {
String json = new String(data, "UTF-8");
JSONObject o = new JSONObject(json);
String status = o.getString("status");
if (status.equals(STATUS_OK)) {
JSONArray a = o.getJSONArray("results");
for (int i = 0; i < maxResults && i < a.length(); i++) {
Address current = new Address(Locale.getDefault());
JSONObject item = a.getJSONObject(i);
current.setFeatureName(item.getString("formatted_address"));
JSONObject location = item.getJSONObject("geometry")
.getJSONObject("location");
current.setLatitude(location.getDouble("lat"));
current.setLongitude(location.getDouble("lng"));
address.add(current);
}
}
catch (Throwable e) {
e.printStackTrace();
}
}

You should parse that JSON to get those values. You can either use JSONObject and JSONArray classes in Android or use a library like Google GSON to get the POJOs from JSON.

I would insist you to use GSON. I had created a demo for parsing the same map response. You can find the complete demo here. Also I had created a global GSON parser class that can be used to parse any response that is in JSON with ease.

How to get location from Google Place API JSON (android)

I have type below to get Location array to get the latitude, but it can not work.
Is it any mistake in my code? And i can get the result, but i cannot get geometry.
JSONTokener jsonParser = new JSONTokener(strResult);
JSONObject jsonObject = new JSONObject(strResult);
JSONArray routeObject = jsonObject.getJSONArray("results");
routeObject.getJSONObject(0).getJSONArray("geometry").getJSONObject(0).getJSONArray("location").getJSONObject(0).getDouble("lat")

I do it in this way:
The google maps url:
http://maps.google.com/maps/geo?q="+fullAddress;
And I read it:
JSONObject response = new JSONObject(result);
JSONObject point = response.getJSONArray("Placemark").getJSONObject(0).getJSONObject("Point");
lat = point.getJSONArray("coordinates").getString(1);
lng = point.getJSONArray("coordinates").getString(0);
Hope it helps!

I never used google-places-api, but I just tried something. I just toke the example file from https://developers.google.com/maps/documentation/places/ place-search-response and copied it to a file as input. (edit: I am using http://code.google.com/p/google-gson/ to decode)
My code to decode the JsonFile looks like that and gives you the latitude you are looking for:
JsonParser parser = new JsonParser();
JsonObject obj = (JsonObject)parser.parse(new FileReader(path));
for(Entry<String, JsonElement> entry : obj.entrySet()) {
String key = entry.getKey();
System.out.println(key);
if(key.trim().equals("results".trim())) {
for(JsonElement ele2 : entry.getValue().getAsJsonArray()) {
System.out.println(ele2.getAsJsonObject().get("geometry").getAsJsonObject().get("location").getAsJsonObject().get("lat"));
}
}
}

How to parse json url using android?

I want parse json url,my json url contains following structures
{"content":{"item":[{"category":"xxx"},{"category":"yy"} ]}}
how to read this structure,anybody knows give example json parser for that.
Thanks

This code will help you to parse yours json.
String jsonStr = "{\"content\":{\"item\":[{\"category\":\"xxx\"},{\"category\":\"yy\"} ]}}";
try {
ArrayList<String> categories = new ArrayList<String>();
JSONObject obj = new JSONObject(jsonStr);
JSONObject content = obj.getJSONObject("content");
JSONArray array = content.getJSONArray("item");
for(int i = 0, count = array.length();i<count;i++)
{
JSONObject categoty = array.getJSONObject(i);
categories.add(categoty.getString("category"));
}
} catch (JSONException e) {
e.printStackTrace();
}

JSONObject can do the parsing.

You need to use the org.json's package.
Example:
For an object:
JSONObject json = new JSONObject(json_string);
For an array:
JSONArray json = new JSONArray(json_string);
