I have Json through which i have to retrieve objects but unable to retrieve.
I have used multiple objects also to retrieve but no success.
JSON:
{
"status": 1,
"data": [{
"restaurent_id": "1",
"user_id": "6",
"zone_id": "1",
"restaurentAddress": {
"restaurent_address_id": "1"
},
"restaurentInfo": {
"restaurent_info_id": "1",
"restaurent_bussiness_owner_name": "Vijay"
},
"restaurentSetting": {
"restaurent_setting_id": "1",
"minimum_purcase": "200",
"payment_method_id": "1",
"title": "Best Hotel"
},
"zone": {
"zone_id": "1",
"by_zipcode": "1"
}
}]
}
and i want to fetch restaurentAddress and restaurentInfo
MY mainActivity.java file
package com.example.premi.jsonlist;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class MainActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView output = (TextView) findViewById(R.id.textView1);
String strJson="{\n" +
"\t\"status\": 1,\n" +
"\t\"data\": [{\n" +
"\t\t\"restaurent_id\": \"1\",\n" +
"\t\t\"user_id\": \"6\",\n" +
"\t\t\"zone_id\": \"1\",\n" +
"\t\t\"restaurentAddress\": {\n" +
"\t\t\t\"restaurent_address_id\": \"1\"\n" +
"\t\t},\n" +
"\t\t\"restaurentInfo\": {\n" +
"\t\t\t\"restaurent_info_id\": \"1\",\n" +
"\t\t\t\"restaurent_bussiness_owner_name\": \"Vijay\"\n" +
"\t\t},\n" +
"\t\t\"restaurentSetting\": {\n" +
"\t\t\t\"restaurent_setting_id\": \"1\",\n" +
"\t\t\t\"minimum_purcase\": \"200\",\n" +
"\t\t\t\"payment_method_id\": \"1\",\n" +
"\t\t\t\"title\": \"Best Hotel\"\n" +
"\t\t},\n" +
"\t\t\"zone\": {\n" +
"\t\t\t\"zone_id\": \"1\",\n" +
"\t\t\t\"by_zipcode\": \"1\"\n" +
"\t\t}\n" +
"\n" +
"\t}]\n" +
"}";
String dataoutput = "";
try {
JSONObject jsonRootObject = new JSONObject(strJson);
//Get the instance of JSONArray that contains JSONObjects
JSONObject status = jsonRootObject.optJSONObject("status");
JSONArray Dataarray =status.getJSONArray("data");
//Iterate the jsonArray and print the info of JSONObjects
for(int i=0; i < Dataarray.length(); i++){
JSONObject jsonObject = Dataarray.getJSONObject(i);
JSONObject Data = jsonObject.getJSONObject("restaurentAddress");
for(int j = 0 ; j < Data.length(); j++){
JSONObject GetData =Data.getJSONObject(String.valueOf(j));
int id = Integer.parseInt(GetData.getString("restaurent_address_id"));
String postcode = GetData.getString("postcode");
String addresss = GetData.getString("restaurent_address");
dataoutput += " : \n id= "+ id +" \n postcode= "+ postcode +" \n address= "+ addresss +" \n ";
}}
output.setText(dataoutput);
} catch (JSONException e) {e.printStackTrace();}
}
}

Try this out:
try {
JSONObject object = (JSONObject) new JSONTokener(YOUR_JSON_STRING).nextValue();
String restaurentAddressId = object.getJSONArray("data").getJSONObject(0).getJSONObject("restaurentAddress").getString("restaurent_address_id");
String restaurentInfoId = object.getJSONArray("data").getJSONObject(1).getJSONObject("restaurentInfo").getString("restaurent_info_id");
String restaurentBizOwnerName = object.getJSONArray("data").getJSONObject(1).getJSONObject("restaurentInfo").getString("restaurent_business_owner_name");
}
catch (JSONException e) {
}

Its Done I tried this
try {
JSONObject jsonRootObject = new JSONObject(strJson);
//Get the instance of JSONArray that contains JSONObjects
JSONArray mainnode =jsonRootObject.getJSONArray("data");
//Iterate the jsonArray and print the info of JSONObjects
for(int i=0; i < mainnode.length(); i++){
JSONObject jsonObject = mainnode.getJSONObject(i);
JSONObject Data = jsonObject.getJSONObject("restaurentInfo");
int id = Integer.parseInt(Data.getString("restaurent_info_id"));
String postcode = Data.getString("restaurent_phone_number");
String addresss = Data.getString("restaurent_bussiness_owner_name");
dataoutput += " : \n restaurent_id= "+ id +" \n restaurent_info_id= "+ postcode +" \n restaurent_address_id= "+ addresss +" \n ";
}
output.setText(dataoutput);
} catch (JSONException e) {e.printStackTrace();}
}
I just removed Status Object
and another for loop Thanks For the Help Got little Bit Help from You :)

sqlite constraint exception is thrown while parsing a json and storing it in db

Im trying to parse the following json
{
"status": 1,
"value": {
"shipment_master": {
"1": "Order Placed",
"2": "In Production",
"3": "Quality Check In progress",
"4": "Goods received for shipment",
"5": "Stuffing in progress",
"6": "Cargo Shipped"
}
}
}
Following is the code that I use to parse it..
JSONObject value = new JSONObject(notificationResponse.getString("value"));
JSONObject shipmentMaster = value.getJSONObject("shipment_master");
Iterator<String> shipmentMasterIterator = shipmentMaster.keys();
String status = null;
String key = null;
final int numberLenth = shipmentMaster.length();
while (shipmentMasterIterator.hasNext()) {
key = shipmentMasterIterator.next();
status = shipmentMaster.optString(key);
db.addShipmentMaster(new ShipmentMasterDao(Integer.valueOf(key), status));
}
Im getting the following error,
android.database.sqlite.SQLiteConstraintException: PRIMARY KEY must be unique (code 19)
Am I parsing the json correctly and adding it to the db properly?
This is my addShipmentMaster method
public void addShipmentMaster(ShipmentMasterDao shipmentMasterDao) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_ID, shipmentMasterDao.getId());
values.put(KEY_STATUS, shipmentMasterDao.getStatus());
db.insert(TABLE_SHIPMENTMASTER, null, values);
db.close();
}`

How to parse this structure of JSON Data?

I'd like to parse the following items from JSON data below: title, year, runtime, critics consensus, the theater release date, the synopsis, poster thumbnails, and poster originals. But when I parse my data I get a JSON Exception: No value for TAG_TITLE, and basically nothing happens.

This is the code for extracting the data I want:
jsonObject = new JSONObject(result);
JSONObject queryJSONObject = jsonObject.getJSONObject("query");
JSONObject resultsJSONObject = queryJSONObject.getJSONObject("results");
JSONArray moviesJSONArray = resultsJSONObject.getJSONArray("movies");
for(int i = 0; i < moviesJSONArray.length(); i++){
JSONObject c = moviesJSONArray.getJSONObject(i);
String title = c.getString("TAG_TITLE");
String year = c.getString("TAG_YEAR");
String mpaa_rating = c.getString("TAG_RATING");
String runtime = c.getString("TAG_RUNTIME");
String critics_consensus = c.getString("TAG_CONSENSUS");
JSONObject dates = c.getJSONObject("release_dates");
String theater = dates.getString("TAG_THEATER");
JSONObject posters = c.getJSONObject("posters");
String thumbnail_posters = posters.getString("TAG_TBPOSTER");
String original_posters = posters.getString("TAG_ORIPOSTER");
Log.e(TAG,

);
HashMap<String, String> movie = new HashMap<String, String>();
movie.put(TAG_TITLE, title);
movie.put(TAG_YEAR, year);
movie.put(TAG_RATING, mpaa_rating);
movie.put(TAG_RUNTIME, runtime);
movie.put(TAG_CONSENSUS, critics_consensus);
movie.put(TAG_THEATER, theater);
movie.put(TAG_TBPOSTER, thumbnail_posters);
movie.put(TAG_ORIPOSTER, original_posters);
moviesList.add(movie);
And before my OnCreate I'm using these Strings for the TAGS:
private static final String TAG_CONSENSUS = "critics_consensus";
private static final String TAG_RATING = "mpaa_rating";
private static final String TAG_YEAR = "year";
private static final String TAG_THEATER = "theater";
private static final String TAG_TITLE = "title";
private static final String TAG_RUNTIME = "runtime";
private static final String TAG_DATE = "theater";
private static final String TAG_TBPOSTER = "thumbnail_posters";
private static final String TAG_ORIPOSTER = "original_posters";
JSONArray movies = null;
ArrayList<HashMap<String, String>> moviesList;
My TAG_TITLE is "title" which is also used in the JSON Data so I'm at a loss as to why I get this error? Or is my code wrong? Thanks in advance

Shouldn't you do
String title = c.getString(TAG_TITLE);
instead of
String title = c.getString("TAG_TITLE");
?

You should have to either write String directly like
JSONObject jsonobject = new JSONObject(jsonString);
JSONObject queryjson = jsonobject.getJSONObject("query");
String count = queryjson.getString("count");
OR
//This Code is As per Your Coding
JSONObject jsonobject = new JSONObject(jsonString);
JSONObject queryjson = jsonobject.getJSONObject(TAG_QUERY);
String count = queryjson.getString(TAG_COUNT);
Inshort Just Remove The " " before Or After String Name TAG_..

How i replace java multiple chars and strings with others;

I have a string from http request and i want to replace multiple chars and strings with others.How i can do this?With Array for more efficient way?
String result =" "hourly": [ {"cloudcover": "0", "humidity": "93", "precipMM": "0.0", "pressure": "1013", "sigHeight_m": "0.7", "swellDir": "70", "swellHeight_m": "0.5", "swellPeriod_secs": "1.0", "tempC": "9", "tempF": "48", "time": "0", "v";
String result2 = result.replace("{", " ");
String result3 = result2.replace("}", " ");
String result4 = result3.replace("[", " ");
String result5 = result4.replace("]", " ");
String result6 = result5.replace("\"", "");
String result7 = result6.replaceAll("......", " ");
String result8 = result7.replaceAll("cloudcover", "\n \ncloudcover");
String result9 = result8.replaceAll("winddir:", " \nwinddir:");
String result10 = result9.replaceAll("tempC:", " \ntempC:");
WeatherInfos.setText( result10 );//Shows the weather info

Try following
String result = "{\"hourly\": [ {\"cloudcover\": \"15\", \"humidity\": \"93\", \"pressure\": \"1013\", \"tempC\": \"9\", \"winddir\": \"25\"}]}";
if(!result.startsWith("{"))
result = "{" + result + "}";
JSONObject JSONResult = new JSONObject(result);
JSONResult = (JSONObject) JSONResult.getJSONArray("hourly").get(0);
String cloudcover = JSONResult.getString("cloudcover");
String tempC= JSONResult.getString("tempC");
String winddir= JSONResult.getString("winddir"); //i do not see winddir in your result
Toast.makeText(getapplicationContext(), "Cloud Cover is "+ cloudcover , Toast.LENGTH_LONG).show();
now print cloudcover, winddir and tempC where ever you want.
