I want to get the name of school from this type of json :
"username": "blah",
"education": [
{
"school": {
"id": "[removed]",
"name": "[removed]"
},
"year": {
"id": "[removed]",
"name": "[removed]"
},
"type": "High School"
},
{
"school": {
"id": "[removed]",
"name": "[removed]"
},
"year": {
"id": "[removed]",
"name": "[removed]"
},
"type": "College"
}
]
here is my code :
JSONObject obj=null;
URL img_url;
String jsonUser = facebook.request("me");
obj=Util.parseJson(jsonUser);
String id=obj.optString("id");
String name=obj.optString("name");
what should i write the code to get the education fields school name ?
Facebook fb = new Facebook(API_KEY);// ... login user here ...JSONObject me = new JSONObject(fb.request("me")); String id = me.getString("id");
you can try
var schoolname = yourobject.education.school.name

I am trying to access value of 'cod' from the json string :
{"coord":{"lon":73.86,"lat":18.52},"sys":{"message":0.0293,"country":"IN","sunrise":1428972502,"sunset":1429017681},"weather":[{"id":801,"main":"Clouds","description":"few clouds","icon":"02d"}],"base":"stations","main":{"temp":304.301,"temp_min":304.301,"temp_max":304.301,"pressure":951.61,"sea_level":1021.56,"grnd_level":951.61,"humidity":36},"wind":{"speed":2.06,"deg":302.501},
"clouds":{"all":24},"dt":1428996633,"id":1259229,"name":"Pune","cod":200}
But I am not able to get this value from my code. the code I am using to access this value from json string is as:
try{
JSONObject jsObject=(new JSONObject(JsonString)).getJSONObject("coord");
if( jsObject.getInt("cod")==200) {
i.putExtra("jsn", JsonString);
i.putExtra("city", etCity.getText().toString());
startActivity(i);
}
In the if condition, you are trying to access the key "cod" in the array {"lon":73.86,"lat":18.52}. It will throw a JSONException.
Try this :
try{
JSONObject jsonmain = new JSONOBject(JsonString);
if(jsonmain.getInt("cod") == 200) {
i.putExtra("jsn", JsonString);
i.putExtra("city", etCity.getText().toString());
startActivity(i);
}
Your json is:
{
"coord": {
"lon": 73.86,
"lat": 18.52
},
"sys": {
"message": 0.0293,
"country": "IN",
"sunrise": 1428972502,
"sunset": 1429017681
},
"weather": [
{
"id": 801,
"main": "Clouds",
"description": "few clouds",
"icon": "02d"
}
],
"base": "stations",
"main": {
"temp": 304.301,
"temp_min": 304.301,
"temp_max": 304.301,
"pressure": 951.61,
"sea_level": 1021.56,
"grnd_level": 951.61,
"humidity": 36
},
"wind": {
"speed": 2.06,
"deg": 302.501
},
"clouds": {
"all": 24
},
"dt": 1428996633,
"id": 1259229,
"name": "Pune",
"cod": 200
}
The key "cod" is not nested inside "coord".
Try:
new JSONObject(JsonString)).getInt("cod");
Actually you are trying wrong JSON Object.
String cod=(new JSONObject(JsonString)).getJSONObject("code").toString();
//you may need to try catch block
if( Integer.parseint(cod)==200) {
.... Your logic
}
I am using volley in my app for network requests.I am trying to use GSON library for JSON parsing and create a list view with that.JSON looks like this.When I try to run the code I got an exception. What is wrong with this and what is missing

}
Supposing that you've this json into a jsonObject that you retrieve as response, this is the way:
// Get jsonArray 'education' from main jsonObject
JSONArray jsonArrayEducation = jsonObject.getJSONArray("education");
JSONObject jsonSchool = jsonArrayEducation.getJSONObject("school");
Note that if you are interested only at the name, you can group the two lines above into
JSONObject jsonSchool = jsonObject.getJSONArray("education").getJSONObject("school");
// get school name
String schoolName = jsonSchool.getString("name");
I decided I wanted to try using the Google shopping API out last week, but I had no idea how to parse JCON objects.
After much searching here I was able to get the product information for an item! However, I cannot narrow down to just a string in the product. So for example I want to just get the title of a product.
I have the following:
jsonString:
{
"kind": "shopping#products",
"etag": "\"GKsxsRlaBDslDpMe-MT1O7wqUDE/dMvQ5Pu2C806fWZJbNJ0GjdesJs\"",
"id": "tag:google.com,2010:shopping/products",

"startIndex": 1,
"itemsPerPage": 25,
"currentItemCount": 3,
"items": [
{

I have the following code in my android app to parse it:
try {
JSONObject jsonObject = new JSONObject(jsonString);
JSONArray itemsArray = jsonObject.getJSONArray("items");
JSONObject productObject = itemsArray.getJSONObject(0);
//String productTitle = productObject.getString("title");
//tv.setText(productTitle);
tv.setText(productObject.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
tv.setText("JSONOBJECT Error: " + e);
e.printStackTrace();
}
setContentView(tv);
The TextView on my Android app will now display (obviously not indented I did that for easy reading):
"product": {
"googleId": "9884865157760252836",
"author": {
"name": "Southeastern Delivery",
"accountId": "7585088"
},
"creationTime": "2011-07-25T00:15:58.000Z",

"brand": "Jif Peanut Butter",
"condition": "new",
"gtin": "00051500240908",
"gtins": [
"00051500240908"

}
],
"images": [
{
"link": "http://www.southeasterndelivery.com/images/ProductImages/00051500240908.jpg"
}
]
}
Now if you notice in my Java code I have two lines commented out. If I uncomment those lines and then comment the line:
tv.setText(productObject.toString());
tv gets set to this error: "JSONOBJECT Error: org.json.JSONEception: No value for title". I am not sure why this is true because clearly their is a title in the productObject.
Any help would be great!
I'm using json-smart in my project. It is very small and very fast. To convert your JSON from Sting to the actual object use JSONObjet json = (JSONObject)JSONValue.parse(rawString);
When you have JSONObject you treat it just like a Map. So String title = (String) json.get("title")
You are missing a level of information in your code. The JSON array contains items, which contains products, which have a title.
Your code should look like:
JSONObject jsonObject = new JSONObject(jsonString);
JSONArray itemsArray = jsonObject.getJSONArray("items");
JSONObject itemObject = itemsArray.getJSONObject(0);
JSONObject productObject = itemObject.getJSONObject("product");
String productTitle = productObject.getString("title");
I am getting the response

I can't change server code, so how do i parse it. any helped..
your enum:
enum CreditCardType{
Visa, MasterCard, Diners
}
and while parsing, when you reach till type
//param is JSONObject
CreditCardType card = CreditCardType.valueOf(param.getString("name"));
