How do I parse JSON in Android? [duplicate]

Closed 5 years ago.
I am new to android development. I am stuck try to show dropdown's data into android . Data will come from server as a json format. I am using volley library for HTTP requests. Here is my volley response
{"blood_group_map":[{"value":"1","text":"O+"},{"value":"2","text":"O-"},{"value":"3","text":"A+"},{"value":"4","text":"A-"},{"value":"5","text":"B+"},{"value":"6","text":"B-"},{"value":"7","text":"AB+"},{"value":"8","text":"AB-"}]}
In this response I want draw blood_group_map key in Spinner option list like this HTML. Here value key is used for value and text key is used for display text.
<option value="1">O+</option>
Update:
I parsed this JSON but I want to send spiner value property to server and display text property. How can I send value to server not text ?
For Example if I select O+ blood group then I send spinner value 1 to server.


Use GSON parser to parse data to from json.
Basic working of GSON is: you build an object with structure same as your json.
All you have to do is pass it to spinner. An example of GSON parser here: GSON parser example

Display json string result in listview in android

How to display JSON string result in Android ListView
Here is the JSON string
[{"USER_ID":83,"PROJECT_BY_DETAILS":"An adaptation of a nursery rhyme into a dramatic film"},{"USER_ID":88,"PROJECT_BY_DETAILS":"Test - over ye mountain blue "}]
I need to display USER_ID and PROJECT_BY_DETAILS in a ListView

if you got this json from server - you can use retrofit for parsing information into object.
or you can use default android classes for parsing
http://developer.android.com/reference/org/json/package-summary.html
parse this json to arraylist of objects, and create listview adapter

Create a Model to save your json Data

Decode json response in android

I need to decode a json response sent from php in android.
JSON Response
{"VehicleNumber":"1234FB14","Make":"BMW","Model":"X5","Type":"Car","Color":"Black","EngineCapacity":"1800cc","Fuel":"Diesel","DateOfReg":"31-Dec-2013","OwnerNIC":"B1234567890123","serviceArray":[[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1800","Description":"tponggshmbch"}],[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1900","Description":"tponggshmbch"}]]}
The response consists of values for their respective keys and I can retrieve these value by just calling getString(key) in java. {key:value,2D Array[][]}
The problem is that I can't decode the 2D Array being passed here. I get it in a string format in java and if I display it in my android app I can view this:
[[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1800","Description":"tponggshmbch"}],[{"VehicleNumber":"1234FB14","DateOfService":"07-march-2014","Mileage":"1900","Description":"tponggshmbch"}]]
But i need to retrieve all the value from the 2D array.
Any help please.

If Your json is quite big I recommend using gson or Jackson libraries.

how to extract web text in android like rss to display it on android GUI?

how to extract some criteria from this page http://www.zigwheels.com/api/zigtvApi.php?method=data&module=News&section=News
and filter this ( content_id , thumbnail, summary , headline , image) to display them as rss feeds in my android GUI

The output from that URL looks like a JSON feed. You can easily parse JSON data in Android using the JsonObject - see this tutorial for a comprehensive example.
A better (and probably easier) solution would be to use Google Gson and extract the object that way. I've written a full (compilable) program you can use as an example here.

You are receiving a JSONArray from that page. You should create some objects from that JSONArray which will be later displayed in a ListView. For retrieving objects from that feed you could use Json or Gson as #Marvin Pinto suggested, or you could also have a look at my ObjectFactory project, which is a very simple and easy to use parser. It can simply create your objects from a json or xml feed, and you could also use it asynchronously.
After you fetch your objects, with your desired option, you can create a ListAdapter and use it to display your objects in your ListView.

Well, this looks like JSON, so use a JSON-Parser, for a tutorial see here. You can make your JSON more readable (especially when asking on SO) using the JSON beautifier
