How to parse this JSON Array in android? [duplicate]

Sending and Parsing JSON in Android

EDIT: Finally I found an answer to get array value without key value by using Iterator. I just got an idea from this link

I am just newbie to JSON Parsing, and I have no idea how to parse this kinda JSONArray. Can anyone give me a hint ?

{

 "pages": [
      "image1.jpg",
      "image2.jpg"
  ]
}

Doesn't JSON.parse work in android? that's an array inside an object by the way. — user1726343

You have to understand the basic concepts of JSON .

{} talks about an instance (called JSONObject) [] talks about an array of somethings (called JSONArray in Android) "xxx":"yyy" talks about key & value

First, you may let the reply json string become an JSONObject, JSONObject replyJSON = new JSONObject(reply)

Then, get the JSONArray named 'pages' inside the replied JSONObject, JSONArray pagesArray = replyJSON.getJSONArray("pages")

Finally, get the value inside the JSONArray by the method getString, in your example, you may use pagesArray.getString(0) and pagesArray.getString(1)

Check out the documentation for more details: JSONArray

thanks for your info. is it possible to get all the datas from pages array without using pagesArray.getString(0)nor (1) ?

you may get the length of the JSONArray by using .length() and iterate though the JSONArray :)

Use new JSONObject(json); where json is the variable that stores your json string.

Use the JQuery function parseJSON:

var json = jQuery.parseJSON(string);

The asker asked how to do it in android

I believe, the OP is requesting how to parse JSON in Java on Android. Not in a browser and not using jQuery.
