JSON Array iteration in Android/Java

I am fetching JSON string from server and I have already got JSON string by code. But I didn't understand how to parse it.

Below is my JSON string

{ "university": { "name": "oxford", "url": "http://www.youtube.com" }, "1": { "id": "2", "title": "Baseball", "datetime": "2011-11-11 10:41:46" }, "2": { "id": "1", "title": "Two basketball team players earn all state honors", "datetime": "2011-11-11 10:40:57" } }

Please provide any guidance or code snippet.

Use JSON classes for parsing e.g

JSONObject mainObject = new JSONObject(Your_Sring_data); JSONObject uniObject = mainObject.getJSONObject("university"); String uniName = uniObject.getString("name"); String uniURL = uniObject.getString("url"); JSONObject oneObject = mainObject.getJSONObject("1"); String id = oneObject.getString("id"); ....

helloDroid Over a year ago

can we get how many objects in json string

Arslan Anwar Over a year ago

Yes you can simply use "mainObject.length();"

Edited to use getString() instead of getJSONObject() when getting String values. Using getJSONObject() caused a JSONException when I ran similar code that was fixed by using getString().

getString(), not getJsonString() as is written in the example, right?

Right @de. It should getString(), not getJsonString()

Below is the link which guide in parsing JSON string in android.

http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE

Also according to your json string code snippet must be something like this:-

JSONObject mainObject = new JSONObject(yourstring); JSONObject universityObject = mainObject.getJSONObject("university"); JSONString name = universityObject.getString("name"); JSONString url = universityObject.getString("url");

Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)

Same for other object.
