I need value of v which is 1. I'm getting this
{"v":"1"}
through
JSONObject r2 = new JSONObject(operation);
String title = r2.getString("title");
System.out.println(title);
How do I get the value of v after this? It would be great if I could get any suggestions.
The value of title is a string with JSON text, so you need to re-invoke the JSON parser.
Also, in the question code, you forgot to navigate past the data node.
JSONObject rootObj = new JSONObject(operation); // parse JSON text
String title = rootObj.getJSONObject("data").getString("title"); // get "title" value
JSONObject titleObj = new JSONObject(title); // parse JSON text
String v = titleObj.getString("v"); // get "v" value
System.out.println(v); // prints: 1
String v= r2.getJSONObject("title").getString("v");
System.out.println(v);
PS: Don't forget to handle nulls,etc.
UPDATE: Please refer Andreas's answer as it is the correct answer. This answer wrongly assumes that title also contains json.
title is not a JSON object, but a string. The string content just happens to be another JSON text.
getString on r2 object which is of type JSONObject which is same as in the answer I have provided.title is not a JSON object, and this answer doesn't work, for the reason I already stated. Don't know why it has been upvoted. See here for working solution.
