The org.json library is easy to use.
Just remember (while casting or using methods like getJSONObject
and getJSONArray
) that in JSON notation
[ … ]
represents an array, so library will parse it toJSONArray
{ … }
represents an object, so library will parse it toJSONObject
Example code below:
import org.json.*;
String jsonString = ... ; //assign your JSON String here
JSONObject obj = new JSONObject(jsonString);
String pageName = obj.getJSONObject("pageInfo").getString("pageName");
JSONArray arr = obj.getJSONArray("posts"); // notice that `"posts": [...]`
for (int i = 0; i < arr.length(); i++)
{
String post_id = arr.getJSONObject(i).getString("post_id");
......
}
