Question

I have a JSON string like this of data for a table in an android app. one of {} is a row of data for the table. I want to separate these {}s into an array and then each element inside this array into other sub-arrays separating other elements inside {}. Please suggest an appropriate way of accomplishing this criteria using JSON. Thank you.

[
     {
        "nodeName":"prime_mtsc22@smpp3",
        "nodeId":"MTSC3",
        "tidPrefix":"4",
        "optStatus":"offline",
        "daStart":"1",
        "daEnd":"3",
        "description":"Description"
     },
     {
        "nodeName":"prime_mtsc22@smpp2",
        "nodeId":"MTSC58",
        "tidPrefix":"1",
        "optStatus":"blocked",
        "daStart":"5",
        "daEnd":"10",
        "description":"new description"
     },
     {
        "nodeName":"prime_mtsc22@smpp1",
        "nodeId":"MTSC1",
        "tidPrefix":"15",
        "optStatus":"online",
        "daStart":"12",
        "daEnd":"20",
        "description":"Description"
     },
     {
        "nodeName":"prime_mtsc22@smpp0",
        "nodeId":"MTSC15",
        "tidPrefix":"15",
        "optStatus":"offline",
        "daStart":"25",
        "daEnd":"30",
        "description":"Description"
     }

Answer 1

ok so in that case the code to use is this

String jsonString = <your jsonString>;

// THIS IS NOT NEEDED ANYMORE 
//JSONObject json = new JSONObject(jsonString);

JSONArray topArray = null; 
try {
     // Getting your top array

     // THIS IS NOT NEEDED ANYMORE 
     //topArray = json.getJSONArray(jsonString);

     //use this instead
     topArray = new JSONArray(jsonString);

      // looping through All elements
      for(int i = 0; i < topArray.length(); i++){
      JSONObject c = topArray.getJSONObject(i);

      //list holding row data
      List<NodePOJO> nodeList = new ArrayList<NodePOJO>(); 

      // Storing each json item in variable
      String nodeName = c.getString("nodeName");
      String nodeID = c.getString("nodeID");

      NodePOJO pojo = new NodePOJO();
      pojo.setNodeName(nodeName);
      //add rest of the json data to NodePOJO class

      //the object to list
      nodeList.add(pojo);

    }
} catch (JSONException e) {
        e.printStackTrace();
 }

ok?
