Answer 1

Follow this for JSON Parsing...

I create sample code for your JSON data.. Check and let me know is it working?

String jsonData = your_data;
ArrayList<String> mListID;
ArrayList<String> mListTitle;

try {
JSONObject jsonOBJ = new JSONObject(jsonData);

// Getting JSON Array node
JSONArray mArrayID  =  jsonObj.getJSONArray("ID");
mListID = new ArrayList<String>();

for(int i=0 ; i<mArrayId.length(); i++)
{
    mListID.add(mArrayId.get(i))
}
JSONArray mArrayTitle  =  jsonObj.getJSONArray("Title");
mListTitle = new ArrayList<String>();
for(int j=0 ; j<mArrayTitle.length(); j++)
{
    mListTitle.add(mArrayTitle.get(j))
}
} catch (JSONException e) {
   e.printStackTrace();
}

Answer 2

Try this:

  //your json String
  String jsonStr;

  if (jsonStr != null) {
        try {
        JSONObject jsonObj = new JSONObject(jsonStr);

        // Getting JSON Array node
        JSONArray data  =  jsonObj.getJSONArray("ID");

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

You should read some tutorials and documentation on json parsing in android from here , here and here .

  You can implement it like this :



    List id;
    List title;
    String jsonTxt = inputStream;
    JSONObject jsonObj = new JSONObject(jsonTxt);
    JSONArray jsonArray1 = jsonObj.optJSONArray("Id");
    JSONArray jsonArray2 = jsonObj.optJSONArray("Title");
    if (jsonArray1.length() > 0) {
    id=new ArrayList();
    for (int index = 0; index < jsonArray1.length(); index++) {
    JSONObject sellerObj = jsonArray1.optJSONObject(index);
    id.add(sellerObj.optString("name"));//name of ids 
    }
   }

saee as Title or other array.

Answer 4

firstly you parse you server response

json jsonResponse = new json(response);

JSONArray id[] = jsonResponse.getJSONArray("Id");

JSONArray title = jsonResponse.getJSONArray("Title");

JSONArray description[] = jsonResponse.getJSONArray("Description");

JSONArray newsUpdatedDateTime[] = jsonResponse.getJSONArray("NewsUpdatedDateTime");

JSONArray imageUrl[] = jsonResponse.getJSONArray("ImageUrl");

String lastUpdateTime =  jsonResponse.getString("LastUpdatedTime");

String responseMessage =  jsonResponse.getString("ResponseMessage");

String responseCode =  jsonResponse.getString("ResponseCode");

//==========================================================================//

Then you can parse remain your single array:

    for (int i = 0; i < id.length(); i++) {  // **line 2**
     String name = id.get(i);
    }

I think it will help.
