Split your items using \\|.

Example :

String items= "1333333454510|-7611868|-7222457" ; //here you got items

String[] _items=items.split("\\|");

Now iterate loop and convert it into long using Long.ParseLong().

EDIT :

As Ashwin said you need to use json.getString("items"); to get items.

You can convert it into long using following code.

ArrayList<Long> longs=new ArrayList<Long>();


for(int i=0;i<_items.length;i++){
longs.add(Long.parseLong(_items[i]));
}

@Pheonix7 As Ashwin mention in his code. use json.getString().

Use Split function to separate.

parse json to get items in items String

use jsonObject.getString instead of jsonObject.getJSONObject to avoid error.

String items= "1333333454510|-7611868|-7222457" ; 
String[] itemsArray =items.split("\\|");

String response= "{"status":0,"items":"1333333454510|-7611868|-7222457"}" ; // ie, response contains the string.

JsonObject json= new JsonObject(response);

String item=json.getString("items");
String [] items =item.split("|");

Will get 3 numbers in the items array.

json object should be like this. {"status":0,"items":"1333333454510|-7611868|-7222457"}

JsonObject json= new JsonObject(response);

String item=json.getString("items");
String [] items =item.split("|");

your problem is here

  JSONObject obj = JSONParser.getJSONFromUrl(URL + "search", parameters);
  String firstItem = obj.getJSONObject("items").toString();

so change it to

String firstItem = obj.getString("items").toString();

and then do split operations as suggested by others.

SO force always with you:)
