如何解析android中的json响应

Question

can some parse the json encode response from php into java arraylist. My string is

[{"Link_Id":"811"},{"Link_Id":"1389"},{"Link_Id":"6190"}]

what I tried is

static JSONObject jObj = null;
JSONArray link_Ids = null;
ArrayList<Integer> ids;
jObj = new JSONObject(a);
link_Ids = jObj.getJSONArray("Link_Id");
for (int i = 0; i < link_Ids.length(); i++) {  // **line 2**
     JSONObject childJSONObject = link_Ids.getJSONObject(i);
     ids.add(childJSONObject.getString(i));
}

can some one please correct me

Answer 1

the string represents a json array so it should be like this:

link_Ids = new JSONArray(a);
for (int i = 0; i < link_Ids.length(); i++) {  
   JSONObject childJSONObject = link_Ids.getJSONObject(i);
   ids.add(childJSONObject.getString("Link_Id"));
}
