Convert JSONObject to JSONArray

Question

i am using this JSONParser.java:

public class JSONParser {
 static InputStream is = null;
 static JSONObject jObj = null;
 static String json = "";
 // constructor
 public JSONParser() {
 }
 public JSONObject getJSONFromUrl(String url, List<NameValuePair> params) {
 // Making HTTP request
 try {
 // defaultHttpClient
 DefaultHttpClient httpClient = new DefaultHttpClient();
 HttpPost httpPost = new HttpPost(url);
 httpPost.setEntity(new UrlEncodedFormEntity(params));
 HttpResponse httpResponse = httpClient.execute(httpPost);
 HttpEntity httpEntity = httpResponse.getEntity();
 is = httpEntity.getContent();
 } catch (UnsupportedEncodingException e) {
 e.printStackTrace();
 } catch (ClientProtocolException e) {
 e.printStackTrace();
 } catch (IOException e) {
 e.printStackTrace();
 }
 try {
 BufferedReader reader = new BufferedReader(new InputStreamReader(
 is, "iso-8859-1"), 8);
 StringBuilder sb = new StringBuilder();
 String line = null;
 while ((line = reader.readLine()) != null) {
 sb.append(line + "\n");
 }
 is.close();
 json = sb.toString();
 Log.e("JSON", json);
 } catch (Exception e) {
 Log.e("Buffer Error", "Error converting result " + e.toString());
 }
 // try parse the string to a JSON object
 try {
 jObj = new JSONObject(json); 
 } catch (JSONException e) {
 Log.e("JSON Parser", "Error parsing data " + e.toString());
 }
 // return JSON String
 return jObj;
 }
}

it is working fine for my other requests. Now my php-file sending an array. How I convert it to an Jarray or directly in an ArrayList, which i can use in my app?

the array (2 items) looks like:

03-15 20:40:16.667: E/JSON(26100): [{"ean":"8029694000","name":"KRINGS-VERBAU","betriebsdatenalt":"412"},{"ean":"8026786937","name":"KOMPRESSOR FAHR 5,3 M3 XAS97DDG","betriebsdatenalt":"0"}]

• stkent: Have you looked at developer.android.com/reference/org/json/JSONArray.html ?
• beresfordt: As an aside I'd seriously reccomend looking at gson or jackson for dealing with json; the org.json library is not the most pleasant to work with

Answer 1

If you have an array

 JSONArray myArray=new JSONArray(string)

now loop through the array and get the objects like

 ArrayList<JSONObject> yourObjects=new ArrayList<JSONObject>(); 
 for(int i=0;i<myArray.length();i++){
 yourObjects.add(myArray.getJSONObject(i))
 }

also check every time if its a object or array you are getting like if

 JSONObject obj=new JSONObject(string from server);
 if(obj==null){
 JSONArray array=new JSONArray(string from server)
 }
