Question

I am working on android. i am sending username and password using HttpPost and getting userid.

This is my code for my operation:

HttpClient hc = new DefaultHttpClient();

HttpPost post = new HttpPost("http://192.168.1.214/sample/dologin.php id="+strUID+ "&password="+strPass);

HttpResponse rp = hc.execute(post);

if (rp.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
    String userID = EntityUtils.toString(rp.getEntity());
    Log.v("Login response", "" + userID);
}

This is my output in DDMS

Login response(686): ([{"id":"5"}]);

But I need 5 as a result. So I can use this result in my next operations. Please tell me what should I do to extract 5 from the string ([{“id”:”5″}]);

Thank you in advance.

You can use JSON below is simple code..

StringBuffer sb = new StringBuffer(userID);
String s = sb.substring(sb.indexOf("["),sb.lastIndexOf("]")+1);
JSONArray ja = new JSONArray(s);
JSONObject jo = new JSONObject();
jo = (ja.getJSONObject(0));
String id = jo.getString("id");

Now you can use id variable..
