Zmagania z jsonem

[matixd3]

Mam taki kod w pliku .json:

 

[
{
"type":"home",
"number":"(800) 111-1111"
},
{
"type":"cell",
"number":"(800) 222-2222"
}
]

Wycinek kodu java:

 

 

JSONArray jsonMainArr = new JSONArray(json);
            for (int i = 0; i < jsonMainArr.length(); i++) {  // **line 2**
                JSONObject childJSONObject = jsonMainArr.getJSONObject(i);
                String name = childJSONObject.getString("type");
                String age     = childJSONObject.getString("number");
                System.out.print(name + "     " + age);
            }

json to String z całym tekstem o zawartości:

[{"type":"home","number":"(800) 111-1111"},{"type":"cell","number":"(800) 222-2222"}]

 

błąd:

Już nie mam siły do tego :/

[AdirasOwns]

Spróbuj tego:

{

[{

"type":"home",

"number":"(800) 111-1111"}

},

{

"type":"cell",

"number":"(800) 222-2222"

}]

}

 

 

[Gość]

LOL to żeś rozjebał system. Jakim cudem żeś tak to pokiepcił.

Dzięki tobie uświadomilem sobie gdzie jest błąd

 

Teraz inny problem:

dodałem:

            json = "[\n" +
" {\n" +
"\"type\":\"home\",\n" +
"\"number\":\"(800) 111-1111\"\n" +
"},\n" +
"{\n" +
"\"type\":\"cell\",\n" +
"\"number\":\"(800) 222-2222\"\n" +
"}\n" +
]";

I teraz wszystko dziala więc wina leży po stronie pobierania treści pliku do zmiennej

 

 

Mój kod:

            url = new URL(a);
            URLConnection conn = url.openConnection();

            // open the stream and put it into BufferedReader
            BufferedReader br = new BufferedReader(
                               new InputStreamReader(conn.getInputStream()));

            String inputLine;
            String json = "";
            while ((inputLine = br.readLine()) != null) {
                    json += inputLine;
            }
            br.close();

W zmiennej a jest link do pliku .json na stronie www

 

 

 

 

 

 

 

 

 

 

EDIT

 

Działa

Dla innych zmieniłem pobieranie z internetu na to:

in = new URL( "link" ).openStream();
                json = IOUtils.toString( in, "UTF-8");

i zapisałem z takim samym kodowaniem
