假設我的項目上有這段代碼。我想知道這個代碼有什麼問題。如果有人能幫助我，我會很高興。點擊here查看格式化的json字符串。JSONObject和JSONArray的問題

你面臨的問題是什麼> – Chandu

這個應用程序已經意外停止:( –

）我們不應該點擊看到字符串，你可以把它發佈在這裏嗎？ – brasofilo

在當前的JSON字符串 players

是JSONArray這裏面result JSONObject的，所以你需要先獲得result的JSONObject從主JSONObject然後從它那裏得到players JSONArray爲：

JSONObject result = new JSONObject(<JSON_STRING_HERE>); 
// get result JSONObject 
JSONObject jsonobj_result = result.optJSONObject("result"); 
// get players JSONArray 
JSONArray players = jsonobj_result.optJSONArray("players"); 
Player player; String data = null; 
for (int i = 0; i < players.length(); i++) { 
    player = new Player(players.getJSONObject(i)); 
    data += player.getFormattedHero(); 
}

JSON響應謝謝，這解決了我的問題 –

 JSONObject result; 
       URL url = new URL(
         ""); 
       URLConnection openConnection = url.openConnection(); 
       openConnection.connect(); 
       InputStream inputStream = openConnection.getInputStream(); 
       String inputStream2String = inputStream2String(inputStream); 
       result = new JSONObject(inputStream2String); 
       // here is my add code 
       // you can look the all names in the thi jsonObject 
       JSONArray names = result.names();// no hava players name in 
                // here; so 
       String string = result.getString("result"); 
       result = new JSONObject(string); 
       // my add code end 
       // look names again 
       names = result.names();// hava players name so get 
             // optJSONArray for players 
       JSONArray players = result.optJSONArray("players");// getData is ok

String data = null;

換成

StringBuffer data = new StringBuffer();

可能會更好。
