我一直在使用以下代码来创建列表视图：

public class AndroidJSONParsingActivity extends ListActivity {


// url to make request
private static String url = "http://api.androidhive.info/contacts/";

// JSON Node names
private static final String TAG_CONTACTS = "contacts";
private static final String TAG_ID = "id";
private static final String TAG_NAME = "name";
private static final String TAG_EMAIL = "email";
private static final String TAG_ADDRESS = "address";
private static final String TAG_GENDER = "gender";
private static final String TAG_PHONE = "phone";
private static final String TAG_PHONE_MOBILE = "mobile";
private static final String TAG_PHONE_HOME = "home";
private static final String TAG_PHONE_OFFICE = "office";

上面这个有效，但如果我把它改成：

private static String url = "http://kondicioner.al/app/json.php";

    // JSON Node names
    private static final String TAG_CONTACTS = "contacts";
    private static final String TAG_ID = "id";
    private static final String TAG_NAME = "emer";
    private static final String TAG_EMAIL = "mbiemer";
    private static final String TAG_ADDRESS = "telefon";
    private static final String TAG_GENDER = "adresa";
    private static final String TAG_PHONE = "ora";
    private static final String TAG_PHONE_MOBILE = "per";
    private static final String TAG_PHONE_HOME = "dyqan";
    private static final String TAG_PHONE_OFFICE = "statusi";

它现在不起作用。我不明白可能是什么问题，它应该起作用，同样的结构同样的东西......谢谢

JSON 结构不同。

这是第一个结构的样子（为简洁起见，我只保留了一条记录）：

{
   "contacts":[
      {
         "id":"c200",
         "name":"Ravi Tamada",
         "email":"ravi@gmail.com",
         "address":"xx-xx-xxxx,x - street, x - country",
         "gender":"male",
         "phone":{
            "mobile":"+91 0000000000",
            "home":"00 000000",
            "office":"00 000000"
         }
      }
   ]
}

这就是第二个结构的样子：

{
   "contacts":[
      {
         "id":"12",
         "emer":"Albana",
         "mbiemer":"",
         "telefon":"",
         "adresa":"",
         "ora":"10:13:44",
         "per":"",
         "dyqan":"",
         "statusi":"",
         "orari_transportit":"",
         "data":"15\/4\/2013"
      }
   ]
}

两种情况下JSON的结构是不同的。在工作情况下，您有

"phone": {
                    "mobile": "+91 0000000000",
                    "home": "00 000000",
                    "office": "00 000000"
                }

而在第二种情况下（您的非工作代码）没有等效的子标签。因此，当您使用第一个 JSON 的代码解析第二个 JSON 时，您的代码应该会因解析错误而失败。
