我正在尝试JSON Array用未知数据解析 a 。JSON像这样通过

{
    "info": [
        {
            "1": "4",
            "Store #": " 0560",
            "How many microwave circuits did you run?": " 3",
            "How many new ovens did you deliver to the store?": " 1",
            "How many new racks did you deliver to the store?": " 5",
            "Voltage readings on Turbo Chef 1": " 64",
            "Voltage readings on Turbo Chef 2": " 54",
            ...
        }
    ],
    "success": 1
}

现在因为在收到数据之前我不知道数据是什么，所以我不能使用传统的方法，比如

for (int i = 0; i < info.length(); i++) {

    JSONObject c = info.getJSONObject(i);

    String store = c.getString("Store #");
}

所以我正在尝试使用这种代码方法，但我没有成功

try {
    // Checking for SUCCESS TAG
    int success = json.getInt(TAG_SUCCESS);

    if (success == 1) {
        info = json.getJSONArray(TAG_INFO);
        for (int i = 0; i < info.length(); i++) {
            if (info != null) {                 
                    clientList.add(info.get(i).toString());                 
            }
        }
        for (String s : clientList) {
            Log.v("CHECKING S", s);
            s.split(":");
            Log.v("CHECKING S SPLIT", s);
            values.add(s);
            Log.v("CHECKING VALUES 0", values.get(0));
            mQuestions.add(values.get(0));
            Log.v("CHECKING VALUES 1", values.get(1));
            mAnswers.add(values.get(1));                        
        }

    }

然而，我的日志向我显示，不仅数据没有被拆分并放入ArrayLists我希望它保持JSON形式的状态。这是日志猫

那么我做错了什么？如果您需要更多代码询问，我会发布它。谢谢您的帮助

编辑

根据我收到的答案，我对代码进行了修改。现在看起来像这样

try {
// Checking for SUCCESS TAG
int success = json.getInt(TAG_SUCCESS);

if (success == 1) {
info = json.getJSONArray(TAG_INFO);
    for (int i = 0; i < info.length(); i++) {
        if (info != null) {             
            clientList.add(info.get(i).toString());             
        }
    }
    for (String s : clientList) {
        Log.v("CHECKING S", s);
        String[] str_arr= s.split("[:,]");                                              
        Log.v("CHECKING VALUES 0", str_arr[0]);
        mQuestions.add(str_arr[0]);
        Log.v("CHECKING VALUES 1", str_arr[1]);
    }
    for (String content : mQuestions) {
        Log.v("QUESTIONS", content);
    }

}

但是，正如logcat显示的那样，它现在只存储JSONmy的第一行ArrayLists

06-28 00:19:10.679: V/CHECKING VALUES 0(1724): {"Were any of the steamers gas?"
06-28 00:19:10.679: V/CHECKING VALUES 1(1724): " yes"
06-28 00:19:10.679: V/QUESTIONS(1724): {"Were any of the steamers gas?"

嗨，我已经为你做了这个。我只是在下面粘贴完整的代码。试试这种 json，它肯定对你有用。

我称该方法为：

String data = "{'info': [{'1': '4','Store #': ' 0560','How many microwave circuits did you run?': ' 3','How many new ovens did you deliver to the store?': ' 1','How many new racks did you deliver to the store?': ' 5','Voltage readings on Turbo Chef 1': ' 64','Voltage readings on Turbo Chef 2': ' 54'}],'success': 1}";

    try {
        JSONObject jsonData = new JSONObject(data);
        populateFromResponse(jsonData);

        } catch (JSONException e) {
            System.out.println(" Exception occured" + e.getMessage());
             e.printStackTrace();
        }
    }

现在 populateFromResponse() 方法的实现如下：

private static final String TAG_SUCCESS = "success"; private static final String TAG_INFO = "info"; private ArrayList<JSONObject> clientList; private ArrayList<String> mQuestions; private ArrayList<String> mAnswers;

  public void populateFromResponse(JSONObject json) throws JSONException {

    // parse the response   if (json != null) {

        // Checking for SUCCESS TAG         int success = json.getInt(TAG_SUCCESS);         // checking for null        if (success == 1) {             JSONArray info = json.getJSONArray(TAG_INFO);           if (info != null) {
                for (int i = 0; i < info.length(); i++) {
                    // checking for null
                    if (info.get(i) != null
                            && info.get(i) instanceof JSONObject)
                        if (clientList == null) {
                            clientList = new ArrayList<JSONObject>();
                        }
                    clientList.add(info.getJSONObject(i));
                }           }

            for (JSONObject s : clientList) {
                Log.v("CHECKING S", s.toString());
                // Iterator containing all the keys
                Iterator<String> iterator = s.keys();
                while (iterator.hasNext()) {
                    String key = (String) iterator.next();
                    String value = s.getString(key);

                    print("CHECKING VALUES 0: " + key);
                    // checking for null
                    if (mQuestions == null) {
                        mQuestions = new ArrayList<String>();
                    }
                    mQuestions.add(key);

                    print("CHECKING VALUES 1: " + value);
                    // checking for null
                    if (mAnswers == null) {
                        mAnswers = new ArrayList<String>();
                    }
                    mAnswers.add(value);
                }

                print("CHECKING S SPLIT: " + s);

            }       }   } else {        print("response is null");  }

}

private void print(String string) {     System.out.println("######-- " + string + " -----#########"); }

输出如下：

01-04 19:38:20.332: I/System.out(7685):

现在享受代码并快乐。再见。

您需要将s.split(":")结果分配给字符串数组：

for (String s : clientList) {
             Log.v("CHECKING S", s);
             String[] str_arr= s.split(":"); //<<<<<
             Log.v("CHECKING S SPLIT", str_arr);

             Log.v("CHECKING VALUES 0", str_arr[0]);
             mQuestions.add(str_arr[0]);
             Log.v("CHECKING VALUES 1", str_arr[1]);
             mAnswers.add(str_arr[1]);                        
        }
