我正在尝试使用未知数据解析JSON Array。 JSON就像这样来了
{
"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
}
现在因为我不知道数据会在收到之前是什么，所以我不能使用像
这样的传统方法for (int i = 0; i < info.length(); i++) {
JSONObject c = info.getJSONObject(i);
String store = c.getString("Store #");
}
所以我试图使用这种代码方法而且我不成功
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，我的日志告诉我，不仅数据没有被分割并放入ArrayLists，因为我希望它保持在JSON形式。这是logcat

那么我做错了什么？如果您需要更多代码询问，我会发布。谢谢你的帮助
修改
根据我收到的答案，我对代码进行了修订。它现在看起来像这样
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);
}
}
然而，现在只在我JSON ArrayLists中存储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?"
的第一行，因为logcat显示
{{1}}

您好我已经为您做了这件事。我只是粘贴下面的完整代码。尝试使用这种json，它一定会对你有用。
我将该方法称为：
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 + " -----#########"); }
输出为：
01-04 19:38:20.332: I/System.out(7685):

现在享受代码并开心。 再见。
答案 1 :(得分：1)
您需要将s.split(":")结果分配给String Array：
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]);
}
