[英]How to Parse the JSON String Android
我正在嘗試解析下面的JSONString
[[{"0":"
","title":" Technical Support Analyst in Noida","1":"
","Company Name":" Oracle","2":"
","Category":"Fresher","3":"
","Job Type":"Full Time","4":"
","Location":"Noida","5":"
","Job Qualification":"BE\/BTch\/Bsc\/Others","6":"
","Job Experience":"Freshers","7":"
","Job postdate":"2013-6-05","8":"
"}]]
我的代碼:
// try parse the string to a JSON object
try {
//jObj = new JSONObject(JsonString);
JSONArray ja = new JSONArray(result);
int size = ja.length();
Log.d("tag", "No of Elements " + ja.length());
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
任何人都可以幫忙,我的守則不起作用? 我想解析標題,公司名稱,類別等...
你需要構建你的json。
沒有名為“result”的數組。 你要做的是用一個唯一的名稱命名json的每個元素,以便獲取它。
如
{"result":
["result1":["result2":{"0":"
","title":" Technical Support Analyst in Noida","1":"
","Company Name":" Oracle","2":"
","Category":"Fresher","3":"
","Job Type":"Full Time","4":"
","Location":"Noida","5":"
","Job Qualification":"BE\/BTch\/Bsc\/Others","6":"
","Job Experience":"Freshers","7":"
","Job postdate":"2013-6-05","8":"
"}]]}
您需要從jsonstring創建JSONArray
。
您在JSONArray
有JSONArray
,然后是JSONObect
..
try {
JSONArray ja = new JSONArray(buffer.toString());
JSONArray innerJsonArray = ja.getJsonArray(0);
JSONObject object = innerJsonArray.getJSONObject(0);
String title = object.getString("title");
}
catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
您可以嘗試下面的代碼來解析JSON
{
"result": "success",
"countryCodeList":
[
{"countryCode":"00","countryName":"World Wide"},
{"countryCode":"kr","countryName":"Korea, Republic of"},
{"countryCode":"us","countryName":"United States"},
{"countryCode":"jp","countryName":"Japan"},
{"countryCode":"cn","countryName":"China"},
{"countryCode":"in","countryName":"India"}
]
}
解析代碼
public static ArrayList<Country> ParseJson(String jsonstring) {
ArrayList<Country> arrCountries = new ArrayList<Country>();
String status;
String message = "";
try {
JSONObject json = new JSONObject(jsonstring);
status = json.getString("result");
if (status.equalsIgnoreCase("success")) {
JSONArray nameArray = json.names();
JSONArray valArray = json.toJSONArray(nameArray);
JSONArray valArray1 = valArray.getJSONArray(1);
valArray1.toString().replace("[", "");
valArray1.toString().replace("]", "");
int len = valArray1.length();
for (int i = 0; i < valArray1.length(); i++) {
Country country = new Country();
JSONObject arr = valArray1.getJSONObject(i);
country.setCountryCode(arr.getString("countryCode"));
country.setCountryName(arr.getString("countryName"));
arrCountries.add(country);
}
}
} catch (JSONException e) {
Log.e("JSON", "There was an error parsing the JSON", e);
}
return arrCountries;
}
