我在嘗試從JSON文件獲取信息時出現錯誤。我試圖從'post'中獲取數據,比如'NAME','YEAR'等,並將其打印到日誌中。它一直告訴我org.json.JSONException: No value for NAME
。有人能指引我朝着正確的方向嗎?JSON org.json.JSONException:「NAME」沒有值
JSON實例:
{"posts":[
{"post":{"ID":"74",
"TOURN_ID":"999",
"YEAR":"2016",
"START_DATE":"2016-09-07",
"END_DATE":"2016-09-18",
"DATE_STRING":"September 7th - 18th 2016",
"NAME":"2016 Paralympic Games",
"ShortName":"2016 Paralympic Games",
"TOURN_TYPE":"International"}},
{"post":{"ID":"73",
"TOURN_ID":"999",
"YEAR":"2016",
"START_DATE":"2016-06-23",
"END_DATE":"2016-06-25",
"DATE_STRING":"June 22nd - 23rd 2016",
"NAME":"2016 USABA National Goalball Championships",
"ShortName":"2016 US Nationals",
"TOURN_TYPE":"Domestic"}},
{"post":{"ID":"72",
"TOURN_ID":"999",
"YEAR":"2016",
"START_DATE":"2016-05-12",
"END_DATE":"2016-05-14",
"DATE_STRING":"May 12th-14th 2016",
"NAME":"2016 USABA Western Regional Goalball Tournament",
"ShortName":"2016 Utah",
"TOURN_TYPE":"Domestic"}}
]}
這裏是我的Java:
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
JSONObject jsonObject = new JSONObject(result);
String tournInfo = jsonObject.getString("posts");
Log.i("Tourn Info", tournInfo); // displays correctly
JSONArray arr = new JSONArray(tournInfo);
for(int i = 0; i < arr.length(); i++){
JSONObject jsonPart = arr.getJSONObject(i);
String name = jsonPart.optString("NAME");
Log.i("Each Tournament Object", jsonPart.getString("post"));// Work correctly displays all the 'post' items
這是我得到我的錯誤:
Log.i("Name of Tournament", jsonPart.getString("NAME"));
JSONArray ARR =新JSONArray(jsonObject.getJSONArray( 「上崗」));並刪除toudnInfo行.---編輯。對不起,它實際上是:JSONObject jsonPart = arr.getJSONObject(i).getJSONObject(「post」); – Guardanis
