錯誤獲取JSON數據

Question

你好這是我的JSON數據

{"CategoryID":1,"CategoryName":"Clothing","Status":true,"SubCategoryList": [{"Status":true,"SubCategoryID":1,"SubCategoryName":"Male"}, {"Status":true,"SubCategoryID":2,"SubCategoryName":"Female"}, {"Status":true,"SubCategoryID":3,"SubCategoryName":"Kids"}, {"Status":true,"SubCategoryID":4,"SubCategoryName":"New Born Baby"}, {"Status":true,"SubCategoryID":11,"SubCategoryName":"Sun Glasses"}]}, {"CategoryID":2,"CategoryName":"Alcohol","Status":true,"SubCategoryList": [{"Status":true,"SubCategoryID":5,"SubCategoryName":"Wine"}, {"Status":true,"SubCategoryID":6,"SubCategoryName":"Beer"}, {"Status":true,"SubCategoryID":7,"SubCategoryName":"Scotch"}]}, {"CategoryID":3,"CategoryName":"Restourents","Status":false,"SubCategoryList": [{"Status":true,"SubCategoryID":8,"SubCategoryName":"Breakfast"}, {"Status":true,"SubCategoryID":9,"SubCategoryName":"Tour Package"}]}] 

我的代碼：

JSONArray collection = new JSONArray(json1); 
int length = collection.length(); 
for(int i=0;i<length;i++){ 
JSONObject row = collection.getJSONObject(i); 
String value = row.getString("CategoryName"); 
String value6 = row.getString("SubCategoryName"); 
} 

得到了值類別名稱：服裝，酒類，Restourents。
無法獲取SubCategoryName的值。
解析數據時出錯org.json.JSONException：SubCategoryName沒有值
如何獲取SubCategoryName的數據。

Answer 1

SubCategoryName是SubCategoryList jsonArray內

JsonArray arr = row.getJsonArray("SubCategoryList"); 
arr.getJsonObject[0].getString("SubCategoryName");
