android：JSONArray類型的getJSONObject（int）方法不適用於參數（字符串）

Question

我沒有找到我的錯誤。 Eclipse告訴我：JSONArray類型中的方法getJSONObject（int）不適用於參數（字符串） 我想訪問：matchdata - > goals - > goal - > goal_getter_name eclipse錯誤在這一行上：`JSONObject goal = openbuli.getJSONObject（「goal」）; 我認爲變量openbuli ist錯了？！ 我該如何解決它？

這裏北京時間我的代碼：

String result = ""; 
SONObject jArray = null; 

jArray = new JSONObject(result); 

       JSONObject json = (JSONObject) jArray;     
       JSONArray openbuli = json.getJSONArray("matchdata"); 

       JSONObject goal = openbuli.getJSONObject("goal"); 
       JSONArray goals = goal.getJSONArray("goals");   

       // loop array 
       for(int i=0;i<goals.length();i++) {  
           JSONObject e = goals.getJSONObject(i); 
           Log.e("Name", e.getString("goal_getter_name").toString()); 
         } 

這裏JSON數據：

$json (
| matchdata => Array (9) 
| (
| | ['0'] (
| | | league_saison = "2013" 
| | | match_results (
| | | | match_result => Array (2) 
| | | | (
| | | | | ['0'] (
| | | | | | result_name = "Endergebnis" 
| | | | | | result_order_id = "1" 
| | | | | | points_team1 = "3" 
| | | | | | result_type_name = "nach 90 Minuten" 
| | | | | | points_team2 = "1" 
| | | | | | result_type_id = "2" 
| | | | | ) 
| | | | ) 
| | | ) 
| | | goals (
| | | | goal => Array (4) 
| | | | (
| | | | | ['0'] (
| | | | | | goal_match_minute = "16" 
| | | | | | goal_getter_id = "5112" 
| | | | | | goal_id = "21118" 
| | | | | | goal_getter_name = "Mario Mandzukic" 
| | | | | | goal_mach_id = "23711" 
| | | | | | goal_penalty = FALSE 
| | | | | | goal_score_team1 = "2" 
| | | | | | goal_own_goal = FALSE 
| | | | | | goal_score_team2 = "0" 
| | | | | | goal_overtime = FALSE 
| | | | | ) 
| | | | ) 
| | | ) 
| | ) 

Answer 1

您需要更改openbuli.getJSONObject("goal");到openbuli.getJSONObject（0）;
並添加getJSONObject（「目標」），以獲得從首位的目標對象數組

String result = ""; 
SONObject jArray = null; 

jArray = new JSONObject(result); 

       JSONObject json = (JSONObject) jArray;     
       JSONArray openbuli = json.getJSONArray("matchdata"); 

       JSONObject goal = openbuli.getJSONObject(0); 
       JSONArray goals = goal.getJSONObject("goals").getJSONArray("goal");   

       // loop array 
       for(int i=0;i<goals.length();i++) {  
           JSONObject e = goals.getJSONObject(i); 
           Log.e("Name", e.getString("goal_getter_name").toString()); 
         }
