android：JSONArray类型的方法getJSONObject（int）不适用于参数（字符串）

我找不到我的错误。Eclipse告诉我：JSONArray类型的方法getJSONObject（int）不适用于我要访问的参数（字符串）：matchdata-> Goals-> Goal-> Goal_getter_name eclipse错误在这一行：`JSONObject Goal = openbuli.getJSONObject（“ goal”）; 我认为变量openbuli ist错误吗？我该如何解决？

这是我的代码：

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());
                        }

这是json数据：

$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
|    |    |    |    |    )
|    |    |    |    )
|    |    |    )
|    |    )

您需要更改openbuli.getJSONObject("goal");为openbuli.getJSONObject（0）;
并添加getJSONObject（“ goals”）以从数组的第一位获取对象目标

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());
                        }
