android json多維數組

Question

我有一個問題，以訪問多維數組中的json數據。 https://openligadb-json.heroku.com/api/matchdata_by_group_league_saison?group_order_id=20&league_saison=2010&league_shortcut=bl1

我的代碼適用於getJSONArray（「matchdata」）;

但我不能訪問matchdata-> match_results-> match_result [0] - > result_name

或

matchdata-> goals->目標[0] - > goal_getter_name

這裏我的代碼：

JSONObject json = null; 
      json = jsonFunctions.getJSONfromURL("http://openligadb-json.heroku.com/api/matchdata_by_group_league_saison?group_order_id="+ group_order_id +"&league_saison="+ league_saison +"&league_shortcut=" + league_shortcut);  
     if (json != null){ 

     try{ 
     JSONArray openbuli = null; 
     openbuli = json.getJSONArray("matchdata"); 
     mylist.clear(); 

      for(int i=0;i<openbuli.length();i++){      
       HashMap<String, String> map = new HashMap<String, String>();  
       JSONObject e = openbuli.getJSONObject(i); 



       map.put("id", String.valueOf(i)); 
       map.put("group_name", e.getString("group_name")); 
       map.put("name_team1", e.getString("name_team1")); 
       map.put("name_team2", e.getString("name_team2")); 
       map.put("points_team1", e.getString("points_team1")); 
       map.put("points_team2", e.getString("points_team2")); 
       map.put("halbzeit", e.getString("result_name")); 
       map.put("first", e.getString("name_team1") + " : " + e.getString("name_team2") + " " + points_team1 + " : " + points_team2); 
       map.put("second", e.getString("match_date_time")); 
       mylist.add(map); 
      }  
     } 

     catch(JSONException e){ 
     Log.e("log_tag", "Error parsing data "+e.toString()); 
     } 
     } 

我該如何訪問如： matchdata-> match_results-> match_result [0] - > result_name

這裏JSON數據：

$json (

| | ['0'] (
| | | league_name = "1. Fussball-Bundesliga 2010/2011"

Answer 1

我知道它應該在，而不是答案的評論，但我無法評論，由於聲譽，所以我我正在回答。

您可以使用gson庫來解析您的JSON響應。

請提供您的JSON響應，以便更容易理解。

Answer 2

private static String readMultidimensionalArray(JsonReader reader) throws IOException { 
    StringWriter sw = new StringWriter(); 
    JsonWriter jw = new JsonWriter(sw); 
    int arrayStack = 0; 
    do { 
     JsonToken t = reader.peek(); 
     switch (t) { 
      case BEGIN_ARRAY: 
       reader.beginArray(); 
       jw.beginArray(); 
       arrayStack++; 
       break; 
      case END_ARRAY: 
       reader.endArray(); 
       jw.endArray(); 
       arrayStack--; 
       break; 
      case NUMBER: 
       double d = reader.nextDouble(); 
       jw.value(d); 
       break; 
      default: 
       break; 
     } 

    } while (arrayStack != 0); 

    jw.flush(); 
    jw.close(); 
    return sw.toString(); 
} 

此代碼只是返回數組作爲json字符串，但它可以適應任何所需的邏輯。

示例輸出：[[1.0,0.9,0.0,0.0]，[0.9,0.8,0.0,0.0]，[0.0,0.0,0.3,0.5]，[0.0,0.0,0.5,0.7]]
