Question

我有一个问题是访问多维数组中的json数据。 https://openligadb-json.heroku.com/api/matchdata_by_group_league_saison?group_order_id=20&league_saison=2010&league_shortcut=bl1

我的代码适用于getJSONArray（“matchdata”）;

但我无法访问matchdata-＆gt; match_results-＆gt; match_result [0] - ＆gt; result_name

或

matchdata-＆GT; goals-＆GT;目标[0] - ＆GT; goal_getter_name

这是我的代码：

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());
      }
      }

我如何访问例如。 matchdata-＆GT; match_results-＆GT; match_result [0] - ＆GT; result_name

这里是json数据：

我知道它应该是评论而不是回答，但由于声誉我无法发表评论，所以我将其置于回答中。

您可以使用gson库来解析您的JSON回复。

请提供您的JSON回复，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();
}

此代码只是将数组作为json字符串返回，但它可以适应任何所需的逻辑。

示例输出：[[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]]
