使用 JSONArrays：如何转换为 ArrayList<String[]>

Question

我有 json 如下所示

{  
   "tiles":[  
      {  
         "header":"Manual",
         "subheader":"Login",
         "summary1_label":"",
         "summary2_label":"",
         "summary3_label":"",
         "summary4_label":"",
         "summary1_value":"",
         "summary2_value":"",
         "summary3_value":"",
         "summary4_value":"",
         "iconUrl":"http://x.x.x.x\/icon1.png"
      },
      {  
         "header":"NewUser",
         "subheader":"Login",
         "summary1_label":"",
         "summary2_label":"",
         "summary3_label":"",
         "summary4_label":"",
         "summary1_value":"",
         "summary2_value":"",
         "summary3_value":"",
         "summary4_value":"",
         "iconUrl":"http://x.x.x.x.x\/icon2.png"
      },
      {  
         "header":"Facebook",
         "subheader":"Login",
         "summary1_label":"",
         "summary2_label":"",
         "summary3_label":"",
         "summary4_label":"",
         "summary1_value":"",
         "summary2_value":"",
         "summary3_value":"",
         "summary4_value":"",
         "iconUrl":"http://x.x.x.x/icon3.png"
      }
   ]
}

我将其转换为 JsonObject 并将其发送到重新格式化方法。在那个方法中我做了以下

public ArrayList<String[]> formatHttpResponse_SummaryTile(JSONObject json) throws JSONException {
    ArrayList<String[]> arrayList_summary = new ArrayList<String[]>();
    JSONArray tilesArray = json.getJSONArray("tiles");
    //JSONObject allTilesData = json.getJSONObject("tiles");
    for (int i=0; i<tilesArray.length(); i++)
    {
        //JSONObject thisJsonObject = tilesArray.getJSONObject(i);
        JSONArray thisJsonArray = tilesArray.getJSONArray(i);
        String[] thisStringArray = new String[thisJsonArray.length()];
        for (int j=0; j<thisJsonArray.length(); j++)
        {
            thisStringArray[j]=thisJsonArray.getString(j);
        }
        arrayList_summary.add(thisStringArray);
    }
    return arrayList_summary;
}

如您所见，我创建了一个数组列表，然后循环遍历我的 jsonObjects 3 children。现在的问题是我想将 children 转换为 String[][ 但我的代码在 JSONArray thisJsonArray = tilesArray.getJSONArray(i); 处出错，因为它不是 json 数组。

知道如何将上面的 children 放入 3 个字符串数组中，所有字符串数组都添加到 arrayList 中吗？我可以做更有效的直接转换吗？

public ArrayList<String[]> formatHttpResponse_SummaryTile(JSONObject json) throws JSONException {
            JSONObject thisJsonObject = tilesArray.getJSONObject(i); //create jsonObject to grab values from
            Iterator<String> iter = thisJsonObject.keys();
            String[] thisStringArray = new String[thisJsonObject.length()];
            int count=0; //track which element we are on in the dest string[]
            while (iter.hasNext())
            {
                String key = iter.next();
                try
                {
                    String value = (String)thisJsonObject.get(key);
                    thisStringArray[count] = value;
                }
                catch (JSONException e) {
                    // Something went wrong!
                    break;
                }
                count++;
            }
            arrayList_summary.add(thisStringArray);
}

return arrayList_summary;
}
