Question

我正在"restaurant_working_hours" = ( { close = { day = 1; dayName = Monday; time = 0000; }; open = { day = 1; dayName = Monday; time = 1500; }; }, { close = { day = 2; dayName = Tuesday; time = 0000; }; open = { day = 2; dayName = Tuesday; time = 1500; }; }, { close = { day = 3; dayName = Wednesday; time = 0000; }; open = { day = 3; dayName = Wednesday; time = 1500; }; }, { close = { day = 4; dayName = Thursday; time = 0000; }; open = { day = 4; dayName = Thursday; time = 1500; }; }, { close = { day = 5; dayName = Friday; time = 0000; }; open = { day = 5; dayName = Friday; time = 1500; }; } );工作，并从互联网上找到Android，如下所示：

json

我想找到JSONObject childObject=me.getJSONObject(pos); String fisrtkey=childObject.getString("A"); JSONArray jsonArray=childObject.getJSONArray("c");中的C21。请参阅来自请求的A。有人能帮助我吗？

Answer 1

您在解析时错过了 THIS json数组。首先从那个json对象得到它，然后得到 ME json数组。像这样的东西

    JSONObject j = new JSONObject(data);
    JSONArray c = j.getJSONArray("This");
    JSONObject j1 = c.getJSONArray(0);
    JSONArray d = j.getJSONArray("me");
    for(int n = 0; n < c.length(); n++) {
        JSONObject item = c.getJSONObject(n);
        System.out.println(item.getString("A"));
                    }

Answer 2

try {
        JSONObject j=new JSONObject(data);
        JSONArray c= null;
        c = j.getJSONArray("This");
        JSONObject item=c.getJSONObject(0);
        JSONArray me=item.getJSONArray("me");

        for(int pos=0;pos<me.length();pos++)
        {

            JSONObject childObject=me.getJSONObject(pos);
            String fisrtkey=childObject.getString("A");
            JSONArray jsonArray=childObject.getJSONArray("c");
        }



    } catch (JSONException e1) {
        e1.printStackTrace();
    }

//希望这对你有所帮助，并且检查json是否无效，你错过了 // jsonarray“我”的支架。

Answer 3

试试这个：

JSONObject j = new JSONObject(data);
JSONArray c = j.getJSONArray("me");
for(int n = 0; n < c.length(); n++) {
    JSONObject person = (JSONObject) c.get(n );
    String id = person.getString("A"); 
    ...
}

org.json.JSONException：从Json Object中查找特定字符串
