【Android】Json 資料處理

如果 Json 資料如下：

{
    "status": 200,
    "message": "取得系統靜態文字資料成功！",
    "table_info": [
        {
            "question_type_code": "01",
            "type_name": "詢問使用方式"
        },
        {
            "question_type_code": "02",
            "type_name": "問題回報"
        },
        {
            "question_type_code": "03",
            "type_name": "建議"
        },
        {
            "question_type_code": "99",
            "type_name": "其他"
        }
    ]
}


處理 function 可以這麼寫

private void JsonProcess(String responseJson) {

    JSONObject response;
    try {

        response = new JSONObject(responseJson);
        String status = response.getString("status");
        System.out.println(TAG + "status:" + status);
        if (status.equals("200")) {


            String message = response.getString("message");

            
            System.out.println(TAG + "message:" + message);


            JSONArray tableInfoList = response.getJSONArray("table_info");
            for (int i = 0; i < tableInfoList.length(); i++) {

               String tableInfoJson = tableInfoList.getString(i);
               System.out.println("tableInfoJson:" + tableInfoJson);
               JSONObject tableInfoContent = new JSONObject(tableInfoJson);
String questionTypeCode = tableInfoContent.getString("question_type_code");
String typeName = tableInfoContent.getString("type_name");
System.out.println(TAG + "questionTypeCode i [" + i + "]:" + questionTypeCode);
System.out.println(TAG + "typeName i [" + i + "]:" + typeName);

            }


        } else {

            String error = response.getString("error");

        }

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


}
