Question

所以我有一个Jsonobject作为我服务器的响应，格式如下：

{"SubjectName":["Irish"],"BookName":["Bun Go Barr 1"]}{"WorksheetID":[5],"WorksheetName":["TESTS"]}

通常为了获得结果，我只需按照以下方式在对象内的特定数组中进行基本循环：

try {
            jsonArray = jsonObject.getJSONArray("SubjectName");
        } catch (JSONException e) {
            e.printStackTrace();
        }
        BookSubject = new String[jsonArray.length()];
        for (int i = 0; i < jsonArray.length(); i++) {
            try {
                BookSubject[i] = jsonArray.getString(i);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

然而，似乎在这种情况下有一个额外的“{”分隔一些数组意味着当我尝试为工作表ID执行此操作时，我在logcat中得到以下内容：

任何人都知道我怎么能把它拿起来？

Answer 1

您的json无效。

您可以测试json在线工具http://www.jsoneditoronline.org/

更改表格：

{"SubjectName":["Irish"],"BookName":["Bun Go Barr 1"]}{"WorksheetID":[5],"WorksheetName":["TESTS"]}

致：

[
  {
    "SubjectName": "Irish",
    "BookName": "Bun Go Barr 1"
  },
  {
    "WorksheetID": 5,
    "WorksheetName": "TESTS"
  }
]
