【问题描述】：
我正在尝试访问模拟器中所有联系人的联系人详细信息。我得到了访问其他详细信息所需的解决方案。访问电话和电子邮件类型时出现问题。我使用下面的代码来获取电话类型和电子邮件类型。应用程序正在运行，没有编译错误。

问题是，我在 ListView 中得到了不正确顺序的电话类型和电子邮件类型。这意味着我将 2 个号码 [Home, Mobile] 和 2 个电子邮件 [Home, Work] 保存到特定联系人。当我运行代码时，此联系人的 ListView 显示变为对于数字 [Mobile, Work] 和电子邮件 [Mobile, Work]。我无法更正代码。如何使 ListView 正确显示。有人知道如何调试吗？
【问题讨论】：
-
我不明白....数字不正确吗？是否显示工作号码的手机号码？或者它们是否正确，而您只是希望它们以不同的顺序显示？
-
实际上显示包括5个详细信息... Name, NumberType, Number, EmailTYPE, Email...表示号码类型表示个人号码或家庭号码或手机...电子邮件类型也是像这样......它的顺序不正确......这是我保存了 2 个号码和 2 封电子邮件以联系 KARTHIK 的图像---第一个号码类型是家庭，第二个号码类型是手机，第一个电子邮件类型是家庭和 2 个工作，但是它显示为手机和电子邮件的移动和工作（tinypic.com/view.php?pic=2eydeli&s=6）

发布您的适配器代码，它可能在那里。还要检查您的数据...如果它在其他地方工作但不适用于此联系人，则很有可能您在创建此联系人时将信息保存为错误的类型（或者在我看来）。

我编辑代码并粘贴它。请检查它
