电子邮件未从 Android 通讯录中显示

Question

我正在从设备的通讯录中获取联系人。我在获取电子邮件时遇到问题。我试过了，它一直显示电话号码或号码（我猜它是一种类型）。请帮忙。

这是我的 AdressBook.java

如果此问题得到解决，我将不胜感激。谢谢

您正在尝试从您的 phoneCursor 字段中获取电子邮件，您将其初始化如下：

phoneCursor = getActivity().getContentResolver().query(Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");

Phone.CONTENT_URI 表只包含电话号码相关信息，不包含任何电子邮件。

如果您需要不止一种类型的数据，您应该查询CommonDataKinds.Data.CONTENT_URI，它应该返回所有类型的联系信息，您可以使用selection将其限制为电话和电子邮件：

Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "' OR " + Data.MIMETYPE + "='" + Email.CONTENT_ITEM_TYPE + "'"
