为什么联系人 ID 在 PhoneLookup 和 ContactsContract.Contacts 选择器之间不匹配？

Question

我的应用正在扫描 SMS 消息并计算指标，然后将其存储在数据库中，该数据库由与 SMS 上的 phone 号码相关联的联系人 ID 键控。使用 PhoneLookup 机制查找第一个联系人 ID。稍后我还让用户 select 使用联系人选择器意图联系。但即使是同一个人 selected，从选择器返回的联系人 ID 也不同于通过 PhoneLookup 获得的联系人 ID。这是为什么？

这里有一个 activity 显示了这种效果。将 PHONE_NUMBER 设置为您 phone 上已知联系人的 phone 号码。然后点击 "Pick Contact" 按钮和 select 相同的联系人。对我来说，这两种方法的联系人 ID 是不同的。

Answer 1

此代码：

val pickContactIntent = Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI)
pickContactIntent.type = ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE

return CommonDataKinds.Phone._ID 不是 Contacts._ID

为什么联系人 ID 在 PhoneLookup 和 ContactsContract.Contacts 选择器之间不匹配？

Why do contact IDs not match between PhoneLookup and the ContactsContract.Contacts picker?
