Java 如何允许用户在Android中从联系人中选择一个或多个电话号码和/或电子邮件地址

我希望允许用户使用联系人选择器选择联系人，然后选择一个或多个电话号码和/或电子邮件地址，然后存储这些值

以下操作可用于获取多个电话号码：

Intent i = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);

对于多个电子邮件地址，请执行以下操作：

Intent i = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Email.CONTENT_URI);

但使用Contactables会使应用程序崩溃：

Intent i = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Contactables.CONTENT_URI);

---

我不一定要获取联系人的所有电话号码或所有电子邮件，我希望用户选择一个（或多个，如果可能）。

是这是可能的，选择联系人后，如果联系人有多个电话号码，会弹出一个对话框。此代码由Howetti提供：。确保将此权限添加到您的清单中
