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

Question

我想让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。

以下适用于获取多个电话号码：

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

以下是多个电子邮件地址：

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）。

是的，这是可能的，选择一个联系人后，如果该联系人有多个电话号码，则会弹出一个对话框。此代码由 Howetti:Selecting a number from user with multiple numbers when using the contact picker 提供。确保将此权限添加到您的清单
