This is actually an answer from Mark Murphy:

对于大多数手机上，您使用的通知对象的号码字段。   看这里：    http://github.com/commonsguy/cw-android/tree/主/通知/ Notify1 /

For most phones, you use the number field of the Notification object. See here: http://github.com/commonsguy/cw-android/tree/master/Notifications/Notify1/

现在，有几部电话由一个主要的设备制造商有   一个bug，其中数场被忽略。我努力让   他们来修复它。所以你不能完全依赖于红色泡沫是   那里，虽然这将是在大多数手机上。

Now, there are a few phones by one major device manufacturer that have a bug, whereby the number field is ignored. I am working on getting them to fix it. So you can't absolutely rely on that red bubble being there, though it will be on most phones.
