推荐答案

这个问题已经被问和回答了SO多次。电话号码是（可能）存储在SIM卡上，您可以用得到它TelephonyManager.getLine1Number（）但是，它是不可靠的。有些SIM卡不具有对他们的电话号码（在这种情况下，你将获得空），如果用户不换他的SIM卡，然后改变了他的电话号码，你会得到他的旧电话号码。

This question has been asked and answered on SO a number of times. The phone number is (possibly) stored on the SIM-card and you can get it with TelephonyManager.getLine1Number() however, it is not reliable. Some SIM cards don't have the phone number on them (in which case you will get null) and if the user changes his phone number without swapping his SIM card then you will get his old phone number.
