我使用下列API来获取一个电话号码;然而，一些设备将在下面的格式返回数：

I am using following API to get a phone number; however, some of the device will return the number in following format:

++国家code +电话号码前。 12062436969

"+" + countrycode + phone number Ex. +12062436969

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
String phoneNumber = tm.getLine1Number();

我想找出路/算法，以消除这个+号和国家code，所以我将只得到最后的十位数。防爆。 12062436969 - > 2062436969

I would like to find out a way/algorithm to remove this "+" sign and the country code, so I will get only the last ten digits. Ex. +12062436969 -> 2062436969

我相信，我只需要最后的十位数。任何人都可以请提出任何想法？

I believe I only need the last ten digits. could anyone please suggest any idea?
