很多时候需要手机号进行注册，并且需要对手机号码归属于那个运营商做一下判断。先来说一下思路：首先，需要获取到用户输入的手机号码，然后将目前三大运营商运营的手机号码前缀分别组成list数组，然后截取用户手机号码前缀，看归属于哪个list，这样就用到了上一篇文章说的list.contains()方法了。下面来看一下例子
代码语言：javascript复制 public String getMobileType(String mobile) {
if (mobile.startsWith("0") || mobile.startsWith(" 860")) {
mobile = mobile.substring(mobile.indexOf("0") 1, mobile.length());
}
List chinaUnicom = Arrays.asList(new String[] { "130", "131", "132",
"145","155", "156", "186", "185" });
List chinaMobile1 = Arrays.asList(new String[] { "135", "136", "137",
"138", "139", "147","150", "151", "152", "157", "158", "159", "182","187",
"188" });
List chinaMobile2 = Arrays.asList(new String[] { "1340", "1341",
"1342", "1343", "1344", "1345", "1346", "1347", "1348" });
boolean bolChinaUnicom = (chinaUnicom.contains(mobile.substring(0, 3)));
boolean bolChinaMobile1 = (chinaMobile1
.contains(mobile.substring(0, 3)));
boolean bolChinaMobile2 = (chinaMobile2
.contains(mobile.substring(0, 4)));
if (bolChinaUnicom)
return "1";//联通
if (bolChinaMobile1 || bolChinaMobile2)
return "2"; //移动
return "3"; //其他为电信
}
