The regular expression functions written based on these expressions are as follows:

1 public static boolean isMobileNO(String mobiles) {2         String telRegex = "13\\d{9}|14[57]\\d{8}|15[012356789]\\d{8}|18[01256789]\\d{8}|17[0678]\\d{8}";3         if (TextUtils.isEmpty(mobiles)) return false;4         else return mobiles.matches(telRegex);5     }

Where:

"13 \ d {9}" indicates that the first two digits are 1 and 3, followed by any 9 digits;

"14 [57] \ d {8}" indicates that the first two digits are 1 and 4, the third digit is 5 or 7, and the last two digits are any 8 digits;

And so on.

 

• License plate number

The Regular Expression of the license plate number has been available on the Internet and has not been changed:

1 public static boolean isCarnumberNO (String carnumber) {2/* 3 license plate number format: Chinese Character + A-Z + 5-digit A-Z or 0-94 (only including general license plate number, license plate numbers for coaches and some military vehicles are not included) 5 */6 String carnumRegex = "[\ u4e00-\ u9fa5] {1} [A-Z] {1} [A-Z_0-9] {5}"; 7 if (TextUtils. isEmpty (carnumber) return false; 8 else return carnumber. matches (carnumRegex); 9}

Of course, this regular expression has limitations. For example, the first character can only be Chinese characters, but only 34 Chinese characters can be abbreviated. The license plate number does not contain letters I and O, which prevents confusion with 1 and 0; some license plates cannot be distinguished.
