How to use regular expression to judge mobile phone number and license plate number in Android, aiming at this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

The 170 code segment of the third-party operator

Add: Unicom 4G 176, China Telecom 4G 177, Mobile 4G 178

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

Public static boolean isMobileNO (String mobiles) {String telRegex = "\\ d {} | []\ d {}"; if (TextUtils.isEmpty (mobiles)) return false; else return mobiles.matches (telRegex);}

Where:

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

"14 [57]\ d {8}" means that the first two digits are 1 and 4, the third is 5 or 7, followed by any 8 digits.

and so on.

License plate number

The regular expression of the license plate number has been online all the time, but it hasn't changed much:

Public static boolean isCarnumberNO (String carnumber) {/ * license plate number format: Chinese character + Amurz + bit Amurz or-(only ordinary license plate numbers, trainer cars and some army vehicles are not included) * / String carnumRegex = "[\ ue-\ ufa] {} [Amurz] {} [Amurz -] {}"; if (TextUtils.isEmpty (carnumber)) return false Else return carnumber.matches (carnumRegex);}

Of course, this regular expression has limitations, such as the first bit is only limited to Chinese characters, there are only 34 provincial Chinese character abbreviations; the license plate number does not have the letters I and O, to prevent confusion with 1, 0; some license plates can not be distinguished, and so on.
