问题 I am supplying the following regex : ^((?:\+27|27)|0)(\d{9})$ for number of South Africa and want to only return true for numbers that start with +27 or 27 or 0. eg; +27832227765, 27838776654 or 0612323434. I tried using: regexplanet.com and regex test But both return false no matter what I enter (even simple regex). Anybody know what I am doing wrong? 回答1: In Java code, you need to double the backslashes, and in a online tester, the backslashes must be single. Also, it is not necessary to

问题 In my app, the user has to enter a phone number in an EditText field using the following format: 1(515)555-5555 I don't want the user to type "(", ")", or "-" while entering the number; I want these characters to be added automatically.

I have tried to set text in the afterTextChanged method of

问题 I have a custom UITextField, which I am trying to 'format the input to phone number' as user types. What I want to achieve: Adding a prefixed + sign on the UITextField as the first character, that cannot be deleted. Format both the String variable and UITextField's text in the format of phone number nicely (+49 291 12345678) , rather than plain numbers (4929112345678) as user types in. I researched and found out that there is no built-in method for that. I've also found easy-to-use library

问题 I'm using the Paypal 'Express Checkout' option in Magento. (I'm not using any express checkout buttons, it's just because I was having problem with returning from Website Payments Standard). In Paypal's Website Payment Preferences, I've set the 'Contact Telephone Number' field to off.

问题 Goal: On the Android platform, detect the phone number of the individual with whom the user is speaking to now. Currently, using PhoneListener, there exists a certain ambiguity in the case of calls on hold. Case: User is talking to someone during a call ("Call 1"). The user is therefore in call state OFFHOOK. Then the user is in state RINGING indicating an incoming phone call ("Call 2"). The state then changes to OFFHOOK. This could indicate one of two possibilities -- either the user
