Java：将字符串格式化为电话号码 [英] Java: Format a string as a telephone number

问题描述

我有一个未格式化的电话号码字符串（5551234567）。我想在ui中格式化此字符串以用于显示目的。格式后数字应如下所示：

I have an unformatted telephone number string ("5551234567"). I would like to format this string for display purposes in the ui. The number should look like this after format:

[phone]

[phone]

叹气...... 。

我试图找到一种考虑美国和国际电话号码的通用方法。我来自JDK中的MaskFormatter，但发现Javadoc中存在一个错误。这引导我在这里问我的问题。我希望有一个解决方案，我可以输入一个掩码，然后输入实际的字符串。对于国际/美国号码，输出将相应地格式化，或者如果指定了错误的字符数，则将显示一些默认字符来代替丢失的字符........

I was trying to find a generic way that would take into account both US and international phone numbers. I came accross the MaskFormatter in the JDK but discovered that there is a bug in the Javadoc. Which lead me to asking my question here. I was hoping for a solution where I could input a mask then the actual string. The output would be formatted accordingly for international/US numbers or if the wrong number of characters were specified, some default character would be displayed in place of the missing characters........
