为电话号码格式化EditText视图 [英] Format EditText view for phone numbers

问题描述

我有一个EditText视图，我希望它将用户的输入格式化为电话号码格式。例如，当用户输入1234567890时，只要前3个数字输入，EditText视图应该动态显示为（123）456-7890。

我在我的OnCreate中尝试了以下内容，但它似乎没有为我做任何事情...

  EditText ET =（ EditText）findViewById（R.id.add_number）; 
 ET.addTextChangedListener（new PhoneNumberFormattingTextWatcher（））; 
  

如何让用户的输入以电话号码格式显示？

解决方案

我做了一些事情的组合，我修改我的输入类型为手机，然后我用正则表达式来删除所有非数字字符：phonenumber = phonenumber.replaceAll （\D，）;

I have an EditText view and I want it to format the user's input into the phone number format. For example, when the user types in 1234567890, the EditText view should dynamically show it as "[phone]" as soon as the first 3 numbers are inputted.

I tried the following in my OnCreate but it didn't seem to do anything for me...

EditText ET = (EditText) findViewById(R.id.add_number);
ET.addTextChangedListener(new PhoneNumberFormattingTextWatcher());

How can I get the user's input to display in the phone number format?

解决方案

I did a combination of things, i modified my input type to phone, then I used regex to remove all non numeric characters: phonenumber = phonenumber.replaceAll("\D", "");
