资源文件values下创建attrs文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
 
 <declare-styleable name="contentwithspaceedittext">
  <attr name="input_type" format="enum">
   <enum name="phone" value="0"/>
   <enum name="bank_card_no" value="1"/>
   <enum name="identify_card_no" value="2"/>
  </attr>
 </declare-styleable>
 
</resources>

使用

bank.setcontenttype(1);//银行卡号
phone.setcontenttype(0);//电话号
number.setcontenttype(2);//身份证号

获取内容（去掉空格）

phone.gettext().tostring().replace(" ", "");
