資原始檔values下建立attrs檔案

<?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);//銀行卡號
phone.setContentType(0);//電話號
number.setContentType(2);//身份證號

獲取內容（去掉空格）

phone.getText().toString().replace(" ","");
