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(" ", "");
