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(" ", "");
