![](image/自定义View-验证码仿滴滴.gif) 4 | 5 | 6 | 7 | ### 实现思路 8 | 9 | **笔者这里决定继承RelativeLayout来实现自定义验证码的功能。显示验证码可以使用几个TextView，这里需要将TextView统一管理，所以还需要一个TextView数组。有光标，那自然而然的就想到了EditText，可以使用一个透明背景的EditText。几个验证码可以使用TextView以一定的规则进行排列，通过监听EditText的输入，拦截到输入字符，并将字符传递给TextView数组，并将EditText置为空，同时重设TextView选中状态，移动EditText光标。笔者这里采用给EditText设置paddingLeft的方式来实现光标的移动，当然，需要经过一些计算。OK，大概思路就是这样了，具体的代码我们继续看下面的。** 10 | 11 | ### 使用： 12 | 13 | ```xml 14 | 25 | ``` 26 | 27 | 28 | 29 | 效果参考上图 30 | 31 | 32 | 33 | 相关博客地址：[Android自定义View-仿滴滴自定义验证码输入框](https://riceeater.gitee.io/post/23-VerificationCodeView) 34 |
