Android实现自定义验证码输入框效果(实例代码)

这里提一下，这个当时也是在网上看到一个博主写的代码改了下用在我么项目中的验证码输入框。博主的地址不记得了这里只能顺带标注一下。。。

效果图如下：

就是这个酱紫

直入主题，代码如下：

}

 主要有两种显示样式，在枚举中定义了4个输入框6个输入框

基本调用代码如下：

//ll_sms_input就是CustomSmsCodeInputLayout
ll_sms_input.run {
//里边的配置可以自行选择配置
   setTopTipVisible(false)
   setCurrentCenterLineVisible(true)
   setBottomSmsTvVisible(true)
   setShowInputNum(CustomSmsCodeInputLayout.InputLineNum.SIX)//这里加载的是六个输入框
   setCurrentIndexLineColor(resources.getColor(R.color.global_text_color_grey))
   //设置输入类型只能是数字
   setInputType(InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_SIGNED)
   showSoftInput()
  }
ll_sms_input.setOnInputListener()//做输入完成后的监听
ll_sms_input.setOnClickSmsCodeTvListener()//点击重新获取按钮的监听
