关于CountDownButton倒计时控件的一些问题

[cllstudy]

问题描述:
在布局文件中使用CountDownButton控件,在代码中设置改控件的监听,需求是这样的,点击CountDownButton弹出一个底部对话框,此时不进行倒计时,弹出对话框后需要输入图形验证码上的数字,验证通过后开始倒计时.我试过setEnableCountDown方法都无济于事,而startCountDown()方法开启倒计时确是私有的,请问我该如何实现呢

自己重写了一个,建议CountDownButton开放startCountDown方法

看你的描述，我建议你使用CountDownButtonHelper,这样更灵活些
