上面代码是工具类，
使用方法，
1，初始化工具类
countDownMsgUtils = new CountDownMsgUtils.Builder(this)
.setDefaultColor("#fc8952")
.setChangeColor("#CACACA")
.setBtnTextview(mBtnCode)//获取验证码的控件
.setTime(60).setSaveTimeKey("register_time").build();
2，开始获取验证码
在点击获取验证码控件的时候调用以下方法
countDownMsgUtils.requestCheckCode(new CountDownMsgUtils.ICountDownPostCode() {
@Override
public void allowToRequestCode() {
//调用接口获取验证码
getYourCode();
}
});
3，获取验证码成功，开始倒计时
这个代码是获取验证码吗成功的回调
countDownMsgUtils.requestSuccess();//获取短信成功开始倒计时
4，资源回收
@Override
public void onDestroy() {
super.onDestroy();
countDownMsgUtils.clossHandler();
}
