CountDownTimer的使用

//倒计时时间是60000ms，每1000ms执行一次onTick

onTick的参数是剩余的倒计时时间

countDownTimer=new CountDownTimer(60000,1000) {

@Override
public void onTick(long millisUntilFinished) {
daojishi.setOnClickListener(null);
daojishi.setText(millisUntilFinished/1000+"秒后可重发");
}
@Override
public void onFinish() {
daojishi.setOnClickListener(MainActivity.this);
daojishi.setText("获取验证码");
}

};

countDownTimer.start();//开始倒计时

countDownTimer.cancle();//结束倒计时
