Android 倒计时CountDownTimer

image.png

美工妹子给的图如下,订单在创建时间的24小时后进行关闭

业务逻辑

从后台返回来的订单创建时间加24小时后减去你当下的时间
就是相差的总共时间,然后进行倒计时
倒计时结束后上传订单关闭标识,改变状态页

实现思路

可能在没有遇到CountDownTimer之前,我们都是创建Handle来开启异步线程来处理,如果你现在使用,我只能说太菜了,官方已经为我们封装好了一个类,爽的很,一起来看

 @Override
    public void initData() {
        countDownTimer = new CountDownTimer(time, 1000) {
            @Override
            public void onTick(long millisUntilFinished) {
                if (!TestActivity.this.isFinishing()) {

                    long day = millisUntilFinished / (1000 * 24 * 60 * 60); //单位天

                    long hour = (millisUntilFinished - day * (1000 * 24 * 60 * 60)) / (1000 * 60 * 60);
                    //单位时
                    long minute = (millisUntilFinished - day * (1000 * 24 * 60 * 60) - hour * (1000 * 60 * 60)) / (1000 * 60);
                    //单位分
                    long second = (millisUntilFinished - day * (1000 * 24 * 60 * 60) - hour * (1000 * 60 * 60) - minute * (1000 * 60)) / 1000;
                    //单位秒
                    textView.setText(hour + "小时" + minute + "分钟" + second + "秒");
                }
            }

            /**
             *倒计时结束后调用的
             */
            @Override
            public void onFinish() {

            }

        };
        countDownTimer.start();
    }

传了两个参数,第一个参数就是时间的总值,换算成毫秒值,第二个代表以毫秒来计算

两个方法:
onTick :倒计时执行的方法
onFinsh:倒计时结束后的方法
countDownTimer.start(); 开始倒计时

就是这么简单,但是两个坑,来看下

• 空指针问题

在某些场景下，CountDownTimer 会导致空指针 如果在Activity或者Fragment被回收时并未调用CountDownTimer的cancel()方法结束自己，这个时候CountDownTimer的Handler方法中如果判断到当前的时间未走完，那么会继续调用onTick方法，Activity或者Fragment已经被系统回收，从而里面的变量被设置为Null，同时，CountDownTimer中的Handler方法还在继续执行，这一块空间始终无法被系统回收也就造成了内存泄漏。
*在CountDownTimer的onTick方法中记得对当前对象做判空处理
*#####可能造成内存泄漏问题

 * 记得关闭,负责内存溢出
 */
@Override
protected void onDestroy() {
    super.onDestroy();
    if (countDownTimer != null) {
        countDownTimer.cancel();
        countDownTimer = null;
    }
}
