android - 更改计时器计划scheduleAtFixedRate

我有textview经常更新时间，这是正常的，但问题是，我想改变不同条件的时间表时间，但我无法改变时间表时间。它继续在最初设定的时间。

private Long mPeriod = Long.parseLong("8000");

public void startTimer() {
    Logger.i("startTimer", "startTimer");

    stopTimer();
    mTimer = new Timer();
    mTimerTask = new TimerTask() {
        @Override
        public void run() {
            // postInvalidate();
            Logger.i("timer", "timer");
            Thread th = new Thread(new Runnable() {

                @Override
                public void run() {
                    Logger.i("thread", "thread");

                    Long ll = System.currentTimeMillis();

                    mRelativeTime = DateUtils.getRelativeTimeSpanString(
                            Long.parseLong(mText + ""), ll, 0);

                    Long diff = ll - Long.parseLong(mText + "");
                    // long diffSeconds = diff / 1000 % 60;
                    long diffMinutes = diff / (60 * 1000) % 60;
                    long diffHours = diff / (60 * 60 * 1000) % 60;

                    Logger.d("diffMinutes", diffMinutes + "");
                    Logger.d("diffHours", diffHours + "");
                    if (diffMinutes == 0 && diffHours == 0) {
                        Logger.i("5000", "5000");
                        mPeriod = Long.parseLong("5000");
                    } else if (diffMinutes < 60 && diffMinutes != 0
                            && diffHours == 0) {
                        Logger.i("30000", "30000");
                        mPeriod = Long.parseLong("30000");
                    } else if (diffHours > 0) {
                        Logger.i("600000", "600000");
                        mPeriod = Long.parseLong("600000");
                    }
                    **// This line is not working...
                    mTimer.scheduleAtFixedRate(mTimerTask, 0, mPeriod);**
                    // Change text
                    handler.sendEmptyMessage(0);

                }
            });
            th.run();
        }
    };
    mTimer.scheduleAtFixedRate(mTimerTask, 0, mPeriod);
}

public void stopTimer() {

    if (mTimer != null) {
        mTimer.cancel();
        mTimer = null;
    }

}

最佳答案

您必须创建自己的customtimertask类，该类从timertask扩展而来。在此之后，您可以使用mcustomtimertask（customtimertask的对象）重新安排时间。Here是可能重复的答案。
