Android下定时任务

方法一：

Timer timer;

TimeTask task;

timer.schedule(task, delay, period);

方法二：

/**

*@ parm  millisInFuture  间隔多少秒

*@ parm countDownInterval 多久后执行

**/

     CountDownTimer cdt = new CountDownTimer(long millisInFuture, long countDownInterval) {

//倒计时
@Override
public void onTick(long millisUntilFinished) {
System.out.println("millisUntilFinished"+millisUntilFinished);

}

@Override
public void onFinish() {
System.out.println("finish");

}
};
cdt.start();
