自己定义CountDownTimer

	class TimeCount extends CountDownTimer{

		public TimeCount(long millisInFuture, long countDownInterval) {

			super(millisInFuture, countDownInterval);

		}

		@Override

		public void onFinish() {

		}

		@Override

		public void onTick(long millisUntilFinished) {

			//计时显示

			if(millisUntilFinished/1000-1==0){

				//倒计时技术在handler中进行处理

			}

			tv_time.setText((millisUntilFinished/1000-1)+"s");//倒计时的时间显示

		}

	}

调用

	private TimeCount time;//计时器

	time=new TimeCount(60000,1000);//開始计时

	time.start();
