android 计时器，记时

自定义CountDownTimer

	/**	 * 计时器	 * @author Administrator	 *	 */	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);//开始计时	time.start();
