android 計時器，倒計時

自定義CountDownTimer

	/**
	 * 計時器
	 * @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) {
			//計時顯示
			if(millisUntilFinished/1000-1==0){

				//倒計時技術在handler中進行處理
				
			}
			
			tv_time.setText((millisUntilFinished/1000-1)+"s");//倒計時的時間顯示
			
		}
		
	}

調用

	private TimeCount time;//計時器		
	time=new TimeCount(60000,1000);//開始計時
	time.start();
