我有一个Java的倒计时你自己稍微改一下就行了
是每隔15分钟就开始倒计时的



public String getTimeFalse() {

		Calendar calendar = Calendar.getInstance();

		String falseTime = null;

		Date date = new Date();

		//calendar.setTime(date);

		int minute = (14-calendar.getTime().getMinutes()%15);

		//System.out.println(minute);

		int second = (60-calendar.getTime().getSeconds());

		//System.out.println(second);

		int hour = 0;



		String seconds = "";

		String minutes = "";

		String hours = "";



		//while (minute * second >= 0) {



			if (second < 10) {

				seconds = "0";

			} else {

				seconds = "";

			}

			if (minute < 10) {

				minutes = "0";

			} else {

				minutes = "";

			}

			if (hour < 10) {

				hours = "0";

			} else {

				hours = "";

			}

			falseTime = hours + hour + ":" + minutes + minute + ":" + seconds

					+ second;

			//System.out.println(falseTime);



			if (second != 0) {

				second--;

			} else {

				second = 59;

				if (minute > 0) {

					minute--;

				} else {

					minute = 0;

				}

			}

		return falseTime;

	}
