Android通過一個long值（秒數）返回格式化日期樣式

/**
 * 返回的字符串形式是形如：2013-10-20 20:58
 * */
public static String formatTimeInMillis(long timeInMillis) {
	Calendar cal = Calendar.getInstance();
	cal.setTimeInMillis(timeInMillis);
	Date date = cal.getTime();
	SimpleDateFormat dateFormat = new SimpleDateFormat(
			"yyyy-MM-dd HH:mm:ss");
	String fmt = dateFormat.format(date);

	return fmt;
