Android通过一个long值（秒数）返回格式化日期样式

/**
* 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;
