我已成功将日期字符串的格式从 yyyy-MM-dd
更改为 MM/dd
。现在的问题是,如果month
值和day
值分别小于 10,则格式应该是例如 2/7
而不是 02/07
.我该怎么做?
这是我的代码:
public static String cahngeFormat(String dateTime) {
Date date = null;
String str = dateTime;
DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
try {
date = formatter.parse(str);
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
calendar.add(Calendar.HOUR, 2);
formatter = new SimpleDateFormat("MM/dd");
str = formatter.format(calendar.getTime());
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
将格式从 "MM/dd"
更改为 "M/d"
以允许个位数输出。
formatter = new SimpleDateFormat("M/d");
DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
String timer = formatter.format(calendar.getTime());
formatter.setTimeZone(java.util.TimeZone.getTimeZone("GMT"));
txtTimerCount.setText(formatter.format(timePassed));
我希望这对你有用。
