使用SimpleDateFormat

是这样的:

event.putExtra("starttime", "12/18/2012");

SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy");
Date date = format.parse(bundle.getString("starttime"));

日期和时间格式说明

EEE : Day ( Mon )
MMMM : Full month name ( December ) // MMMM February   
MMM : Month in words ( Dec )
MM : Month ( 12 )
dd : Day in 2 chars ( 03 )
d: Day in 1 char (3)
HH : Hours ( 12 )
mm : Minutes ( 50 )
ss : Seconds ( 34 )
yyyy: Year ( 2020 ) //both yyyy and YYYY are same
YYYY: Year ( 2020 )
zzz : GMT+05:30
a : ( AM / PM )
aa : ( AM / PM )
aaa : ( AM / PM )
aaaa : ( AM / PM )

android Time类提供了3种格式化方法http://developer.android.com/reference/android/text/format/Time.html

我是这样做的:

/**
* This method will format the data from the android Time class (eg. myTime.setToNow())   into the format
* Date: dd.mm.yy Time: hh.mm.ss
*/
private String formatTime(String time)
{
    String fullTime= "";
    String[] sa = new String[2];

    if(time.length()>1)
    {
        Time t = new Time(Time.getCurrentTimezone());
        t.parse(time);
        // or t.setToNow();
        String formattedTime = t.format("%d.%m.%Y %H.%M.%S");
        int x = 0;

        for(String s : formattedTime.split("\\s",2))
        {   
            System.out.println("Value = " + s);
            sa[x] = s;
            x++;
        }
        fullTime = "Date: " + sa[0] + " Time: " + sa[1];
    }
    else{
        fullTime = "No time data";
    }
    return fullTime;
}

我希望这对你有帮助:-)

这段代码将返回当前日期和时间:

public String getCurrDate()
{
    String dt;
    Date cal = Calendar.getInstance().getTime();
    dt = cal.toLocaleString();
    return dt;
}

使用Time类中的构建!

Time time = new Time();
time.set(0, 0, 17, 4, 5, 1999);
Log.i("DateTime", time.format("%d.%m.%Y %H:%M:%S"));

Try:

event.putExtra("startTime", "10/05/2012");

当你访问传递的变量时:

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
Date date = formatter.parse(bundle.getString("startTime"));
