Android 日期时间格式,android,android-dialogfragment,android-datepicker,android-timepicker,Android,Android Dialogfragment,Android Datepicker,Android Timepicker,我在datepicker中选择日期，得到的是edittext:13/12/2014但我必须这样显示：13 Dec 2014 public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener { public EditText activity_edittext; public DatePickerFragment(EditText edit_text) {

我在datepicker中选择日期，得到的是edittext:

13/12/2014

但我必须这样显示：

13 Dec 2014

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

public EditText activity_edittext;

public DatePickerFragment(EditText edit_text) {
    activity_edittext = edit_text;
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current date as the default date in the picker
    final Calendar c = Calendar.getInstance();
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);

    // Create a new instance of DatePickerDialog and return it
    return new DatePickerDialog(getActivity(), this, year, month, day);
}

    @Override
    public void onDateSet(DatePicker view, int year, int month, int day) {
        activity_edittext.setText(String.valueOf(day) + "/" + String.valueOf(month + 1 ) + "/" + String.valueOf(year));
    }
}

以同样的方式使用时间选择器，我得到如下值：

21:12

，我必须显示如下内容：

9:12 pm

public class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener {

        public EditText activity_edittext;

        public TimePickerFragment(EditText edit_text)
        {
            activity_edittext = edit_text;
        }

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            // Use the current time as the default values for the picker
            final Calendar c = Calendar.getInstance();
            int hour = c.get(Calendar.HOUR_OF_DAY);
            int minute = c.get(Calendar.MINUTE);

            // Create a new instance of TimePickerDialog and return it
            return new TimePickerDialog(getActivity(), this, hour, minute,
                    DateFormat.is24HourFormat(getActivity()));
        }

        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            activity_edittext.setText(String.valueOf(hourOfDay) + ":" + String.valueOf(minute));
        }
}

用于设置日期格式。因为您可以使用

dd-MMM-yyyy

格式从

13/12/2014

将日期设置为2014年12月13日

try {

    String dateString = String.valueOf(day) + "/" + String.valueOf(month + 1 ) + "/" + String.valueOf(year);
    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    Date date = sdf.parse(dateString);

    sdf = new SimpleDateFormat("dd MMM yyyy");
    String formatedDate = sdf.format(date);

} catch (Exception e) {}

或者，您可以使用

DateFormatSymbols

转换日期的月份，如下所示

String month = new DateFormatSymbols().getMonths()[month-1];

并将您的时间设置为

9:12 pm

，使用

hh:mm a

格式如下

try {

    String timeString = String.valueOf(hourOfDay) + ":" + String.valueOf(minute);
    SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
    Date time = sdf.parse(timeString);

    sdf = new SimpleDateFormat("hh:mm a");
    String formatedTime = sdf.format(time);

} catch (Exception e) {}

用于设置日期格式。因为您可以使用

dd-MMM-yyyy

格式从

13/12/2014

将日期设置为2014年12月13日

try {

    String dateString = String.valueOf(day) + "/" + String.valueOf(month + 1 ) + "/" + String.valueOf(year);
    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    Date date = sdf.parse(dateString);

    sdf = new SimpleDateFormat("dd MMM yyyy");
    String formatedDate = sdf.format(date);

} catch (Exception e) {}

或者，您可以使用

DateFormatSymbols

转换日期的月份，如下所示

String month = new DateFormatSymbols().getMonths()[month-1];

并将您的时间设置为

9:12 pm

，使用

hh:mm a

格式如下

try {

    String timeString = String.valueOf(hourOfDay) + ":" + String.valueOf(minute);
    SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
    Date time = sdf.parse(timeString);

    sdf = new SimpleDateFormat("hh:mm a");
    String formatedTime = sdf.format(time);

} catch (Exception e) {}

你设置错误了。您需要检查现在是哪个月，并根据它添加文本

请尝试以下设置日期：

@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
    String month_name="";
    switch(month) {
        case Calendar.JANUARY:
            month_name = "JAN";
        break;
        case Calendar.FEBRUARY:
            month_name = "FEB";

        case Calendar.MARCH:
            month_name = "MAR";
        break;
        case Calendar.APRIL:
            month_name = "APR";

        case Calendar.MAY:
            month_name = "MAY";
        break;
        case Calendar.JUNE:
            month_name = "JUN";

        case Calendar.JULY:
            month_name = "JUL";

        case Calendar.AUGUST:
            month_name = "AUG";
        break;
        case Calendar.SEPTEMBER:
            month_name = "SEP";
        case Calendar.OCTOBER:
            month_name = "OCT";
        break;
        case Calendar.NOVEMBER:
            month_name = "NOV";
        break;
        case Calendar.DECEMBER:
            month_name = "DEC";    
        break;
    }
    activity_edittext.setText(String.valueOf(day) + " " + month_name + " " + String.valueOf(year));
}

要设置12小时格式的时间，您需要检查其时间并相应地设置文本：

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
    String hour = "";
    String meridiem = "";
    Calendar datetime = Calendar.getInstance();
    datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
    datetime.set(Calendar.MINUTE, minute);

    if (datetime.get(Calendar.AM_PM) == Calendar.AM)
        meridiem = "AM";
    else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
        meridiem = "PM";

    hour = (datetime.get(Calendar.HOUR) == 0) ?"12":String.valueOf(datetime.get(Calendar.HOUR));
    activity_edittext.setText(hour + ":" + String.valueOf(minute) + " " + meridiem);
}

希望这有帮助。
