Question

我有使用datepicker的android代码。目前我得到的输出是11-2-14的形式。我希望格式为2-NOV-14.Below是我当前代码的一部分：

final Calendar c = Calendar.getInstance();
           year=c.YEAR;
            month=c.MONTH+1;
            day=c.DAY_OF_MONTH;
@Override
        protected Dialog onCreateDialog(int id) {
            switch (id) {
            case DATE_PICKER_ID1:


                // set date picker for current date 

                return new DatePickerDialog(this, pickerListener1, year, month,day);


           case DATE_PICKER_ID2:


                // set date picker for current date 

                return new DatePickerDialog(this, pickerListener2, year, month,day);


            }
            return null;
        }

        private DatePickerDialog.OnDateSetListener pickerListener1 = new DatePickerDialog.OnDateSetListener() {

            // when dialog box is closed, below method will be called.
            @Override
            public void onDateSet(DatePicker view, int selectedYear,
                    int selectedMonth, int selectedDay) {

                year  = selectedYear;
                month = selectedMonth;
                day   = selectedDay;

                // Show selected date 
                 date1=""+day+"-"+month+"-"+year+" ";
                Output1.setText(new StringBuilder().append(day).append("-").append(month + 1).append("-").append(year).append(" "));



               }
            };
            private DatePickerDialog.OnDateSetListener pickerListener2 = new DatePickerDialog.OnDateSetListener() {

                // when dialog box is closed, below method will be called.
                @Override
                public void onDateSet(DatePicker view, int selectedYear,
                        int selectedMonth, int selectedDay) {

                    year  = selectedYear;
                    month = selectedMonth;
                    day   = selectedDay;

                    // Show selected date 
                     date2=""+day+"-"+month+"-"+year+" ";
                   Output2.setText(new StringBuilder().append(month + 1)
                            .append("-").append(day).append("-").append(year)
                            .append(" "));


                   }
                };

以上代码的日期格式为11-2-14。请帮助。

Answer 1

首先，您必须将当天与月份交换：

year = selectedYear; month = selectedDay; day = selectedMonth;

然后在类中添加一个私有静态final String数组作为字段，其中s [i]包含一年中第（i-1）个月的字符串represntation：s [10] =“NOV”和你替换

month = selectedDay; 与

month = s[selectedDay];

Answer 2

尝试以下代码：

public void onDateSet(DatePicker view, int selectedYear,
                    int selectedMonth, int selectedDay) {

                year  = selectedYear;
                month = selectedMonth;
                day   = selectedDay;

                // Show selected date 
                 date1=""+day+"-"+month+"-"+year+" ";
                String mon = formatMonth(month+1);
                Output1.setText(day+"-"+mon+"-"+year);
               }
            };



public String formatMonth(int month) {
    Locale locale;
    DateFormat formatter = new SimpleDateFormat("MMM", locale);
    GregorianCalendar calendar = new GregorianCalendar();
    calendar.set(Calendar.MONTH, month-1);
    return formatter.format(calendar.getTime());
}

如何在android中更改datepicker格式？
