解决方案还没有找到，我已经花了几个小时来应对这个挑战。当你按下“今天”按钮时，我怎样才能得到一个日期？

想要获得按下“今天”按钮时显示的日期。并且，我们相信试图将信息添加到指定日期的屏幕显示的过程。

    DatePickerDialog dpdialog = new DatePickerDialog(me, new OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int pickyear, int monthOfYear,
                int dayOfMonth) {

        }
    }, year, month-1, day);
    // Dialog(Positive Button)
    dpdialog.setButton(
            DialogInterface.BUTTON_POSITIVE,
            "set", 
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    // Positive Button
                    // How to get the date set
                    String day = dpdialog.getDayOfMonth();
                    String month = dpdialog.getMonth() + 1;
                    String year = dpdialog.getYear();
                }
            }    
            );

    // Dialog (Negative Button)
    dpdialog.setButton(
            DialogInterface.BUTTON_NEGATIVE, 
            "cancel", 
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    // Negative Button
                }
            }
            );

    // Dialog(Neutral Button)
    dpdialog.setButton(
            DialogInterface.BUTTON_NEUTRAL, 
            "today", 
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    // Neutral Button
                }
            }
            );

    dpdialog.show();

外部类中定义的变量将从内部类/内联方法中可见，因此您可以这样做：

private String day;
private String month;
private String year;

DatePickerDialog dpdialog = new DatePickerDialog(me, new OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int pickyear, int monthOfYear, int dayOfMonth) {
        // you have the picked year/month/day here.
        // For example:
        day = String.valueOf(dayOfMonth);
        month = String.valueOf(monthOfYear);
        year = String.valueOf(pickyear);
    }

}, year, month-1, day);
