android - 在日期选择器对话框中获取当前日期

Question

当用户单击但它不起作用时，我想在日期选择器对话框上获取当前日期。我的默认日期不会更改为我当前的日期。我在我的代码中做错了什么？

            Calendar mcurrentDate = Calendar.getInstance();

            int day   = mcurrentDate.get(Calendar.DAY_OF_MONTH);
            int month = mcurrentDate.get(Calendar.MONTH);
            int year  = mcurrentDate.get(Calendar.YEAR);

            DatePickerDialog dpd;
            dpd = new DatePickerDialog(getActivity(), 0,
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                int month, int day) {
                            // TODO Auto-generated method stub
                            dateTxtVu.setText("Date: " + day + "-" + month
                                    + "-" + year);
                            dateStr = day + "-" + month + "-" + year;
                        }

                    }, day, month, year);
            dpd.show();

您以错误的顺序传递值。您需要按以下顺序传递值：

public DatePickerDialog(Context context, int theme, OnDateSetListener listener, int year,
        int monthOfYear, int dayOfMonth)

像这样改变它：

Calendar mcurrentDate = Calendar.getInstance();

        int day   = mcurrentDate.get(Calendar.DAY_OF_MONTH);
        int month = mcurrentDate.get(Calendar.MONTH);
        int year  = mcurrentDate.get(Calendar.YEAR);

        DatePickerDialog dpd;
        dpd = new DatePickerDialog(getActivity(), 0,
                new DatePickerDialog.OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker view, int year,
                            int month, int day) {
                        // TODO Auto-generated method stub
                        dateTxtVu.setText("Date: " + day + "-" + month
                                + "-" + year);
                        dateStr = day + "-" + month + "-" + year;
                    }

                }, year, month, day);
        dpd.show();

year排在首位month，排day在最后。
