本文介绍了一个日期选择对话框的实现细节，包括如何通过反射获取并设置选中的日期，以及如何验证所选日期是否合法。此外，还提供了一个示例来说明如何处理用户选择的日期与当前日期的关系。

		mDateDialog.setButton(DialogInterface.BUTTON_POSITIVE, "确定",
				new OnClickListener() {

					@Override
					public void onClick(DialogInterface dialog, int which) {

						resetDialog(mDateDialog, true);
						Field field;
						try {
							field = dialog.getClass().getDeclaredField(
									"mCalendar");
							field.setAccessible(true);
							Calendar c = (Calendar) field.get(dialog);
							calendar.set(Calendar.YEAR, c.get(Calendar.YEAR));
							calendar.set(Calendar.MONTH, c.get(Calendar.MONTH));
							calendar.set(Calendar.DAY_OF_MONTH,
									c.get(Calendar.DAY_OF_MONTH));
							calendar.set(Calendar.HOUR, 0);
							calendar.set(Calendar.MINUTE, 0);
							calendar.set(Calendar.SECOND, 0);
							calendar.set(Calendar.MILLISECOND, 0);

							Calendar currentCalendar = Calendar
									.getInstance(Locale.CHINA);
							currentCalendar.set(Calendar.HOUR, 0);
							currentCalendar.set(Calendar.MINUTE, 0);
							currentCalendar.set(Calendar.SECOND, 0);
							currentCalendar.set(Calendar.MILLISECOND, 0);
							if (currentCalendar.before(calendar)
									|| currentCalendar.equals(calendar)) {

								String str = calendar.get(Calendar.YEAR) + "年"
										+ (calendar.get(Calendar.MONTH) + 1)
										+ "月"
										+ calendar.get(Calendar.DAY_OF_MONTH)
										+ "日";
								text_value_product_deli_time.setText(str);

							} else {

								resetDialog(mDateDialog, false);
								ToastUtils.t(mContext, "您不能穿越");

							}
						} catch (NoSuchFieldException e) {
							e.printStackTrace();
						} catch (IllegalArgumentException e) {
							e.printStackTrace();
						} catch (IllegalAccessException e) {
							e.printStackTrace();
						}

					}
				});
