protected Dialog onCreateDialog(int ID) {    switch (ID) {    case TIME_DIALOG_ID:        return new TimePickerDialog(ListReminderActivity.this,mTimeSetListener,mHour,mMinute,false);    case DATE_DIALOG_ID:        return new DatePickerDialog(ListReminderActivity.this,mDateSetListener,mYear,mMonth,mDay);    case DESCRIPTION_DIALOG_ID:        return new AlertDialog.Builder(ListReminderActivity.this).setTitle(                "Add Reminder").setVIEw(description).setPositivebutton(                R.string.add_alert_ok,new DialogInterface.OnClickListener() {                    public voID onClick(DialogInterface dialog,int whichbutton) {                        ListReminderActivity.this                                .dismissDialog(DESCRIPTION_DIALOG_ID);                        ListReminderActivity.this                                .removeDialog(DESCRIPTION_DIALOG_ID);                        ListReminderActivity.this                                .showDialog(DATE_DIALOG_ID);                    }                }).setNegativebutton(R.string.add_alert_cancel,int whichbutton) {                        ListReminderActivity.this                                .dismissDialog(DESCRIPTION_DIALOG_ID);                        ListReminderActivity.this                                .removeDialog(DESCRIPTION_DIALOG_ID);                    }                }).create();    }    return null;}

但问题是..当我按下确定按钮时,我得到了例外
