DatePickerDialog中为什么点击屏幕外不消失？

Question

final Calendar objTime = Calendar.getInstance();
int iYear = objTime.get(Calendar.YEAR);
int iMonth = objTime.get(Calendar.MONTH);
int iDay = objTime.get(Calendar.DAY_OF_MONTH);

    DatePickerDialog datePickerDialog = new DatePickerDialog(QueryDateActivity.this, DatePickerListener, iYear, iMonth, iDay);
    datePickerDialog.setCanceledOnTouchOutside(true);
    datePickerDialog.show();

            我已经设置为true了 可是还是不消失为什么？
            /**下面是原代码
            */
               final DatePickerDialog mDialog_start = new DatePickerDialog(this, null,
                    con_year_start, con_month_start, con_day_start);
            //手动设置按钮
            mDialog_start.setButton(DialogInterface.BUTTON_POSITIVE, "完成", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    //通过mDialog.getDatePicker()获得dialog上的DatePicker组件，然后可以获取日期信息
                    DatePicker datePicker = mDialog_start.getDatePicker();
                    int year = datePicker.getYear();
                    int month = datePicker.getMonth();
                    int day = datePicker.getDayOfMonth();
                    tv_start.setText(year+"/"+months[month]+"/"+day);
                    con_year_start = year;
                    con_month_start = month;
                    con_day_start = day;
                }
            });
            //取消按钮，如果不需要直接不设置即可
            mDialog_start.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    mDialog_start.dismiss();
                }
            });
            mDialog_start.setTitle("请选择开始时间");
            mDialog_start.setCanceledOnTouchOutside(true);
            mDialog_start.show();
