防止在android的Datetime选择器模式中从当前小时选择过去的小时？

// 获取当前的日期和时间
Calendar calendar = Calendar.getInstance();
int currentYear = calendar.get(Calendar.YEAR);
int currentMonth = calendar.get(Calendar.MONTH);
int currentDay = calendar.get(Calendar.DAY_OF_MONTH);
int currentHour = calendar.get(Calendar.HOUR_OF_DAY);
int currentMinute = calendar.get(Calendar.MINUTE);

// 创建一个自定义的Datetime选择器
DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
        // 当用户选择日期时，检查所选的小时是否是过去的小时
        if (year == currentYear && month == currentMonth && dayOfMonth == currentDay) {
            TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                    // 检查所选的小时是否是过去的小时
                    if (hourOfDay >= currentHour) {
                        // 处理选择的日期和时间
                        // ...
                    } else {
                        Toast.makeText(MainActivity.this, "请选择一个未来的时间", Toast.LENGTH_SHORT).show();
                    }
                }
            }, currentHour, currentMinute, true);
            timePickerDialog.show();
        } else {
            Toast.makeText(MainActivity.this, "请选择今天的日期", Toast.LENGTH_SHORT).show();
        }
    }
}, currentYear, currentMonth, currentDay);
datePickerDialog.getDatePicker().setMinDate(calendar.getTimeInMillis());
datePickerDialog.show();
