setMinDate() for DatePicker doesn't work

问题

DatePicker datepicker = (DatePicker) view.findViewById(R.id.ad_date_picker);
datepicker.setMinDate(Calendar.getInstance().getTimeInMillis());

It just doesn't work. It works only in the xml (android:minDate="mm/dd/yyyy"), but I need to set the minimum date dynamically to the current day. My minimum API is 11.

P.S: Solution used to work before but might be outdated now.

Try something like this. If I understand correctly, you wish to set the minimum date of spinner to today's date. It works for me without giving any error:

    Calendar cal = Calendar.getInstance();
    cal.set(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH), 0, 0, 0);
    long time = cal.getTimeInMillis();
    DatePicker datepicker = (DatePicker) findViewById(R.id.datePicker);
    datepicker.setMinDate(time);

In your xml I am supposing that you have something like this:

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
