setMinDate(…) for DatePicker doesn't work when invoked a second time

Question

I\'m in a particular situation in which I have to alter the min and max date of DatePicker according to the selected element of a Spinner. Here\'s

Answer 1

This happens because method setMinDate() has check

 if (mTempDate.get(Calendar.YEAR) == mMinDate.get(Calendar.YEAR)
                && mTempDate.get(Calendar.DAY_OF_YEAR) != mMinDate.get(Calendar.DAY_OF_YEAR){
            return;
 }

Simple workaround is to set min date with different year at first, for example

mPicker.setMinDate(0);

mPicker.setMinDate(new LocalDate().minusWeeks(2)
                                .toDateTimeAtStartOfDay().getMillis());

It works for me.
