android - problem with datePicker, title initialization is funky -
so have reached end of rope when comes dang datepicker dialog working with. have made through 7 different activities within app , have not encountered single problem until reached datepicker. problem consists of 2 elements: 1) dang title of datepicker displays wednesday, december 31, 0002 when called. datepicker displays correctly, not title, , have not altered title 1 bit. when change date title changes correct information except for.... 2) appears if days of week off 1 (for today says monday, february 22, 2011). going post entire code within activity , if has ideas appreciated. issue going in oncreatedialog or onpreparedialog methods. if need remove of other extraneous init methods so, verify not causing problems anywhere else within activity.

frostysmooth,
i believe seeing incompatibility between android time , calendar data types using.
the enum values days of week inconsistent between them...
monday in calendar object has value of 0x2 see here.
monday in time object has value of 0x1 see here.
so when try set calendar object values time object, day off.
you need sort out when each being used adjust accordingly or stick single date/time object won't run these issues.
i hope able help, luck!
