Answer 1

That is because the last 3 parameters on the DatePickerDialog constructor are the date to be shown initially in the DatePicker. You are setting the dateTime variable to the current day with

private Calendar dateTime = Calendar.getInstance();

So you must set your dateTime variable to the correct date you want to be shown on the first run. In your OnCreate() method do this

dateTime.set(1980, Calendar.JANUARY , 1);

Now your DatePicker should show the correct value on the first run and since you set the dateTime variable in the callback it should set the correct previous value if the user opens up the dialog again.
