java.lang.IllegalArgumentException: current should be >= start and

问题

I am trying to implement date picker on a button in android. But as soon as i click on the button error pops up. But time picker runs fine. Here's the code:

mPickDate.setOnClickListener(new View.OnClickListener() {       //Assigning onClickListener to Date Button                                                                  
        public void onClick(View v) {
            showDialog(DATE_DIALOG_ID);
            }    
    });

    pickTime.setOnClickListener(new View.OnClickListener() {        //Assigning onClickListener to Time Button

        @Override
        public void onClick(View v) {
            showDialog(TIME_DIALOG_ID);

        }
    });
    }

    @Override
    protected Dialog onCreateDialog(int id) {                       //Overriding onCreateDialog()
        switch (id) {
        case DATE_DIALOG_ID:
            return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
        case TIME_DIALOG_ID:
            return new TimePickerDialog(this,mTimeSetListener,mHour,mMin,true);

        }
        return null;
    }

    TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() {        //Defining the TimePickerDialog reference variable

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            mHour=hourOfDay;
            mMin= minute;
            updateTime();
        }
    };

    DatePickerDialog.OnDateSetListener mDateSetListener =                       //Defining the DatePickerDialog reference variable
        new DatePickerDialog.OnDateSetListener() {

            public void onDateSet(DatePicker view, int year, 
                                  int monthOfYear, int dayOfMonth) {
                mYear = year;
                mMonth = monthOfYear;
                mDay = dayOfMonth;
                updateDisplay();
            }
        };

Here's the logcat:

I've got the same problem but I found solution. You should initialize mYear,mMonth,mDay:

//Init this variables as you wish eg.:
private int mYear = 2010;
private int mMonth = 11;
private int mDay =1;
@Override
protected Dialog onCreateDialog(int id) {                       //Overriding onCreateDialog()
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
    case TIME_DIALOG_ID:
        return new TimePickerDialog(this,mTimeSetListener,mHour,mMin,true);

    }
    return null;
}
