Question

I am using a Datepicker in my application. What I am trying to do is getting the date already set in the text field and showing that on Datepicker control. But I am getting NumberFormatException when I use

Integer.parseInt(splittedDate[2])  //i.e the year column. 

When I see while debugging splittedDate containf three values which are fine. but while parsing year column at last index throws exception. I am unable to understand why is it so. pleasehelp me out of this. Following is the implementation of CreateDialog method for Datepicker.

@Override
protected Dialog onCreateDialog(int id) {
    if (id == DATE_DIALOG_ID) {
        if (birthDate.getText().toString().equalsIgnoreCase(""))
            return new DatePickerDialog(this, mDateSetListener, mYear,
                    mMonth, mDay);
        else {
            String[] splittedDate = birthDate.getText().toString().split("-");

            try{

                Log.i("Month String", splittedDate[0]);
                mMonth = Integer.parseInt(splittedDate[0]);
                Log.i("Day String", splittedDate[1]);
                mDay = Integer.parseInt(splittedDate[1]);
                Log.i("Year String", splittedDate[0]);
                mYear = Integer.parseInt(splittedDate[2]);

            }
            catch(Exception e)
            {
                Log.e("Number Format Exception Message: ",e.getMessage());
            }

            return new DatePickerDialog(this, mDateSetListener, mYear,
                    mMonth, mDay);

        }

    return null;
}

Here is the logCat info:

Post the code where you are inserting values in birthDate field. Check that there should not be any blank spaces. There should be digits only. from the Exception, it seems that '1970 ' contains a blank space. double check the birthDate field..
