DatePicker.OnDateChangedListener called twice

Question

I\'m trying to create an app where the user selects a date from a DatePicker, and then a list is updated with some values.

My GUI looks like this:

Answer 1

private DatePicker.OnDateChangedListener dateSetListener = new DatePicker.OnDateChangedListener() {
    boolean fired = false;
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
         if (fired == true){
//Twince
         }
         else{
             Calendar c = Calendar.getInstance();
             c.set(year, monthOfYear, dayOfMonth);
             System.out.println ("TEST");
         }

    }
};
