Android: Android 4.1 Emulator Invoking onDateSet Twice from DatePicker Dialog


My application was working perfectly on my Android 2.2 emulator. I then decided to test on an Android 4.1 emulator. The DatePickerDialog looks a little different and for some reason when I press on "Done", the onDateSet() listener gets called twice and causes problems in my application.

I know this because the log shown below in the code is printed twice whenever I click on "Done"

mDateSetListener = new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            Log.v("onDateSet", "ENTERED");
            //rest of code...
    }};

Solution

  • Try setting a boolean to check for a double fire within the same dialog. Something similar to:

    Calendar c = Calendar.getInstance();
    c.add(Calendar.DAY_OF_YEAR, 1);
    final DatePickerDialog dateDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
        boolean fired = false;
        public void onDateSet(final DatePicker view, final int year, final int monthOfYear, final int dayOfMonth) {
            Log.i("PEW PEW", "Double fire check");
            if (fired) {
                Log.i("PEW PEW", "Double fire occured. Silently-ish returning");
                return;
            } else {
                //first time fired
                fired = true;
            }
            //Normal date picking logic goes here
        }
    }, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));
    dateDialog.show();
    

    This double fire issue also happens with onTimeSet of a TimePickerDialog and this check also works for those.
