protected void hideKeyboard() {
    final Activity activity = getActivity();
    final View view = activity != null ? activity.getCurrentFocus() : null;
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            if (view != null) {
                InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
                if (imm != null)
                    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
            }
        }
    }, 1);
}

@Override
public void onDismiss(DialogInterface dialog) {
    super.onDismiss(dialog);
    hideKeyboard();
}
