Just setOnShowListener() to AlertDialog, and set focus on the negative button.

    alertDialog.setOnShowListener(new DialogInterface.OnShowListener(){

        @Override
        public void onShow(DialogInterface dialog) {

            Button negative = alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE);
            negative.setFocusable(true);
            negative.setFocusableInTouchMode(true);
            negative.requestFocus();
        }
    });
    alertDialog.show();
