Android AlertDialog onDismiss 获取用户选择

Question

考虑以下 AlertDialog：

pizzaOrderDialog = new AlertDialog.Builder(mContext);
    pizzaOrderDialog.setTitle("One last thing:");
    pizzaOrderDialog.setMessage("Would you like black or green olives?")
            .setCancelable(true)
            .setPositiveButton("Black", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    orderPizza("black");
                    Toast.makeText(mContext, "Ok! Thanks!", Toast.LENGTH_LONG).show();
                }
            })
            .setNegativeButton("Green", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    orderPizza("green");
                    Toast.makeText(mContext, "Ok! Thanks!", Toast.LENGTH_LONG).show();
                }
            });
    alertD = pizzaOrderDialog.create();

用户也可能选择通过触摸屏幕上的任意位置来关闭对话框，而不是单击 "Black" 或 "Green"。我想要的是 "catch" 这种情况，并在 onDismiss 中得到这种情况的指示：

alertD.setOnDismissListener(new DialogInterface.OnDismissListener() {

        @Override
        public void onDismiss(DialogInterface dialogInterface) {
            //TODO tell if dialog result was dialogInterface.BUTTON_NEGATIVE
            // or maybe dialogInterface.BUTTON_POSITIVE ?
        }
    });

此处的最佳做法是什么？谢谢！

显然，正如@CommonsWare 所指出的，我需要在这里使用 setOnCancelListener。
