use

public void show() {
		//Set icon visability
		for (int i = 0; i < mMenu.size(); i++) {
			MenuItem item = mMenu.getItem(i);
			Drawable resIcon = item.getIcon();

			if (!item.isEnabled()) {
				resIcon.setAlpha(38);
			}

			item.setIcon(resIcon);
		}

		mPopup.show();
	}

when you have disabled icons
here you can set the alpha in percent:
resIcon.setAlpha(***);
