final ViewGroup decorView = (ViewGroup) getActivity().getWindow().getDecorView().findViewById(android.R.id.content);
final ImageView guideImage = new ImageView(getActivity());
//                //guideImage.setAlpha(5);
        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        guideImage.setLayoutParams(params);
        guideImage.setScaleType(ImageView.ScaleType.FIT_XY);
        guideImage.setImageResource(imageResource[guideIndex]);
        guideImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                decorView.removeView(guideImage);
                guideIndex++;
                addGuideImage();
            }
        });
        decorView.addView(guideImage);//添加引导图片

这个是需要美工提供图片。
