    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        //轮播图
        banner = (Banner) view.findViewById(R.id.main_banner);
        bannerlist = new ArrayList<>();

        bannerlist.add("https://w1.hoopchina.com.cn/52/b0/2b/52b02b490c6f833494d28cb516cdba27001.jpg");

        banner.setImageLoader(new ImageLoader() {
            @Override

                Glide.with(context).load(path).asBitmap().into(imageView);
            }
        });
        banner.setImages(bannerlist);
        banner.setBannerAnimation(Transformer.BackgroundToForeground);
        banner.setDelayTime(5000);
        banner.setIndicatorGravity(BannerConfig.CENTER);
        banner.start();
    }
