BannerLayout recyclerBanner = findViewById(R.id.recycler);
bannerVertical = findViewById(R.id.recycler_ver);
List<String> list = new ArrayList<>();
list.add("http://img0.imgtn.bdimg.com/it/u=1352823040,1166166164&fm=27&gp=0.jpg");
list.add("http://img3.imgtn.bdimg.com/it/u=2293177440,3125900197&fm=27&gp=0.jpg");
list.add("http://img3.imgtn.bdimg.com/it/u=3967183915,4078698000&fm=27&gp=0.jpg");

list.add("http://img4.imgtn.bdimg.com/it/u=1243617734,335916716&fm=27&gp=0.jpg");
WebBannerAdapter webBannerAdapter=new WebBannerAdapter(this,list);
webBannerAdapter.setOnBannerItemClickListener(new BannerLayout.OnBannerItemClickListener() {
