使用方法

设置一个带数据的RecyclerView.Adapter即可。

   <com.example.library.banner.BannerLayout
        android:id="@+id/recycler"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        app:autoPlaying="true"
        app:centerScale="1.3"
        app:itemSpace="20"
        app:moveSpeed="1.8"/>

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://img0.imgtn.bdimg.com/it/u=3184221534,2238244948&fm=27&gp=0.jpg");
        list.add("http://img4.imgtn.bdimg.com/it/u=1794621527,1964098559&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() {
            @Override
            public void onItemClick(int position) {
                Toast.makeText(MainActivity.this, "点击了第  " + position+"  项", Toast.LENGTH_SHORT).show();
            }
        });
recyclerBanner.setAdapter(webBannerAdapter);
