先看一下效果吧

完成效果

大家如果喜欢就一起来实现一下吧，顺便点一下关注呦，万一以后用的上呢！

那么,我们就开始吧。

首先当然还是依赖了

 Vlayout依赖
implementation 'com.alibaba.android:vlayout:1.0.3'
 //marqueeview 跑马灯依赖
 implementation 'com.sunfusheng:marqueeview:1.3.1'

布局

    也就一个Recycleryout布局

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recy"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

那么，开始上主菜了

 private void initView(View inflate) {
        mRecy = (RecyclerView) inflate.findViewById (R.id.recy);
        //创建Vlayout布局管理器
        VirtualLayoutManager virtualLayoutManager = new VirtualLayoutManager (getActivity ());
        //设置Vlayout布局管理器
        mRecy.setLayoutManager (virtualLayoutManager);
    
        final RecyclerView.RecycledViewPool pool = new RecyclerView.RecycledViewPool ();
        mRecy.setRecycledViewPool (pool);
        pool.setMaxRecycledViews (0, 10);
        //添加banner头布局
        BaseDelegeteAdapter adapter = new BaseDelegeteAdapter (getActivity (), new LinearLayoutHelper (),
                R.layout.vlayout_banner, 1) {
            @Override
            public void onBindViewHolder(BaseViewHolder holder, int i) {

                ArrayList<Uri> bannerList = new ArrayList<> ();
                bannerList.add (Uri.parse ("https://gw.alicdn.com/imgextra/i1/7/O1CN01nfNUEq1BvFJ6YLtPD_!!7-0" +
                        "-lubanu.jpg"));
                bannerList.add (Uri.parse ("https://gw.alicdn.com/imgextra/i3/20/O1CN01UTTfyr1C1CSm4hzOv_!!20" +
                        "-0" +
                        "-lubanu.jpg"));
                bannerList.add (Uri.parse ("https://gw.alicdn.com/imgextra/i3/106/O1CN01etvHvW1CeaWUFfTu9_" +
                        "!!106-0" +
                        "-lubanu.jpg"));
                bannerList.add (Uri.parse ("https://gw.alicdn.com/imgextra/i3/20/O1CN01UTTfyr1C1CSm4hzOv_!!20" +
                        "-0" +
                        "-lubanu.jpg"));
                bannerList.add (Uri.parse ("https://gw.alicdn.com/imgextra/i2/14/O1CN019L7VgZ1ByS5PJJpnO_!!14" +
                        "-0" +
                        "-lubanu.jpg"));
                bannerList.add (Uri.parse ("https://img.alicdn.com/tps/i4/TB1YMbpeoKF3KVjSZFESutExFXa.jpg"));

                //绑定数据
                Banner mBanner = holder.getView (R.id.banner);
                //设置banner样式
                mBanner.setBannerStyle (BannerConfig.CIRCLE_INDICATOR);
                //设置图片加载器

                mBanner.isAutoPlay (true);
                //设置轮播时间
                mBanner.setDelayTime (3000);
                //设置指示器位置(当banner模式中有指示器时)
                mBanner.setIndicatorGravity (BannerConfig.CENTER);
                //banner设置方法全部调用完毕时最后调用
                mBanner.start ();
                mBanner.setOnBannerListener (new OnBannerListener () {
