【Android】Banner2.1的使用

com.youth.banner.Banner 2.1的使用

与前版本不同的是，2.1版本是用的适配器

设置适配器和点击事件

banner.setAdapter(new MyBannerAdapter(rows));
banner.setOnBannerListener(new OnBannerListener() {
    @Override
    public void OnBannerClick(Object o, int i) {
        Log.d(TAG, "OnBannerClick: " + i);
    }
});

适配器

public class MyBannerAdapter extends BannerAdapter<XXXBean.XXX, MyBannerAdapter.MHolder> {

    public MyBannerAdapter(List<XXXBean.XXX> datas) {
        super(datas);
    }

    @Override
    public MHolder onCreateHolder(ViewGroup parent, int viewType) {
        ImageView imageView = new ImageView(parent.getContext());
        //注意，必须设置为match_parent，这个是viewpager2强制要求的
        ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        imageView.setLayoutParams(params);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        return new MHolder(imageView);
    }

    @Override
    public void onBindView(MHolder mHolder, HomeBannerBean.RowsDTO rowsDTO, int i, int i1) {
		//图片在这里处理，我处理了一下圆角，若不需要则删除apply(options)
        RoundedCorners roundedCorners = new RoundedCorners(20);
        RequestOptions options = RequestOptions.bitmapTransform(roundedCorners);
        Glide.with(mHolder.itemView).load(SPUtil.getString("http") + rowsDTO.getAdvImg()).apply(options).into(mHolder.imageView);
    }

    class MHolder extends RecyclerView.ViewHolder {
        ImageView imageView;

        public MHolder(@NonNull ImageView view) {
            super(view);
            this.imageView = view;
        }
    }
}
