public class ShowAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

private Context context;
private List<Object>list=new ArrayList<>();

    }else if (i == 1){

    }else if (i == 2){

    }else if(i==3){
        view = LayoutInflater.from(context).inflate(R.layout.item_xbanner,viewGroup,false);
        holder=new PzshViewHolder(view);
    }
    return holder;

@Override
public void onBindViewHolder(@NonNull final RecyclerView.ViewHolder viewHolder, int i) {

    if (list.get(i) instanceof BannerBean){

    }

public class BannerViewHolder extends RecyclerView.ViewHolder{

    private XBanner xbanner;
