如何在我的数据项之间添加原生广告？

Question

我创建了一个带有自定义适配器的回收站视图，我想在我的商品的每个第三个位置显示原生广告。但无论我写什么，它都会与我的项目重叠，最重要的是，会显示原生广告。但我不想要这个。

public class Event_Discover_Combined_Adapter extends RecyclerView.Adapter<Event_Discover_Combined_Adapter.MyViewHolder> {

private Context context;
private ArrayList<Event_Discover_Combined_Details> beanList;
private int itemCount;

public Event_Discover_Combined_Adapter(Context context, ArrayList<Event_Discover_Combined_Details> beanList, int itemCount) {
    this.context = context;
    this.beanList = beanList;
    this.imageLoader = ImageLoader.getInstance();
    this.itemCount = itemCount;

}

//int viewType ;
@Override
public int getItemViewType(int position) {
    if (position % 3 == 0) {
        return R.layout.native_ad_frame_layout;
    } else {
        if (beanList.get(position).getType() == ConstantUrl.TYPE_EVENT) {
            return R.layout.events_item;
        } else {
            return R.layout.discover_item;

    }

我想知道在哪里添加检查以隐藏和取消隐藏项目。假设我有 6 个项目。因此，在 recyclerview 中，它应该显示 9 个项目，包括原生广告。 （每第三个位置）。

Answer 1

 if (position == 0 || (position + 1) % 3 == 0) { //add your nativeAdd here }
