Java Facebook原生广告与回收者视图

我知道这个问题被问了好几次，并且得到了不同的人的回答。 我想在Recycler视图中显示Facebook原生广告，我已经创建了一个适配器，如下所示

package com.zurmati.ilock.Adapter;

public class MyNativeAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    Context context;
    List<Themes> themesList;
    NativeAdsManager nativeAdsManager;
    int adItems = 0;

    List<NativeAd> mAdItems;

    private static final int AD_DISPLAY_FREQUENCY = 3;
    private static final int POST_TYPE = 0;
    private static final int AD_TYPE = 1;

    public MyNativeAdapter(Context context, List<Themes> themesList, NativeAdsManager nativeAdsManager) {
        this.context = context;
        this.themesList = themesList;
        this.nativeAdsManager = nativeAdsManager;
        mAdItems = new ArrayList<>();
    }

这是我的onBindViewHolder类，我在其中绑定元素

 @Override
    public void onBindViewHolder(@NonNull final RecyclerView.ViewHolder holder, int position) {
        int viewType = getItemViewType(position);
        switch (viewType) {
            case AD_TYPE:
                NativeAd ad;
                if (mAdItems.size() > position / AD_DISPLAY_FREQUENCY) {
                    ad = mAdItems.get(position / AD_DISPLAY_FREQUENCY);

                } else {
                    ad = nativeAdsManager.nextNativeAd();
                    if (ad != null) {
                        if (!ad.isAdInvalidated()) {
                            mAdItems.add(ad);
                        }
                    }
                }

                UnifiedFbHolder adHolder = (UnifiedFbHolder) holder;
                adHolder.adChoicesContainer.removeAllViews();

                if (ad != null) {
                    adHolder.tvAdTitle.setText(ad.getAdvertiserName());
                    adHolder.tvAdBody.setText(ad.getAdBodyText());
                    adHolder.tvAdSocialContext.setText("Sponsored");
                    adHolder.btnCallToAction.setText(ad.getAdCallToAction());
                    adHolder.btnCallToAction.setVisibility(ad.hasCallToAction() ? View.VISIBLE : View.INVISIBLE);

                    AdOptionsView adOptionsView = new AdOptionsView(context, ad, adHolder.nativeAdLayout);
                    adHolder.adChoicesContainer.addView(adOptionsView, 0);

                    List<View> clickAbleViews = new ArrayList<>();
                    clickAbleViews.add(adHolder.ivAdIcon);
                    clickAbleViews.add(adHolder.mvAdMedia);
                    clickAbleViews.add(adHolder.btnCallToAction);
                    ad.registerViewForInteraction(adHolder.nativeAdLayout, adHolder.mvAdMedia,
                            adHolder.ivAdIcon, clickAbleViews);

                }

                break;

            case POST_TYPE:
                final ImageViewHolder imageViewHolder = (ImageViewHolder) holder;

                try {
                    Glide.with(context).load(themesList.get(holder.getAdapterPosition()).getImage()).into(imageViewHolder.imgTheme);

                } catch (Exception e) {
                    e.printStackTrace();
                }
                //Event
                imageViewHolder.setListener((v, pos) -> {
                    EventBus.getDefault().post(new ThemesItemClickEvent(themesList.get(pos).getImage(), pos, true));
                });
                break;
        }
    }

}

这是我的主要活动代码

    }

    private void initViews() {
        themesList = new ArrayList<>();


        addAdsToList();
        //Add themes into the list

    }
