点击的插页式广告

Question

我想在点击（addButton）时添加非页内广告。

addButton = findViewById(R.id.add_to_whatsapp_button);
    alreadyAddedText = findViewById(R.id.already_added_text);
    layoutManager = new GridLayoutManager(this, 1);
    recyclerView = findViewById(R.id.sticker_list);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.getViewTreeObserver().addOnGlobalLayoutListener(pageLayoutListener);
    recyclerView.addOnScrollListener(dividerScrollListener);
    divider = findViewById(R.id.divider);
    if (stickerPreviewAdapter == null) {
        stickerPreviewAdapter = new StickerPreviewAdapter(getLayoutInflater(), R.drawable.sticker_error, getResources().getDimensionPixelSize(R.dimen.sticker_pack_details_image_size), getResources().getDimensionPixelSize(R.dimen.sticker_pack_details_image_padding), stickerPack);
        recyclerView.setAdapter(stickerPreviewAdapter);
    }
    packNameTextView.setText(stickerPack.name);
    packPublisherTextView.setText(stickerPack.publisher);
    packTrayIcon.setImageURI(StickerPackLoader.getStickerAssetUri(stickerPack.identifier, stickerPack.trayImageFile));
    packSizeTextView.setText(Formatter.formatShortFileSize(this, stickerPack.getTotalSize()));
    addButton.setOnClickListener(v -> addStickerPackToWhatsApp(stickerPack.identifier, stickerPack.name));
    if (getSupportActionBar() != null) {
        getSupportActionBar().setDisplayHomeAsUpEnabled(showUpButton);
        getSupportActionBar().setTitle(showUpButton ? R.string.title_activity_sticker_pack_details_multiple_pack : R.string.title_activity_sticker_pack_details_single_pack);
    }
}
