我正在嘗試在 RecyclerView 中實(shí)現(xiàn) Admob 廣告。我嘗試了很多例子，但都失敗了。我想在我的 RecyclerView 的 3 個(gè)項(xiàng)目之間插入一個(gè)廣告，我正在使用 GridLayout 和 Admob 橫幅。我想要我的應(yīng)用程序視圖，如下所示。任何幫助，將不勝感激。我的 RecyclerView 適配器  class ProductAdapter(private val userList: ArrayList<Model.ProductList>, private val context: Context, private val which: String) : androidx.recyclerview.widget.RecyclerView.Adapter<RecyclerView.ViewHolder>() {override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {    if (holder.itemViewType == 0) {        holder as MyViewHolder2        val adRequest = AdRequest.Builder().build()        holder.adView.loadAd(adRequest)        holder.adView.adListener = object : AdListener() {            override fun onAdFailedToLoad(errorCode: Int) {                Log.d("errorCode", errorCode.toString())            }        }    } else {        holder as MyViewHolder        val magazineList: Model.ProductList = userList[position]        Glide.with(context).load(magazineList.featured_image)            .thumbnail(0.5f)            .into(holder.image)        holder.title.text = magazineList.post_title        holder.views.text = magazineList.count        holder.date.text = magazineList.offer_valid        }    }}override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {    if (viewType == 0) {        return MyViewHolder2(LayoutInflater.from(parent.context).inflate(R.layout.ad_list_row, parent, false))    } else {        return MyViewHolder(LayoutInflater.from(parent.context).inflate(R.layout.product_list_row, parent, false))    }}override fun getItemCount(): Int {    return userList.size}override fun getItemViewType(position: Int): Int {    return if (position>0 && position % 3== 0) {        0    } else {        1    }  }
