如何在android kotlin中每27个用户加载图像后设置adview

问：

如何设置每加载 27 组用户图片后的 adview。每组图像（27个用户）加载后，必须将小广告显示到嵌套的滚动视图中。Kotlin 代码和 adview xml 如下所示：

    private fun loadNext27(peoples: List<PeopleNearByModelClass>) {

    try {

        coroutineScope.launch(Dispatchers.IO) {

            minPeopleCount =
                peopleNearbyFirstRow.size + peopleNearbySecondRow.size + peopleNearbyThirdRow.size
            val maxPeopleCount = peoples.size.coerceAtMost(minPeopleCount!! + 27)

            minPeopleCountDummy = maxPeopleCount

            peopleNearbyFirstRowList = ArrayList()
            peopleNearbySecondRowList = ArrayList()
            peopleNearbyThirdRowList = ArrayList()

            var i: Int = minPeopleCount as Int
            try {
                while (i < maxPeopleCount) {
                    i += 3
                    peopleNearbyFirstRowList.add(peoples[i])
                    peopleNearbySecondRowList.add(peoples[i + 1])
                    peopleNearbyThirdRowList.add(peoples[i + 2])

                    peopleNearbyFirstRow.add(peoples[i])
                    peopleNearbySecondRow.add(peoples[i + 1])
                    peopleNearbyThirdRow.add(peoples[i + 2])
                }
            } catch (e: Exception) {
                e.printStackTrace()
            }
            loadNext27UI(
                peopleNearbyFirstRowList,
                peopleNearbySecondRowList,
                peopleNearbyThirdRowList, peoples.size
            )
        }

    } catch (e: Exception) {
        e.printStackTrace()
    }
}

我想将此 adview 代码设置到此方法中。

private fun showAd() {

}

以下代码是我要将 AdView 添加到嵌套滚动视图中的 XML 代码：
