I want to show an advanced native ad inside a RecyclerView
this is the code I have tried inside the adabter
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
return when (viewType) {
ITEM_SONG -> {
val view = LayoutInflater.from(parent.context)
.inflate(R.layout.song_card, parent, false)
SongViewHolder(view)
}
else -> {
val bannerView = LayoutInflater.from(parent.context)
.inflate(R.layout.ad_frame, parent)
AdViewHolder(bannerView)
}
}
}
private fun populateUnifiedNativeAdView(nativeAd: UnifiedNativeAd, adView: UnifiedNativeAdView) {
adView.mediaView = adView.findViewById(R.id.ad_media)
adView.headlineView = adView.findViewById(R.id.ad_headline)
adView.bodyView = adView.findViewById(R.id.ad_body)
adView.callToActionView = adView.findViewById(R.id.ad_call_to_action)
(adView.headlineView as TextView).text = nativeAd.headline
adView.mediaView.setMediaContent(nativeAd.mediaContent)
if (adView.bodyView == null) {
adView.bodyView.visibility = View.INVISIBLE
} else {
adView.bodyView.visibility = View.VISIBLE
(adView.bodyView as TextView).text = nativeAd.body
}
if (adView.callToActionView == null) {
adView.callToActionView.visibility = View.INVISIBLE
} else {
adView.callToActionView.visibility = View.VISIBLE
(adView.callToActionView as TextView).text = nativeAd.callToAction
}
adView.setNativeAd(nativeAd)
}
inside the onBindViewHolder
ITEM_BANNER -> {
val adViewHolder = holder as AdViewHolder
val parent = adViewHolder.itemView as ViewGroup
val adView = LayoutInflater.from(App.context)
.inflate(R.layout.ad_unified, null) as UnifiedNativeAdView
val builder = AdLoader.Builder(App.context, NATIVE_ID)
.forUnifiedNativeAd { unifiedNativeAd: UnifiedNativeAd? ->
if (unifiedNativeAd != null) {
populateUnifiedNativeAdView(unifiedNativeAd, adView)
parent.removeAllViews()
parent.addView(adView)
}
}
val videoOptions = VideoOptions.Builder()
.setStartMuted(true)
.build()
val adOptions = NativeAdOptions.Builder()
.setVideoOptions(videoOptions)
.build()
builder.withNativeAdOptions(adOptions)
builder.build().loadAd(AdRequest.Builder().build())
}
}
}
in MainActivity this code is used to add the FrameLayout to the list of items
private fun getNativeAds(list: ArrayList<Any>) {
var i = 0
while (i < list.size) {
list.add(i, FrameLayout(this@MainActivity))
i += ITEMS_PER_AD
}
}
I get this error

Please check your method:
getItemViewType(position: Int): Int
It might not returning the correct itemView type
