I have created twoe viewHolders in my RecyclerView class, one for the contents and the other for facebook native ads, My app clash immediately after running it. How do I overcome this?
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
switch (viewType) {
case 0:
return new ViewHolderBoxOffice(layoutInflater.from(parent.getContext()).inflate(R.layout.custom_movie_box_office, parent, false));
case 2:
return new NativeAdViewHolder(layoutInflater.from(parent.getContext()).inflate(R.layout.custom_ads_facebook, parent, false));
}
return null;
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
switch (holder.getItemViewType()) {
case 0:
ViewHolderBoxOffice v_holder = (ViewHolderBoxOffice) holder;
Movie currentMovie = mlistMovies.get(position);
v_holder.movieTitle.setText(currentMovie.getTitle());
Date movieReleaseDate = currentMovie.getReleaseDateTheater();
if (movieReleaseDate != null) {
String formmattedDate = dateFormat.format(movieReleaseDate);
v_holder.movieReleaseDate.setText(formmattedDate);
} else {
v_holder.movieReleaseDate.setText(Constants.NA);
}
int audienceScore = currentMovie.getAudienceScore();
if (audienceScore == -1) {
v_holder.movieAudienceScore.setRating(0.0F);
v_holder.movieAudienceScore.setAlpha(0.5F);
} else {
v_holder.movieAudienceScore.setRating(currentMovie.getAudienceScore() / 20.0F);
v_holder.movieAudienceScore.setAlpha(1.0F);
}
String urlThumbnail = currentMovie.getUrlThumbnail();
loadImages(urlThumbnail, v_holder);
case 2:
NativeAdViewHolder mHolder=(NativeAdViewHolder)holder;
// Setting the Text.
nativeAd.unregisterView();
mHolder.nativeAdCallToAction.setText(nativeAd.getAdCallToAction());
mHolder.nativeAdSocialContext.setText(nativeAd.getAdSocialContext());
mHolder.nativeAdTitle.setText(nativeAd.getAdTitle());
mHolder.nativeAdBody.setText(nativeAd.getAdBody());
// Downloading and setting the ad icon.
NativeAd.Image adIcon = nativeAd.getAdIcon();
NativeAd.downloadAndDisplayImage(adIcon, mHolder.nativeAdIcon);
// Download and setting the cover image.
NativeAd.Image adCoverImage = nativeAd.getAdCoverImage();
mHolder.nativeAdMedia.setNativeAd(nativeAd);
// Add adChoices icon
// if (adChoicesView == null)
if(! (mHolder.adview.getChildAt(0) instanceof AdChoicesView)){
AdChoicesView adChoicesView = new AdChoicesView(layoutInflater.getContext(), nativeAd, true);
mHolder.adview.addView(adChoicesView, 0);
}
nativeAd.registerViewForInteraction( mHolder.adview);
default:
break;
}
if (position > previousPosition) {
comeagain.materialdesign.anim.AnimationUtils.animate(holder, true);
} else {
comeagain.materialdesign.anim.AnimationUtils.animate(holder, false);
}
previousPosition = position;
}
private void loadImages(String urlThumbnail, final ViewHolderBoxOffice holder) {
if (urlThumbnail != null) {
imageLoader.get(urlThumbnail, new ImageLoader.ImageListener() {
@Override
public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
holder.movieThumbnail.setImageBitmap(response.getBitmap());
}
@Override
