Java – Use a different View in onCreateViewHolder

I followed this Google Developer’s YouTube channel tutorial for implementing AdMob native fast ads.

I get the following error:

required: packagename.adapter.viewHolder
found   : packagename.adapter.NativeExpressAdViewHolder

This is what my onCreateViewHolder looks like:

public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    switch (viewType) {
        case AD_VIEW_TYPE:
            View nativeExpressLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.native_express_add_container, parent, false);
            return new NativeExpressAdViewHolder(nativeExpressLayoutView); 
        case MENU_ITEM_VIEW_TYPE:
            default:
            View myLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list, parent, false);
            return new ViewHolder(myLayoutView);
    }
}

Here are my 2 different ViewHolder classes:

class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {      

ViewHolder(View itemView) {
        super(itemView);
    }          
}

public class NativeExpressAdViewHolder extends RecyclerView.ViewHolder {
    NativeExpressAdViewHolder(View view) {
        super(view);
    }
}

This is a mock question with no answer:

• Error “Incompatible types” while adding NativeAds in recyclerView
• How to add NativeExpressAdView with Custom Model List Android?

Edit:

Here is the full adapter I asked for :

public class MainActivityVideoAdapter extends Adapter<MainActivityVideoAdapter.ViewHolder> {
ArrayList<Bitmap> bitmapArrayList;
Context context;
LayoutInflater layoutInflater;
View myLayoutView;
ArrayList<PathModel> ThumbPathList;
ArrayList<PathModel> VideoPathList = new ArrayList();
static DBManager manager;
long _id;

private static final int MENU_ITEM_VIEW_TYPE = 0;
private static final int AD_VIEW_TYPE = 1;

class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    Video Title
    TextView videoName;
    Video Image
    CircularImageView videoThumb;
    PopupMenu
    ImageButton viewholderOtions;

ViewHolder(View itemView) {
        super(itemView);
        viewholderOtions = (ImageButton) myLayoutView.findViewById(R.id.viewholderOptions);
        videoName = (TextView) myLayoutView.findViewById(R.id.FilePath);
        videoThumb = (CircularImageView) myLayoutView.findViewById(R.id.VideoThumbnail);
        View onClick
        itemView.setOnClickListener(this);
        Popup onClick
        viewholderOtions.setOnClickListener(this);
    }

Handling click events
    @Override
    public void onClick(View v) {
        if (v == viewholderOtions) {

int position = (int) v.getTag();

showPopupMenu(viewholderOtions, position);
        }

}
}

public class NativeExpressAdViewHolder extends RecyclerView.ViewHolder {
    NativeExpressAdViewHolder(View view) {
        super(view);
    }
}

public MainActivityVideoAdapter(Context context, ArrayList<PathModel> ThumbPathList, ArrayList<PathModel> VideoPathList) {
    this.context = context;
    this. ThumbPathList = ThumbPathList;
    this. VideoPathList = VideoPathList;
}

public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    switch (viewType) {
        case AD_VIEW_TYPE:
            View nativeExpressLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.native_express_add_container, parent, false);
            return new NativeExpressAdViewHolder(nativeExpressLayoutView);
        case MENU_ITEM_VIEW_TYPE:
        default:
            View myLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list, parent, false);
            return new ViewHolder(myLayoutView);
    }
}

public void onBindViewHolder(final ViewHolder myHolder, final int position) {
    int viewType = getItemViewType(position);
    switch (viewType) {
        case AD_VIEW_TYPE:

case MENU_ITEM_VIEW_TYPE:
        default:

final PathModel videoPathModel = this. VideoPathList.get(position);
            PathModel thumbathModel = this. ThumbPathList.get(position);
            File file = new File(videoPathModel.getPath());
            String filename = file.getName();
            myHolder.videoName.setText(filename);
            myHolder.videoThumb.setImageURI(Uri.parse(thumbathModel.getPath()));
            myHolder.viewholderOtions.setTag(position);

myHolder.itemView.setOnClickListener(new View.OnClickListener() {

@Override
                public void onClick(View v) {                
                Intent intent= new Intent(context, VideoPlayerActivity.class);              
                intent.putExtra("fromFA2", "fromFA2");
                context.startActivity(intent);

}

});

}

}

Hello@ClassA I found that you have been importing local classes instead of RecyclerView.ViewHolder in onBindViewHolder().

Take a look at the code below, which may help you.

public class MainActivityVideoAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

/*
------------------
your constructor goes here
-----------------
*/

@Override
    public int getItemCount() {
        return 0;
    }

public void onBindViewHolder(final RecyclerView.ViewHolder myHolder, final int position) {
        int viewType = getItemViewType(position);
        switch (viewType) {
            case AD_VIEW_TYPE:
            break;

case MENU_ITEM_VIEW_TYPE:
            break;
        }
    }

public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        switch (viewType) {
            case AD_VIEW_TYPE:
                View nativeExpressLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.native_express_add_container, parent, false);
                return new NativeExpressAdViewHolder(nativeExpressLayoutView);
            case MENU_ITEM_VIEW_TYPE:
                View myLayoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list, parent, false);
                return new ViewHolder(myLayoutView);
        }
    }

class ViewHolder extends RecyclerView.ViewHolder  {

ViewHolder(View itemView) {
            super(itemView);
        }
    }

public class NativeExpressAdViewHolder extends RecyclerView.ViewHolder {
        NativeExpressAdViewHolder(View view) {
            super(view);
        }
    }
}

This code does not contain your variables and logic, this code is used for perfect import and usage methods.

If this solves your problem, approve this answer.
Happy coding.
