Showing Ads in Recycler View

Question

I am working with Recycler View in which i have to show two items in GridLayout Manager and span count of 2.

GridLayoutManager gridLayoutManager;

gridLayoutManager = new GridLayoutManager(getActivity(), 2);

newsRecycler.setLayoutManager(gridLayoutManager);

The main problem is that i have to show Ads after four items (i.e. 2 rows) that will cover width of mobile.But due to Span count the ads are also coming in Grid layout.Any help would be appreciated !!.

Output is coming like this:-

Expected Output:--

Adapter Class :-

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



private List<HomeNewsDataModel> homeNewsDataModels;

public NewsAdapter(FragmentActivity activity, List<HomeNewsDataModel> homeNewsDataModels) {
    this.activity = activity;
    this.homeNewsDataModels=homeNewsDataModels;

}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {

    View v = null;



        v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.news_item_layout, viewGroup, false);
        return new ContentViewHolder(v);
    }


}

private final int  CONTENT_TYPE=1;

private final int AD_TYPE=2;

@Override
public int getItemViewType(int position)
{
    if (position % 4 == 0)
        return AD_TYPE;
    return CONTENT_TYPE;
}


class ViewHolder extends RecyclerView.ViewHolder {

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


    }


}

class ContentViewHolder extends ViewHolder {



    @BindView(R.id.news_item)
    LinearLayout newsItem;

    @BindView(R.id.news_image)
    ImageView newsImage;

    @BindView(R.id.tv_title)
    TextView tvTitle;


    @BindView(R.id.play_video_bt)
    Button playVideoBt;

    @BindView(R.id.news_main)
    LinearLayout news_main;




    public ContentViewHolder(View itemView) {
        super(itemView);
        ButterKnife.bind(this, itemView);


    }




}

class ADViewHolder extends ViewHolder {



    @BindView(R.id.ad_item)
    LinearLayout ad_item;

    @BindView(R.id.ad_image_image)
    ImageView ad_image_image;




    public ADViewHolder(View itemView) {
        super(itemView);
        ButterKnife.bind(this, itemView);


    }

    private void bindData() {






    }



}

@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {


}


@Override
public int getItemCount() {
    return homeNewsDataModels.size();
}

Answer 1

Ok, so I finally found a solution. What I was doing wrong was putting the wrong condition and not inflating the right layout - ads_layout.

Here is the final Adapter Class. The rest is the same. Changes made in onCreateViewHolder, inflating ad layout at position 5 after every 4 items.

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {

        View v = null;

        if (viewType == CONTENT_TYPE) {    
            v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.news_item_layout, viewGroup, false);
            return new ContentViewHolder(v);
        } else {
            v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.ad_layout, viewGroup, false);
            return new ADViewHolder(v);
        }
    }

and some changes in the following function:

    @Override
    public int getItemViewType(int position) {
        if ((position+1) % 5 == 0 && (position+1) != 1) {
            return AD_TYPE;
        }
        return CONTENT_TYPE;
    }

Hope it might help someone in the future. Thanks.
