Question

我有一个回收站视图，其中有一些字符串，如0,1,2,3等等，在同一个recyclerview中，我想在每个第三个索引上放置一个像imageview的视图。下面提到的代码工作正常，但问题是imageview从0索引开始，如序列： - Imageview - ＆gt; 0,1,2 ---＆gt; imageview ---＆gt;。在这里，我不想在索引0之前显示图像视图。

代码： -

private Context mContext;
private ArrayList<String> newList;
private static final int CONTENT_TYPE = 0;
private static final int AD_TYPE = 1;

public CMyAdapter(Context context, ArrayList<String> list) {
    this.mContext = context;
    this.newList = list;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    ViewHolder holder = null;
    if (viewType == AD_TYPE) {
        View adView = LayoutInflater.from(parent.getContext()).inflate(R.layout.view2, parent, false);
        holder = new AdViewHolder(adView);
    } else {
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.view1, parent, false);
        holder = new ItemViewHolder(itemView);
    }
    return holder;
}

@Override
public int getItemViewType(int position) {
    if (newList.get(position) == null) {
        return AD_TYPE;
    } else {
        return CONTENT_TYPE;
    }

}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    if (newList.get(position) == null) {
        AdViewHolder adViewHolder = (AdViewHolder) holder;
        adViewHolder.m_dummyImage.setImageResource(R.mipmap.ic_launcher_round);
    } else {
        ItemViewHolder itemViewHolder = (ItemViewHolder) holder;
        itemViewHolder.m_Text.setText(newList.get(position));
    }
}

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

class ViewHolder extends RecyclerView.ViewHolder {
    ViewHolder(View itemView) {
        super(itemView);


    }
}

private class ItemViewHolder extends ViewHolder {
    TextView m_Text;

    ItemViewHolder(View itemView) {
        super(itemView);
        m_Text = (TextView) itemView.findViewById(R.id.textDemo);
    }
}

private class AdViewHolder extends ViewHolder {
    ImageView m_dummyImage;

    AdViewHolder(View v) {
        super(v);
        m_dummyImage = (ImageView) itemView.findViewById(R.id.adImage);
    }
}

适配器的代码： -

self.tblBeerJournal.sectionHeaderHeight = UITableViewAutomaticDimension
self.tblBeerJournal.estimatedSectionHeaderHeight = 160
self.tblBeerJournal.rowHeight = UITableViewAutomaticDimension
self.tblBeerJournal.estimatedRowHeight = UITableViewAutomaticDimension

}

Answer 1

在条件

中添加（i！= 0）

if (i%2==0 && i!=0){
        newList.add(null);
    }

Answer 2

您可以在CMyAdapter上执行此操作

 @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        if (position%3==0) {
           //TODO
        } else {
           //TODO      
        }
    }

Answer 3

vector<string> s;
sort(s.begin(),s.end());

如何在android的每个回收者视图的第3个索引上放置视图？
