与RecyclerView一起使用时,毕加索图像错位问题

Question

在我的应用程序中,我正在展示从Web服务中获取的文章.那些文章有标题,图像和其他领域.为了显示图像,我正在使用毕加索.

问题 - 在滚动RecyclerView时,我看到图像放错了位置.有些项目有重复的图像.我知道它是RecyclerView重用xml项目布局,因此它产生了一个问题.但我认为必须解决这个问题.我已经google了这个,并在stackoverflow上发现了一些帖子,但这没有帮助.例如-

毕加索将图片加载到列表适配器中的错误图像视图中

我尝试过以下但有同样的问题 -

public class ArticleAdapter extends RecyclerView.Adapter<ArticleAdapter.ArticleViewHolder> {

    protected Activity mActivity;
    protected List<Article> mItems = new ArrayList<>();
    private static OnEntityClickCallback mCallback;

    public ArticleAdapter(Activity pActivity) {
        mActivity = pActivity;
    }

    public void setItemClickCallback(OnEntityClickCallback pCallback) {
        this.mCallback = pCallback;
    }

    @Override
public ArticleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View articleView = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_article_item, parent, false);
    return new ArticleViewHolder(articleView);
}

    public void addItem(List<Article> moreItems) {
        mItems.addAll(moreItems);
        notifyDataSetChanged();
    }

    public void removeItems(){
        mItems.clear();
        notifyDataSetChanged();
    }


    @Override
    public void onBindViewHolder(ArticleViewHolder holder, int position) {
        holder.bind(mItems.get(position));
    }

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


    static class ArticleViewHolder extends RecyclerView.ViewHolder {

        private TextView tvTitle;
        TextView tvAuthor;
        TextView tvPostdate;
        ImageView imgImage;
        RatingBar ratingBar;

        public ArticleViewHolder(View view) {
            super(view);
            this.tvTitle = (TextView) view.findViewById(R.id.tv_title);
            this.tvAuthor = (TextView) view.findViewById(R.id.tv_author);
            this.tvPostdate = (TextView) view.findViewById(R.id.tv_date);
            this.imgImage = (ImageView) view.findViewById(R.id.img_image);
            this.ratingBar = (RatingBar) view.findViewById(R.id.ratingBar);
        }

       public void bind(final Article article) {

        tvTitle.setText(article.getTitle());
        tvPostdate.setText(article.getPostdate());
        tvAuthor.setText(article.getAuthor());

        // Canceling the older request
        Picasso.with(imgImage.getContext()).cancelRequest(imgImage);
         // Creating a new request.
        if (article.getImage() != null) {
                Picasso.with(imgImage.getContext()).load(article.getImageUrl())
                .placeholder(R.drawable.noimage)
                .error(R.drawable.noimage)
                .into(imgImage);
        }

    this.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mCallback != null)
                mCallback.onEntitySelected(article);
        }
    });
}

    }
}

更新 - 我的布局文件的一部分

 <ImageView
                    android:id="@+id/img_image"
                    android:layout_width="match_parent"
                    android:layout_height="@dimen/cardview_image_thumbnail_height"
                    android:layout_alignParentStart="true"
                    android:layout_alignParentLeft="true"
                    android:scaleType="centerCrop"
                    android:layout_margin="@dimen/cardview_padding_btw_widgets"
                    android:src="@drawable/noimage"
                    />

任何帮助,将不胜感激.谢谢.

外部设置drawable,因为你正在获得已经附加了一些drawable的imageview.Imageview没有重新创建,因此ImageView中的上一个图像将被删除,直到您将其删除.

    if (article.getImage() != null) {
            Picasso.with(imgImage.getContext()).load(article.getImageUrl())
                    .placeholder(R.drawable.noimage)
                    .error(R.drawable.noimage)
                    .into(imgImage);
    }else{
//         imgImage.setImageDrawable(null);
         imgImage.setImageDrawable(R.drawable.some_drawable);
    }
