学习Android Material Design（RecyclerView代替ListView）

public class ItemArticleAdapter extends RecyclerView.Adapter<ItemArticleAdapter.ImageItemArticleViewHolder> {

 //新闻列表
 private List<ItemArticle> articleList;

 //context
 private Context context;

 private LayoutInflater mLayoutInflater;


 public ItemArticleAdapter(Context context,List<ItemArticle> articleList) {
  this.context = context;
  this.articleList = articleList;
  mLayoutInflater = LayoutInflater.from(context);
 }

 @Override
 public ItemArticleAdapter.ImageItemArticleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
  View view = mLayoutInflater.inflate(
    R.layout.item_article_type_1, parent, false);
  return new ImageItemArticleViewHolder(view);
 }

 @Override
 public void onBindViewHolder(ImageItemArticleViewHolder holder, int position) {
  ItemArticle article = articleList.get(position);
  holder.rcvArticlePhoto.setImageURI(Uri.parse(article.getImageUrl()));
  holder.rcvArticleTitle.setText(article.getTitle());
  holder.rcvArticleDate.setText(article.getPublishDate());
  holder.rcvArticleSource.setText(article.getSource());
  //注意这个阅读次数是 int 类型，需要转化为 String 类型
  holder.rcvArticleReadtimes.setText(article.getReadTimes()+"次");
  holder.rcvArticlePreview.setText(article.getPreview());
 }


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

 class ImageItemArticleViewHolder extends RecyclerView.ViewHolder {

  @InjectView(R.id.rcv_article_photo)
  SimpleDraweeView rcvArticlePhoto;
  @InjectView(R.id.rcv_article_title)
  TextView rcvArticleTitle;
  @InjectView(R.id.rcv_article_date)
  TextView rcvArticleDate;
  @InjectView(R.id.rcv_article_source)
  TextView rcvArticleSource;
  @InjectView(R.id.rcv_article_readtimes)
  TextView rcvArticleReadtimes;
  @InjectView(R.id.rcv_article_preview)
  TextView rcvArticlePreview;

  public ImageItemArticleViewHolder(View itemView) {
   super(itemView);
   ButterKnife.inject(this, itemView);
  }
 }

}

3、新闻实体类 javabean
