私はCardViewを使ってニュースレターを持つカードのリストを作成しています。基本的な要素は3 TextViews + 1 ImageViewです。私は2つの要素を適切に膨張させることはできません：タイトルは問題ありませんが、リンクテキストは間違った文字列を取得します（ボディテキストを参照する文字列を取得します）。RecyclerView + CardView：間違ったデータを膨張させる

これは私のCardViewのXMLコードであります今
Javaクラス：ここ イムアダプタレイアウト
を膨らまpublic class News extends AppCompatActivity {
private List<Article> articles = new ArrayList<>();
private RecyclerView rv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_news);
rv = (RecyclerView) findViewById(R.id.rv);
LinearLayoutManager llm = new LinearLayoutManager(this);
rv.setLayoutManager(llm);
initializeData();
initializeAdapter();
}
private void initializeData() {
articles.add(new Article("0title", "0link", "0body", R.drawable.enfnotum));
articles.add(new Article("1title", "1link", "1body", R.drawable.enfnoticias));
articles.add(new Article("2title", "2link", "2body", R.drawable.image1));
articles.add(new Article("3title", "3link", "3body", R.drawable.image2));
articles.add(new Article("4title", "4link", "4body", R.drawable.image3));
articles.add(new Article("5title", "5link", "5body", R.drawable.enfnotum));
articles.add(new Article("6title", "6link", "6body", R.drawable.image3));
articles.add(new Article("7title", "7link", "7body", R.drawable.enfnoticias));
//TODO: database
}
private void initializeAdapter() {
NewsRVAdapter adapter = new NewsRVAdapter(articles);
rv.setAdapter(adapter);
}
}
リストオブジェクトを作成するために、私クラッセ、いくつかのゲッター
public class Article {
private String articleTitle;
private String articleLink;
private String articleBody;
private int articlePhotoId;
public Article(String articleTitle, String articleLink, String articleBody, int articlePhotoId) {
this.articleTitle = articleTitle;
this.articleLink = articleLink;
this.articleBody = articleBody;
this.articlePhotoId = articlePhotoId;
}
public String getArticleTitle() {
return articleTitle;
}
public String getArticleLink() {
return articleLink;
}
public String getArticleBody() {
return articleBody;
}
public int getArticlePhotoId() {
return articlePhotoId;
}
}
呼び出して、リストを取り込みます
public class NewsRVAdapter extends RecyclerView.Adapter<NewsRVAdapter.ArticleViewHolder> {
List<Article> articles;
NewsRVAdapter(List<Article> articles) {
this.articles = articles;
}
@Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
@Override
public ArticleViewHolder onCreateViewHolder(ViewGroup viewGroup, int position) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.news_item_list, viewGroup, false);
return new ArticleViewHolder(v);
}
@Override
public void onBindViewHolder(ArticleViewHolder ArticleViewHolder, int position) {
ArticleViewHolder.articleTitle.setText(articles.get(position).getArticleTitle());
ArticleViewHolder.articleLink.setText(articles.get(position).getArticleLink());
ArticleViewHolder.articleLink.setText(articles.get(position).getArticleBody());
ArticleViewHolder.articlePhotoID.setImageResource(articles.get(position).getArticlePhotoId());
}
@Override
public int getItemCount() {
return articles.size();
}
public static class ArticleViewHolder extends RecyclerView.ViewHolder {
CardView cv;
TextView articleTitle;
TextView articleLink;
TextView articleBody;
ImageView articlePhotoID;
ArticleViewHolder(View itemView) {
super(itemView);
cv = (CardView) itemView.findViewById(R.id.card1_view);
articleTitle = (TextView) itemView.findViewById(R.id.news_title);
articleLink = (TextView) itemView.findViewById(R.id.news_link);
articleBody = (TextView) itemView.findViewById(R.id.news_body);
articlePhotoID = (ImageView) itemView.findViewById(R.id.news_photoId);
}
}
}
私は大嫌いです。 – RCO
