我正在使用CardView创建带通讯的卡片列表。基本元素是3个TextViews + 1 ImageView。我不能正确膨胀2个元素：标题是好的，但链接文本获取错误的字符串（它获取字符串引用正文）和正文TextView根本不会改变。RecyclerView + CardView：给错误的数据填充
AERES与一般IDEIA图片：

这是我CardView XML代码：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context=".News">
<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card1_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
card_view:cardCornerRadius="4dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/news_title"
android:layout_width="match_parent"
android:layout_height="40dp"
android:paddingLeft="8dp"
android:text="articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle articleTitle "
android:textColor="#000000"
android:textSize="16sp"
android:textStyle="bold" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="150dp"
android:orientation="horizontal">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="6"
android:orientation="vertical">
<TextView
android:id="@+id/news_link"
android:layout_width="match_parent"
android:layout_height="25dp"
android:gravity="center_vertical"
android:paddingLeft="8dp"
android:text="http://www.articleLink.com/" />
<TextView
android:id="@+id/news_body"
android:layout_width="match_parent"
android:layout_height="120dp"
android:paddingLeft="8dp"
android:text="Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body Body ..."
android:textColor="#000000" />
</LinearLayout>
<ImageView
android:id="@+id/news_photoId"
android:layout_width="0dp"
android:layout_height="145dp"
android:layout_weight="5"
android:src="@drawable/enfnotum" />
</LinearLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="20dp"
android:gravity="end"
android:paddingEnd="6dp"
android:paddingRight="6dp"
android:text="Coments Share" />
<TextView
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#bab7b7" />
</LinearLayout>
</android.support.v7.widget.CardView>
RecycleView列表布局XML代码：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".News">
<android.support.v7.widget.RecyclerView
android:id="@+id/rv"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
现在的Java类： 这里IM填充列表，呼叫转接
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);
}
}
我CLASSE创建列表对象，几个干将
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;
}
}
充气布局
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);
}
}
}
我不能相信...太多了 – RCO
