Android Listview 只显示一项 [英] Android Listview show only one item

问题描述

我有一个 ListView，我在其中更改了行的外观，但 listview 的大小为一行，而不是全屏.

I have a ListView, where i changed appearence of row, but listview have size of one row, instead of fullscreen.

list_item.xml:

list_item.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/textView_news_time"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:textColor="#0082A8" />

    <TextView
        android:id="@+id/textView_news_header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

</LinearLayout>

tab_news.xml:

tab_news.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:orientation="vertical" >

<ListView
    android:id="@+id/list_news"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

 </ListView>

  </LinearLayout>

制作适配器:

public class RSSAdapter extends ArrayAdapter<RSSitem> {
Context context; 
int layoutResourceId;    
ArrayList<RSSitem> data = null;
SimpleDateFormat sdf = new SimpleDateFormat("kk:mm ");
public RSSAdapter(Context context, int layoutResourceId, ArrayList<RSSitem> data) {
    super(context, layoutResourceId, data);
    this.layoutResourceId = layoutResourceId;
    this.context = context;
    this.data = data;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    NewsHolder holder = null;

    if(row == null)
    {
        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
        row = inflater.inflate(layoutResourceId, parent, false);

        holder = new NewsHolder();
        holder.txtTime = (TextView)row.findViewById(R.id.textView_news_time);
        holder.txtNews = (TextView)row.findViewById(R.id.textView_news_header);

        row.setTag(holder);
    }
    else
    {
        holder = (NewsHolder)row.getTag();
    }

    RSSitem item = data.get(position);
    holder.txtTime.setText(sdf.format(item.getPubDate()));
    holder.txtNews.setText(item.getTitle());

    return row;
}

static class NewsHolder
{
    TextView txtTime;
    TextView txtNews;
}

更新:ListView 不得在 xml 中的ScrollView 下.如果是，就会出现同样的问题.

Update:ListView must not be underScrollView in xml. If it is,the same problem occurs.

更新 2 :您可以使用 NestedScrollView
