制作适配器：

Making Adapter:

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;
}

项目是滚动。

Items are scrolling.

更新：的ListView 不得在滚动型 XML格式。如果是，则发生相同的问题。

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