仅获取列表视图的最后一项

Question

我已经在 ListFragment 中解析了 XML，它工作正常，但 OnListItemClick 只抛出最后一项，我搜索过但没有找到任何东西符合我的情况。

这是里面 onPostExecute:

        XMLDOMParser parser = new XMLDOMParser();
        InputStream stream = new ByteArrayInputStream(xml.getBytes());
        Document doc = parser.getDocument(stream);

        NodeList nodeList = doc.getElementsByTagName(KEY_ITEM);

        newss = new ArrayList<News>();
        news = null;
        for (int i = 0; i < nodeList.getLength(); i++) {
            news = new News();
            Element e = (Element) nodeList.item(i);
            news.setId(parser.getValue(e, KEY_ID));
            news.setDate(parser.getValue(e, KEY_DATE));
            news.setTitle(parser.getValue(e, KEY_TITLE));
            news.setDescription(parser.getValue(e, KEY_DESC));
            newss.add(news);
        }

        listViewAdapter = new NewsAdapter(getActivity(), newss);
        getListView().setAdapter(listViewAdapter);

        pDialog.dismiss();

OnItemClick 位于同一片段内：

`@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    Toast.makeText(getActivity(), "List: "+news.getId(), Toast.LENGTH_SHORT).show();
    Intent in = new Intent(getActivity(), SingleNewsActivity.class);
    in.putExtra(KEY_ID, news.getId());
    in.putExtra(KEY_DATE, news.getDate());
    in.putExtra(KEY_TITLE, news.getTitle());
    in.putExtra(KEY_DESC, news.getDescription());
    startActivity(in);
}`

我的NewsAdapter:

public class NewsAdapter extends BaseAdapter { Activity context; List<News> newss; public NewsAdapter (Activity context, List<News> newss) { this.context = context; this.newss = newss; }

// private View Holder class
private class ViewHolder {
    TextView tvNewsDate;
    TextView TvNewsTitle;
}

public int getCount() {
    return newss.size();
}

public Object getItem(int position) {
    return newss.get(position);
}

public long getItemId(int position) {
    return newss.indexOf(getItem(position));
}

public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
    LayoutInflater inflater = context.getLayoutInflater();

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.news_item, null);
        holder = new ViewHolder();
        holder.tvNewsDate = (TextView) convertView.findViewById(R.id.tvNewsDate);
        holder.TvNewsTitle = (TextView) convertView.findViewById(R.id.tvNewsTitle);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    News newss = (News) getItem(position);

    holder.tvNewsDate.setText(newss.getDate());
    holder.TvNewsTitle.setText(newss.getTitle());

    return convertView;
}

}`

ImageView 和 setOnClickListner 在我的另一个适配器中有同样的问题：

holder.ivGPS.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Uri gmmIntentUri = Uri.parse("google.navigation:q=" + parkCoordinates); Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri); mapIntent.setPackage("com.google.android.apps.maps"); context.startActivity(mapIntent); } });

谢谢！

请试试新闻 = newss.get(位置) 并在您的 onListItemClick 中使用它可能会起作用..

  `@Override
public void onListItemClick(ListView l, View v, int position, long id) {
  news = newss.get(position)
    Intent in = new Intent(getActivity(), SingleNewsActivity.class);
    in.putExtra(KEY_ID, news.getId());
    in.putExtra(KEY_DATE, news.getDate());
    in.putExtra(KEY_TITLE, news.getTitle());
    in.putExtra(KEY_DESC, news.getDescription());
    startActivity(in);
}`
