在列表的点击事件中,先找到设置了标签的控件,即可得到存在其中的数据
lvNews.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View view, int arg2,
long arg3) {
// TODO Auto-generated method stub
News news=null;
TextView tv=(TextView)view.findViewById(R.id.news_listitem_title);
news=(News)tv.getTag();
}
});
