我有几个需要解析的RSS源，我按照这里的优秀教程进行了操作：http://w2davids.wordpress.com/android-rssatom-feeds-parsing-with-rome/. 我稍微修改了示例并使其达到了我所需的效果。所以，我想将其集成到我的应用程序中，但每次尝试显示帖子列表时都会出现Force Quit。我的修改版本代码如下。它似乎总是在将适配器附加到ListView时失败，因此我认为我的适配器设置不正确。奇怪的是，在调试器中，我可以查看适配器并看到我正在尝试获取的数据。
提前感谢您的帮助：
public class View1 extends Activity
{
/** Called when the activity is first created. */
private final ArrayList<String> list = new ArrayList<String>();
private ListView listView;
private ArrayAdapter<String> adapter = null;
private SyndContent desc;
private ArrayList<String> d = new ArrayList<String>() ;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
adapter = new ArrayAdapter<String>(this, R.layout.dataview, R.id.ListItemView);
getRSS("http://www.example.com/wp/?feed=gigpress&artist=1");
listView.setAdapter(adapter);
listView = (ListView) this.findViewById(R.id.ListView);
listView.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long duration)
{
Intent intent = new Intent();
intent.setClassName("com.example.idtb", "com.example.idtb.ViewRssDescription");
intent.putExtra("desc", d.get(position));
startActivity(intent);
}
});
}
private void getRSS(String rss)
{

{

}
