请原谅我，我是新人：这方面的新手。我使用 asimple_list_item_2来显示 11 个项目。这 11 个项目是使用HashMapthen加载的SimpleAdapter。这在显示所有内容时效果很好。问题是我不能继续setOnItemClickListener 前进。编码：

public class TwoLineActivity extends ListActivity 
{

ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>(2);

@Override
public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.scrolllist); 

        // enter valid data, these 2 are the same as the remaining 9
        HashMap<String, String> maplist;
        maplist = new HashMap<String, String>();
        maplist.put("line1", "a11 data");
        maplist.put("line2", "asd asd ad 1234569780");
        list.add(maplist);

        maplist = new HashMap<String, String>();  
        maplist.put("line1", "a12 data");
        maplist.put("line2", "asd asd ad 1234569781");
        list.add(maplist);

String[] from = { "line1", "line2" };

int[] to = { android.R.id.text1, android.R.id.text2 };

SimpleAdapter adapter = new SimpleAdapter(this, list, android.R.layout.simple_list_item_2, from, to);  
setListAdapter(adapter);`

所以到这里为止，一切都很好，我得到了我的清单。现在我希望能够从列表中选择一个项目，所以我编写了接下来的 2 行

    list.setAdapter(adapter);  
    list.setOnItemClickListener(new OnItemClickListener()
    { .....

我收到以下错误

The method setAdapter(SimpleAdapter) is undefined for the type ArrayList<HashMap<String,String>>

和

The method setOnItemClickListener(new AdapterView.OnItemClickListener(){}) is undefined for the type ArrayList<HashMap<String,String>>

如果您的活动扩展了 ListActivity，您应该覆盖

protected void onListItemClick(ListView l, View v, int position, long id) {

}
