findViewById(R.id.list)没有解析?

我收到以下错误消息: R.id.list无法解析。

我正在扩展ListActivity,在布局中我有ListView android:id =“@ android:id / list”

    public class Results extends ListActivity {
    static final String TAG = "Results";
    ListView m_lv;
    List<Map<String, String>> m_dataList = null;

    ListView lv;
    SimpleAdapter m_adapter;
    ProgressDialog m_dialog;
    AsyncTask<String, String, String> bg;
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.listviewparent);
    lv = (ListView) findViewById(R.id.list);
    lv = getListView();

下面是listviewparent.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
    <LinearLayout style="@style/TitleBar">
        <ImageButton style="@style/TitleBarAction"
            android:contentDescription="@string/description_home"
            android:src="@drawable/title_home"
            android:onClick="onClickHome" />
        <ImageView style="@style/TitleBarSeparator" />
        <TextView style="@style/TitleBarText" />
        <ImageButton style="@style/TitleBarAction"
            android:contentDescription="@string/description_about"
            android:src="@drawable/title_about"
            android:onClick="onClickAbout" />
        <ImageButton style="@style/TitleBarAction"
            android:contentDescription="@string/description_search"
            android:src="@drawable/title_search"
            android:onClick="onClickSearch" />
    </LinearLayout>
 <ListView android:id="@android:id/list"
        android:layout_width="fill_parent" android:layout_weight="1" android:layout_height="0px"/>   
</LinearLayout>

有什么想法吗?

提前致谢。

对于R.id.list,名称空间必须为android.R,但对于您的查看父级,您的R是您的程序名称空间之一。只需将android.添加到R.id.list的开头即可修复命名空间。

使用此:

findViewById(android.R.id.list)
