求救,tabhost ListActivity怎么样合在一起。

想做一个tabhost分两页的界面。在每一页tab page中，放一个ListActivity.要求tab标签在界面的最下端。
tabmain.xml文件内容



<?xml version="1.0" encoding="utf-8"?>  

<TabHost android:id="@+id/maintabhost"   

      android:layout_width="fill_parent"   

      android:layout_height="fill_parent"   

      xmlns:android="http://schemas.android.com/apk/res/android">  

           <RelativeLayout  

          android:id="@+id/relativeLayout1"   

          android:layout_height="match_parent"   

          android:layout_width="wrap_content"  

          android:orientation="vertical">  

            

            <FrameLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@android:id/tabcontent">  

                <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/tab1"></LinearLayout>  

                <LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/tab2"></LinearLayout>   

            </FrameLayout>  

            <TabWidget android:layout_width="fill_parent"   

              android:layout_height="wrap_content"   

              android:id="@android:id/tabs"

              android:layout_alignParentBottom="true"></TabWidget>  

        </RelativeLayout>  

</TabHost>

tabmini.xml文件内容

<?xml version="1.0" encoding="utf-8"?>  

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    

    android:layout_width="fill_parent"  

    android:layout_height="40dp"  

    android:paddingLeft="5dip"  

    android:paddingRight="5dip"  

    android:background="@drawable/icon">    

      

    <TextView android:id="@+id/tab_label"    

        android:layout_width="fill_parent"  

        android:layout_height="wrap_content"  

        android:layout_centerInParent="true"  

        android:gravity="center"  

        android:textColor="#000000"  

        android:textStyle="bold"  

        android:background="@drawable/icon"/>   

</RelativeLayout>

Test1Activity.java文件名

package com.test.t1;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.widget.TabHost;

public class Test1 extends Activity {

	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);



		setContentView(R.layout.tabmain);



		TabHost tabHost = (TabHost) findViewById(R.id.maintabhost);

		tabHost.setup();		



		//tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("p1").setContent(R.id.tab1));

		//tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("p2").setContent(R.id.tab2));



		Intent intent1 = new Intent(this, ListV.class);

		tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("p1").setContent(intent1));

		tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("p2").setContent(intent1));

	}

}

ListV.java文件内容(使用了ListActivity)

package com.test.t1;



import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;



import android.app.ListActivity;

import android.os.Bundle;

import android.widget.SimpleAdapter;



public class ListV  extends ListActivity {



		@Override

		public void onCreate(Bundle savedInstanceState) {

			super.onCreate(savedInstanceState);

			this.getListView().setCacheColorHint(0);

			this.getListView().setBackgroundColor(android.graphics.Color.WHITE);

			SimpleAdapter adapter = new SimpleAdapter(this,getData(),R.layout.main,new String[]{"title","info"}, new int[]{1,2});			

			setListAdapter(adapter);

		}



		private List<Map<String, Object>> getData() {

			List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();



			Map<String, Object> map = new HashMap<String, Object>();

		



			map = new HashMap<String, Object>();

			map.put("title", "L1");

			map.put("info", "1111111111111111111111111111");

			

			list.add(map);



			map = new HashMap<String, Object>();

			map.put("title", "L2");

			map.put("info", "22222222");

			

			list.add(map);



			return list;

		}	

}

从上面的Test1Actitity.java中



//tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("p1").setContent(R.id.tab1));		//tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("p2").setContent(R.id.tab2));

		Intent intent1 = new Intent(this, ListV.class);		tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("p1").setContent(intent1));	tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("p2").setContent(intent1));

使用R.id.tab1这个ListView组件来，是可以正常显示的。
但使用intent1(是一个ListActivity)则会报错。

哪位能告诉一下，应该怎么弄？
