我在另一个论坛上看到了一个代码并将其清理干净了一点.要做你需要的,你必须改变ts1.setContent和ts2.setContent里面的东西

Main_screen.java

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;

public class Main_screen extends Activity{

    private ListView ls1;
    private ListView ls2;   
    private TabHost myTabHost;

    @Override
    public void onCreate(Bundle icicle)
    {
        super.onCreate(icicle);
        setContentView(R.layout.main);

        myTabHost = (TabHost)this.findViewById(R.id.th_set_menu_tabhost); 
        myTabHost.setup();

        ls1 = new ListView(Main_screen.this);       
        TabSpec ts1 = myTabHost.newTabSpec("TAB_TAG_1");
        ts1.setIndicator("Tab1");
        ts1.setContent(new TabHost.TabContentFactory(){
            public View createTabContent(String tag)
            {                                   
                ArrayAdapter<String> adapter = new ArrayAdapter<String>(Main_screen.this,android.R.layout.simple_list_item_1,new String[]{"item1","item2","item3"});
                ls1.setAdapter(adapter);    
                return ls1;
            }       
        });
        myTabHost.addTab(ts1);

        ls2 = new ListView(Main_screen.this);
        TabSpec ts2 = myTabHost.newTabSpec("TAB_TAG_2");
        ts2.setIndicator("Tab2");
        ts2.setContent(new TabHost.TabContentFactory(){
            public View createTabContent(String tag)
            {                                   
                ArrayAdapter<String> adapter = new ArrayAdapter<String>(Main_screen.this,android.R.layout.simple_list_item_1,new String[]{"item4","item5","item6"});
                ls2.setAdapter(adapter);    
                return ls2;
            }       
        });     
        myTabHost.addTab(ts2);
    }       
}

main.xml中

<?xml version="1.0" encoding="utf-8"?> 
    <TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
        android:id="@+id/th_set_menu_tabhost" 
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent">

     <TabWidget 
          android:id="@android:id/tabs" 
          android:layout_width="fill_parent" 
          android:layout_height="64dip" />

     <FrameLayout 
          android:id="@android:id/tabcontent" 
          android:layout_width="fill_parent" 
          android:layout_height="fill_parent"
          android:paddingTop="75dip">  

          <ListView
              android:id = "@+id/danhsach"
              android:layout_width="fill_parent" 
              android:layout_height="fill_parent" />

     </FrameLayout> 
</TabHost>
