源码框架如下：

MainActivity.java:

 1 package com.example.listviewdemo;
 2
 3 import android.os.Bundle;
 4 import android.app.Activity;
 5 import android.app.ListActivity;
 6 import android.content.Intent;
 7 import android.view.Menu;
 8 import android.view.View;
 9 import android.widget.AdapterView.OnItemClickListener;
10 import android.widget.ArrayAdapter;
11 import android.widget.ListAdapter;
12 import android.widget.ListView;
13 import android.widget.TextView;
14 import android.widget.Toast;
15
16 public class MainActivity extends ListActivity {
17     private TextView textView;
18     private String[] items = {"item1","item2","item3","item4","item5","item6"};
19     @Override
20     protected void onCreate(Bundle savedInstanceState) {
21         super.onCreate(savedInstanceState);
22         setContentView(R.layout.activity_main);
23         textView = (TextView) findViewById(R.id.TextView);
24         setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
25                 items));
26     }
27
28     @Override
29     protected void onListItemClick(ListView l, View v, int position, long id) {
30         // TODO Auto-generated method stub
31         super.onListItemClick(l, v, position, id);
32
33         textView.setText(items[position]);
34         Toast.makeText(this, position+"", Toast.LENGTH_LONG).show();
35         switch (position) {
36         case 0:
37             Intent intent = new Intent();
38             intent.setClass(this, TabDemo.class);
39             startActivity(intent);
40             break;
41
42         default:
43             break;
44         }
45
46     }
47
48     @Override
49     public boolean onCreateOptionsMenu(Menu menu) {
50         // Inflate the menu; this adds items to the action bar if it is present.
51         getMenuInflater().inflate(R.menu.main, menu);
52         return true;
53     }
54
55 }

TabDemo.java:

package com.example.listviewdemo;

import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.TabHost;

public class TabDemo extends TabActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        TabHost tabHost = getTabHost();
    //    LayoutInflater.from(this).inflate(R.layout.tab1,
    //            tabHost.getTabContentView(),true);

        LayoutInflater.from(this).inflate(R.layout.tab2,
                tabHost.getTabContentView(),true);
        tabHost.addTab(tabHost.newTabSpec("TAB1").setIndicator("布局1")
                .setContent(new Intent(this,Tab1.class)));
        tabHost.addTab(tabHost.newTabSpec("TAB2").setIndicator("布局2")
                .setContent(R.id.tab2));
        }
}

tab1.java

package com.example.listviewdemo;

import android.app.Activity;
import android.os.Bundle;

public class Tab1 extends Activity{

@Override
    protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tab1);
    }
}
