代码如下：

package com.zhangyg.tab.test;

import java.util.ArrayList;
import java.util.List;

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

public class MainActivity extends TabActivity implements
		TabHost.TabContentFactory {
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		TabHost th = getTabHost();
		th.addTab(th.newTabSpec("home").setIndicator("首页").setContent(this));
		th.addTab(th.newTabSpec("@me").setIndicator("@我").setContent(this));
		th.addTab(th.newTabSpec("comment").setIndicator("评论").setContent(this));
		th.addTab(th.newTabSpec("mess").setIndicator("私信").setContent(this));
		th.addTab(th.newTabSpec("write").setIndicator("撰写").setContent(this));
	}

	@Override
	public View createTabContent(String tag) {
		ListView lv = new ListView(this);
		List<String> list = new ArrayList<String>();
		list.add(tag);
		ArrayAdapter adapter = new ArrayAdapter(this,
				android.R.layout.simple_list_item_checked, list);
		lv.setAdapter(adapter);
		return lv;
	}
}
