关于tabhost的底部实现，什么都没有显示，求助！
程序代码：实现部分TabHostActivity.java
package com.map;
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.TabHost;
public class TabHostActivity extends TabActivity {
private TabHost tabHost;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabhost);
tabHost = this.getTabHost();
initTabs();
}
private void initTabs() {
tabHost.setup(this.getLocalActivityManager());
// 添加线路规划的tab
tabHost.addTab(tabHost.newTabSpec("tab1")
.setIndicator("线路规划",getResources().getDrawable(R.drawable.tabpic1))
.setContent(new Intent(this, FirstActivity.class)));
// 添加城市名片的tab
tabHost.addTab(tabHost.newTabSpec("tab5")
.setIndicator("城市名片",getResources().getDrawable(R.drawable.tabpic5))
.setContent(new Intent(this, FifthActivity.class)));
}
}
xml布局文件tabhost.xml
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="fill_parent"
android:orientation="vertical" >
