本文介绍了一个简单的Android应用程序示例，该程序使用TabActivity实现两个视图之间的切换：地图视图和详细信息视图。文章展示了如何设置TabHost、定义TabSpec以及使用Intent进行页面跳转。

这里面有两个方法其实说来还是一样的

public class BS_Main extends TabActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
          TabHost tabHost = getTabHost(); 
    tabHost.addTab(tabHost.newTabSpec("tab1").setContent(R.id.mapview).setIndicator("mapview_name",getResources().getDrawable(R.drawable.map_icon))); 
    tabHost.addTab(tabHost.newTabSpec("tab2").setContent(R.id.anotherview).setIndicator("tab2_name",getResources().getDrawable(R.drawable.anotherview_icon))); 
  } 
}

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

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:id="@android:id/tabcontent"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<mapview tag here with ur map Api key>
<anotherview tag>
</FrameLayout>
