</LinearLayout>

　　lay02.xml，lay03.xml除了最顶端设置的页码不一样，其他都一直，所以之类就不放上其对应的xml了。

lay04:

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

</LinearLayout>
