        android:layout_height="fill_parent"

        android:background="#ffffff" />

</LinearLayout>

　　效果图如下：

item.xml:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout

    android:layout_width="match_parent"

	android:layout_height="wrap_content"

    xmlns:android="http://schemas.android.com/apk/res/android">

    <ImageView

        android:id="@+id/itemImage"

        android:layout_height="wrap_content"

        android:layout_width="wrap_content"

        android:src="@drawable/ic_launcher"

        android:layout_alignParentLeft="true"

        />

    <TextView

        android:layout_height="wrap_content"

        android:layout_width="wrap_content"

        android:text="前段时间做了一个与LBS有关的项目"

        android:layout_toRightOf="@+id/itemImage"

        android:layout_centerVertical="true"

        />

</RelativeLayout>

　　lay1.xml:

<?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"

     >

     <TextView

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:text="第一页"

         android:gravity="center"

         />

     <Button

         android:id="@+id/confirm"

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_marginLeft="2dp"

         android:layout_marginRight="2dp"

         android:text="确定"

         />

     <Button

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_marginLeft="2dp"

         android:layout_marginRight="2dp"

         android:text="分享"

         />

     <Button

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_marginLeft="2dp"

         android:layout_marginRight="2dp"

         android:text="浏览"

         />

     <Button

         android:layout_width="match_parent"

         android:layout_height="wrap_content"

         android:layout_marginLeft="2dp"

         android:layout_marginRight="2dp"

         android:text="取消"

         />

</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>
