android新手关于左右滑动的问题，布局把<android.support.v4.view.ViewPager/><ImageView/> 放在上面就不行了。

============问题描述============

main.xml代码：

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

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

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

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

<LinearLayout

android:id="@+id/linearLayout1"

android:layout_width="fill_parent"

android:layout_height="100.0dip"

android:background="#FFFFFF" >

<TextView

android:id="@+id/text1"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:layout_weight="1.0"

android:gravity="center"

android:text="页卡1"

android:textColor="#000000"

android:textSize="22.0dip" />

<TextView

android:id="@+id/text2"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:layout_weight="1.0"

android:gravity="center"

android:text="页卡2"

android:textColor="#000000"

android:textSize="22.0dip" />

<TextView

android:id="@+id/text3"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:layout_weight="1.0"

android:gravity="center"

android:text="页卡3"

android:textColor="#000000"

android:textSize="22.0dip" />

</LinearLayout>

<ImageView

android:id="@+id/cursor"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:scaleType="matrix"

android:src="@drawable/a" />

<android.support.v4.view.ViewPager

android:id="@+id/vPager"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center"

android:layout_weight="1.0"

android:background="#000000"

android:flipInterval="30"

android:persistentDrawingCache="animation" />

</LinearLayout>

lay1.xml代码：

<?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"

android:background="#158684" >

<Button android:id="@+id/lay1_button"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="lay1的按钮"/>

</LinearLayout>

lay2.xml代码与lay3.xml代码和lay1代码差不多

activity代码：

============解决方案1============

代码太多不想看。。帮你顶一下吧。。
