Android 使用ViewFlipper实现左右手势切换页面的demo

废话少说，直接上代码吧
main.xml:

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

    >  
    <ViewFlipper android:layout_height="wrap_content"  
        android:id="@+id/viewFlipper1" android:layout_width="fill_parent"  
        >  
        <LinearLayout android:layout_width="wrap_content"  
            android:layout_height="wrap_content">  
            <TextView android:layout_width="wrap_content"  
                android:layout_height="wrap_content" android:text="第一屏" />  
        </LinearLayout>  
        <LinearLayout android:layout_width="wrap_content"
