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:

  
    android:orientation="vertical" android:layout_width="fill_parent"  
    android:layout_height="fill_parent"  
    >  
            android:id="@+id/viewFlipper1" android:layout_width="fill_parent"  
        >  
                    android:layout_height="wrap_content">  
                            android:layout_height="wrap_content" android:text="第一屏" />  
          
                    android:layout_height="wrap_content">  
                            android:layout_height="wrap_content" android:text="第二屏" />
