android 布局式跑马灯，非TextView

如题，简单的实现了跑马灯效果，把Scroll.java放入android.view包下，XML使用如下：
<?xml version="1.0" encoding="utf-8"?>
<Scroll xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="100dip"
android:layout_height="wrap_content">
<!--注意：Scroll里的布局或者控件元素只能有一个可以用布局嵌套布局/控件来使用，当Scroll里的唯一元素的宽度超过Scroll效果最好，如果不超过没加处理，有兴趣可以自己加上-->
<TextView android:layout_width="fill_parent"
  android:layout_height="wrap_content" android:text="放大镜流口水附近拉神经分裂卡上的经费里卡迪神经分裂空间爱上" />
</Scroll>
代码如下：

另外提供了一个可以直接跑的附件，不过附件里的只是一个TextView,大家可以把它换上LinearLayout里加上n个TextView看看，前提是LinearLayout要是Horizontal的
