Android TextView 跑马灯效果（自定义控件）

方式一：XML控制

xml代码如下：

<TextView android:layout_width="100dip" android:layout_height="wrap_content" android:layout_gravity="center" android:text="走马灯效果的演示" android:singleLine="true" android:ellipsize="marquee" android:focusable="true" android:focusableInTouchMode="true" />

后四行为主要代码

方式二：自定义控件

## 可在一个页面中显示多个跑马灯
