布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:background="#000000"><Button android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/btn"android:text="Hello!"/>
</LinearLayout>

代码：   使用handler的postDelayed方法每半秒钟发送一个消息来执行动画效果，同时在handler里面使动画平移的距离缩短，当距离为零时就通过handler的 removeCallbacks方法取消runnable正在执行的操作！ 每一次点击按钮都重置一下动画的距离，并且开启runnable，执行操作！
