/**
* 一个FloatingActionButton有一个FloatingActionMenu，FloatingActionMenu添加动画弹出的子菜单。
* FloatingActionButton的按钮点击事件将触发、弹出FloatingActionMenu中包含的子菜单。
* FloatingActionMenu使用attachTo方法附着在一个FloatingActionButton上。
* FloatingActionMenu在attachTo到一个FloatingActionButton后，两者之间发生关联。
* FloatingActionMenu在添加子菜单时候，首先需要一个SubActionButton.Builder，该SubActionButton.
* Builder通过setContentView(ImageView
* image).build()把一个ImageView创建生产一个SubActionButton ,
* 然后通过FloatingActionMenu.Builder的add方法把前面生成的SubActionButton添加进去。
*
* 按钮的旋转动画在onMenuOpened和onMenuClosed中做。
