最近的项目中有个比较好的开源的多个分享按钮的自定义视图，感觉比较好，所以就研究了下，写了下来。其实这个demo类似于github上开源项目ArcMenu开源项目，项目下载地址为：https://github.com/daCapricorn/ArcMenu。
实现效果图：
1、点击该按钮，五个按钮飞入屏幕；
2、点击五个按钮其中的一个后，改按钮放到直至消失，其余的按钮变小直至消失。
体验感还是挺好的。
再次点击五个按钮飞出屏幕。
好了，下面上源码吧。比较多，但都是些自定义的空间，看两遍就能看懂啦。。
只有一个布局文件：share_layout：
里面定义了布局和按钮，这些都是自定义的布局或按钮。

下面就是在布局中引用过的自定义布局、自定义按钮：

}
@Override
