那一刻 我升起风马 不为乞福 只为守候你的到来
那一天 闭目在经殿香雾中 蓦然听见 你颂经中的真言
那一日 垒起玛尼堆 不为修德 只为投下心湖的石子
那一夜 我听了一宿梵唱 不为参悟 只为寻你的一丝气息
我陆续出过一些

我主要讲解下红字注释的地方，为什么自定义一个View在布局时将其大小设为wrap_content但其实际却是match_parent的效果？请查阅谷歌的小弟一自定义View系列教程02–onMeasure源码详尽分析；处理
在此非常感谢ldoublem 的效果图并通过代码实现了出来，我们实现过程有很多不同的地方。

概述
有时候我会为了实现某个动画的算法而绞尽脑汁，苦苦思考。往往会在草稿上面绘制动画轨迹，真的很多时候几天就在纠结一个动画的实现，不过最后成功后真的很满足喜悦。我陆续出过一些
LodingView的文章，但都比较杂乱。近来我在网上看到一张图，并通过代码实现了出来。在这边非常感谢
@ldoublem，我会不断更新
LodingView把好看及简洁的动画集成进来，希望能够帮助到你。

padding情况，不然布局
xml文件设置
padding值将无效；绘制过程比较简单，我这里就不再详细讲解，有不懂请给我留言。

WSCircleSun主要是控制小圆的旋转，每次移动角度就增加moveAngle。

WSFiveStar主要控制线条的绘制，一条直线从起点绘制到终点，终点作为下一条直线的起点，依次绘制。利用mPath.rLineTo增量的方式绘制直线，如果你敢兴趣可以通过设置
setRegularPolygon(int regularPolygon)方法设置需要绘制的是正多边形，我绘制出过正二十四边形。
