2.SVG-Path路径
下面的命令可用于路径数据：
M = moveto
L = lineto
H = horizontal lineto
V = vertical lineto
C = curveto
S = smooth curveto
Q = quadratic Belzier curve
T = smooth quadratic Belzier curveto
A = elliptical Arc
Z = closepath
注释：以上所有命令均允许小写字母。大写表示绝对定位，小写表示相对定位。请把下面的代码拷贝到记事本，然后把文件保存为 "path1.svg"。把此文件放入您的 web 目录：
<?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg width="100%" height="100%" version="1.1" xmlns="http://www.w3.org/2000/svg"> <path d="M250 150 L150 350 L350 350 Z" /> </svg>上面的例子定义了一条路径，它开始于位置 250 150，到达位置 150 350，然后从那里开始到 350 350，最后在 250 150 关闭路径。
3.图片生成SVG格式
这里推荐使用GIMP工具生成，具体步骤如下：
根据以上找到Path路径，将其保存起来
再到路径对话框中，将path导出

4.实现方式
这里使用AndroidFillableLoaders框架加载svg，更多可以查看作者文章http://jorgecastillo.xyz/2015/08/16/android-fillable-loaders/
