先上效果图：
如图，可实现设置：总流程数、已完进度程数、已完成颜色、各个流程点击事件，各个标题
github地址戳这里
使用方法
1.导入compile 'com.github.pavlospt:circleview:1.3'依赖包（因为用到了CircleView）
2.直接把下面两个文件一个java一个xml，复制粘贴进项目（代码放在了文章最后，暂时还没弄成开源库，有时间直接做成依赖包倒进去）
- 在xml中写入ProcessImg控件
- 在java文件中实例化ProcessImg对象
- 根据需要调用几个方法
1.对象.setColor( int color )
设置已完成的进度的颜色，传入颜色的整型值
2.对象.setProcess( int total , int process )
设置总流程数和已完成进度数，第一个参数为总流程数（1~6，因为超过6个堆在一排很难看），第二个为已完成数，均为整型变量
3.对象.setTitle( int position , String text )
设置各流程的标题，第一个参数为标题对应的流程数（1~total），第二个参数为String格式标题文本
**4.对象.setClick( int position , Click click ) **
设置各流程的点击事件，第一个参数是点击的流程（1~total），第二个参数为点击后的回调方法。
