Android高德地图路线规划，自定义图层（overlay），所有点和线刚好显示在屏幕中心

高德百度地图SDK路线规划包含：步行，公交，驾车，骑车。
搜索的结果是经纬度点信息Latlng(lat,lng)
功能
在地图map中将所有的点连线，并让该线能刚好被当前的地图层级包含，并且当前路线所在位置能刚好在地图中的中心位置。
效果图（以工具路线为例）：

本例以高德地图进行研究（不包含室内）
思路：对高德地图SDK源码进行改进，根据路线的选择进行自定义Overlay和Markers实体工具类
下图是我建立的工程目录

步骤：
在overlay包下建立两个类，用来封装经纬度点和结果信息的处理及返回，如我可以判断路线中的拐点，及每一段路的连线颜色
比如：路线搜索结果路线是在A-B-C-D,四个街道上，其中A-B可能畅通，B-C可能拥挤，连线的颜色就需要不同，B点作为两个街道的拐点处，需要主动的显示showInfoWindow（）

代码如下：
