android 地图自定义mark，以高德地图为例

配置key等基本操作就不赘述了，一个老弟问了，我就直接贴代码，简单梳理一下，有问题可以留言。

注：
1、你的activity或者fragment用来管理地图的，需要继承AMap.OnCameraChangeListener, AMap.OnMarkerClickListener, AMap.OnMyLocationChangeListener, AMapLocationListener这几个接口。
2、R.layout.view_map_mark 就是你的自定义mark布局
3、R.layout.fragment_local_kot 就是你的地图布局

R.layout.view_map_mark

R.layout.fragment_local_kot
