安卓高德地图开发（四）——自定义线路规划（根据地点的经纬度规划线路）
一、原理
在高德地图使用的时候，我们在给定起点和终点的时候就可以规划出线路，但是有时候我们需要车按指定的站点进行运行和线路规划，那么，此时的话就必须自己去重新来规
划这个线路，原理也很简单，就是获取到你要经过的那些地方的经纬度（经纬度一定要是准确的经纬度，这里在获取的时候可以通过地理编码去获取），在获取到经纬度之后把数
据传递到线路规划的方法里面，这样就可以完成线路的自定义规划！
二、获取要经过的站点经纬度
1：布局文件
2：java文件

通过以上的方法可以以此获取到各自的经纬度的值：
private LatLonPoint lat_one = new LatLonPoint(34.215748, 108.891869);
private LatLonPoint lat_two = new LatLonPoint(34.233685, 108.900635);
private LatLonPoint lat_three = new LatLonPoint(34.225311, 108.930992);
private LatLonPoint lat_four = new LatLonPoint(34.224136, 108.955284);
// 旺座现代城：34.215748,108.891869
// 亚美大厦:34.233685,108.900635
// 吉祥村:34.225311,108.930992
// 陕西历史博物馆：34.224136,108.955284同时还要拿到起点和终点的经纬度：
private LatLonPoint startPoint = new LatLonPoint(34.185642, 108.881905);
private LatLonPoint endPoint = new LatLonPoint(34.214397, 108.963448);
