安卓高德地图开发自定义线路规划(按着自己定义的经纬度规划线路)
原理在之前的博客已经说明了，这个具体的过程就不多说了，这里我直接贴上代码：
1：设置的经纬度起始点和终点的经纬度；
private LatLonPoint startPoint = new LatLonPoint(34.185642, 108.881905);
private LatLonPoint endPoint = new LatLonPoint(34.214397, 108.963448);
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：34.224136,108.9552842:主代码
