④ 驾车路线规划
现在来写这个驾车路线规划，步骤还是和前面的差不多，这回你都不用改布局了，加一个值，如下所示
在这里插入图片描述
然后找到startRouteSearch方法，加一个驾车的条件分支
代码语言：javascript复制 case 2://驾车
//构建驾车路线搜索对象 剩余三个参数分别是：途经点、避让区域、避让道路
RouteSearch.DriveRouteQuery driveQuery = new RouteSearch.DriveRouteQuery(fromAndTo, RouteSearch.WalkDefault, null, null, "");
//驾车规划路径计算
routeSearch.calculateDriveRouteAsyn(driveQuery);
break;然后同样要有一个图层。在overlay包下新增DrivingRouteOverlay类，用于在地图上绘制驾车路线图层，代码如下：（SDK中代码）

}

}
} else {

}
}下面运行一下：
在这里插入图片描述
⑤ 公交路线规划
还有一个公交路线规划，公交的规划其实还包括了步行，不过步行是一点点。下面首先是改变里面的值，增加一个出行方式。
在这里插入图片描述
然后找到startRouteSearch方法，增加如下方式：
代码语言：javascript复制 case 3://公交
//构建驾车路线搜索对象 第三个参数表示公交查询城市区号，第四个参数表示是否计算夜班车，0表示不计算,1表示计算
RouteSearch.BusRouteQuery busQuery = new RouteSearch.BusRouteQuery(fromAndTo, RouteSearch.BusLeaseWalk, "0755",0);
//公交规划路径计算
routeSearch.calculateBusRouteAsyn(busQuery);
break;这里注意一点，那就是城市的区号，这里我填的是0755，表示深圳。你可以通过城市区号查询去查看你所在地的城市区号，当然如果你不想去查询也可以，你可以直接用中文来解决，比如把0755改成深圳，也是可以的。如果你觉得这样也比较麻烦的话，那么你可以定义一个成员变量。
代码语言：javascript复制 //城市
private String city;然后在onLocationChanged中赋值。
代码语言：javascript复制 city = aMapLocation.getCity();最后在替换，这样的话就会以你当前所在城市为准。
代码语言：javascript复制 RouteSearch.BusRouteQuery busQuery = new RouteSearch.BusRouteQuery(fromAndTo, RouteSearch.BusLeaseWalk, city, 0);那么下面同样要绘制公交的图层，在overlay包下新建一个BusRouteOverlay类，代码如下：（来源于SDK）
