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)

代码语言:javascript
复制

然后回到RouteActivity中,找到onDriveRouteSearched方法,里面的代码如下:

代码语言:javascript
复制
	/**
     * 驾车规划路径结果
     *
     * @param driveRouteResult 结果
     * @param code            结果码
     */
    @Override
    public void onDriveRouteSearched(DriveRouteResult driveRouteResult, int code) {
        aMap.clear();// 清理地图上的所有覆盖物
        if (code == AMapException.CODE_AMAP_SUCCESS) {
            if (driveRouteResult != null && driveRouteResult.getPaths() != null) {
                if (driveRouteResult.getPaths().size() > 0) {
                    final DrivePath drivePath = driveRouteResult.getPaths()
                            .get(0);
                    if(drivePath == null) {
                        return;
                    }
                    DrivingRouteOverlay drivingRouteOverlay = new DrivingRouteOverlay(
                            this, aMap, drivePath,
                            driveRouteResult.getStartPos(),
                            driveRouteResult.getTargetPos(), null);
                    drivingRouteOverlay.removeFromMap();
                    drivingRouteOverlay.addToMap();
                    drivingRouteOverlay.zoomToSpan();

                    int dis = (int) drivePath.getDistance();
                    int dur = (int) drivePath.getDuration();
                    String des = MapUtil.getFriendlyTime(dur)+"("+MapUtil.getFriendlyLength(dis)+")";
                    Log.d(TAG, des);
                } else if (driveRouteResult.getPaths() == null) {
                    showMsg("对不起,没有搜索到相关数据!");
                }
            } else {
                showMsg("对不起,没有搜索到相关数据!");
            }
        } else {
            showMsg("错误码;" + code);
        }
    }

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)

代码语言:javascript
复制
