最近接到了一个新需求 计划做路线导航提示 由于个性化程度很高 与元地图差异较大 我选择了自定义地图和路线规划相机和的方式
先看效果图
首先要点 基本地图显示 定位蓝点 路线规划 自定义路线规划图层（高德已开源） 自定义marker 测距等 功能部分官方网的文档并不是很清晰 我在这里整理一下 我所用的流程
第一 先配置高德环境 自己去高德官网看 按文档来就可以了
第二 初始化地图
map_view = (MapView) findViewById(R.id.map_view);
map_view.onCreate(savedInstanceState);
if (map_view!=null){
aMap = map_view.getMap();
}
设置定位蓝点
MyLocationStyle myLocationStyle;
myLocationStyle = new MyLocationStyle();//初始化定位蓝点样式类myLocationStyle.myLocationType(MyLocationStyle.LOCATION_TYPE_LOCATION_ROTATE);//连续定位、且将视角移动到地图中心点，定位点依照设备方向旋转，并且会跟随设备移动。（1秒1次定位）如果不设置myLocationType，默认也会执行此种模式。
myLocationStyle.interval(2000); //设置连续定位模式下的定位间隔，只在连续定位模式下生效，单次定位模式下不会生效。单位为毫秒。
aMap.getUiSettings().setMyLocationButtonEnabled(false);//设置默认定位按钮是否显示，非必需设置。
aMap.setMyLocationEnabled(true);// 设置为true表示启动显示定位蓝点，false表示隐藏定位蓝点并不进行定位，默认是false。
// myLocationStyle.myLocationType(MyLocationStyle.LOCATION_TYPE_LOCATION_ROTATE);//连续定位、且将视角移动到地图中心点，定位点依照设备方向旋转，并且会跟随设备移动。（1秒1次定位）默认执行此种模式。
myLocationStyle.myLocationType(MyLocationStyle.LOCATION_TYPE_LOCATION_ROTATE_NO_CENTER);//连续定位、蓝点不会移动到地图中心点，定位点依照设备方向旋转，并且蓝点会跟随设备移动。
myLocationStyle.myLocationIcon(BitmapDescriptorFactory.fromResource(R.mipmap.map_ownerlocation_img));
myLocationStyle.showMyLocation(true);aMap.setMyLocationStyle(myLocationStyle);//设置定位蓝点的Style aMap.setMapType(AMap.MAP_TYPE_NAVI);
模拟地点 并规划路线
////////////////////路线规划////////////////////// start = new LatLonPoint(30.291779,120.040998); end = new LatLonPoint(30.406169,120.305117); final LatLonPoint way1 = new LatLonPoint(30.270999,120.163277); final LatLonPoint way2 = new LatLonPoint(30.291124,120.212892); wayPointList.add(way1); wayPointList.add(way2); routeSearch = new RouteSearch(this); routeSearch.setRouteSearchListener(this); // fromAndTo包含路径规划的起点和终点，drivingMode表示驾车模式 // 第三个参数表示途经点（最多支持16个），第四个参数表示避让区域（最多支持32个），第五个参数表示避让道路 RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(start, end); RouteSearch.DriveRouteQuery query = new RouteSearch.DriveRouteQuery(fromAndTo, RouteSearch.DrivingDefault,wayPointList, null, “”);
routeSearch.calculateDriveRouteAsyn(query);//////////////////当前位置监听////////////////// aMap.setOnMyLocationChangeListener(new AMap.OnMyLocationChangeListener() { @Override public void onMyLocationChange(Location location) { } })
;
自定义路线规划图层 高德sdk 5.0版本以后 就不在提供overlay包 但是官方demo 中会有overlay 包 如有需要你可以直接过去拷贝 有一些小地方需要修改 注意下
@Override
public void onDriveRouteSearched(DriveRouteResult driveRouteResult, int i) {
if (i==1000){// 路线规划成功
if (driveRouteResult!=null&&driveRouteResult.getPaths()!=null&&driveRouteResult.getPaths().size()>0){
DrivePath drivePath = driveRouteResult.getPaths().get(0);
aMap.clear();// 清理地图上的所有覆盖物
// 定义图层
DrivingRouteOverlay drivingRouteOverlay = new DrivingRouteOverlay(MapActivity.this, aMap, drivePath,
driveRouteResult.getStartPos(),
driveRouteResult.getTargetPos(),wayPointList);
drivingRouteOverlay.setNodeIconVisibility(false);//隐藏转弯的节点
drivingRouteOverlay.addToMap();
drivingRouteOverlay.zoomToSpan();
aMap.animateCamera(CameraUpdateFactory.newLatLngBounds(new
LatLngBounds(
new LatLng(start.getLatitude(),start.getLongitude()),
new LatLng(end.getLatitude(),end.getLongitude())),50));} }else {// 路线规划失败 Toast.makeText(MapActivity.this, "无可用路线", Toast.LENGTH_SHORT).show(); } }
