1,規劃路徑

LatLonPoint latLonPoint1 = new LatLonPoint(xxx,xxx);

LatLonPoint latLonPoint2 = new LatLonPoint(xxx,xxx);

RouteSearch mRouteSearch = new RouteSearch(this);

mRouteSearch.setRouteSearchListener(this);

final RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(

latLonPoint1, latLonPoint2);

RouteSearch.RideRouteQuery query = new RouteSearch.RideRouteQuery(fromAndTo, RouteSearch.RidingDefault);

mRouteSearch.calculateRideRouteAsyn(query);// 異步路徑規劃騎行模式查詢

2,監聽并得到路徑規劃結果

@Override

public void onBusRouteSearched(BusRouteResult driveRouteResult, int i) {

}

@Override

public void onDriveRouteSearched(DriveRouteResult driveRouteResult, int i) {

}

@Override

public void onWalkRouteSearched(WalkRouteResult walkRouteResult, int i) {

}

@Override

public void onRideRouteSearched(RideRouteResult rideRouteResult, int i) {

RidePath drivePath = rideRouteResult.getPaths().get(0);

RideRouteOverlay drivingRouteOverlay = new RideRouteOverlay(this, aMap, drivePath, rideRouteResult.getStartPos(), rideRouteResult.getTargetPos());//自定義路徑樣式

drivingRouteOverlay.setNodeIconVisibility(false);//隱藏轉彎的節點

drivingRouteOverlay.addToMap();

drivingRouteOverlay.zoomToSpan();

}

3,自定義路徑樣式
