bikingSearch獲取騎行規劃的路線，并通過setOnGetRoutePlanResultListener進行監聽繪制路線，通過mBikingRouteOverlay.addToMap();繪制到地圖上。
通過點擊addToMap()（ctrl+鼠標點擊）

源碼：/*** 添加騎行路線到地圖中。*/public void addToMap() {initPolylineOptions();try {List<RideStep> ridePaths = ridePath.getSteps();for (int i = 0; i < ridePaths.size(); i++) {RideStep rideStep = ridePaths.get(i);LatLng latLng = AMapUtil.convertToLatLng(rideStep.getPolyline().get(0));addRideStationMarkers(rideStep, latLng);addRidePolyLines(rideStep);}addStartAndEndMarker();showPolyline();} catch (Throwable e) {e.printStackTrace();}}/*** 初始化線段屬性*/private void initPolylineOptions() {if(walkStationDescriptor == null) {walkStationDescriptor = BitmapDescriptorFactory.fromResource(R.drawable.amap_ride);}mPolylineOptions = null;mPolylineOptions = new PolylineOptions(); // mPolylineOptions.color(getDriveColor()).width(getRouteWidth());// mPolylineOptions.color(getWalkColor()).width(getRouteWidth());mPolylineOptions.color(getDriveColor()).setCustomTexture(BitmapDescriptorFactory.fromResource(R.drawable.map_alr)).width(getRouteWidth());}

可以看到mPolylineOptions.color、setCustomTexture和width來控制路線的顏色、形狀和寬度

最終解決方式為重寫BikingRouteOverlay，具體代碼如下：
