});
bikingSearch obtains the planned cycling route, listens and draws the route through setOnGetRoutePlanResultListener, and draws it on the map through mBikingRouteOverlay.addToMap();.
By clicking addToMap() (ctrl+mouse click)
源码：
/**
* 添加骑行路线到地图中。
*/
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();
}
}
/**
* 初始化线段属性
*/
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());
}
You can see mPolylineOptions.color, setCustomTexture and width to control the color, shape and width of the route
The final solution is to rewrite BikingRouteOverlay. The specific code is as follows:
