Question

我将MapBox用于我的Android应用程序，我需要修改用于指示当前用户位置和方向的标准蓝色“点”。

我发现这个帖子表明过去的MapBox Android API提供了修改用户位置图标的方法： https://github.com/mapbox/mapbox-android-sdk-legacy/issues/717

线程提到了这些方法：

mapView.getUserLocationOverlay().setDirectionArrowBitmap();
mapView.getUserLocationOverlay().setPersonBitmap();

最新的MapBox Android SDK未显示这些方法。有没有人知道这些方法的替代品或修改用户位置图标的替代方法？

maven存档位于：http://grepcode.com/file/repo1.maven.org/maven2/com.mapbox.mapboxsdk/mapbox-android-sdk/0.7.4/com/mapbox/mapboxsdk/overlay/UserLocationOverlay.java#UserLocationOverlay.setDirectionArrowBitmap%28com.mapbox.mapboxsdk.overlay.Bitmap%29

Answer 1

MapBox回应了澄清这些方法替换的请求，并说：

至于更改自定义标记的位置以显示移动，最好的选择是在需要显示进度时添加和删除标记。根据您需要刷新位置的速度，这种方法可能看起来有点不稳定，但这是目前最好的解决方法。这将通过
完成

MapView.addMarker()

和

MapView.removeAnnotation()

这不是一个理想的解决方案，但它现在应该完成工作。

                                        Markers indicate single locations on the map. You can customize your markers by changing the default color, or replacing the marker icon with a custom image. Info windows can provide additional context to a marker.


                                            MarkerView markerView = new MarkerView(new LatLng(LAT,LONG), customView);

                                            markerViewManager.addMarker(markerView);

                                            mapView.getMapAsync(new OnMapReadyCallback() {
                                                @Override
                                                public void onMapReady(MapboxMap mapboxMap) {

                                                    MarkerViewManager markerViewManager = new MarkerViewManager(mapView, mapboxMap);

                                                }
                                            });

                                            markerViewManager.removeMarker(markerView);

足够多的谈话，让我们看看一些好，我们会检查一下这里什么都没有。如果你看到你需要我会检查并回复现在你可以不用担心

我已经添加了一个公交车图标，您可以根据需要进行更改。

    @SuppressWarnings({"MissingPermission"})
private void enableLocationComponent(@NonNull Style loadedMapStyle) {
    // Check if permissions are enabled and if not request
    if (PermissionsManager.areLocationPermissionsGranted(mainActivity)) {
        // Activate the MapboxMap LocationComponent to show user location
        // Adding in LocationComponentOptions is also an optional parameter
        locationComponent = mapboxMap.getLocationComponent();
        locationComponent.activateLocationComponent(mainActivity, loadedMapStyle);
        locationComponent.setLocationComponentEnabled(true);

        // Create and customize the LocationComponent's options
        LocationComponentOptions customLocationComponentOptions = LocationComponentOptions.builder(getActivity())
                .foregroundDrawable(R.drawable.bus)
                .build();


        // Get an instance of the component
        locationComponent = mapboxMap.getLocationComponent();

        LocationComponentActivationOptions locationComponentActivationOptions =
                LocationComponentActivationOptions.builder(getActivity(), loadedMapStyle)
                        .locationComponentOptions(customLocationComponentOptions)
                        .build();

        // Activate with options
        locationComponent.activateLocationComponent(locationComponentActivationOptions);

        // Set the component's camera mode
        locationComponent.setCameraMode(CameraMode.TRACKING);

        //  IconFactory iconFactory = IconFactory.getInstance(getActivity());
        //  mapboxMap.addMarker(new MarkerOptions().icon(iconFactory.fromResource(R.drawable.bus)));

    } else {
        permissionsManager = new PermissionsManager(this);
        permissionsManager.requestLocationPermissions(mainActivity);
    }
}
