在MapBox上添加标记的最佳方法是什么? [英] What is the best way to add markers on MapBox?
本文介绍了在MapBox上添加标记的最佳方法是什么?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
众所周知, mapbox.addMarker()
已弃用!我试图找出使用符号层
As most of you know, mapbox.addMarker()
is deprecated!
I tried to figure the new way to add markers which are using Symbol Layer
我正在使用此代码,它正在为我工作!但是每次我要添加标记时,它都会重新定义地图的样式
I'm using this code, it is working for me! but it re-define the Style of the map every time I want to add a marker
下面是代码:
//Add Marker to the Map
public void addMarker(@NonNull LatLng point) {
Feature feature = Feature.fromGeometry(Point.fromLngLat(point.getLongitude(), point.getLatitude()));
mapboxMap
.setStyle(new Style.Builder()
.fromUri("mapbox://styles/mapbox/cjf4m44iw0uza2spb3q0a7s41")
.withImage(ICON_ID, marker)
.withSource(new GeoJsonSource(SOURCE_ID, feature))
.withLayer(new SymbolLayer(LAYER_ID, SOURCE_ID)
.withProperties(PropertyFactory.iconImage(ICON_ID),
iconAllowOverlap(true),
iconIgnorePlacement(true),
iconOffset(new Float[]{0f, -9f}))));
}
因此,我想知道在最新的MapBox SDK 8.5.0
谢谢!
推荐答案
mapboxMap.setStyle(Style.MAPBOX_STREETS, new Style.OnStyleLoaded() {
@Override
public void onStyleLoaded(@NonNull final Style style) {
AddSanciangkoStreet(style);
SanciangkoStreetMarker();
}
}
private void AddSanciangkoStreet(@NonNull Style style) {
style.addImage("sanciangko-street",
BitmapUtils.getBitmapFromDrawable(getResources().getDrawable(R.drawable.floodicon)));
style.addSource(new GeoJsonSource("sanciangkoFlood1-source-id"));
style.addLayer(new SymbolLayer("sanciangkoFlood1-layer-id", "sanciangkoFlood1-source-id").withProperties(
iconImage("sanciangko-street"),
iconIgnorePlacement(true),
iconAllowOverlap(true),
iconSize(1f)
));
}
private void SanciangkoStreetMarker() {
if (map.getStyle() != null) {
GeoJsonSource sanciangkoFlood1 = map.getStyle().getSourceAs("sanciangkoFlood1-source-id");
if (sanciangkoFlood1 != null) {
sanciangkoFlood1.setGeoJson(FeatureCollection.fromFeature(
Feature.fromGeometry(Point.fromLngLat(123.895801, 10.297237))
));
}
}
}
