如何在 mapbox android 中隐藏图层？

Question

   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)
            ));

我需要在我的 statusValue = 0 时隐藏此符号，并在 statusValue = 1 时再次出现。请帮忙

将可见性 属性 更改为 NONE/VISIBLE:

public void updateLayer(final int statusValue) {
    mapboxMap.getStyle(new Style.OnStyleLoaded() {
        @Override
        public void onStyleLoaded(@NonNull Style style) {
            Layer layer = style.getLayer("sanciangkoFlood1-layer-id");
            if (layer != null) {
                layer.setProperties(PropertyFactory.visibility(
                        statusValue == 0 ? Property.NONE : Property.VISIBLE
                ));
            }
        }
    });
}
