지형지물 레이어가 사용자 click
이벤트에 응답하여 클릭된 경계의 장소 ID와 지형지물 유형을 가져오도록 할 수 있습니다. 다음 예시 지도에는 국가 레이어의 경계, 선택한 국가와 연결된 클릭된 다각형의 스타일을 지정하는 이벤트 핸들러가 표시됩니다.
클릭 이벤트 핸들러 작성
지형지물 레이어에서 클릭 이벤트가 발생하면 Android용 Maps SDK는 FeatureClickEvent
객체를 이벤트 핸들러에 전달합니다. FeatureClickEvent
를 사용하여 클릭의 위도 및 경도 좌표와 클릭의 영향을 받는 기능 목록을 가져옵니다.
지형지물 레이어 이벤트 처리
다음 단계에 따라 지형지물 레이어에서 이벤트를 처리합니다. 이 예에서는 선택한 국가를 나타내는 다각형에 빨간색 채우기를 적용하기 위해 국가 피처 레이어의 클릭 이벤트 핸들러를 정의합니다.
FeatureLayer.setFeatureStyle()
를 호출하면 스타일 팩토리 함수가 지형지물 레이어의 모든 지형지물에 스타일을 설정합니다. 이벤트 핸들러에서 지형지물의 스타일을 업데이트하려면 FeatureLayer.setFeatureStyle()
를 호출하여 모든 지형지물에 업데이트된 스타일을 설정해야 합니다.
새 지도 ID와 지도 스타일을 아직 만들지 않았다면 시작하기의 단계에 따라 만드세요. 국가 지형지물 레이어를 사용 설정해야 합니다.
클래스가 FeatureLayer.OnFeatureClickListener
을 구현하는지 확인합니다.
FeatureLayer.addOnFeatureClickListener()
를 호출하여 지형지물 클릭 이벤트의 이벤트 핸들러를 등록합니다.

The\nfollowing example map shows the boundaries for the Country layer, and\nshows an event handler that styles the clicked polygon associated with the\nselected country.\n\nWrite a click event handler\n---------------------------\n\nWhen a click event occurs on a feature layer, the Maps SDK for Android passes a\n[`FeatureClickEvent`](/android/reference/com/google/android/gms/maps/model/FeatureClickEvent)\nobject to the event handler. Use the `FeatureClickEvent` to get the latitude\nand longitude coordinates of the click and a list of features affected by the\nclick.\n\nHandle feature layer events\n---------------------------\n\nTake the following steps to handle events on a feature layer. In this example,\nyou define a click event handler for the Country feature layer to apply a red\nfill to the polygon representing the selected country.\n\nWhen you call\n[`FeatureLayer.setFeatureStyle()`](/android/reference/com/google/android/gms/maps/model/FeatureLayer#setFeatureStyle(com.google.android.gms.maps.model.FeatureLayer.StyleFactory)),\nthe style factory function sets the style on all features in the\nfeature layer. To update the style of a feature in the event handler, you must\ncall `FeatureLayer.setFeatureStyle()` to set the updated style on all\nfeatures.\n\n1. If you haven't already done so, follow the steps in\n [Get Started](/maps/documentation/android/dds-boundaries/start)\n to create a new map ID and map style. Be sure to enable the **Country**\n feature layer.\n\n2. Make sure your class implements\n [`FeatureLayer.OnFeatureClickListener`](/android/reference/com/google/android/gms/maps/model/FeatureLayer.OnFeatureClickListener).\n\n3. Register an event handler for feature click events by calling\n [`FeatureLayer.addOnFeatureClickListener()`](/android/reference/com/google/android/gms/maps/model/FeatureLayer#addOnFeatureClickListener(com.google.android.gms.maps.model.FeatureLayer.OnFeatureClickListener)).\n\n ### Java\n\n\n ```java\n private FeatureLayer countryLayer;\n\n @Override\n public void onMapReady(GoogleMap map) {\n\n // Get the COUNTRY feature layer.\n countryLayer = map.getFeatureLayer(new FeatureLayerOptions.Builder()\n .featureType(FeatureType.COUNTRY)\n .build());\n\n // Register the click event handler for the Country layer.\n countryLayer.addOnFeatureClickListener(this);\n\n // Apply default style to all countries on load to enable clicking.\n styleCountryLayer();\n }\n\n // Set default fill and border for all countries to ensure that they respond\n // to click events.\n private void styleCountryLayer() {\n FeatureLayer.StyleFactory styleFactory = (Feature feature) -\u003e {\n return new FeatureStyle.Builder()\n // Set the fill color for the country as white with a 10% opacity.\n .fillColor(Color.argb(0.1, 0, 0, 0))\n // Set border color to solid black.\n .strokeColor(Color.BLACK)\n .build();\n };\n\n // Apply the style factory function to the country feature layer.\n countryLayer.setFeatureStyle(styleFactory);\n }\n ```\n\n \u003cbr /\u003e\n\n ### Kotlin\n\n\n ```java\n private var countryLayer: FeatureLayer? = null\n\n override fun onMapReady(googleMap: GoogleMap) {\n // Get the COUNTRY feature layer.\n countryLayer = googleMap.getFeatureLayer(FeatureLayerOptions.Builder()\n .featureType(FeatureType.COUNTRY)\n .build())\n\n // Register the click event handler for the Country layer.\n countryLayer?.addOnFeatureClickListener(this)\n\n // Apply default style to all countries on load to enable clicking.\n styleCountryLayer()\n }\n\n // Set default fill and border for all countries to ensure that they respond\n // to click events.\n private fun styleCountryLayer() {\n val styleFactory = FeatureLayer.StyleFactory { feature: Feature -\u003e\n return@StyleFactory FeatureStyle.Builder()\n // Set the fill color for the country as white with a 10% opacity.\n .fillColor(Color.argb(0.1f, 0f, 0f, 0f))\n // Set border color to solid black.\n .strokeColor(Color.BLACK)\n .build()\n }\n\n // Apply the style factory function to the country feature layer.\n countryLayer?.setFeatureStyle(styleFactory)\n }\n ```\n\n \u003cbr /\u003e\n\n4. Apply a fill color of red to the selected country. Only visible features are\n clickable.\n\n ### Java\n\n\n ```java\n @Override\n // Define the click event handler.\n public void onFeatureClick(FeatureClickEvent event) {\n\n // Get the list of features affected by the click using\n // getPlaceIds() defined below.\n List\u003cString\u003e selectedPlaceIds = getPlaceIds(event.getFeatures());\n\n if (!selectedPlaceIds.isEmpty()) {\n FeatureLayer.StyleFactory styleFactory = (Feature feature) -\u003e {\n // Use PlaceFeature to get the placeID of the country.\n if (feature instanceof PlaceFeature) {\n if (selectedPlaceIds.contains(((PlaceFeature) feature).getPlaceId())) {\n return new FeatureStyle.Builder()\n // Set the fill color to red.\n .fillColor(Color.RED)\n .build();\n }\n }\n return null;\n };\n\n // Apply the style factory function to the feature layer.\n countryLayer.setFeatureStyle(styleFactory);\n }\n }\n\n // Get a List of place IDs from the FeatureClickEvent object.\n private List\u003cString\u003e getPlaceIds(List\u003cFeature\u003e features) {\n List\u003cString\u003e placeIds = new ArrayList\u003c\u003e();\n for (Feature feature : features) {\n if (feature instanceof PlaceFeature) {\n placeIds.add(((PlaceFeature) feature).getPlaceId());\n }\n }\n return placeIds;\n }\n ```\n\n \u003cbr /\u003e\n\n ### Kotlin\n\n\n ```java\n // Define the click event handler.\n override fun onFeatureClick(event: FeatureClickEvent) {\n\n // Get the list of features affected by the click using\n // getPlaceIds() defined below.\n val selectedPlaceIds = getPlaceIds(event.getFeatures())\n if (!selectedPlaceIds.isEmpty()) {\n val styleFactory = FeatureLayer.StyleFactory { feature: Feature -\u003e\n // Use PlaceFeature to get the placeID of the country.\n if (feature is PlaceFeature) {\n if (selectedPlaceIds.contains((feature as PlaceFeature).getPlaceId())) {\n return@StyleFactory FeatureStyle.Builder()\n // Set the fill color to red.\n .fillColor(Color.RED)\n .build()\n }\n }\n return@StyleFactory null\n }\n\n // Apply the style factory function to the feature layer.\n countryLayer?.setFeatureStyle(styleFactory)\n }\n }\n\n // Get a List of place IDs from the FeatureClickEvent object.\n private fun getPlaceIds(features: List\u003cFeature\u003e): List\u003cString\u003e {\n val placeIds: MutableList\u003cString\u003e = ArrayList()\n for (feature in features) {\n if (feature is PlaceFeature) {\n placeIds.add((feature as PlaceFeature).getPlaceId())\n }\n }\n return placeIds\n }\n ```\n\n \u003cbr /\u003e"]]
