[See the demo app](#demo-app)\n\nIntroduction\n------------\n\n\nIn previous tutorials, you've learned how to add features from\n[KML](/maps/documentation/android-sdk/utility/kml) and\n[GeoJSON](/maps/documentation/android-sdk/utility/geojson) to your map, as well as\n[clusters](/maps/documentation/android-sdk/utility/marker-clustering) of markers.\nBut what if you want to add several of these layers on the same map and get independent click\nevents for each?\n\nAdding multiple cluster, KML, and GeoJSON layers\n------------------------------------------------\n\n\nThe library includes `Manager`objects to help manage click events for multiple types\nof layers. So, before you set up your layers you'll first need to instantiate these and pass in\nyour `GoogleMap`: \n\n### Kotlin\n\n```kotlin\nval markerManager = MarkerManager(map)\nval groundOverlayManager = GroundOverlayManager(map!!)\nval polygonManager = PolygonManager(map)\nval polylineManager = PolylineManager(map)\n\n \n```\n\n### Java\n\n```java\nMarkerManager markerManager = new MarkerManager(map);\nGroundOverlayManager groundOverlayManager = new GroundOverlayManager(map);\nPolygonManager polygonManager = new PolygonManager(map);\nPolylineManager polylineManager = new PolylineManager(map);\n\n \n```\n\n\nNext, you can pass these manager classes into the constructors of the other layers when you\nset them up: \n\n### Kotlin\n\n```kotlin\nval clusterManager =\n ClusterManager\u003cMyItem\u003e(context, map, markerManager)\nval geoJsonLineLayer = GeoJsonLayer(\n map,\n R.raw.geojson_file,\n context,\n markerManager,\n polygonManager,\n polylineManager,\n groundOverlayManager\n)\nval kmlPolylineLayer = KmlLayer(\n map,\n R.raw.kml_file,\n context,\n markerManager,\n polygonManager,\n polylineManager,\n groundOverlayManager,\n null\n)\n\n \n```\n\n### Java\n\n```java\nClusterManager\u003cMyItem\u003e clusterManager = new ClusterManager\u003c\u003e(context, map, markerManager);\nGeoJsonLayer geoJsonLineLayer = new GeoJsonLayer(map, R.raw.geojson_file, context, markerManager, polygonManager, polylineManager, groundOverlayManager);\nKmlLayer kmlPolylineLayer = new KmlLayer(map, R.raw.kml_file, context, markerManager, polygonManager, polylineManager, groundOverlayManager, null);\n\n \n```\n\nAdding your own features\n------------------------\n\n\nIf you want to add your own markers, ground overlays, polylines, or polygons alongside these\nlayers, create your own `Collection` and then use the `Managers`\nto add the feature instead of directly adding them to the `GoogleMap` object.\n\nFor example, if you want to add a new marker: \n\n### Kotlin\n\n```kotlin\nval markerCollection =\n markerManager.newCollection()\nmarkerCollection.addMarker(\n MarkerOptions()\n .position(LatLng(51.150000, -0.150032))\n .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))\n .title(\"Unclustered marker\")\n)\n\n \n```\n\n### Java\n\n```java\nMarkerManager.Collection markerCollection = markerManager.newCollection();\nmarkerCollection.addMarker(new MarkerOptions()\n .position(new LatLng(51.150000, -0.150032))\n .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))\n .title(\"Unclustered marker\"));\n\n \n```\n\nHandling click events\n---------------------\n\n\nFor clusters, KML, and GeoJSON, click listeners work like normal - as long as you pass in the\n`Manager` classes in the constructor of the layer you're setting.\n\nFor example, here's how to set up a click listener for the KML layer: \n\n### Kotlin\n\n```kotlin\nkmlPolylineLayer.addLayerToMap()\nkmlPolylineLayer.setOnFeatureClickListener { feature: Feature -\u003e\n Toast.makeText(context,\n \"KML polyline clicked: ${feature.getProperty(\"name\")}\",\n Toast.LENGTH_SHORT\n ).show()\n}\n\n \n```\n\n### Java\n\n```java\nkmlPolylineLayer.addLayerToMap();\nkmlPolylineLayer.setOnFeatureClickListener(feature -\u003e Toast.makeText(context,\n \"KML polyline clicked: \" + feature.getProperty(\"name\"),\n Toast.LENGTH_SHORT).show());\n\n \n```\n\n\nWhen you add your own markers, ground overlays, polylines, or polygons, just be sure to add click\nlisteners to those `Collection` objects. For example, here's how to set up the marker\nclick listener on the `markerCollection`: \n\n### Kotlin\n\n```kotlin\nmarkerCollection.setOnMarkerClickListener { marker: Marker -\u003e\n Toast.makeText(\n context,\n \"Marker clicked: ${marker.title}\",\n Toast.LENGTH_SHORT\n ).show()\n false\n}\n\n \n```\n\n### Java\n\n```java\nmarkerCollection.setOnMarkerClickListener(marker -\u003e { Toast.makeText(context,\n \"Marker clicked: \" + marker.getTitle(),\n Toast.LENGTH_SHORT).show();\n return false;\n});\n\n \n```\n\nSee the demo app\n----------------\n\nFor an example of adding multiple layers, take a look at the `MultiLayerDemoActivity`\nin the demo app that ships with the utility library. The [setup guide](/maps/documentation/android-sdk/utility/setup) shows you how to run\nthe demo app."]]
