En esta página, te indicamos cómo controlar el comportamiento de colisión de un marcador.
Cómo configurar el comportamiento de colisión de un marcador
El comportamiento de colisión controla cómo se muestra un marcador si se superpone con otro. El modo en que creas tus marcadores avanzados determina el comportamiento de colisión.
Los marcadores avanzados que se crean con BitmapDescriptorFactory
se conocen como marcadores de mapa de bits. Estos marcadores se establecen en el mapa central.
Todos los demás marcadores avanzados, incluidos aquellos creados con el método AdvancedMarkerOptions.iconView(), se denominan marcadores de vista y se establecen en una capa superior a la del mapa principal.
CollisionBehavior.REQUIRED: (opción predeterminada) Indica que el marcador debe mostrarse siempre, independientemente de las superposiciones.
CollisionBehavior.REQUIRED_AND_HIDES_OPTIONAL: Indica que el marcador debe mostrarse siempre, independientemente de las superposiciones, y que se deben ocultar las etiquetas o los marcadores OPTIONAL_AND_HIDES_LOWER_PRIORITY que se superpongan con este.
CollisionBehavior.OPTIONAL_AND_HIDES_LOWER_PRIORITY: Indica que el marcador solo debe mostrarse si no se superpone con otros.
Si dos marcadores de mapa de bits se superponen entre sí, se mostrará el que tenga el valor de zIndex más alto.
Si tienen el mismo valor de zIndex, se mostrará el que tenga la posición vertical más baja en la pantalla. Si deseas obtener más información sobre zIndex, consulta Marcador z-index.
Si dos marcadores de vista se superponen, se mostrará el que tenga el valor de zIndex más alto. Si tienen el mismo valor de zIndex, el marcador creado más recientemente se superpondrá a los que se hayan creado antes.
Dado que los marcadores de vista se establecen en una capa superior a la de los marcadores de mapa de bits, los marcadores de vista se superponen a los marcadores de mapa de bits. Por lo tanto, te recomendamos que uses marcadores del mismo tipo para tener un mejor control del comportamiento de colisión.
En el siguiente ejemplo, se muestra la configuración del comportamiento de colisión de un marcador:
Kotlin
// Collision behavior can only be changed in the AdvancedMarkerOptions object.
// Changes to collision behavior after a marker has been created are not possible
val collisionBehavior: Int = AdvancedMarkerOptions.CollisionBehavior.REQUIRED_AND_HIDES_OPTIONAL
val advancedMarkerOptions: AdvancedMarkerOptions = AdvancedMarkerOptions()
.position(latLng)
.collisionBehavior(collisionBehavior)
val marker: Marker = map.addMarker(advancedMarkerOptions)
Java
// Collision behavior can only be changed in the AdvancedMarkerOptions object.
// Changes to collision behavior after a marker has been created are not possible
int collisionBehavior = AdvancedMarkerOptions.CollisionBehavior.REQUIRED_AND_HIDES_OPTIONAL;
AdvancedMarkerOptions options =
new AdvancedMarkerOptions()
.position(latLng)
.collisionBehavior(collisionBehavior);
Marker marker = map.addMarker(options);

The way you create an advanced markers\ndetermines how collision behavior works:\n\n- Advanced markers created by using\n [`BitmapDescriptorFactory`](/android/reference/com/google/android/gms/maps/model/BitmapDescriptorFactory)\n are referred to as *bitmap* markers. These markers are drawn by the\n core map.\n\n- All other advanced markers, including those created by\n using the `AdvancedMarkerOptions.iconView()` method, are referred to as\n *view* markers and are drawn on a layer above the core map.\n\n| **Note:** For optimal collision behavior, you should create all advanced markers of the same type. That is, if you are using a view marker for one marker then you should use view markers for all of them.\n\nTo set collision behavior, set\n[`AdvancedMarkerOptions.collisionBehavior`](/android/reference/com/google/android/gms/maps/model/AdvancedMarkerOptions#collisionBehavior(int))\nto one of the following:\n\n- `CollisionBehavior.REQUIRED`: (default) Always display the marker regardless of collision.\n- `CollisionBehavior.REQUIRED_AND_HIDES_OPTIONAL` Always display the marker regardless of collision, and hide any `OPTIONAL_AND_HIDES_LOWER_PRIORITY` markers or labels that would overlap with the marker.\n- `CollisionBehavior.OPTIONAL_AND_HIDES_LOWER_PRIORITY` Display the marker\n only if it does not overlap with other markers.\n\n - If two *bitmap* markers overlap, the one with the higher `zIndex` is\n shown.\n If they have the same `zIndex`, the one with the lower vertical screen\n position is shown. For more information about the `zIndex`, see [Marker\n z-index](/maps/documentation/android-sdk/marker#marker_z-index).\n\n - If two *view* markers overlap, the one with the higher `zIndex` is\n shown. If they have the same `zIndex`, the last created marker\n overlaps any markers created before it.\n\n - Because *view* markers are drawn on a layer above *bitmap* markers,\n *view* markers overlap *bitmap* markers. Therefore, you should try\n to use markers of the same type for better collision control.\n\nThe following example shows setting collision behavior for a marker: \n\n### Kotlin\n\n```kotlin\n// Collision behavior can only be changed in the AdvancedMarkerOptions object.\n// Changes to collision behavior after a marker has been created are not possible\nval collisionBehavior: Int = CollisionBehavior.REQUIRED_AND_HIDES_OPTIONAL\nval advancedMarkerOptions: AdvancedMarkerOptions = AdvancedMarkerOptions()\n .position(LatLng(10.0, 10.0))\n .collisionBehavior(collisionBehavior)\n\nval marker: Marker = map.addMarker(advancedMarkerOptions) ?: error(\"Failed to add marker\")\n\n \n```\n\n### Java\n\n```java\n// Collision behavior can only be changed in the AdvancedMarkerOptions object.\n// Changes to collision behavior after a marker has been created are not possible\nint collisionBehavior = AdvancedMarkerOptions.CollisionBehavior.REQUIRED_AND_HIDES_OPTIONAL;\nAdvancedMarkerOptions options = new AdvancedMarkerOptions()\n .position(new LatLng(10.0, 10.0))\n .collisionBehavior(collisionBehavior);\n\nMarker marker = map.addMarker(options);\n\n \n```\n\n\u003cbr /\u003e"]]
