Este documento mostra como personalizar os marcadores de veículo e local no mapa
usado no app de rastreamento de envios baseado na Web para consumidores.
Com o SDK do consumidor JavaScript, é possível personalizar a aparência de dois
tipos de marcadores adicionados ao mapa:
Isso pode ser feito de duas maneiras:
- Mais simples: especifique um objeto
MarkerOptions
para aplicar a todos os marcadores do mesmo tipo. O SDK do consumidor aplica o estilo em duas situações: antes de adicionar os marcadores ao mapa e quando os dados usados para os marcadores mudam.
- Mais avançado: especifique uma função de personalização. As funções de personalização
permitem estilizar os marcadores com base em dados, além de adicionar
interatividade a eles, como o processamento de cliques. Especificamente, o SDK do
consumidor transmite dados para a função de personalização sobre o tipo de objeto que o
marcador representa: veículo ou destino. Isso permite que o estilo do marcador
mude com base no estado atual do elemento de marcador. Por
exemplo, o número de paradas planejadas restantes até o destino. Você
pode até mesmo fazer junções com dados de fontes fora do Fleet Engine e estilizar o
marcador com base nessas informações.
Exemplo simples: use MarkerOptions
O exemplo a seguir mostra como configurar o estilo de um marcador de veículo com um objeto MarkerOptions
. Este exemplo define a opacidade do marcador como 50%.
JavaScript
deliveryVehicleMarkerCustomization = {
opacity: 0.5
};
TypeScript
deliveryVehicleMarkerCustomization = {
opacity: 0.5
};
Exemplo avançado: usar uma função de personalização
O exemplo a seguir mostra como configurar o estilo de um marcador de veículo para
mostrar a contagem restante de paradas antes de chegar à parada da
tarefa programada.
JavaScript
deliveryVehicleMarkerCustomization =
(params) => {
var stopsLeft = params.taskTrackingInfo.remainingStopCount;
params.marker.setLabel(`${stopsLeft}`);
};
TypeScript
deliveryVehicleMarkerCustomization =
(params: ShipmentMarkerCustomizationFunctionParams) => {
const stopsLeft = params.taskTrackingInfo.remainingStopCount;
params.marker.setLabel(`${stopsLeft}`);
};
Adicionar o processamento de cliques aos marcadores
É possível adicionar o processamento de cliques a qualquer marcador, como no exemplo a seguir
para um marcador de veículo.
JavaScript
deliveryVehicleMarkerCustomization =
(params) => {
if (params.isNew) {
params.marker.addListener('click', () => {
// Perform desired action.
});
}
};
TypeScript
deliveryVehicleMarkerCustomization =
(params: ShipmentMarkerCustomizationFunctionParams) => {
if (params.isNew) {
params.marker.addListener('click', () => {
// Perform desired action.
});
}
};
Mostrar mais informações sobre marcadores
Você pode usar um InfoWindow
para mostrar mais informações sobre um veículo ou marcador de local. O exemplo a seguir cria um
InfoWindow
e o anexa a um marcador de veículo:
JavaScript
// 1. Create an info window.
const infoWindow = new google.maps.InfoWindow(
{disableAutoPan: true});
locationProvider.addListener('update', e => {
const stopsCount =
e.taskTrackingInfo.remainingStopCount;
infoWindow.setContent(
`Your vehicle is ${stopsCount} stops away.`);
// 2. Attach the info window to a vehicle marker.
// This property can return multiple markers.
const marker = mapView.vehicleMarkers[0];
infoWindow.open(mapView.map, marker);
});
// 3. Close the info window.
infoWindow.close();
TypeScript
// 1. Create an info window.
const infoWindow = new google.maps.InfoWindow(
{disableAutoPan: true});
locationProvider.addListener('update', (e: google.maps.journeySharing.FleetEngineShipmentLocationProviderUpdateEvent) => {
const stopsCount =
e.taskTrackingInfo.remainingStopCount;
infoWindow.setContent(
`Your vehicle is ${stopsCount} stops away.`);
// 2. Attach the info window to a vehicle marker.
// This property can return multiple markers.
const marker = mapView.vehicleMarkers[0];
infoWindow.open(mapView.map, marker);
});
// 3. Close the info window.
infoWindow.close();

The Consumer SDK then applies the styling in two situations: before adding the markers to the map, and when the data used for the markers have changed.\n- **More advanced**: Specify a customization function. Customization functions allow for styling of the markers based on data, as well as adding interactivity to markers, such as click handling. Specifically, the Consumer SDK passes data to the customization function about the type of object the marker represents: vehicle or destination. This then allows marker styling to change based on the current state of the marker element itself; for example, the number of planned stops remaining until the destination. You can even join against data from sources outside Fleet Engine and style the marker based on that information.\n\nSimple example: use `MarkerOptions`\n\nThe following example shows how to configure a vehicle marker's styling with a\n`MarkerOptions` object. This example sets the marker opacity to 50%.\n\n\u003cbr /\u003e\n\nJavaScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization = {\n opacity: 0.5\n };\n\n\u003cbr /\u003e\n\nTypeScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization = {\n opacity: 0.5\n };\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nAdvanced example: use a customization function\n\nThe following example shows how to configure a vehicle marker's styling to\ndisplay the remaining stop count for the vehicle before reaching the stop for\nthe scheduled task.\n\n\u003cbr /\u003e\n\nJavaScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params) =\u003e {\n var stopsLeft = params.taskTrackingInfo.remainingStopCount;\n params.marker.setLabel(`${stopsLeft}`);\n };\n\n\u003cbr /\u003e\n\nTypeScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params: ShipmentMarkerCustomizationFunctionParams) =\u003e {\n const stopsLeft = params.taskTrackingInfo.remainingStopCount;\n params.marker.setLabel(`${stopsLeft}`);\n };\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nAdd click handling to markers\n\nYou can add click handling to any marker, such as in the following example\nfor a vehicle marker.\n\n\u003cbr /\u003e\n\nJavaScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params) =\u003e {\n if (params.isNew) {\n params.marker.addListener('click', () =\u003e {\n // Perform desired action.\n });\n }\n };\n\n\u003cbr /\u003e\n\nTypeScript\n\n\u003cbr /\u003e\n\n deliveryVehicleMarkerCustomization =\n (params: ShipmentMarkerCustomizationFunctionParams) =\u003e {\n if (params.isNew) {\n params.marker.addListener('click', () =\u003e {\n // Perform desired action.\n });\n }\n };\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nDisplay additional information for markers\n\nYou can use an [`InfoWindow`](/maps/documentation/javascript/infowindows) to display additional information about a\nvehicle or location marker.
