clusterMarker | Baidu map aggregation

I'm implementing github.com/jawj/OverlappingMarkerSpiderfier to make clusters of Pin's on my google map.

What I want to do is to have a i cluster icon with a number in it that tells the user how many pin's there are - Just like google default cluster view. Se screendump. If it's not possible to have a number, that is okay as long as i can set a cluster icon of my choice. Screen shows how clusters looks on google https://developers.google.com/maps/documentation/javascript/marker-clustering

When i click the cluster it opens up and show the pin's. In my case each pin is a small thumbnail. Se screendump Screen shows how it looks after i click the cluster

My problem is that i dont know how to make something like the google cluster solution. My code show a thumbnail as the cluster icon (see screendumb) and i want the 'google solution'. Screen shows how it looks before i click the cluster

-- My script so far --

I hope you can help me.

I am creating a map using mapbox-gl and I am rendering some coordinates [lon, lat].

Some values are null though, so I am trying to filter them out using a reducer, but for those empty values I am only creating an empty object I can't delete and getting an error (filteredPositions.lon -> error: Property 'lon' does not exist on type '{}')

How can I only render those clusters with not null values? Here is my code:

I created MY clustering showing my custom Icons, but how can I show the numbers on my custom clustering?

I want to show my custom marker cluster with the number inside. Does anyone have any idea?

I've created a map with multi markers from a JSON file. I'm trying to add a marker cluster, but I'm ending up with the cluster and markers showing at the same time. This is what I see at the moment:

I've added the script below to my index.html page:

I had an issue with my custom markers, I want to make it such as a cluster markers (group of makers), but it doesn't work, I found all the markers in the Google Maps, so even I use a clusterManager to handle this situation I can't get the wanted result:

I use the code from github(It's not my code) as an example https://github.com/mitchtabian/Google-Maps-2018/tree/displaying-trip-duration-of-polylines-end

This is my issue:

• Let's assume that there are some users (markers).
• I want to change the icon of marker to another picture from the internet, but it doesn't work.

I have two problems:

1. The onBeforeClusterItemRendered() method doesn't show the image. If I use the image from the resource as in the original example then it works.

2. The setUpdateMarker() method changes two images only on one marker instead of showing the image on each marker.

   ...

Excuse my ignorance but I am very new to Android Studio and Java. I have adapted a lot the following code from another course to my needs, but it is not working.

I am trying to add custom markers to my Google maps Android app. Lhe locations of the markers are stored as geopoints on firebase. I have attempted to do so using cluster marker. The app crashes immediately when I attempt to run it with the following shortened error.

java.lang.NullPointerException: Attempt to invoke virtual method 'com.google.firebase.firestore.CollectionReference com.google.firebase.firestore.FirebaseFirestore.collection(java.lang.String)' on a null object reference at com.codingwithmitch.googlemaps2018.ui.MapsActivity.addMapMarkers(MapsActivity.java:400) at com.codingwithmitch.googlemaps2018.ui.MapsActivity.onMapReady(MapsActivity.java:486)

I am attempting to display every geopoint in the Stop Locations Collection

I cannot screen shot my firebase but it looks as follows:

Collection "Stop Locations">>>>>Documents "KzDQ2sITZ3O8GEoZgp0I",...etc >>>>>Fields Geo:"" Name:"" avatar:"" loc_id""

If I were to guess I would say the mLocationInformations is empty, probably originating from here >> mLocationInformations.add(document.toObject(LocationInformation.class))

code from MapsActivity:

A would like to visualize MapQuickItem depend on if condition.

I have two custom objects ClusterMarker which is a Rectangle and PromotionMarker which is an Image object. I would like to assign them to MapQuickItem (which is delegate for MapItemView) using sourceItem property.

Here is how I'm doing it:

I have a multidimensional array and want to sort it by distance:
