Is there a way to adjust the font color of a markerclusterer marker? Below is my current code for customizing the marker's style:
mcOptions = {styles: [{
height: 27,
url: "image.png",
width: 35
}],
maxZoom: 8
}
var markerCluster = new MarkerClusterer(map, markers, mcOptions);
Check out this interactive JSFIDDLE showcasing how to modify the font properties of the clustermarker with the following code:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>MarkerClusterer v3 Simple Example</title>
<style >
body {
margin: 0;
padding: 10px 20px 20px;
font-family: Arial;
font-size: 16px;
}
#map-container {
padding: 6px;
border-width: 1px;
border-style: solid;
border-color: #ccc #ccc #999 #ccc;

box-shadow: rgba(64, 64, 64, 0.1) 0 2px 5px;
width: 600px;
}
#map {

}

For more options and customizations, visit the API reference link.
For more information on the Marker Clusterer feature, you can refer to the Documentation specifically under the ClusterIconStyle class.
Within the ClusterIconStyle class, there is an option called textColor that allows you to customize the color of the label text displayed on the cluster icon.
To simplify the process, you can choose to pass only one element in the styles option. Here's an example:
var options = {
maxZoom: 15,
styles:[{
url: 'https://googlemaps.github.io/js-marker-clusterer/images/m1.png',
width: 53,
height: 53,
textColor: '#fff',
}]
};
var mc = new MarkerClusterer(map, markers, options);
However, using just one element means you will have the same image for all cluster sizes (1-10-100). It might be more effective to pass 5 elements, one for each cluster size, but this can lead to a lot of code (especially when dealing with multiple clusterers on the map).
For a more efficient approach, you can try the following:
var mc = new MarkerClusterer(map, [], {
imagePath: 'https://googlemaps.github.io/js-marker-clusterer/images/m',
maxZoom: 15
});
mc.setStyles(mc.getStyles().map(function (style) {
style.textColor = '#fff';
return style;
}));
mc.addMarkers(markers)
public Bitmap customizeIcon(String text, int newColor) {
setupIconViews();
if (mTextView != null) {
mTextView.setText(text);
mTextView.setTextColor(newColor);
}
return makeCustomizedIcon();
}
Customizing the Google Map cluster icon involves changing the text color displayed on the blue background. To do this, modify the customizeIcon method in the IconGenerator.java file.
