Overlapping markers - on marker click - marker in the back is getting selected instead of the frontmost.

[epiphany27]

I have several markers close to each other on map, so much so that they sort of partially/fully overlap each other. I haven't specified any z-Index explicitly while adding the markers on the map, hence z-Index for all markers is 0.0 by default.

The problem is that when I tap on one of the overlapping markers which is at the frontmost position, the marker at the backmost is getting selected. So if there are 3 overlapping markers (say marker-1, marker-2, marker-3) one behind the other, marker-1 being at the front, marker-3 at the back and marker-2 is the middle of marker-1 & 2, when I click on marker-1, marker-3 gets selected instead. When I click again (on the same click point), marker-2 gets selected next, click again the third time, marker-1 gets selected finally.

At first, I thought there is probably a bug on my end or in the Google Maps library itself. After enough research online, I finally landed on google maps docs which doesn't quite answer my question.
From google-map API docs:- https://developers.google.com/maps/documentation/android-api/marker#marker_click_events

Clicking on a cluster of markers causes subsequent clicks to cycle through the cluster, selecting each in turn. The order of the cycle first prioritises z-index, then proximity to the click point.

(All marker's z-Indices are the same (0.0) in my case.)

On the other hand, when I checked on iOS (using iOS google maps library), I found the marker selection sequence to be correct (Marker-1 -> Marker-2 -> Marker-3) unlike Android which was the exact opposite.

Is this intended to be this way on Android? Or is it a Google Map library bug. Is there a way I could reverse the marker click sequence on Android like the way it's on iOS.

I know, one workaround could be to use marker clustering (ClusterManager etc) in such cases of overlapping markers, but I don't want to go that route for now.

Any comment will be highly appreciated.
Thanks.

same issue.Background marker get the click event not front one.

I had the same issue, any solution??????????????

Someone please 🚨

I don't know if it's the best solution, but, my workaround is to set a high value in a variable as maxZIndex (the number of markers + 1 is fine), and then when I click on the marker:
previousMarker.zIndex = previousMarker.zIndex - 1
currentMarker.zIndex = maxZIndex + 1f
The current marker is then assigned to the previous to move it backward on the next click
