Android OverlayItem.setMarker(): Change the marker for one item

Question

Trying to change the marker from an overlay item I noticed the setMarker() makes the item not visible. Here's the code sample.

//Create new marker
Drawable icon = this.getResources().getDrawable(R.drawable.marker);

//Set the new marker to the overlay
overlayItem.setMarker(icon);

have you found a solution for this? I'm facing the same issue. calling setMarker() with a specific drawable makes the icon invisible... – Lobel

You have to specify the bounding rectangle using setBounds() – Grishilda

that indeed works, you should answer the question ;) – Lobel

Answer 1

A bounding rectangle needs to be specified for the Drawable:

//Create new marker
Drawable icon = this.getResources().getDrawable(R.drawable.marker);

//Set the bounding for the drawable
icon.setBounds(
    0 - icon.getIntrinsicWidth() / 2, 0 - icon.getIntrinsicHeight(), 
    icon.getIntrinsicWidth() / 2, 0);

//Set the new marker to the overlay
overlayItem.setMarker(icon);

Answer 2

I believe this would work:

public void addOverlay(final OverlayItem overlay)
    {
        creditOverlay.add(overlay);
        populate();
        boundCenter(customMarker);
    }

You will have to call boundCenter or boundCenterBottom while adding overlay in map overlay list. In SetMarker() just set the custom maker.

This will cause all the items to use the same marker, unless the method is changed to: `addOverlay(OverlayItem, Drawable) – Grishilda
