android - How to remove marker from google map v2?

Question

I have an alerdialog that pops up when tapping on the marker with two options, on of the options are to remove the marker. Now this works perfectly, except the user taps on the remove marker option and then the alert dialog dissapears but the marker is still there. When i tap the marker again and select remove, then it removes from the map. Really weird and i don't know why it is doing that.

Here is my code:

 @Override
        public boolean onMarkerClick(final Marker marker) {
            AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                    context)
  .......

.setNegativeButton("Delete Marker",new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,int id) {
                            marker.remove();
                            dialog.cancel();

Any ideas why this is happening?

Answer 1

Your marker.remove() code does not work?

Or say what is your actual problem?

set All markder within a variable like

HashMap<Integer, Marker> myMarkersHash = new HashMap<Integer, Marker>();

and put marker value

myMarkersHash.put(IndexValue, marker);

and to show/Hide marker use this code

    myMarkersHash.get(IndexValue).setVisible(false);
// or
   myMarkersHash.get(IndexValue).setVisible(true);
