I am developing an application in android studio. I have a map with several markers that I generate as shown in the image, when I click on the inforwindows I get a contextual menu with several options what I need is to choose an option the markador where I am pocicionado change of bone icon if I choose delivered I want the markador to change to green and so it depends on the option I choose to change color.

This is the code I'm using

    public boolean onContextItemSelected(MenuItem item) {
    String id = "";
    id = TituloGlobal.substring(0, TituloGlobal.indexOf(" -"));
    switch (item.getItemId()){
        case R.id.meEntregado:
            guardarDatosCliente(id, "0", "3");


            break;
        case R.id.meParcial:
            guardarDatosCliente(id, "2", "4");
            mMap.

            break;
        case R.id.meCTotal:
            guardarDatosCliente(id, "1", "4");
            break;
        case R.id.meNPlata:
            guardarDatosCliente(id, "1", "5");
            break;
        case R.id.meRParcial:
            guardarDatosCliente(id, "2", "5");
            break;
        case R.id.meNSalio:
            guardarDatosCliente(id, "3", "5");
            break;
        case R.id.meNalcanzar:
            guardarDatosCliente(id, "4", "5");
            break;
    }


    return super.onContextItemSelected(item);
}

I am new in this programming language, I hope you can help me and thanks in advance.

What you need to change the color marker is the following line

marker.setIcon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));

where HUE_BLUE is one of the colors you can use. You can see the list here and market is the instance on marker that you used for that specific marker.

To save the marker reference, you can create an array with all the markers once you add them to the map, something like this:

private ArrayList<Marker> mMarcadores;

mMarcadores.add(mGoogleMap.addMarker(new MarkerOptions()....);

You can use the setOnMarkerClickListener , and that's where you can receive the marker you're using. For what you put in the comments, you are using the setOnInfoWindowClickListener that is different.

Then to your openContextMenu function, I do not know how it is implemented, so I can not help much but you can receive the bookmark, choose the option and then change the color

mGoogleMap.setOnMarkerClickListener(marker -> {
    openContextMenu(findViewById(R.id.map), marker);
    return false;
});

openContextMenu(MapView mapa,Marker marker){
    //etc lanzar dialogo
    //cachar opcion del dialogo
    marker.setIcon(BitmapDescriptorFactory
        .defaultMarker(BitmapDescriptorFactory.HUE_BLUE));
                    return false;
}
