在Android上的Google地图中更改标记

Question

I'am developing an application that add markers to a map. But use the default marker is some heavy and show unclear information. I'd like to add just small points with a number. How can I do this? O found some tutorials to add image in the placer of the default icon of the marker, but I don't thinks that is the case here.

This is the code i'm using now.

                    Marker marked = mMap.addMarker(new MarkerOptions()
                                    .position(ltlt)
                                    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))
                                    .title("Numero:" + i)
                                    .snippet("Snippet")
                    );

This work to me:

Configure the iconGenerator

    IconGenerator iconFactory = new IconGenerator(this);
    iconFactory.setContentPadding(0, 0, 0, 0);
    iconFactory.setBackground(Drawable.createFromPath("R.drawable.nada.jpg"));  // transparent image 10px x 10px
    iconFactory.setTextAppearance(R.style.iconGenText);

Style used:

<style name="iconGenText">
    <item name="android:textSize">12sp</item>
    <item name="android:textColor">#000000</item>
</style>

and my markeradd:

                    Marker marked = mMap.addMarker(new MarkerOptions()
                            .position(ltlt)
                            .icon(BitmapDescriptorFactory.fromBitmap(iconFactory.makeIcon("" + i)))
                            .title("Numero:" + i)
                            .snippet("Snippet")
                    );
