Answer 1

I don't know if there is an easier way than what I used that was a year a go this method takes a lot of time if the data set is big so use it on small data set or talk to the designer for other options.

you can create a layout with what you want the get the bitmap of this layout this add the bitmap as a marker to the map since add marker only takes images. *you need to set the data before creating the bitmap

first step inflate and set data to your layout

View marker = ((LayoutInflater) getActivity()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE))
                .inflate(R.layout.marker_layout, null);

second get the bitmap from this view

Bitmap bitmap = createDrawableFromView(
                                getActivity(), marker);

third add the bitmap as a marker

   MarkerOptions mo = new MarkerOptions().position(
                                    new LatLng(lat, lng))
                                    // .title(address)
                                    .snippet(i + "")
                                    .icon(BitmapDescriptorFactory
                                            .fromBitmap(bitmap));
                            Marker customMarker = googleMap.addMarker(mo);

this is how to get the bitmap

public static Bitmap createDrawableFromView(Context context, View view) {
    DisplayMetrics displayMetrics = new DisplayMetrics();
    if (context != null) {
        ((Activity) context).getWindowManager().getDefaultDisplay()
                .getMetrics(displayMetrics);
        view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
        view.measure(displayMetrics.widthPixels, displayMetrics.heightPixels);
        view.layout(0, 0, displayMetrics.widthPixels,
                displayMetrics.heightPixels);
        view.buildDrawingCache();
        Bitmap bitmap = Bitmap.createBitmap(view.getMeasuredWidth(),
                view.getMeasuredHeight(), Bitmap.Config.ARGB_8888);

        Canvas canvas = new Canvas(bitmap);
        view.draw(canvas);
        return bitmap;
    }
    return null;
}

goodluck with that it was a lot of pain.
