Styling titleDivider in Dialog

Question

I am wondering how it is possible to get rid of (or change color) titleDivider in Dialog. It is a blue line below dialog title shown on honeycomb+ devices.

You need to implement

myDialog = builder.create();
myDialog.setOnShowListener(new OnShowListenerMultiple());

//----------------------------
//Function to change the color of title and divider of AlertDialog
public static class OnShowListenerMultiple implements DialogInterface.OnShowListener {
    @Override
    public void onShow( DialogInterface dialog ) {
        if( !(dialog instanceof Dialog) )
            return;

        Dialog d = ((Dialog) dialog);
        final Resources resources = d.getContext().getResources();
        final int color = AppUtility.getColor( resources, R.color.defaultColor );

        try {
            int titleId = resources.getIdentifier( "android:id/alertTitle", null, null );
            TextView titleView = d.findViewById( titleId );
            titleView.setTextColor( color );
        }
        catch( Exception e ) {
            Log.e( "XXXXXX", "alertTitle could not change color" );
        }

        try {
            int divierId = resources.getIdentifier( "android:id/titleDivider", null, null );
            View divider = d.findViewById( divierId );
            divider.setBackgroundColor( color );
        }
        catch( Exception e ) {
            Log.e( "XXXXXX", "titleDivider could not change color" );
        }
    }
}
