how to include custom title view with in AlertDialog in android?

how can i include custom titlebar in alertDialog?I know android sdk provide setCustomTitle method but it does'not work

edit:

    AlertDialog alert = new AlertDialog.Builder(this).setTitle("Test").setMessage("hello").show();
    View view=alert.getLayoutInflater().inflate(R.layout.titlebar, null);
    alert.setCustomTitle(view);

but above code is not working

NOTE : I am not looking for custom dialog box but only want to makes its title layout custom..Like below

you should not use the .show method with the first line, use the following code it works:

AlertDialog.Builder alert = new AlertDialog.Builder(this);
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.titlebar, null);
alert.setCustomTitle(view);
alert.setMessage("helo");
alert.show();
