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.

Answer 1

This one is tested on some 4.x devices:

    TextView title = (TextView)getWindow().getDecorView().findViewById(android.R.id.title);
    ((ViewGroup)title.getParent()).getChildAt(1).setVisibility(View.GONE);
