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

Before write dialog.show(), write:

int divierId = dialog.getContext().getResources().getIdentifier("android:id/titleDivider",   null, null);
View divider = dialog.findViewById(divierId);
if(divider!=null){
divider.setBackgroundColor(getResources().getColor(R.color.transparent));}

In colors.xml:

#00000000
