Android Preference, what resources does it use, and where to find the source?
===

I am using this for my application so the user can set the options for the application.
In one part of it, I need to override the default content and add something extra below the title and summary.

Overriding the default looks is pretty easily achieved by the following code

    PreferenceScreen screen7 = getPreferenceManager().createPreferenceScreen(this);
    screen7.setKey("night_options_time");
    screen7.setSelectable(false);
    screen7.setLayoutResource(R.layout.test);


However, this ofcourse loads a xml file you have to create yourself. The layout, dimension and text parameters are not that hard to mimic, but the horizontal row borders I can't seem to find. I don't want to create one myself, I'd rather stick to the default resources for future compatibility. So, I guess the questions is: where can I find them?

I found the resources in the platforms folders, but anything named preferences there is related to the settings screen/ app, which is different.

I am talking about these `Preferences`:
