How to manage dividers in a PreferenceFragment?

Question

I started dealing with preferences in a PreferenceFragment. Here\'s what I have:

Had totally forgot about this question, will post an answer now to help others. I solved by moving my code in the onResume() method of the activity that hosts my PreferenceFragment. I think there are several other points at which you can recall a non-null ListView using findViewById(android.R.id.list).

public boolean mListStyled;

@Override
public void onResume() {
    super.onResume();
    if (!mListStyled) {
        View rootView = getView();
        if (rootView != null) {
            ListView list = (ListView) rootView.findViewById(android.R.id.list);
            list.setPadding(0, 0, 0, 0);
            list.setDivider(null);
            //any other styling call
            mListStyled = true;
        }
    }
}

You can probably get rid of the rootView check, but at the same time you might even want to check for list != null. I didn't face any NPE this way anyway.

So, setDivider(null) takes off the item-item dividers. I managed to add section dividers covering the full width of the screen by:

• Removing padding from list;
• Adding a custom preference in my XML:
