PreferenceFragment background color

This question was also answered here

Adding the following code to your PreferenceFragment will let you add a background color, image, etc.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = super.onCreateView(inflater, container, savedInstanceState);
    view.setBackgroundColor(getResources().getColor(android.R.color.your_color));

    return view;
}

Also you can do something like changing the view's background in the onViewCreated() method.

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    view.setBackgroundColor(getResources().getColor(R.color.YOUR_COLOR));
}
