PreferenceFragment background color

问题

I am using a PreferenceFragment (without a ListView), but am unable to set the background color, and it seems to be transparent.

How can I set the background color to white with PreferenceFragment?

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));
}

try this.

  @Override
  public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        getListView().setBackgroundColor(Color.BLACK);
  }
