PreferenceFragment界面透明问题

PreferenceFragment界面默认是透明的

而其布局代码框架为 <PreferenceScreen> ... </PreferenceScreen>，背景色及透明度属性设置无效，可通过代码中setBackGroundResource实现，代码如下：

public class XXXFragment extends PreferenceFragment implements OnClickListener {

	@Override
	public void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
	    addPreferencesFromResource(R.layout.note_preference_fragment);
	    getPreferenceManager().setSharedPreferencesName("mysetting");
	}

	@Override
	 public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen,
	   Preference preference) {
	  return true;
	 }

	@Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
		View view = super.onCreateView(inflater, container, savedInstanceState);
        view.setBackgroundResource(R.color.white);
		return view;
	}
}
