我正在设置style.xml的活动背景,如下所示

<item name="android:windowBackground">@color/very_light_gray</item>

现在只有一个特定的片段我想设置背景透明,我无法做到尝试下面的片段代码片段对我来说不起作用

@Override
 public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {

// create ContextThemeWrapper from the original Activity Context with the custom theme
final Context contextThemeWrapper = new ContextThemeWrapper(getActivity(),R.style.yourCustomTheme);

// clone the inflater using the ContextThemeWrapper
LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper);

// inflate the layout using the cloned inflater,not default inflater
return localInflater.inflate(R.layout.yourLayout,container,false);
}

知道怎么做吗？
