java - 更改片段更改的主题

Question

我需要fragment动态更改主题，我尝试了这段代码，但它不起作用onCreate或onCreateView()

getActivity().setTheme(R.style.ActionMode);

我如何设置主题fragment？

Answer 1

在该onCreateView()方法中，您必须从中创建ContextThemeWrapper和扩展主题样式，如下所示：

@Override
public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
    //create ContextThemeWrapper from the original Activity Context with the custom theme
    Context context = new ContextThemeWrapper(getActivity(), R.style.your_Custom_Theme);
    //clone the inflater using the ContextThemeWrapper
    LayoutInflater localInflater = inflater.cloneInContext(context);
    //inflate using the cloned inflater, not the passed in default
    return localInflater.inflate(R.layout.your_layout, container, false);
}
