android - 在 onCreateView() fragment 中设置动态布局

Question

我用，

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

          MyView myView = new MyView(getActivity());
          myView.addViews(getViews());
          return myView;
        }

我知道 public void onActivityCreated (Bundle savedInstanceState){} 在 onCreateView(); 之后调用

我将需要 onCreateView() 中的上下文来扩充自定义布局。如何在 onActivityCreated() 之前一直获取有效上下文(使用 getActivity())？

可能的解决方案:

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

              view = inflater.inflate(R.layout.fragment, container, false); //Contains empty RelativeLayout       
              return view;
            }


    //Now that we have activity, create custom views and add it to the empty container
    public void onActivityCreated (Bundle savedInstanceState){
      RelativeLayout layout = (RelativeLayout)view.findViewById(R.id.layout);
      MyView myView = new MyView(getActivity());
      layout.add(myView); 
    }

但是这个方法增加了一个额外的 View 层次结构。

您可以使用与 LayoutInflater 关联的 Context 对象:

MyView myView = new MyView( inflater.getContext() );
