Dcloud不支持fragment以webview方式集成吗？

找不到官方任何相关的资料，Demo里只有activity+webview方式集成的。用fragment如何集成？

以下代码有什么问题吗?

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
if (null == view) {
myContainer = new LinearLayout(mContext);
view = inflater.inflate(R.layout.layout_fragment_circle, null);
ll_circle = (LinearLayout) view.findViewById(R.id.ll_circle);
fl_web = (FrameLayout) view.findViewById(R.id.fl_web);

        view.setMinimumHeight(((WindowManager) getActivity()  
                .getSystemService(Context.WINDOW_SERVICE))  
                .getDefaultDisplay().getHeight());  
        view.setMinimumWidth(((WindowManager) getActivity()  
                .getSystemService(Context.WINDOW_SERVICE))  
                .getDefaultDisplay().getWidth());  
        if (mEntryProxy == null) {     
        WebMode wm = new WebMode(this.getActivity(), fl_web);  
        mEntryProxy = EntryProxy.init(this.getActivity(), wm);  
            mEntryProxy.onCreate(savedInstanceState,  
                    SDK.IntegratedMode.WEBVIEW, null);  
        }  
        myContainer.addView(view);  
    } else {  
        myContainer.removeAllViews();  
        myContainer = new LinearLayout(getActivity());  
        myContainer.addView(view);  
    }  
    return myContainer;  

}

显示不出来。
