Question

我有一些奇怪的Stackoverflower，它在我使用的Fragment的onCreateView（）方法中抛出。

正如您在此图片中看到的那样，这是它破坏的方法。第一个TODO应该是错误的来源。

我不知道该行有什么问题：

  view = inflater.inflate(R.layout.activity_chat, container, false); //it breaks here

我很高兴听到任何人发出任何声响。

编辑：这是我在初始错误后得到的另一个奇怪的错误报告：

我认为你在onCreateView中做了很多事情 - 我的建议是你移动onActivityCreated(Bundle savedInstanceState)中的其余代码。将onCreateView更改为：

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {      
        View rootView = inflater.inflate(R.layout.activity_chat, container, false);     
        return rootView;
    }

然后您可以将其余代码移至onActivityCreated 。创建主机活动时，在onCreateView()方法之后调用此方法。已创建活动和片段实例以及活动的视图层次结构。此时，可以使用findViewById()方法访问视图。

在膨胀Fragment时出现StackoverflowError
