fragment中使用recycleView报nullpoint错误

报错代码一直提示是recycleView.setAdapter出错空指针错误一般为变量名没有实例化造成的查看了一下代码 adapter明显有实例化为何会没有实例化呢突然想到我的实例化代码写在了fragment的onCreatAr()中，由于并activity此时并未create，所以parent.getContex自然无法获取context。想到此，将setAdapter移到onActivityCreat()中去，问题马上得以解决。

public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub<pre name="code" class="java">

super.onActivityCreated(savedInstanceState);Bmob.initialize(getActivity(), Constants.Bmob_APPID);initViews();initListeners();initData();}

<pre name="code" class="java">	public void initData() {MyTopicAdapter adapter = new MyTopicAdapter();mytopicview.setItemAnimator(new DefaultItemAnimator());mytopicview.setLayoutManager(new LinearLayoutManager(getActivity()));mytopicview.setAdapter(adapter);}
