Android SearchView在片段中不工作

我正在尝试实现一个searchview，它只在一个片段中需要。它将在listview上过滤

                    //remove selected item from the list of sales parts to choose from
                    listofOrderSelectedArray.remove(arrayPosition);

    mListView.setAdapter(adapter);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_sales_parts, container, false);
}
}

我已将上述代码放在“OnActivityCreated”中。我在这一行的setOnQueryTextListener上遇到一个错误。我已尝试将“this”更改为getActivity和getView，但均未解决问题。

更改onCreateView。。。像

并从onActivityCreated中删除所有代码。。。。并移动到onCreateView…

为什么不使用下面的searchView以及链接中的listview过滤器

发布您的片段代码…添加片段-谢谢，但您为什么在onActivityCreated中添加代码。。将所有代码从onActivityCreated移动到onCreateView…发布您的片段代码…添加片段-谢谢但为什么在onActivityCreated中添加代码。。将所有代码从onActivityCreated移动到onCreateView…谢谢，但这仍然会在这一行mSearchView.setOnQueryTextListenerthis上引发错误；表示它不能应用于android.View。view@user2029541应用像Internal class/或@user2029541这样的接口你应该在你的片段中实现SearchView.OnQueryTextListener这就是我想我必须要做的，我想片段是为了让开发更容易：/。谢谢M D。我会试试的。谢谢，但这仍然会在这行mSearchView.setOnQueryTextListenerthis上抛出一个错误；表示它不能应用于android.View。view@user2029541应用像Internal class/或@user2029541这样的接口你应该在你的片段中实现SearchView.OnQueryTextListener这就是我想我必须要做的，我想片段是为了让开发更容易：/。谢谢医学博士，我会试试的。
