Java android.widget.FrameLayout无法强制转换为androidx.recyclerview.widget.recyclerview

我正在对我的recycler视图执行刷卡刷新功能，但它不断出现无法转换的错误

以下是我的XML：

announcement_recycler_view.xml

---

您正在膨胀一个

FrameLayout

并将其强制转换为

RecyclerView

，删除强制转换并使用

findViewById

查找您的

RecyclerView

因此，您的代码应该如下所示：

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

    View view = inflater.inflate(
            R.layout.announcement_recycler_view, container, false);
    announcementRecyclerView = view.findViewById(R.id.my_announcement_recycler_view);

    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity());
    announcementRecyclerView.setLayoutManager(layoutManager);

    //initializing the productlist
    announcementList = new ArrayList<>();

    // Session class instance
    session = new SharedPrefManager(getActivity());

    loadAnnouncement();

    return view;
}

public View onCreateView（布局、充气机、视图组容器、，
Bundle savedInstanceState）{
视图=充气机。充气(
R.layout.announcement\u recycler\u view，container，false）；
announcementRecyclerView=view.findviewbyd（R.id.my\u announcement\u recycler\u view）；
RecyclerView.LayoutManager LayoutManager=新的LinearLayoutManager（getActivity（））；
announcementRecyclerView.setLayoutManager（layoutManager）；
//初始化产品列表
announcementList=newarraylist（）；
//会话类实例
会话=新的SharedPrefManager（getActivity（））；
loadAnnouncement（）；
返回视图；
}

ClassCastException表示您错误地强制转换组件，即：您将TextView强制转换为ImageView

因此，请确保在初始化recyclerView时未使用FrameLayouts ID

在您的第一个片段中，您提供的XML表示RecyclerView的ID为my_announcement\u recycler\u view

但是在您的类中，您正在像这样初始化您的RecyclerView

 announcementRecyclerView = (RecyclerView) inflater.inflate(
                R.layout.announcement_recycler_view, container, false)

 announcementRecyclerView = (RecyclerView) inflater.inflate(
                R.layout.my_announcement_recycler_view, container, false)

应该是这样的

 announcementRecyclerView = (RecyclerView) inflater.inflate(
                R.layout.announcement_recycler_view, container, false)

 announcementRecyclerView = (RecyclerView) inflater.inflate(
                R.layout.my_announcement_recycler_view, container, false)

请发布您的AnnouncementFragment.java类及其布局。Thanks@Krishnasheladiya嗨，我已经发了。布局是公告_recycler _view.xml。谢谢

 announcementRecyclerView = (RecyclerView) inflater.inflate(
                R.layout.my_announcement_recycler_view, container, false)
