问题描述
*** java.lang.classCastException: com.makeramen.roundedimageview.RoundedImageView 无法转换为 androidx.recyclerview.widget.RecyclerView***
片段java代码-
public class HomeFragment extends Fragment {
RecyclerView storyRv;
ArrayList<StoryModel> list;
public HomeFragment() {
// required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_home,container,false);
storyRv = view.findViewById(R.id.storyRV);
list = new ArrayList<>();
list.add(new StoryModel(R.drawable.img_placeholder,R.drawable.vdocam_png,R.drawable.my_dp,"Abhishek"));
list.add(new StoryModel(R.drawable.img_placeholder,"Abhishek"));
StoryAdapter adapter = new StoryAdapter(list,getContext());
linearlayoutmanager linearlayoutmanager = new linearlayoutmanager(getContext(),linearlayoutmanager.HORIZONTAL,false);
storyRv.setLayoutManager(linearlayoutmanager);
storyRv.setnestedScrollingEnabled(false);
storyRv.setAdapter(adapter);
return view;
}
}
适配器 -
public class StoryAdapter extends RecyclerView.Adapter<StoryAdapter.viewHolder>{
ArrayList<StoryModel> list;
Context context;
public StoryAdapter(ArrayList<StoryModel> list,Context context) {
this.list = list;
this.context = context;
}
@NonNull
@Override
public viewHolder onCreateViewHolder(@NonNull ViewGroup parent,int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.srtory_rv_design,parent,false);
return new viewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull viewHolder holder,int position) {
StoryModel model = list.get(position);
holder.storyIv.setimageResource(model.getStory());
holder.profile.setimageResource(model.getProfile());
holder.liveIv.setimageResource(model.getLiveIv());
holder.userName.setText(model.getUserName());
}
@Override
public int getItemCount() {
return list.size();
}
public class viewHolder extends RecyclerView.ViewHolder{
ImageView storyIv,profile,liveIv;
TextView userName;
public viewHolder(@NonNull View itemView) {
super(itemView);
storyIv = itemView.findViewById(R.id.story_dg);
profile = itemView.findViewById(R.id.profile_image_Dg);
liveIv = itemView.findViewById(R.id.LiveIv);
userName = itemView.findViewById(R.id.usersName_Iv);
}
}
}
