【问题描述】：

我已经尝试了所有方法，但没有任何效果...请提供任何解决方案。如果我使用 listview 它可以完美运行，但在回收站视图上我会遇到错误。

代码如下

首页片段

    recyclerViewOne = view.findViewById(R.id.recyclerViewOne);
    collectionReference = firebaseFirestore.collection("Trending songs");
    recyclerViewOne.setHasFixedSize(true);
    recyclerViewOne.setLayoutManager(new 
    LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL,false));
    mUpload = new ArrayList<>();
    gridViewHolder = new GridViewHolder(getActivity(), mUpload, new 
    GridViewHolder.ItemClickListeners() {
        @Override
        public void onClicke(GridModel model, int post) {
            ((DashboardActivity) getActivity()).method();
            ((DashboardActivity) getActivity()).playO(post);

        }
    });
    recyclerViewOne.setAdapter(gridViewHolder);

我需要帮助

【问题讨论】：

请分享 GridViewHolder 类
onClick 没有 e

【解决方案1】：

根据命名，您正在尝试将 ViewHolder 设置为回收器的适配器。如果是这种情况，那么您应该以正确的方式实现它：扩展 RecyclerView.Adapter 并将该适配器添加到回收器视图的自定义适配器

这是 GridViewHolder

公共类 GridViewHolder 扩展 RecyclerView.Adapter {

Context context;
List<GridModel> gridModels;
private ItemClickListeners listeners;
private int selected;

@NonNull
@Override
public SongsAdapterViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(context).inflate(R.layout.grid_item, parent,false);

    return new SongsAdapterViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull SongsAdapterViewHolder holder, int position) {

    GridModel gridModel = gridModels.get(position);
    holder.mDesc.setText(gridModel.getmDesc());
    holder.mTitle.setText(gridModel.getmTitle());
    String duration = Utility.convertion(Long.parseLong(gridModel.getDuration()));
    Glide.with(context).load(gridModel.imageurl).into(holder.imageurl);
    holder.bind(gridModel, listeners);
}

public GridViewHolder(Context context, List<GridModel> gridModels, ItemClickListeners listeners) {
    this.context = context;
    this.gridModels = gridModels;
    this.listeners = listeners;
}

@Override
public int getItemCount() {

    return gridModels.size();
}
public class SongsAdapterViewHolder extends RecyclerView.ViewHolder{

    TextView mTitle, mDesc;
    ImageView imageurl;

    public SongsAdapterViewHolder(@NonNull View itemView) {
        super(itemView);
        mTitle = itemView.findViewById(R.id.gridTitle);
        mDesc= itemView.findViewById(R.id.gridMusician);
        imageurl  = itemView.findViewById(R.id.gridImageView);
    }

    public void bind(final GridModel gridModel, final ItemClickListeners listeners) {
        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                listeners.onClicke(gridModel, getAdapterPosition());
            }
        });
    }
}

public interface ItemClickListeners {
    void onClicke(GridModel model, int post);
}

public int getSelected() {
    return selected;
}

public void setSelected(int selected) {
    this.selected = selected;
}

}
