片段中的 RecyclerView OnclickListener

Question

我正在尝试在片段中的 recyclyerView 上设置点击侦听器我不知道如何在片段中调用 activity 我只知道在构造函数中解析上下文，但是 clickListener 没有这样做之前，我尝试过但它根本不起作用

public class RecView extends RecyclerView.Adapter<RecView .SuggestedViewHolder>
{
    ArrayList<SuggestedModel> suggestedModels;
    final private RecyclerViewClickListener clickListener;

    public RecView(ArrayList<SuggestedModel> suggestedModels_items, RecyclerViewClickListener clickListener)
    {
        this.suggestedModels_items = suggestedModels_items;
        this.clickListener = clickListener;
    }

    @Override
    public void onBindViewHolder(@NonNull SuggestedViewHolder holder, int position)
    {
        SuggestedModel suggestedModel=suggestedModels.get(position);
        holder.image.setImageResource(suggestedModel.getImage());
        holder.title.setText(suggestedModel.getTitle());
    }

    @NonNull
    @Override
    public SuggestedViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType)
    {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_recview_suggested_item,parent,false);
        final SuggestedViewHolder suggestedViewHolder = new SuggestedViewHolder(view);
        return suggestedViewHolder;
    }


    @Override
    public int getItemCount()
    {
        return suggestedModels.size();
    }

    public class SuggestedViewHolder extends RecyclerView.ViewHolder
    {

        CircleImageView image;
        TextView title;

        public SuggestedViewHolder(@NonNull View itemView)
        {
            super(itemView);
            image = itemView.findViewById(R.id.suggestedImage);
            title = itemView.findViewById(R.id.suggestedTitle);
        }
    }


//////////

this is what i called in the fragment 

   

    private void getSuggestedData()
    {

        rec_TopMost.setHasFixedSize(true);
        rec_TopMost.setLayoutManager(new LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL,false));
        suggestedModels.add(new SuggestedModel(R.drawable.s1,"Movie1"));
        suggestedModels.add(new SuggestedModel(R.drawable.s2,"Movie2"));
        suggestedModels.add(new SuggestedModel(R.drawable.s3,"Movie3"));
        suggestedModels.add(new SuggestedModel(R.drawable.s4,"Movie4"));
        suggestedModels.add(new SuggestedModel(R.drawable.s5,"Movie5"));
        suggestedModels.add(new SuggestedModel(R.drawable.s6,"Movie6"));
        suggestedModels.add(new SuggestedModel(R.drawable.s7,"Movie7"));
        suggestedModels.add(new SuggestedModel(R.drawable.s8,"Movie8"));
        suggestedModels.add(new SuggestedModel(R.drawable.s9,"Movie9"));

        RecView= new RecView( suggestedModel,(RecyclerViewClickListener) getContext());
        rec_TopMost.setAdapter(RecView);

    }

我该怎么做我试了很多东西都行不通

{

    RecView= new RecView( suggestedModels,  getContext());
            rec_TopMost.setAdapter(RecView);
}

如果我这样做，它会显示红线。在 getContext();

下

这不是 Activity 或 Fragment 的问题，您的 RecView 将 RecyclerViewClickListener 作为第二个参数，让您的 Fragment 实现此接口就像Activity 确实
