Question

我正在我的适配器中实现onclicklistener和onlongclicklistener以获取我的回收站视图和在我的适配器类的构造函数中插入Context后，我的recyclerview不会显示。下面显示了我的适配器类和活动onCreate

ListingNearbyAdapter.Class

public class ListingNearbyAdapter extends RecyclerView.Adapter<ListingNearbyAdapter.ListingNearbyViewHolder>{
    ArrayList<ListingNearby> listings = new ArrayList<ListingNearby>();
    Context context;

    public ListingNearbyAdapter(ArrayList<ListingNearby> listings, Context context){
        this.listings = listings;
        this.context = context;
    }

    @Override
    public ListingNearbyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.listing_nearby_row_layout,parent,false);
        ListingNearbyViewHolder listingNearbyViewHolder = new ListingNearbyViewHolder(view, context, listings);

        return listingNearbyViewHolder;
    }

    @Override
    public void onBindViewHolder(ListingNearbyViewHolder holder, int position) {
        ListingNearby list = listings.get(position);
        holder.property_name.setText("Property Name:  " + list.getProperty_name());
        holder.type.setText("Property Type:  " + list.getType());
        holder.price.setText("Price:  PHP " + list.getPrice());
        holder.distance.setText("Distance:  " + String.valueOf(list.getDistance()) + " km");
    }

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

    public static class ListingNearbyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener{
        TextView property_name, type, price, distance;
        ArrayList<ListingNearby> listings = new ArrayList<ListingNearby>();
        Context context;

        public ListingNearbyViewHolder(View view, Context context, ArrayList<ListingNearby> listings){
            super(view);
            this.listings = listings;
            this.context = context;
            view.setOnClickListener(this);
            view.setOnLongClickListener(this);

            property_name = (TextView) view.findViewById(R.id.ln_property_name);
            type = (TextView) view.findViewById(R.id.ln_type);
            price = (TextView) view.findViewById(R.id.ln_price);
            distance = (TextView) view.findViewById(R.id.ln_distance);
        }

        @Override
        public void onClick(View v) {
            int position = getAdapterPosition();
            ListingNearby listingNearby = this.listings.get(position);

            Intent intent = new Intent(this.context, PropertyDetails.class);
            intent.putExtra("property_id", listingNearby.getProperty_id());
            this.context.startActivity(intent);
        }

        @Override
        public boolean onLongClick(View v) {
            return false;
        }
    }
}

OnCreate中：

recyclerView = (RecyclerView) findViewById(R.id.ln_recycler_view);
                    layoutManager = new LinearLayoutManager(this);
                    recyclerView.setLayoutManager(layoutManager);
                    recyclerView.setHasFixedSize(true);
                    adapter = new ListingNearbyAdapter(list, this);
                    recyclerView.setAdapter(adapter);

我不知道错误在哪里，提前谢谢。

在实现onClickListener后，RecyclerView不会设置适配器
