单击CardView（onClickListener）后没有任何反应

Question

我正在编写一个酒店安卓应用程序... 我使用了来自Androidhive资源的cardview和recycleview ...

现在我想在每个项目上放置onClickListener，并为缩略图设置onClickListener ...

这是我的HotelListAdapter：

    package ir.homa;

import android.content.ClipData;
import android.content.Context;
import android.content.Intent;
import android.support.v7.widget.PopupMenu;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import com.bumptech.glide.Glide;

import java.util.List;
/**

public class HotelListAdapter extends RecyclerView.Adapter<HotelListAdapter.MyViewHolder> {

    private Context mContext;
    private List<HotelList> hotelList;


    public class MyViewHolder extends RecyclerView.ViewHolder {
        public TextView title, count;
        public ImageView thumbnail, overflow;

        public MyViewHolder(View view) {
            super(view);
            title = (TextView) view.findViewById(R.id.title);
            count = (TextView) view.findViewById(R.id.count);
            thumbnail = (ImageView) view.findViewById(R.id.thumbnail);
            overflow = (ImageView) view.findViewById(R.id.overflow);
        }
    }


    public HotelListAdapter(Context mContext, List<HotelList> hotelList) {
        this.mContext = mContext;
        this.hotelList = hotelList;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType)  {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.hotel_list, parent, false);


        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, int position) {
        final HotelList hotel = hotelList.get(position);
        holder.title.setText(hotel.getName());
        holder.count.setText(hotel.getNumOfRooms() + " اتاق");

        // loading hotel cover using Glide library
        Glide.with(mContext).load(hotel.getThumbnail()).into(holder.thumbnail);

        holder.overflow.setOnClickListener(new View.OnClickListener() {

        });
    }

    private void showPopupMenu(View view) {
        // inflate menu
        PopupMenu popup = new PopupMenu(mContext, view);
        MenuInflater inflater = popup.getMenuInflater();
        inflater.inflate(R.menu.hotel_list_menu, popup.getMenu());
        popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
        popup.show();
    }


    class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener {

        public MyMenuItemClickListener() {

        }

            switch (menuItem.getItemId()) {
                case R.id.action_add_favourite:

                    return true;
                case R.id.card:
                    Intent myIntent = new Intent(mContext, MashhadHoma1.class);
                    mContext.startActivity(myIntent);
                    Toast.makeText(mContext, "بزودی در دسترس قرار میگیرد!", Toast.LENGTH_SHORT).show();

                default:
            }
            return false;
        }


    }
    private Context context;

    public HotelListAdapter(Context context) {
        this.context = context;
    }
    public  class ViewHolder extends RecyclerView.ViewHolder {
        public View view;
        public ClipData.Item currentItem;

        public ViewHolder(View v) {
            super(v);
            view = (ImageView) view.findViewById(R.id.thumbnail);
            view.setOnClickListener(new View.OnClickListener() {
                @Override public void onClick(View v) {
        switch (view.getId()) {
            case R.mipmap.mashhad_homa1:
                Intent openThree = new Intent(context,MashhadHoma1.class);
                context.startActivity(openThree);
                break;





        }
                }
            });
        }
    }



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

}

我为HotelListAdapter中的onclickListener设置了一个Switch / case：

public  class ViewHolder extends RecyclerView.ViewHolder {
        public View view;
        public ClipData.Item currentItem;
 public ViewHolder(View v) {
            super(v);
            view = (ImageView) view.findViewById(R.id.thumbnail);
            view.setOnClickListener(new View.OnClickListener() {
                @Override public void onClick(View v) {
        switch (view.getId()) {
            case R.mipmap.mashhad_homa1:
                Intent openThree = new Intent(context,MashhadHoma1.class);
                context.startActivity(openThree);
                break;
        }
}
