跟着b站大锯视频写的，不知道为什么点击事件无响应，点了item后会显示下列语句

去网上查了方法，在item的根布局加了下面一句代码

android:descendantFocusability="blockDescendants"

如下图

加在了item.xml的根元素上，不过小白俺不知道加的位置对不对，干脆给嵌套有RecycleView的LinearLayout和ScrollView也加了上面那句代码，如下图，依旧没解决（嵌套有RecycleView的LinearLayout也是位于一个ScorllView里面的）

求大佬相助qaq

适配器代码如下

package com.example.animaland.Adapters;

import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;

import com.example.animaland.R;
import com.example.animaland.room.ShellStudyRoom;
import com.example.animaland.room.room;

import java.util.List;

public abstract class RecycleViewBaseAdapter extends RecyclerView.Adapter<RecycleViewBaseAdapter.InnerHolder> {

    private final List<room> mdata;
    private onItemClickListener monItemClickListener;

    public RecycleViewBaseAdapter(List<room> roomData){
        this.mdata=roomData;
    }

    @NonNull
    @Override
    public RecycleViewBaseAdapter.InnerHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        
        View view=getSubView(parent,viewType);
        return new InnerHolder(view);
    }

    protected abstract View getSubView(ViewGroup parent,int ViewType);

    @Override
    public void onBindViewHolder(@NonNull RecycleViewBaseAdapter.InnerHolder holder, int position) {
        //绑定holder
        holder.setData(mdata.get(position),position);
    }

    @Override
    public int getItemCount() {
        if(mdata!=null)
            return mdata.size();
        return 0;
    }

    public void setOnItemClickListener(onItemClickListener listener) {
        //设置一个监听
        this.monItemClickListener=listener;
    }

    public interface onItemClickListener{
        void onItemClick(int position);
    }

    public class InnerHolder extends RecyclerView.ViewHolder {

        private TextView idView;
        private TextView roomNameView;
        private TextView memberNumberView;
        private ImageView imageView;
        private int mposition;


        public InnerHolder(@NonNull View itemView) {
            super(itemView);

            //找到条目的控件
            idView= itemView.findViewById(R.id.room_id);//房间ID
            roomNameView= itemView.findViewById(R.id.room_name);//房间名字
            memberNumberView= itemView.findViewById(R.id.room_memberNumber);//房间人数
            imageView=itemView.findViewById(R.id.room_background);

            itemView.setOnClickListener(view -> {
                if (monItemClickListener != null) {
                    monItemClickListener.onItemClick(mposition);
                }
            });  

        }

        public void setData(room room,int position) {

            this.mposition=position;

            idView.setText("ID: "+room.id);
            roomNameView.setText(room.roomName+"");
            memberNumberView.setText(room.roomMember+"/4");
            imageView.setImageResource(room.icon);
        }

    }
}

补充下Activity里的代码

package com.example.animaland.room;

import android.app.AppComponentFactory;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.ScrollView;

import com.example.animaland.Adapters.ListViewAdapter;
import com.example.animaland.Adapters.RecycleViewBaseAdapter;
import com.example.animaland.MainActivity;
import com.example.animaland.R;


import java.util.ArrayList;
import java.util.List;

public class TreeHouseStudyRoom extends AppCompatActivity{

    private RecyclerView mlist;
    private List<room> mroomList;
    private RecycleViewBaseAdapter madapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.treehouse_study_room);
        mlist=findViewById(R.id.rv_treehouse);
        
        initData();//模拟数据
        showGrid(true,false);
    }

    //模拟数据
    private void initData() {

        mroomList= new ArrayList<>();//创建房间数据集合

        for(int i=0;i<8;i++){
            room roomData=new room();
            roomData.id=i;
            roomData.roomName="珊迪的树屋";
            roomData.roomMember=i%4+1;
            roomData.icon=roomPictures.roomPics[1];//加载图片
            mroomList.add(roomData);//将房间数据添加到房间数据集合中
        }

    }

    private void initListener() {
        
       madapter.setOnItemClickListener(position -> {
            //当条目被点击后展示下列效果
            Toast.makeText(TreeHouseStudyRoom.this,"ID "+position+" 被点击了",Toast.LENGTH_SHORT).show();
        });
    }

    private void showGrid(boolean isVertical,boolean isReverse) {
        //设置布局管理器
        GridLayoutManager layoutManager=new GridLayoutManager(this,3);

        //设置水平还是垂直
        layoutManager.setOrientation(isVertical?GridLayoutManager.VERTICAL:GridLayoutManager.HORIZONTAL);

        //设置正向还是反向
        layoutManager.setReverseLayout(isReverse);
        mlist.setLayoutManager(layoutManager);

        //创建适配器Adapter
        madapter=new GridViewAdapter(mroomList);

        //设置适配器
        mlist.setAdapter(madapter);

        //创建条目的点击事件
        initListener();
    }
}
