Firebase UI Recyclerview OnClick不起作用，尝试了所有操作。这不是重复的问题，请]] <<

Question

我正在尝试在Android应用中添加Firebase Recyclerview。当我添加时，所有数据都可以从Firestore中正常获取，但是在处理onClick事件时，它根本不起作用。

我关注的事情：

添加了带有方法的接口。

我的T​​ipsActivity.java中的实现接口

这里是代码：

TipsActivity.java

import androidx.appcompat.app.AppCompatActivity;
import androidx.paging.PagedList;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;

import android.os.Bundle;
import android.widget.Toast;

import android.util.Log;
import com.firebase.ui.firestore.paging.FirestorePagingOptions;
import com.google.firebase.firestore.FirebaseFirestore;
import com.google.firebase.firestore.Query;



public class TipsActivity extends AppCompatActivity implements FirestoreTipsAdapter.OnListItemClick {

   FirestoreTipsAdapter firestoreTipsAdapter;
    FirebaseFirestore firebaseFirestore;
    RecyclerView recyclerView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tips);

    firebaseFirestore = FirebaseFirestore.getInstance();
    recyclerView = findViewById(R.id.list);

    Query query = firebaseFirestore.collection("DailyTips").document("MyTips").collection("Tips");

    PagedList.Config config = new PagedList.Config.Builder()
            .setInitialLoadSizeHint(10)
            .setPageSize(5)
            .build();

    FirestorePagingOptions<TipsModel> firestorePagingOptions = new FirestorePagingOptions.Builder<TipsModel>()
            .setLifecycleOwner(this)
            .setQuery(query,config,TipsModel.class)
            .build();

    firestoreTipsAdapter = new FirestoreTipsAdapter(firestorePagingOptions,this,this);

       recyclerView.setHasFixedSize(true);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(firestoreTipsAdapter);


}

@Override
public void onItemClick() {
    Toast.makeText(this, "Show up bruh!", Toast.LENGTH_SHORT).show();
Log.d("AT_LEAST","You should work");
}
}

这是我的：

FirestoreTipsAdapter.java

package com.mycompany.company;


import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;

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

import com.firebase.ui.firestore.paging.FirestorePagingAdapter;
import com.firebase.ui.firestore.paging.FirestorePagingOptions;

public class FirestoreTipsAdapter extends FirestorePagingAdapter<TipsModel, FirestoreTipsAdapter.TipsViewHolder> {

    private OnListItemClick onListItemClick;
    Context context;

    public FirestoreTipsAdapter(@NonNull FirestorePagingOptions<TipsModel> options,OnListItemClick onListItemClick,Context context) {
        super(options);
        this.onListItemClick = onListItemClick;
        this.context = context;
    }

    @Override
    protected void onBindViewHolder(@NonNull TipsViewHolder holder, int position, @NonNull TipsModel model) {
        holder.title.setText(model.getTitle());
        holder.description.setText(model.getDescription());

    }

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

    public class TipsViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView title,description;


        public TipsViewHolder(@NonNull View itemView) {
            super(itemView);
            title = itemView.findViewById(R.id.list_title);
            description = itemView.findViewById(R.id.list_desc);

            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(context, "Are you working bro?", Toast.LENGTH_SHORT).show();
                }
            });

        }

        @Override
        public void onClick(View v) {
            onListItemClick.onItemClick();
        }
    }
    public interface OnListItemClick{
        void onItemClick();
    }
}

这是list_item.xml的代码

<?xml version="1.0" encoding="utf-8"?>

<androidx.cardview.widget.CardView android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        android:layout_height="wrap_content"
        android:layout_marginTop="4dp"
        android:text="Description" />

    </LinearLayout>

        android:layout_height="100dp"
        android:src="@drawable/curveshape"
        android:layout_gravity="end|bottom"
        android:layout_marginBottom="-30dp"
        android:alpha="0.2"
        />

    <ImageView

        android:layout_marginRight="25dp"
        android:alpha="0.2"
        />


</androidx.cardview.widget.CardView>

注意：我能够从Firestore提取数据，它可以正确显示数据。

请帮忙。我遵循了堆栈溢出的所有其他答案。 我正在尝试在Android应用中添加Firebase Recyclerview。当我添加时，所有数据都可以从Firestore中正常获取，但是在处理onClick事件时，它根本无法工作。 ...

在给定的设置中，OnClickListener被设置在ViewHolder的itemView上，它将作为其布局中的根View，即CardView。但是，在clickable上设置的focusable和LinearLayout属性会导致它首先获取触摸事件，因此它基本上是在CardView处理它们以响应单击之前拦截它们。但是，LinearLayout上没有侦听器，因此没有任何反应。
