RecyclerView点击卡片无法启动新Activity问题求助

我正在实现点击RecyclerView中的卡片打开AdminProspectsDetails Activity查看潜在客户（Prospect）详情的功能，但点击卡片时没有任何Activity启动。目前仅需验证能否打开新页面，还未在详情页填充数据，不清楚问题出在哪里。相关代码如下：

Prospect数据类 #

var ProspectList = mutableListOf<Prospect>()
val PROSPECT_ID_EXTRA = "ProspectExtra"
data class Prospect(
    val categorie: String,
    var email: String,
    var nom: String,
    var siret: String,
    var tel: String,
    var type: String,
    var user: String,
    var status: String
)

CardClickListener接口 #

package ml2v.demenagement.all.android.data.model

interface CardClickListener{
    fun onClick(prospect: Prospect)
}

AdminProspectsDetails类 #

package ml2v.demenagement.all.android.ui.interfaces

import android.os.Bundle
import androidx.activity.ComponentActivity
import ml2v.demenagement.all.android.data.model.Prospect
import ml2v.demenagement.app.android.R


class AdminProspectsDetails:ComponentActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_admin_prospect_details)
        actionBar?.hide()


    }
}

核心问题 #

点击无响应的根本原因是：每次数据加载或筛选时，都重新创建了ProspectAdminAdapter实例，但没有绑定点击监听器。初始创建的Adapter虽然设置了setCardClickListener(this)，但后续被无监听器的新Adapter覆盖，导致卡片点击事件无法触发。

修复步骤 #

1. 全局保存Adapter实例：避免重复创建Adapter，仅更新数据源
2. 数据源变化时刷新UI：调用Adapter的notifyDataSetChanged()更新，而非重新创建Adapter
3. 确保所有Adapter实例都绑定监听器：如果必须创建新Adapter，一定要调用setCardClickListener(this)

关键修改代码 #

修改AdminProspects类的核心逻辑

class AdminProspects() : ComponentActivity(), CardClickListener {

    private lateinit var recyclerView: RecyclerView
    private val prospectList = mutableListOf<Prospect>()
    private var filteredList = mutableListOf<Prospect>()
    // 全局保存Adapter实例
    private lateinit var adapter: ProspectAdminAdapter

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_admin_prospects)
        actionBar?.hide()

        recyclerView = findViewById<RecyclerView>(R.id.prospects_views)
        // 初始化Adapter并绑定监听器
        adapter = ProspectAdminAdapter(prospectList)
        adapter.setCardClickListener(this)
        recyclerView.adapter = adapter
        recyclerView.itemAnimator = SlideInUpAnimator()

        // ... 开关定义部分保留 ...

        // BDD数据加载部分修改
        val db = Firebase.firestore
        val prospectsCollection = db.collection("demenagement")

        prospectsCollection.get().addOnSuccessListener { documents ->
            for (document in documents) {
                val prospect = document.data
                val categorie = prospect["categorie"] as String
                val email = prospect["mail"] as String
                val nom = prospect["nom"] as String
                val siret = prospect["siret"] as String
                val tel = prospect["tel"] as String
                val type = prospect["type"] as String
                val status = prospect["status"] as String
                val usersuid = prospect["users"] as String

                val usersCollection = db.collection("users")
                usersCollection.document(usersuid).get().addOnSuccessListener { userDoc ->
                    val userName = userDoc.getString("nom").toString()
                    val newProspect = Prospect(categorie, email, nom, siret, tel, type, userName, status)
                    prospectList.add(newProspect)
                    // 仅刷新UI，不重建Adapter
                    adapter.notifyDataSetChanged()
                }
            }
        }

        // 开关筛选逻辑修改示例（其他开关同理）
        switchWaiting.setOnCheckedChangeListener { _, isChecked ->
            isWaitingSelected = isChecked
            switchInProgress.isClickable = false
            switchValidate.isClickable = false

            if (isChecked) {
                filteredList = prospectList.filter { it.status == "En attente" } as MutableList<Prospect>
                // 创建新Adapter时必须绑定监听器
                adapter = ProspectAdminAdapter(filteredList)
                adapter.setCardClickListener(this)
                recyclerView.adapter = adapter
                if(filteredList.isEmpty()){
                    Toast.makeText(this, "Liste vide pour le moment", Toast.LENGTH_SHORT).show()
                }
            } else {
                // 恢复原列表时同样绑定监听器
                adapter = ProspectAdminAdapter(prospectList)
                adapter.setCardClickListener(this)
                recyclerView.adapter = adapter
                switchInProgress.isClickable = true
                switchValidate.isClickable = true
            }
        }

        // ... 其他开关逻辑按上述方式修改 ...
    }

    override fun onClick(prospect: Prospect) {
        val intent = Intent(this, AdminProspectsDetails::class.java)
        intent.putExtra("email", prospect.email)
        startActivity(intent)
    }
}

更优方案：给Adapter添加更新数据源方法

在ProspectAdminAdapter中添加以下方法，避免重复创建Adapter实例：

fun updateData(newList: MutableList<Prospect>) {
    prospectList.clear()
    prospectList.addAll(newList)
    notifyDataSetChanged()
}

之后在筛选逻辑中只需调用：

adapter.updateData(filteredList)

无需重新创建Adapter，效率更高且不会丢失监听器绑定。
