我正在尝试从NotificationListiner服务启动UI活动，然后在UI中，当用户单击“是”时：执行pendingIntent（）; else：完成（）
我试着用Dialog,AlertDialog来实现上面的功能，但是因为NotificationListiner是后台服务，所以它不起作用。
已尝试使用Gson
SbnContainer.kt

class SbnContainer {
    lateinit var notification: Notification
    lateinit var title: String
    lateinit var desc: String
    constructor(){
        Log.d("TAG", "Salaam")
    }
    constructor(notification: Notification, title:String, desc:String){
        this.notification = notification
        this.title= title
        this.desc = desc
    }
}

从NotificationService呼叫

var i = Intent(this,CAlertWindow::class.java)
    i.flags = Intent.FLAG_ACTIVITY_NEW_TASK
    val gson = Gson()
    var a = SbnContainer(sbn.notification, title, desc)
    val myJson = gson.toJson(a)
    i.putExtra("PACKAGE", myJson)
    startActivity(i)

从CAlertWindow(AppCompatActivity)接收

val gson = Gson()
        val ob: SbnContainer = gson.fromJson(intent.getStringExtra("PACKAGE"), SbnContainer::class.java)
        pendingIntent = ob.notification.contentIntent
        alertWindowLayoutBinding.alrTitle.text = ob.title
        alertWindowLayoutBinding.alrDesc.text = ob.desc
        Log.d("Abdx79/AlertWindow", "In Alert Window")
        alertWindowLayoutBinding.alrOpnB.setOnClickListener {
            pendingIntent.send()
        }
        alertWindowLayoutBinding.alrDntB.setOnClickListener {
            finish()
        }

调用startActivity(i)时出错

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.abdx79.notifications_manager/com.abdx79.notifications_manager.CAlertWindow}: java.lang.RuntimeException: Unable to invoke no-args constructor for interface java.lang.CharSequence. Registering an InstanceCreator with Gson for this type may fix this problem.

那么我该如何解决这个问题呢？
