Kotlin 找不到 TextView(布局)

Question

我有一个问题，Kotlin找不到我的TextView或Layout，然后崩溃与错误

"Invalid ID 0x00000000 android.content.res.Resources$NotFoundException: Resource ID #0x0"

我真的不知道为什么。下面是来自

的代码

import android.content.Context
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.ArrayAdapter
import android.widget.TextView
class TicketsArrayAdapter(context: Context?, tickets: List<Ticket?>?) :
ArrayAdapter<Ticket?>(context!!, 0, tickets!!) {
@Suppress("NAME_SHADOWING")
class TicketsArrayAdapter(context: Context?, tickets: List<Ticket?>?) :
ArrayAdapter<Ticket?>(context!!, 0, tickets!!) {
override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
var convertView = convertView
val ticket = getItem(position)
if (convertView == null) {
convertView =
LayoutInflater.from(context).inflate(R.layout.popup_window, parent, false)
}
val titleView = convertView!!.findViewById<TextView>(R.id.title_view)
titleView.text = ticket!!.title
return convertView
}
}
}

这是我的布局，命名为popup_window

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/title_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp" />
<TextView
android:id="@+id/description_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp" />
</LinearLayout>

你们有人知道为什么会崩溃吗?如果你需要更多的代码，就说出来。整个Log-cat在这里

我试着填上"空白"。也就是r.b layout和r.d new，并检查是否一切都写对了。我还重新制作了popup_windows.xml文件

问题是我使用了两次类TicketsArrayAdapter，因此应用程序崩溃了。感谢所有试图帮助我的人。
