kotlin - 在对话框中检索 View

Question

我正在尝试在对话框中操作 View ，但我可以检索 View 的唯一方法是使用 Java 老式方式，如下所示:

 class MyDialog: DialogFragment() {
        override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
            val alert = AlertDialog.Builder(context!!)
            val inflater = LayoutInflater.from(activity)
            val view = inflater?.inflate(R.layout.pg_dialog, null)
            with(alert) {
                setView(view)
                setNeutralButton(R.string.scambio_back, DialogInterface.OnClickListener({ _: DialogInterface, _: Int -> dialog.dismiss() }))
            }
            view?.findViewById<TextView>(R.id.dialog_name)?.text = person.name
            view?.findViewById<TextView>(R.id.dialog_surname)?.text = person.surname

            return alert.create()
        }
    }

你知道有什么方法可以在 Kotlin 中检索内部 View ，避免 findViewById 吗？

[编辑] 这是 build.gradle 文件:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 27
defaultConfig {
    applicationId "com.project.persons"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:27.0.2'
    implementation 'com.android.support:recyclerview-v7:27.0.2'

    implementation 'com.firebaseui:firebase-ui-auth:3.2.2'

}

在这种情况下，当您不在 Fragment 中时或 Activity ，但有 View如果您想搜索具有给定 ID 的子项，则可以使用 Kotlin Android Extensions 和以下语法:

view.dialog_name.text = person.name
view.dialog_surname.text = person.surname

与使用扩展程序时一样，请确保您拥有正确的导入。
