与第三方库的数据绑定

Question

我正在构建一个应用程序，人们可以在其中查看电影列表并观看预告片。我正在使用第三方 youtube 播放器和数据绑定，这是我的 xml 代码

<layout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">


<data>
    <variable
        name="videoID"
        type="String"
        />
</data>
<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".views.TrailerActivity">


    <com.pierfrancescosoffritti.androidyoutubeplayer.core.player.views.YouTubePlayerView
        android:id="@+id/trailer_player"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:videoId="@={videoID}"
        app:autoPlay="true"
        app:showFullScreenButton="false" />

    <Button
        android:id="@+id/play_trailer_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/play"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/trailer_player" />

</androidx.constraintlayout.widget.ConstraintLayout>

这是我的 TrailerActivity

package com.decagon.moviehut.views

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import androidx.databinding.DataBindingUtil
import androidx.lifecycle.ViewModelProvider

import com.pierfrancescosoffritti.androidyoutubeplayer.core.player.views.YouTubePlayerView
import kotlinx.android.synthetic.main.activity_trailer.*
    import kotlin.properties.Delegates

class TrailerActivity : AppCompatActivity() {

    private lateinit var playerView: YouTubePlayerView
    private lateinit var viewModel: TrailerViewModel
    private lateinit var player: YouTubePlayer

    private lateinit var binding: ActivityTrailerBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = DataBindingUtil.setContentView(this, R.layout.activity_trailer)

        playerView = findViewById<YouTubePlayerView>(R.id.trailer_player)
        viewModel = TrailerViewModel(this.application)
        val id = intent.getIntExtra("movie_id", 0)
        val videoID = viewModel.getKey(id)

        lifecycle.addObserver(playerView);

        binding.videoID = videoID

        playerView.addYouTubePlayerListener(object: AbstractYouTubePlayerListener(){
            override fun onReady(youTubePlayer: com.pierfrancescosoffritti.androidyoutubeplayer.core.player.YouTubePlayer) {
               // youTubePlayer.loadVideo(videoID, 0f)
            }
        })

    }
}

当我尝试构建时，出现以下构建错误

我怀疑问题可能来自数据绑定和 youtube 播放器之间的交互
