【问题描述】：

在我的应用程序中，我使用BottomNavigationViewEx 库在片段之间切换，在其中一个片段中，我使用 YoutubePlayerSupportFragment 来显示 youtube 播放器。但是，似乎不可能对事务进行分段，因为 YoutubePlayerSupportFragment 似乎不兼容。

类型不匹配。

必需：片段

找到：MidiaFragment

MainActivity 中的底部导航：

viewEx.onNavigationItemSelectedListener = BottomNavigationView.OnNavigationItemSelectedListener { item ->
        val fragmentManager = supportFragmentManager
        val fragmentTransaction = fragmentManager.beginTransaction()

        when (item.itemId) {
            R.id.bnv_home -> {
                fragmentTransaction.replace(R.id.viewPager, FeedFragmentBeta()).commit()
                return@OnNavigationItemSelectedListener true
            }
            R.id.ic_destaques -> {
                fragmentTransaction.replace(R.id.viewPager, DestaquesFragment()).commit()
                return@OnNavigationItemSelectedListener true
            }
            R.id.ic_camera -> {
                fragmentTransaction.replace(R.id.viewPager, ChatDeMidiaFragment()).commit()
                return@OnNavigationItemSelectedListener true
            }
            R.id.ic_chat -> {
                fragmentTransaction.replace(R.id.viewPager, ChatFragment()).commit()
                return@OnNavigationItemSelectedListener true
            }
            R.id.bnv_perfil -> {
                fragmentTransaction.replace(R.id.viewPager, PerfilFragment()).commit()
                return@OnNavigationItemSelectedListener true
            }
        }
        false
    }

片段：

class MidiaFragment : YouTubePlayerSupportFragment(), YouTubePlayer.OnInitializedListener {

private val GOOGLE_API_KEY = "ABC..."
lateinit var youtubePlayerView: YouTubePlayerView

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                          savedInstanceState: Bundle?): View {

    // Inflate the layout for this fragment
    val view = inflater.inflate(R.layout.fragment_midia, container, false)

    youtubePlayerView = view.findViewById(R.id.youtubePlayerView)
    youtubePlayerView.initialize(GOOGLE_API_KEY,this)


    return view

}

override fun onInitializationSuccess(provider: YouTubePlayer.Provider, youTubePlayer: YouTubePlayer, wasRestored: Boolean) {

    // l2UDgpLz20M
    // 1-AozVirb88
    // PLOcMSsuppV4q38HhyXXRPxFpwbX_04jf3

    //youTubePlayer.cueVideo("l2UDgpLz20M")
    youTubePlayer.loadVideo("l2UDgpLz20M")

}

override fun onInitializationFailure(provider: YouTubePlayer.Provider, youTubeInitializationResult: YouTubeInitializationResult) {

}

布局：

    <?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorBackgroundNightBlue"
    tools:context=".Fragment.MidiaFragment">

    <com.google.android.youtube.player.YouTubePlayerView
        android:id="@+id/youtubePlayerView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"/>

</FrameLayout>

打开片段会使应用程序崩溃。如何解决此错误？
