Expoplayer 显示黑屏并且不在回收站视图中播放视频

Question

我正在使用 Expoplayer 将视频显示为 recyclerview 中的第一个项目，我现在从 mp4 扩展中的 url 获取视频，它应该在屏幕显示时自动播放我还将整个布局包装在框架布局，因为有时我想在运行应用程序时隐藏视图，它显示黑屏，我不知道为什么！

这是我应该在哪里播放视频的viewholder 有人可以帮我吗？

class SpotlightViewHolder(val itemVw: View, val adapter: NewNewsAdapter) : RecyclerView.ViewHolder(itemVw), Player.EventListener {
lateinit var simpleExoplayer: SimpleExoPlayer
private var playbackPosition: Long = 0
private val dataSourceFactory: DataSource.Factory by lazy {
    DefaultDataSourceFactory(adapter.activity, "exoplayer-sample")
}

fun bind(spotLightData: List<SpotlightModel>?) {

    if (spotLightData == null) {
        itemVw.spotLayoutRoot.toggleVisibility(false)
    } else {
        val spotlight = spotLightData[0]

        itemVw.spotLayoutRoot.toggleVisibility(true)


        when (spotlight.adType) {
            "image" -> {
                itemVw.spot_light_image.toggleVisibility(true)
                itemVw.video_view.toggleVisibility(false)
                GlideApp.with(adapter.activity).load(spotLightData[0].coverUrl).into(itemVw.spot_light_image)
            }
            "video" -> {
                itemVw.spot_light_image.toggleVisibility(false)
                itemVw.video_view.toggleVisibility(true)
                initializePlayer(spotlight.coverUrl)

            }
        }
        itemVw.btn_spotLight_cta.text = spotlight.cta.title
        itemVw.btn_spotLight_cta.setOnClickListener {
            adapter.callback.spotLightClicked(spotLightData[0])
        }
    }
}

private fun initializePlayer(url: String) {
    Log.e(TAG, "initializePlayer: --------------------------------,-")
    var simpleExoplayer = SimpleExoPlayer.Builder(adapter.activity).build()
    preparePlayer(url)
    itemVw.video_view.player = simpleExoplayer
    simpleExoplayer.seekTo(playbackPosition)
    simpleExoplayer.playWhenReady = true
    simpleExoplayer.addListener(this)
}


private fun preparePlayer(videoUrl: String) {
    val uri = Uri.parse(videoUrl)
    val mediaSource = buildMediaSource(uri)
    simpleExoplayer.prepare(mediaSource)
}

override fun onPlayerError(error: ExoPlaybackException) {
    // handle error
    Log.e(TAG, "onPlayerError: -----------------------------${error}")
}


private fun buildMediaSource(uri: Uri): MediaSource {
    return ProgressiveMediaSource.Factory(dataSourceFactory)
            .createMediaSource(uri)
}


private fun releasePlayer() {
    playbackPosition = simpleExoplayer.currentPosition
    simpleExoplayer.release()
}}

这是布局

只需使用您的 SimplePlayerView 实例添加这一行

playerView.setKeepContentOnPlayerReset(true);

或者，您也可以通过您的 layout.xml 文件执行此操作，

app:keep_content_on_player_reset="true"
