exoplayer 发布后音频继续播放

Question

我在对话中使用 Exoplayer。我希望视频在对话框打开时自动播放。什么时候 simpleExoPlayer.prepare() 片段处于活动状态我可以自动播放但是当我关闭对话框时音频会继续播放。在激活 simpleExoPlayer.prepare() 之前，当我关闭对话框时音频停止。是否有其他方法可以自动播放 exoplayer 或在对话框关闭时停止音频？

class VideoViewDialog (context: Context) : BaseDialog<LayoutDialogVideoViewBinding>(context) {


private var videoUrl : String = ""
private lateinit var simpleExoPlayer: ExoPlayer

override fun populateUi() {
    setCanceledOnTouchOutside(true)
    mBinding?.apply {

        initializePlayer()
    }
}


private fun initializePlayer() {
    val mediaDataSourceFactory: DataSource.Factory = DefaultDataSource.Factory(context)

    val mediaSource = ProgressiveMediaSource.Factory(mediaDataSourceFactory).createMediaSource(
        MediaItem.fromUri(videoUrl))

    val mediaSourceFactory: MediaSource.Factory = DefaultMediaSourceFactory(mediaDataSourceFactory)

    simpleExoPlayer = ExoPlayer.Builder(context)
        .setMediaSourceFactory(mediaSourceFactory)
        .build()

    simpleExoPlayer.addMediaSource(mediaSource)

    simpleExoPlayer.playWhenReady = true
    simpleExoPlayer.prepare()

    mBinding?.apply {

        playerView.player = simpleExoPlayer
        playerView.requestFocus()


    }
    simpleExoPlayer.play()

}

private fun releasePlayer() {
    simpleExoPlayer.release()
}

public override fun onStart() {
    super.onStart()

    if (Util.SDK_INT > 23) initializePlayer()
}

public override fun onStop() {
    super.onStop()

    if (Util.SDK_INT > 23) releasePlayer()
}

override fun getLayoutRes(): Int {
    return R.layout.layout_dialog_video_view
}


companion object{
    fun newInstance(
        context: Context,
        videoUrl : String,
    ) : VideoViewDialog{
        val dialog = VideoViewDialog(context)
        dialog.also {
            it.videoUrl = videoUrl
        }
        return dialog
    }
}
}

我在 .release() 之前尝试了 .stop、clearVideoSurface()、playerView.player = null。没用

你似乎打了两次 initializePlayer()。导致播放两个 Exoplayer 实例；您只能释放 simpleExoPlayer 变量引用的那一个。
