How to implement ExoPlayer with Databinding?

问题

I have a class activity_player layout in which I have exoplayer2.ui.PlayerView and I created exo_player_control_view so that it overrides default controls in ExoPlayer. So I wanted to use Databinding in newly created custom control view but don't know how to do it. Any advice?

It is actually an open issue over here, but yet to be solved. So is there anyone who had a workaround to make exo_player_control_view Databinding friendly?

回答1:

You can use binding variable inside fragment/activity to access the playerView inside fragment/activity and

  val uri: Uri? = if (url is String) Uri.parse(url as String?) else url as Uri?
    val trackSelector =
        DefaultTrackSelector(AdaptiveTrackSelection.Factory(DefaultBandwidthMeter()))
    val player: SimpleExoPlayer = ExoPlayerFactory.newSimpleInstance(view.context, trackSelector)
    val dataSourceFactory = DefaultDataSourceFactory(view.context, "ua")
    val mediaSource =
        ExtractorMediaSource(uri, dataSourceFactory, DefaultExtractorsFactory(), null, null)
    player.prepare(mediaSource)
    player.apply {
        volume = 0f
        repeatMode = Player.REPEAT_MODE_ONE
        playWhenReady = true
        videoScalingMode = C.VIDEO_SCALING_MODE_SCALE_TO_FIT
    }
    binding.playerView.setResizeMode(AspectRatioFrameLayout.RESIZE_MODE_FILL)
    binding.playerView.player = player
