How can I make a seekbar be updated with the progress of a song for Xamarin Android

Question

I'm creating a simple app that plays music in Xamarin Android. I can't get the seekbar to update itself with the song's progress. In JAVA the Runnable interface is used.

Here is my code snippet

`protected override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);
            SetContentView(Resource.Layout.MediaPlayer);

            player = Android.Media.MediaPlayer.Create(this, Resource.Raw.test);

            playButton = FindViewById<Button>(Resource.Id.play);
            pauseButton = FindViewById<Button>(Resource.Id.pause);
            stopButton = FindViewById<Button>(Resource.Id.stop);

                playButton.Click += OnPlayClick;
                pauseButton.Click += OnPauseClick;
                stopButton.Click += OnStopClick;

            seekBar = FindViewById<SeekBar>(Resource.Id.seekBar);
        }

        private void OnPlayClick(object sender, EventArgs e)
        {

            player.Start();
        }

        private void OnPauseClick(object sender, EventArgs e)
        {
            player.Pause();
        }

        private void OnStopClick(object sender, EventArgs e)
        {
            player.Stop();
            player.Prepare();
            player.SeekTo(0);
        }`

This is the basic player implementation.

This is the java version of what I want to do. How to use a Seekbar in android as a seekBar as well as a progressBar simultaneously?

Answer 1

You need to add a timer when you start your player.

Try the following code:

    public class MainActivity : Activity
    {
        Button playButton;
        Button pauseButton;
        Button stopButton;
        SeekBar seekBar;
        Android.Media.MediaPlayer player;
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);

            player = Android.Media.MediaPlayer.Create(this, Resource.Raw.hello);

            playButton = FindViewById<Button>(Resource.Id.play);
            pauseButton = FindViewById<Button>(Resource.Id.pause);
            stopButton = FindViewById<Button>(Resource.Id.stop);

            playButton.Click += OnPlayClick;
            pauseButton.Click += OnPauseClick;
            stopButton.Click += OnStopClick;



            seekBar = FindViewById<SeekBar>(Resource.Id.myseekBar);
        }



        private void OnPlayClick(object sender, System.EventArgs e)
        {

            player.Start();
            seekBar.Max = player.Duration;
            System.Timers.Timer timer = new System.Timers.Timer();
            timer.Interval = 10;
            timer.Elapsed += OnTimedEvent;
            timer.Enabled = true;
        }

        private void OnTimedEvent(object sender, System.Timers.ElapsedEventArgs e)
        {
            seekBar.Progress = player.CurrentPosition;
        }

        private void OnPauseClick(object sender, System.EventArgs e)
        {
            player.Pause();
        }

        private void OnStopClick(object sender, System.EventArgs e)
        {
            player.Stop();
            player.Prepare();
            player.SeekTo(0);
        }
    }
}

When you click playButton the timer event will be called and update the seekbar UI timely.
