How To Get Seekbar To Automatically Move On Song Play?

I have looked everywhere to fix my problem but i just cant seem to get it going. How do i make seekbar automatically slide with song play ? this is what i have so far. ArrayList<

Solution 1:

First of all you should define a Runnable object that will be triggered each second. For your situation, in everysecond that class will be triggered.

I will paste some example code. Here is the runnable class.

Runnable timerRunnable = new Runnable() {

   publicvoidrun() {
    // Get mediaplayer time and set the value                           // This will trigger itself every one second.
    updateHandler.postDelayed(this, 1000);
   }
};

And you should also have a Handler that will trigger Runnable instance.

HandlerupdateHandler=newHandler();

updateHandler.postDelayed(timerRunnable, 1000);

I hope that sample will help you.

Solution 2:

I am using a Runnable and it looks like this:

private Runnable mUpdateTimeTask = new Runnable()
                                   {
                                     publicvoidrun()
                                       {
                                         long currentDuration = mediaPlayer.getCurrentPosition();
                                         long elapsedDuration = mediaPlayer.getDuration() - currentDuration;

                                         // Displaying current song progress// playing
                                         tvProgressLeft.setText("" + utils.milliSecondsToTimer(currentDuration));
                                         // Displaying remaining time
                                         tvProgressRight.setText("" + utils.milliSecondsToTimer(elapsedDuration));

                                         // Updating progress barint progress = (int) (utils.getProgressPercentage(currentDuration,
                                             elapsedDuration));
                                         // Log.d("Progress", ""+progress);
                                         songProgressBar.setProgress(progress);

                                         // Running this thread after 100// milliseconds
                                         handler.postDelayed(this, 100);
                                       }
                                   };

But better yet here is a link to the sample that I have adopted.

http://www.androidhive.info/2012/03/android-building-audio-player-tutorial/

Regarding the tutorial the only thing that will not work is retrieving and filtering the song from the given file path. Somehow I couldn't get it to work. But I found another solution which was to write your own FileFilter and use it instead of the default File Filter.
