Android SeekBar to control MediaPlayer progress

Question

I have a SeekBar, it displays correctly MediaPlayer progress. However, I have troubles with seeking - if I seek scroll box somewhere it just return

Answer 1

I am using this simple code to do the trick.

package in.bhartisoftwares.amit.allamitapps;

import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.SeekBar;
import android.widget.Toast;

import java.util.Timer;
import java.util.TimerTask;

public class audioControllerTwo extends AppCompatActivity {
    MediaPlayer mPlayer;        
    SeekBar audioTraverse;

here I have defined My SeekBar and MediaPlayer in public class. Then on OnCreate Method I have code like this:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_audio_controller_two);

    mPlayer = MediaPlayer.create(this, R.raw.song);

Here I am creating mPlayer variable, that finds my audio file called "song" which is present in "raw" folder.

Then I grabbed my SeekBar called "audioTraverse" and assigned it to "audioTraverse" variable and grabbing the "Duration" of audio file and assigning that duration to my "audioTraverse" SeekBar as follows:

    audioTraverse = (SeekBar) findViewById(R.id.audioTraverse);
    audioTraverse.setMax(mPlayer.getDuration());

Now I am running a timer that will run after every second and it will update the SeekBar position accordingly. See the code below:

new Timer().scheduleAtFixedRate(new TimerTask() {
    @Override
    public void run() {
        audioTraverse.setProgress(mPlayer.getCurrentPosition());
    }
},0, 1000); // here 0 represents first time this timer will run... In this case it will run after 0 seconds after activity is launched
// And 1000 represents the time interval afer which  this thread i.e., "run()" will execute. In this case, it will execute after every 1 second

Now I am adding "SeekBarChangeListener", this will look for any changes on SeekBar and in "OnProgressChange()" method I am using ".seekTo()" method to go to a particular duration in audio file. Code is as follows:

        audioTraverse.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            @Override
            public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
                Log.i("Tranverse Change: ", Integer.toString(i));
                mPlayer.seekTo(i);
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
        });
    }
}
