No idea how being on service class to get float from seekbar on layoutt. Android Studio

Question

My aim is to manage volume by seekbar of background music. I created background music by service. I have media player in Service class:

public class ModernService extends Service  {

private MediaPlayer modernsong;
private SeekBar volumeSeekBar;
AudioManager am;


@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

public ModernService() {
    super();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
     am = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    modernsong =MediaPlayer.create(this,R.raw.modern);
    modernsong.setLooping(true);
    modernsong.start();
    return START_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();

    modernsong.stop();
}

}

The question is how can i get float from a seekbar that is on layout. Thanks in advance

Answer 1

1. First initialize the volumeSeekbar and set the max value.

   volumeSeekBar = findViewById(R.id.seekBarId); volumeSeekBar.setMax(100);

2. Then you need to add OnSeekBarChangeListener to the veiw.

   volumeSeekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

           @Override
           public void onStopTrackingTouch(SeekBar seekBar) {
   
           }
   
           @Override
           public void onStartTrackingTouch(SeekBar seekBar) {
   
           }
   
           @Override
           public void onProgressChanged(SeekBar seekBar, int progress,
                   boolean fromUser) {
             //any ui changes you wanted to do on user action on seekbar
           }
       });
   

3. Now you can get the value from the seekbar as volumeSeekBar.getProgress();

4. In service class onStartCommand is having direct access to intent. So while starting the service through intent you can pass the seekbar value.

   Intent mIntent = new Intent(this, Service.class); Bundle extras = mIntent.getExtras(); extras.putString(key, seekbarValue);
