To create a ‘connection’ between SeekBar
and MediaPlayer
you need first to get your current recording max duration and set it to your seek bar.
mSeekBar.setMax(mFileDuration/1000); // where mFileDuration is mMediaPlayer.getDuration();
After you initialise your MediaPlayer
and for example press play button, you should create handler and post runnable so you can update your SeekBar
(in the UI thread
itself) with the current position of your MediaPlayer
like this :
private Handler mHandler = new Handler();
//Make sure you update Seekbar on UI thread
MainActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
if(mMediaPlayer != null){
int mCurrentPosition = mMediaPlayer.getCurrentPosition() / 1000;
mSeekBar.setProgress(mCurrentPosition);
}
mHandler.postDelayed(this, 1000);
}
});
and update that value every second.
If you need to update the MediaPlayer
‘s position while user drag your SeekBar
you should add OnSeekBarChangeListener
to your SeekBar
and do it there :
mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(mMediaPlayer != null && fromUser){
mMediaPlayer.seekTo(progress * 1000);
}
}
});
And that should do the trick! : )
EDIT:
One thing which I’ve noticed in your code, don’t do :
public MainActivity() {
mFileName = Environment.getExternalStorageDirectory().getAbsolutePath();
mFileName += "/audiorecordtest.3gp";
}
make all initialisations in your onCreate();
, do not create constructors of your Activity
.
