I know how to control sound volume with a seekbar:

audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
    int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
    int curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
    SeekBar volControl = (SeekBar)findViewById(R.id.volbar);
    volControl.setMax(maxVolume);
    volControl.setProgress(curVolume);
    volControl.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        @Override
        public void onStopTrackingTouch(SeekBar arg0) {
        }

        @Override
        public void onStartTrackingTouch(SeekBar arg0) {
        }

        @Override
        public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
            audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, arg1, 0);
        }
    });

but.. I don't know how to do it in a AsyncTask class which show a dialog(with seekbar) while sound is playing... any ideas or examples?

thanks!

You don't have access to the UI thread inside of the doInBackground() method of AsyncTask. – Ryan Gray Jul 11 '12 at 11:43
so.. is it imposible to do? My AsyncTask in preExecute method display a loading.. in doInBackground method start the sound and in postExecute display a dialog in which I want my seekbar volume control.. – user1364684 Jul 11 '12 at 12:01
why you would do this :\ – Mohammad Ersan Jul 11 '12 at 14:26
