Android服务:搜索栏不工作

Question

我正在使用一个管理搜索栏的Android服务。下面是代码(我只是放了关于搜索栏的代码):

    public class MediaPlayerService extends Service implements
        Runnable,
        SeekBar.OnSeekBarChangeListener {
    private MediaPlayer mediaPlayer = null;
    private AudioManager audioManager;
    private SeekBar seekBarTime;
    @Override
    public void onCreate() {
        //SET SEEKBAR
        LayoutInflater inflater = ( LayoutInflater ) getSystemService( LAYOUT_INFLATER_SERVICE );
        View layout = inflater.inflate( R.layout.play_song , null);
        seekBarTime = (SeekBar) layout.findViewById(R.id.seekBarTime);
        seekBarTime.setOnSeekBarChangeListener(this);
        Thread thread = new Thread(this);
        thread.start();
    }
    public void run() {
        if(mediaPlayer != null) {
            int currentPosition = 0;
            int total = mediaPlayer.getDuration();
            seekBarTime.setMax(total);
            while (currentPosition < total && mediaPlayer != null ) {
                try {
                    Thread.sleep(1000);
                    currentPosition = mediaPlayer.getCurrentPosition();
                } catch (InterruptedException e) {
                    return;
                } catch (Exception e) {
                    return;
                }
                seekBarTime.setProgress(currentPosition);
            }
        }
    }
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
        Log.w("disgustingapps", "seekbar");
        if (fromUser == true) {
            mediaPlayer.seekTo(progress);
        }
    }
    public void onStartTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub
    }
    public void onStopTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub
    }
}

问题有两个。我试着用我蹩脚的英语来解释:1)我希望搜索栏自动更新的服务，以显示歌曲的当前时间(mediaPlayer.getCurrentPosition())2)我希望允许用户移动搜索栏，以便在歌曲的时间之间移动这两件事都行不通。看起来搜索栏是完全"独立"于代码的。我的意思是:光标根本不会移动，而且如果用户移动它，歌曲也不会做任何事情而继续播放。请帮帮我提前谢谢大家

你不能在Android Service中使用搜索栏(或任何UI控件)
