我正在使用管理搜索栏的 Android 服务。这是代码(我只是放了有关搜索栏的代码):

    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。我将尝试用我糟糕的英语来解释这一点:1)我希望服务自动更新搜索栏以显示歌曲的当前时间( mediaPlayer.getCurrentPosition() )2)我希望用户被允许移动搜索栏以便在歌曲的时间之间移动 这两件事都不起作用。似乎 seekbar 与代码完全“独立”。我的意思是:光标根本不移动,如果用户移动它,歌曲会继续播放,什么也不做。请帮助我提前谢谢你

您不能在 Android 服务中使用 SeekBar(或任何 UI 控件)
