Question

在m中使用android搜索栏与播放和剩余时间为使用线程的songprgress处理程序的以下示例代码。每当我点击下一首/上一首歌时，它都会显示大整数值。如何解决这个问题？

class SongProgressUpdateThread extends Thread {
    public void run() {

        if (mp != null) {
            int currentPosition = 0;
            int total = mp.getDuration();
            while (currentPosition < total && mp.isPlaying() && stopSongProgressThread==false ) {
                try {
                    Thread.sleep(500);
                    currentPosition = mp.getCurrentPosition();
                } catch (InterruptedException e) {
                    return;
                } catch (Exception e) {
                    return;
                }
                songProgress.setProgress(currentPosition);
                showProgress(currentPosition, total);
            }

        }
    }
}





private void showProgress(int currentPosition, int duration) {
    Bundle bundle = new Bundle();
    bundle.putString("playedTime", getPlayedTime(currentPosition));
    bundle.putString("remainingTime",getRemainigTime(currentPosition, duration));
    Message msg = new Message();
    msg.setData(bundle);
    songProgresshandler.sendMessage(msg);
}

Handler songProgresshandler = new Handler() {
    public void handleMessage(Message message) {
        final Bundle b = message.getData();
        playedTime.setText(b.getString("playedTime"));
        remainingTime.setText("-" + b.getString("remainingTime"));
    }
};

也许您可以尝试使用VideoView和MediaController来完成它。如：

VideoView vv = (VideoView)this.findViewById(R.id.videoview);
Uri uri = Uri.parse(path);
MediaController mediaController = new MediaController(this);
mediaController.setMediaPlayer(vv);
vv.setVideoURI(uri);
vv.setMediaController(mediaController);
vv.start();
mediaController.show();

单击“下一个/上一个”按钮时您做了什么也许mediaPlayer处于无效状态，看LogCat里面的任何错误信息？（比如“无效的stauts中的”getDuration（）“）

seekbar播放时间和剩余时间显示大整数值。
