Question

我将seekbar与MediaPlayer一起使用。对于seekbar进度，我使用的是AsyncTask，我正在使用setMax并在Miliseconds中进步，以便进度顺利。我在播放seekBar时手动更改video时遇到了一些问题。

搜索栏

max = mediaPlayer.getDuration();
mSeekBar.setMax(max);

这是 SeekBarTask

public class SeekBarTask extends AsyncTask<Void, Void, Void> {

    @Override
    protected Void doInBackground(Void... arg0) {
        while (!isCancelled() && mediaPlayer != null && isPlaying) {
            try {
                Thread.sleep(10);
                publishProgress();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        cancel(true);
        super.onPostExecute(result);
    }

    @Override
    protected void onProgressUpdate(Void... values) {
        super.onProgressUpdate(values);
        if (mediaPlayer != null) {
            if (mSeekBar != null) {
                mSeekBar.setProgress(mediaPlayer.getCurrentPosition());
            }
            if (currentTimeText != null) {
                currentTimeText.setText(convertToTimeFormat(mediaPlayer.getCurrentPosition()));
            }
        }
    }

SeekbarChnageListner

SeekBar.OnSeekBarChangeListener mSeekBarChangeListener = new SeekBar.OnSeekBarChangeListener() {
    @Override
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
        if (fromUser) {
            Debug.d(TAG, "onProgressChanged : Progress = " + progress + " fromUser = " + fromUser);

                if (mediaPlayer != null) {
                    mediaPlayer.seekTo(progress);
                    currentTimeText.setText(convertToTimeFormat(progress));
                }

        }
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {

    }
};

有人可以告诉我哪里弄错了。当我触摸seekBar时，搜索栏会更改为一些非常小的值，我已将其附加到日志中。
