能否请您建议如何解决此问题.代码如下:

Can you please advise how to resolve the issue. Here is the code:

    mSeekBar = findViewById(R.id.seekBar);

    if (mMediaPlayer == null) {
        mMediaPlayer = new MediaPlayer();
    }

    if (mMediaPlayer.isPlaying()) {
        mMediaPlayer.reset();
    }
    mMediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener() {
        @Override
        public boolean onError(MediaPlayer mp, int what, int extra) {
            return false;
        }
    });
    mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            mp.start();
        }
    });

    mMediaPlayer.setOnInfoListener(new MediaPlayer.OnInfoListener() {
        @Override
        public boolean onInfo(MediaPlayer mp, int what, int extra) {
            return false;
        }
    });
    mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        @Override
        public void onCompletion(MediaPlayer mp) {
            mp.reset();
        }
    });

    mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            if (mMediaPlayer != null && fromUser) {

                mMediaPlayer.seekTo(progress * 1000);
                seekBar.setProgress(progress);
            }
        }
    });

    playAudio(url);
}


private void playAudio(String url) {

    mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    try {
        mMediaPlayer.setDataSource(url);
        mMediaPlayer.prepare();
        mSeekBar.setMax(mMediaPlayer.getDuration() / 1000);
        getAudioInfo();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

private void getAudioInfo() {
    PlayMusicActivity.this.runOnUiThread(new Runnable() {

        @Override
        public void run() {
            if (mMediaPlayer != null && mMediaPlayer.isPlaying()) {
                int mCurrentPosition = mMediaPlayer.getCurrentPosition() / 1000;
                mSeekBar.setProgress(mCurrentPosition);
            }
            mHandler.postDelayed(this, 1000);
        }
    });
}

推荐答案

亲爱的朋友们，问题是我试图跳过尚未下载的位置.在首先寻找该位置之前，我正在检查该部分是否已下载.如果没有，我会等到它被下载，然后再寻找那个位置.代码如下:

Dear Friends the problem was that I try to skip position which is not downloaded yet. Before to seek to that position at first I'm checking if that part is downloaded or not. If not I'm waiting until it will be downloaded and after that seeking to that position. Here is the code:

private Handler mHandlerDownloadUpdate = new Handler();
public static MediaPlayer mMediaPlayer;

    if (mMediaPlayer == null) {
        mMediaPlayer = new MediaPlayer();
    } else {
        mMediaPlayer.release();
        mMediaPlayer = new MediaPlayer();
    }

    mMediaPlayer.setOnBufferingUpdateListener(bufferingUpdateListener);
    mSeekBar.setOnSeekBarChangeListener(seekBarChangeListener);

private void initRunnable(final int progress) {
   mRunnable = new Runnable() {
     @Override
     public void run() {
        if (progress * 100 / mDuration < mPercentOfDownload) {
            mMediaPlayer.seekTo(progress * 1000);
            mMediaPlayer.start();
            return;
        }
        mHandlerDownloadUpdate.postDelayed(this, 1000);
    }
};

MediaPlayer.OnBufferingUpdateListener bufferingUpdateListener = new 
MediaPlayer.OnBufferingUpdateListener() {
@Override
public void onBufferingUpdate(MediaPlayer mp, int percent) {
    mPercentOfDownload = percent;
    if (mDuration != 0) {
        int second = percent * mDuration / 100;
        mSeekBar.setSecondaryProgress(second);
    }
}

SeekBar.OnSeekBarChangeListener seekBarChangeListener = new     SeekBar.OnSeekBarChangeListener() {
   public void onProgressChanged(SeekBar seekBar, final int progress, 
   boolean fromUser) {
    if (mMediaPlayer != null && fromUser) {
        if (mMediaPlayer.isPlaying()) {
            mMediaPlayer.pause();
            seekBar.setProgress(progress);
            int a = (progress * 100 / mDuration);
            if (a < mPercentOfDownload) {
                mMediaPlayer.seekTo(progress * 1000);
                mMediaPlayer.start();
            } else {
                mHandlerDownloadUpdate.removeCallbacks(mRunnable);
                initRunnable(progress);
                PlayMusicActivity.this.runOnUiThread(mRunnable);
            }
        } 
    }
}
