为什么android mediaPlayer“onBufferingUpdate”不能正常工作

Question

 mPlayer.setOnPreparedListener(new OnPreparedListener() {
  @Override
  public void onPrepared(MediaPlayer mp) {
    hideBgAndLoadProcess();
    if (mPlayer.isPlaying()) {
      mPlayer.stop();
    }
    Log.e("TAG", "onPrepared is called");
    mPlayer.start();
  }
});
mPlayer.setOnBufferingUpdateListener(new OnBufferingUpdateListener() {
  @Override
  public void onBufferingUpdate(MediaPlayer mp, int percent) {
    Log.e("TAG", "percent is :" + percent);
    sbProgress.setSecondaryProgress(percent);
    int currentProgress =
        sbProgress.getMax() * mPlayer.getCurrentPosition() / mPlayer.getDuration();
    Log.e(currentProgress + "% play", percent + "% buffer");
  }
});

myPlayer 设置了“onBufferingUpdateListener”但效果不佳，有人知道为什么吗？当 myPlayer 播放时，“onBufferingUpdate”似乎从未被调用，因为日志没有被打印出来。

尝试在启动媒体之前添加监听器。
