MediaPlayer onCompletion重置速度参数

问题描述

由于某种原因，当调用onCompletionListener时，我的速度参数设置为0，但是可以检索到音高。

如何在onCompletion中获取速度参数？

OnCompletion侦听器

@Override
    public void onCompletion(MediaPlayer mp) {
        Log.d(TAG,"OnCompletion called!");
            if (isRepeat) {
                    if(!songList.isEmpty()) {
                    activeSong = songList.get(songIndex);
                    mp.reset();
                    try {
                        mp.setDataSource(this,activeSong.getData());
                        mp.prepare();
                        mp.start();
                    } catch (Exception e) {
                        Log.e(TAG,"ERROR SETTING DATA SOURCE",e);
                        Toast.makeText(this,"Can't play song! Possible cause: Unsupported file format",Toast.LENGTH_SHORT).show();
                       }
                    }
                } else if (isShuffle) {
                Random random = new Random();
                songIndex = random.nextInt((songList.size() - 1) + 1);

                playSong();

            } else if (songIndex < songList.size() - 1) {
                PlaybackParams params = mp.getPlaybackParams();
                Log.d(TAG,"onCompletion params: pitch= "+ params.getPitch() + " speed= " +params.getSpeed());
                nextSong();
            } else {
                songIndex = 0;
                playSong();
            }
    }

Logcat输出

 params: pitch= 1.2829928 speed= 1.2333759

 onCompletion params: pitch= 1.2829928 speed= 0.0
