不要用MediaPlayer.create(mContext,Uri.parse(url));来做，这个用起来有点问题，不过有些手机没事。使用以下方式

    private void playVoice(String voicePath){
//        MediaPlayer player = MediaPlayer.create(context, Uri.parse(voicePath));
        MediaPlayer player = new MediaPlayer();
        try {
            player.setDataSource(voicePath);
        }catch (IOException e){
            e.printStackTrace();
        }
        player.prepareAsync();
        player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mediaPlayer) {
                mediaPlayer.start();
            }
        });
    }
