java - mp3/aac 播放超过 1 分钟时无法显示特定毫秒的文本

Question

我创建像卡拉OK这样的应用程序。但是，当我的应用播放 mp3/aac 超过 1 分钟时。我创建的这些文本不显示。然而 setText(); 1分钟以下正常显示。我该如何解决。我明天必须派老师来。代码很简单。非常感谢。

            mHandler.sendEmptyMessageDelayed(0, 1);
        }
    };
    mHandler.sendEmptyMessage(0);

    mMediaPlayer.setOnPreparedListener(new OnPreparedListener() {
        public void onPrepared(MediaPlayer mp) {
            mHandler.post(new Runnable() {
                public void run() {
                    mMediaController.show(0);
                    // mMediaPlayer.reset();
                    mMediaPlayer.start();
                }
            });
        }
    });

    mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {

        @Override
        public void onCompletion(MediaPlayer mp) {
            // TODO Auto-generated method stub
            Intent newAc = new Intent(Okkaraoke.this, Show.class);
            startActivity(newAc);
        }
    });
}

我有音乐 03.45 分钟。在handleMassege() 中。我尝试最终 int/long sPos = mMediaPlayer.getCurrentPosition(); 也。但是，这行不通。setText 与上面的代码相同。非常感谢。
