嗨，我为我的一个名为 Aussie Bloke 的角色制作了一个音板——音板包含 30 个按钮和 30 个媒体播放器。我最初对所有按钮都使用了一个媒体播放器，但最终在大约 20 次随机按下后声音会停止播放。所以我决定为我使用的原始音板模板中使用的每个声音使用单独的媒体播放器对象。这工作得很好，你可以整天按下按钮并让声音正常工作..但我遇到的问题是，当活动被发送到后台并在几秒钟后再次恢复时，当你按下按钮时应用程序崩溃..我尝试创建一个 onResume 方法来准备所有玩家，但这只是让应用程序从一开始就崩溃..

您需要onResume()在您的活动中实现方法并在那里重新创建您的媒体播放器对象：

public void onResume()  {
  super.onResume();

 // ...

 beer1 = MediaPlayer.create(this, R.raw.beer1);
 beer2 = MediaPlayer.create(this, R.raw.beer2);
 beer3 = MediaPlayer.create(this, R.raw.beer3);

 // ...
}

您可以在此处阅读有关活动生命周期的更多信息：http: //developer.android.com/training/basics/activity-lifecycle/index.html
