//return super.onKeyDown(keyCode, event);

这花了我几个小时，但我终于明白了。我有一个处理标签栏的TabManager.java文件。所以我一直在寻找错误的地方。活动是TabGroupActivity＆gt; ActivityPersonalRewardsGits＆gt; ActivityYourGift
因此，当按下后退按钮时，它触发了TabGroupActivity中的public boolean onKeyDown(int keyCode, KeyEvent event)函数，其中调用了finish();方法（有人在那里偷偷摸摸）。这就是造成这个问题的原因。 This post帮助我解决了这个问题。
