我非常感谢您的帮助。

引用this answer：“您在退出活动后尝试显示对话框。”它归结为活动结束后（通过调用finish()或使用后退按钮（这里是这种情况））的问题，您尝试在活动的顶部显示一个对话框，而不是已经存在了。这是不可能的。

似乎在Activity正在改变时启动了Dialog。即当要显示Dialog时，不存在正确活动的窗口。对话框与启动它的活动窗口相关联。
答案 2 :(得分：1)
我要看的是：
12-04 22:10:56.659: E/WindowManager(837): at kids.iq.kidsiqpicturesquestion.animal_q_hard_4.onBackPressed(animal_q_hard_4.java:5462)
很可能函数中的某些东西导致错误。尝试评论整个功能，看看你是否还有它。

这将显示异常..

这是因为您在Activity中显示了一个对话框..但此处Activity已经完成，因此它会给您例外的信息..
