答案 1:
您试图在退出 Activity 后显示一个对话框.
You're trying to show a Dialog after you've exited an Activity.
答案 2
在某些情况下，此错误可能会产生一些误导(尽管答案仍然完全准确) - 即在我的情况下在 AsyncTask 中引发了未处理的异常，导致活动关闭，然后打开的进度对话框导致此异常..所以真正的"异常在日志中稍早
This error can be a little misleading in some circumstances (although the answer is still completely accurate) - i.e. in my case an unhandled Exception was thrown in an AsyncTask, which caused the Activity to shutdown, then an open progressdialog caused this Exception.. so the 'real' exception was a little earlier in the log
答案 3
在退出之前在您创建的 Dialog 实例上调用 dismiss()活动，例如在 onPause() 或 onDestroy() 中
Call dismiss() on the Dialog instance you created before exiting your Activity, e.g. in onPause() or onDestroy()
