Best Answer-推荐答案

退出 Activity 后，您正试图显示一个对话框。

回答 1 :

You're trying to show a Dialog after you've exited an Activity.

回答 2

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

Call dismiss() on the Dialog instance you created before exiting your Activity, e.g. in onPause() or onDestroy()
