Activity ListarAlumnos:

There are many question which handle the similar problem. There seems to be a problem with context. See:

Dialog Box in Activity group inside a TabActivity not working

Problems on an activitygroup under tabshost

Hope this helps.

I think each activity should have a dialog box with their own context. This error errors when you are trying to open Dialog box when other the activity on which it should run is already ended. It might also occour when the Dialobox is showing and the activity from which it was opened gets destroyed. – Shobhit Puri May 26 '13 at 02:17
you're right! but the getParent () but not work for me and the truth and tried everything thanks for your answers! – Rosa María Torres Guerra May 26 '13 at 03:24
I also noticed that in the code above that you've only created the DialogBox. Where are you `dismissing` it? There should a place where you destroy/close it by using `.dismiss()`. It can be either on clicking any buttons in Dialog or any other way. But if you don't close it, it will surely give this error. – Shobhit Puri May 26 '13 at 03:36
Antes de usar tab corrió perfectamente, el problema surgio cuando le añadí el tab al principio y por consiguiente los ActivityGroup :( – Rosa María Torres Guerra May 26 '13 at 03:58
Before using tab ran perfectly, the problem arose when I added the tab at the beginning and therefore the ActivityGroup :( – Rosa María Torres Guerra May 26 '13 at 03:59
you still have the problem? – Shobhit Puri May 29 '13 at 06:10
