I can not click on the Items in the List View

Good! I am trying to have an activity show in a ListView data of a DB, which I am able to do. But I'm not able to get the app to let me click on the Item of that ListView and open a second activity with new information and more complete.

I attach the code and screenshots!

In the class MisGrupos.java I show in a ListView the groups that contains the BBDD:

What I want is to click on those items and open a second activity (below image) where this data is displayed differently and where you can perform other tasks.

I leave you the code of both classes and the xml of both layout.

I do not know where I have the error in the code but it does not let me click on any of the ListView items, it's as if it were not possible to click on them.

Thank you very much !!!
