问题
I have some dependencies between my spinners and it happens, that a spinner becomes empty.
The problem now is, that I don't know how to clear the spinner, I'm adopting the data of the adapter, notify the adapter and if I click the spinner, there are no values in there, but the spinner's selected item is NOT cleared and still is displayed...

I'm not sure what you want, but to delete all itens in your spinner you can set the adapter null, like this:
mySpinner.setAdapter(null);
and if you want to remove a specific item, then you should remove it from your adapter and set your spinner again
mySpinner.setAdapter(myAdapter);
