问题
Looking to create a menu toggle that switches between two possible arrays for a spinner. For example, if the spinner is set to show array A, then when I press this menu button, I want the spinner to be set to array B. If I press it again, I want it to be set back to array A.
I can handle the if/then statements and all, but how do I call the spinner's array adapter? I know how to call its value using getSelectedItemPosition(); but is there a similar method for retrieving WHICH array it is currently set to?
回答1:
I think AdapterView#getAdapter() is inherited by android.widget.Spinner?
回答2:
What you're seeing is that AdapterView#getAdapter() is an abstract method. You want to be using AbsSpinner#getAdapter() which is where getAdapter() is actually implemented. This will return a SpinnerAdapter.
