Android: How to override setAdapter() in AutoCompleteTextView?

Question

How do you override the void setAdapter(T adapter) method for AutoCompleteTextView?

class CustomAutoCompleteTextView extends AutoCompleteTextView {

    //constructors

    @Override
    public void setAdapter(??? adapter) {
        super.setAdapter(adapter);
    }
}

I referenced the android dev page for the method signature, but was confused at the generic T. Earlier in the page, it says "T extends ListAdapter & Filterable". I'm not sure how to translate this into the Override signature. I also checked some previous stackoverflow questions (one about a ListView adapter), but it didn't help.

A solution would be nice, but also an explanation on what is going on would also be appreciated.

Thanks!

Answer 1

I think I just figured it out. Go figure, right when you go for help. Here is my answer:

@Override
public <T extends ListAdapter & Filterable> void setAdapter(T adapter) {
    super.setAdapter(adapter);
}

Turns out you need to specify that class T (I was getting 'unresolved class T' before).
