I’m trying to fill a spinner city according to the state selected in another spinner via webservice.

But this giving an error in this line in the class usuarioDAO.

Vector<SoapObject> resposta = (Vector<SoapObject>) envelope.getResponse();

Error:

Unchecked cast: java.lang.Object to java.util.vector

My variable list is coming null, I believe it’s because of that mistake.

Check before if the return method is of type Vector, because the compiler is accusing that you are making a direct conversion without checking before the return type.

    if (envelope.getResponse() instanceof Vector) {
        Vector<SoapObject> resposta = (Vector<SoapObject>) envelope.getResponse();
    }

Guys I got.

I switched from Arraylist to only Array ai I managed to populate it with the vector. Thank you all.

Puts the @SuppressWarnings("unchecked")on top of the statement, thus:

@SuppressWarnings("unchecked")
Vector<SoapObject> resposta = (Vector<SoapObject>) envelope.getResponse();

If you don’t, let us know.

hugs.

  • Leonardo, the error is gone, but the Array List is still null. I think it’s because I want to populate an array with a vector. I will post here the full code of the web service, the DOC city and the Activity that populates the ok spinner?
