Как получить значение spinner для отправки формы

Question

Я сделал этот код, чтобы я мог отправлять информацию на мой сайт. Только сейчас я хочу загрузить категорию из spinner, которую я пробовал:

String mCategory = category.getItemAtPosition (что добавить сюда?). ToString();

Я просто не знаю, как это сделать, я надеюсь, что кто-то это сделает.

Там куча getSelected*()methods for the spinner. Вероятно, вы хотите getSelectedItem().
