Android: problems with getSelectedItem on a spinner

Question

I have a Spinner, and put the selected item in the body of a mail. this is my code:

@Override
protected void onCreate(Bundle savedInstanceState) {
         


        

Answer 1

Move the line

final String taglia = spinnerTaglia.getSelectedItem().toString();

to inside your OnClickListener

Currently, you're trying to read the selected item before anything has been selected. You should also ensure that getSelectedItem() isn't returning null because, unless you enable / disable the btnCompilaOrdine button (when an item is selected), the user can press the button without selecting an item in the spinner.
