I have a little problem with a spinner.
I create a Spinner the user click a Button. The Spinner is shown as it should be, but
This looks enough like the turorial, so refer back to that. See below:
I don't see this, but does the main class implement OnItemSelectedListener? Also, You'll want to instantiate the Spinner inside the onCreate() within the main class body.
This line needs to be within the onCreate();
spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());
