I'm getting the error code I've printed below. I'm trying to use fragments and on my first fragment, i want to give users a choice of options using a spinner. To me it seems most logical to have this within my fragment1 class. However it doesn't seem to work. Furthermore at the moment my code works by calling the fragment 1 straight away, like my main activity.xml isn't shown (i'm not sure if this is correct or not, i'm a newb when it comes to android app development).

I'm getting the error on the ArrayAdapter call, marking 'this' as the culprate.

Fragment

public class Page1Fragment extends Fragment {

        @Override

        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle

                savedInstanceState) {



            View view = inflater.inflate(R.layout.page1_fragment, container, false);





            Spinner spinner = (Spinner) view.findViewById(R.id.spinner);

    // Create an ArrayAdapter using the string array and a default spinner layout

            ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, //this is where the error is called

                    R.array.planets_array, android.R.layout.simple_spinner_item);

    // Specify the layout to use when the list of choices appears

            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    // Apply the adapter to the spinner

            spinner.setAdapter(adapter);



            return view;



        }







    }

Error

Wrong 1st argument type. Found: 'provider.ac.tir.ac.uk.finallab.Page1Fragment', required: 'android.content.Context

ArrayAdapter.createFromResource expects a Context, and Fragment is not a Context, so try with its Activity. Simply change:

ArrayAdapter.createFromResource(this, R.array.planets_array, android.R.layout.simple_spinner_item);`

To:

ArrayAdapter.createFromResource(getActivity(), R.array.planets_array, android.R.layout.simple_spinner_item);`
