Cannot resolve constructor ArrayAdapter (Listview , fragment )

Question

I want to load a listview in my fragment and the problem with the adapter is the error - Cannot resolve constructor ArrayAdapter.

This is the onCreateView method in my class :

 public class AndroidGUIModifier implements IMyComponentGUIModifier, IFragmentEvents {

    @Override
    public void onCreateView() {
        tv1 = (TextView) fragment.findViewById("xtv1");
        tv2 = (TextView) fragment.findViewById("xtv2");
        lv=(ListView) fragment.findViewById("xdevices") ;

        mydevices = new ArrayList<String>();

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(AndroidGUIModifier.this,android.R.layout.simple_list_item_1,mydevices);// the problem here : Cannot resolve constructor ArrayAdapter

        lv.setAdapter(adapter);
    }

}

Obtain the Context from the fragment and just pass it to the ArrayAdapter :

ArrayAdapter<String> adapter = new ArrayAdapter<String>(fragment.getContext(), android.R.layout.simple_list_item_1, mydevices);

I got this : Cannot resolve constructor 'ArrayAdapter(java.security.AccessControlContext, int, java.util.List<java.lang.String>)

Are you extending Fragment?

public class AndroidGUIModifier implements IMyComponentGUIModifier, IFragmentEvents {

If it is inside a fragment, you need to pass context for the first argument usually like this I think?

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, mydevices);

If you are using AndroidGUIModifier as your fragment, can you try extending the Fragment class?

public class AndroidGUIModifier extends Fragment implements IMyComponentGUIModifier, IFragmentEvents {
