I implemented a listview in one of the fragments. How do I make another activity appear when I click?(Beginner)

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int pos, long l) {
    adapterView.getItemAtPosition(pos); 
    // You can import items that you clicked on in this way.  I don't know what kind of data structure the item was made in the list view, but you can bring the item, check it, and make a branch with an if statement or case clause to call the activity. 
            }

Intentint=newIntent(getActivity(), the activity you want to invoke.class);
startActivity(intent);

public class SocialFragment extends Fragment {
    Static final String[] LIST_MENU = {"★"Club List2", "Club List3", "Club List4", "Club List5", ★ Literature-related Division", "Club List8", "Club List9", "Club List10", "★", "Club List13", "Club List12"

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.social_layout, null);
        ArrayAdapter Adapter = new ArrayAdapter(getActivity(), android.R.layout.simple_list_item_1, LIST_MENU);

        ListView listview = (ListView) view.findViewById(R.id.listView);
        listview.setAdapter(Adapter);
        return view;

listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    public void onItemClick(AdapterView<?> adapterView, View view, int pos, long l) {
        adapterView.getItemAtPosition(pos);
        if (LIST_MENU == null) {
            Intent intent = new Intent(getActivity(), List1.class);
            startActivity(intent);
        }
    }
If you write }; //this part), an error appears under the red underline. Please solve this, too.
    }

}
