        android:layout_height="wrap_content"
        android:id="@+id/station_name"

</LinearLayout>

fragment.java

public class Fragmentone  extends Fragment{

    ArrayList<String> name;
    boolean isPressed=false;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_one, container, false);
        name=new ArrayList<String>();
        name.add("First Station");
        name.add("Second Station");


        ListView listView = (ListView) view.findViewById(R.id.list_view);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                String item = (String) parent.getItemAtPosition(position);
                Toast.makeText(getActivity(), "Item : " + item, Toast.LENGTH_SHORT).show();
            }
        });

        ArrayAdapter arrayAdapter =new ArrayAdapter(getActivity(),R.layout.row_layout,R.id.station_name,name);
        listView.setAdapter(arrayAdapter);



        return view;
    }


}

Answer 1

your ImageButton has id

"@+id/favorite"

use it to initiate the button in your fragment when onCreateView is called

Imagebutton ib = (Imagebutton)findViewbyId(R.id. favorite);

next add an onclick listener to your button so you know when it's clicked and take appropriate action

ib.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // here you change the image
            }
        });

Answer 2

In the case of fragment you have to pass the view.

Example:

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_one, container, false);

    ImageButton imgBtn = (ImageButton)view.findViewbyId(R.id.favorite);

    imgBtn.setOnClickListener(new View.OnClickListener() {
                @Override 
                public void onClick(View v) {
                    // Do your stuff 
                } 
            }); 

          return view;
    }
