I'm new to android. I have created a a navigation drawer and made menus in it, dinamic by adding fragments. Now for each menu I want to create a custom list view with arrayadapter class. I implemented it, but the problem is that the title and address are the same in every item of the list. The list displays only the last item. Can anyone help me please!! I can't figure out the solution. Here is some code and a photo:
import static com.example.user.appsightseeing.R.layout;
public class ParksFragment extends Fragment {
private ArrayList<Park> parks = new ArrayList<>();
public ParksFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(layout.fragment_parks, container, false);
parks.add(new Park("Artificial Lake of Tirana", "The Grand Park of Tirana, also known as the Tirana Park on the Artificial Lake or even the Park of Saint Procopius, is a 230 hectare public park situated on the southern part of Tirana.",
"At the end of Rruga Sami Frasheri.", R.drawable.artificiallake));

"Near Rruga Liqeni i Thate", R.drawable.zoopark));
parks.add(new Park("Memorial park of the Cemetery of the Nation's Martyrs", "The National Martyrs Cemetery of Albania is the largest cemetery in Albania, located on a hill overlooking Tirana. The \"Mother Albania\" statue is located at the Cemetery.",

parks.add(new Park("Vaqarr park", "The second park in Vaqarr, is a recreational area of 97 ha, that is more than useful to inhabitants in Tirana.",
"Vaqarr", R.drawable.vaqarripark));
parks.add(new Park("Farka Lake park", "To the East of the East of Tirana’s city center, Lake Farka is a local favorite for waterborne fun in Summer. Picnicking, jet and water skiing, swimming, boating, all the usual wet sports suspects.",

"Near Zoo park", R.drawable.botanicpark));
parks.add(new Park("Rinia park", "The park, 500 metres (1,600 ft) from the central square, was built in 1950[5] as part of a major urban development program which developed after World War II. It was initially a pleasant family park where inhabitants of Tirana could take their children.",
"Near Bulevardi Deshmoret e Kombit and near Rruga Myslym Shyri", R.drawable.riniapark));
ArrayAdapter<Park> adapter = new parkArrayAdapter(getActivity(), 0, parks);
ListView listView = (ListView) rootView.findViewById(R.id.customListView);
listView.setAdapter(adapter);
return rootView;
//add event listener so we can handle clicks
}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}
The arrayadapter class:
import java.util.List;
public class parkArrayAdapter extends ArrayAdapter<Park> {
private Context context;
private List<Park> parks;
private AnimatedStateListDrawable inflater;
//constructor, call on creation
public parkArrayAdapter(Context context, int resource, ArrayList<Park> objects) {
super(context, resource, objects);
this.context = context;
this.parks = objects;
}
//called when rendering the list
@NonNull
public View getView(int position, View convertView, ViewGroup parent) {
//get the park we are displaying
Park par = parks.get(position);
//get the inflater and inflate the XML layout for each item
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.park_layout, null);
TextView title = (TextView) view.findViewById(R.id.p_title);
TextView description = (TextView) view.findViewById(R.id.p_description);
TextView streetname = (TextView) view.findViewById(R.id.address);
ImageView image = (ImageView) view.findViewById(R.id.image);
//set title and description
String titleT = par.getPark_title();
title.setText(titleT);
//display trimmed excerpt for description
int descriptionLength = par.getPark_description().length();
if(descriptionLength >= 100){
String descriptionTrim = par.getPark_description().substring(0, 100) + "...";
description.setText(descriptionTrim);
}else{
description.setText(par.getPark_description());
}
streetname.setText(par.getPark_streetname());
//get the image associated with this park
int imageID = context.getResources().getIdentifier(String.valueOf(par.getPark_image()), "drawable", context.getPackageName());
image.setImageResource(imageID);
return view;
}
}
The park class:
public class Park {
private static String title;
private String description;
private static String streetname;
private int image;
public Park(String title, String description, String streetname, int image){
this.title = title;
this.description = description;
this.streetname = streetname;
this.image = image;
}
public static String getPark_title() { return title; }
public String getPark_description() {
return description;
}
public static String getPark_streetname() {
return streetname;
}
public int getPark_image() {
return image;
}
}
The park layout for a row:
<?xml version="1.0" encoding="utf-8"?>
