How to add coordinates in a TextView for each list item of the ListView

Question

I'm developing my first App ever, but I'm facing a problem that I cannot overcome. I'm creating a ListView for restaurants in which (Name, Phone, Logo, and Location) for each one will be shown in its List Item.

Everything is going well except for the coordination. I was able only to hardcode the coordinates in getview method, but I don't know how to change it along with the arraylist.

Is there a way to add it to the arraylist as another Arguement?

Any help will be much appreciated :)

These are my codes in which I just added a string for the location and Intent to open the fixed coordinates.

for the new object class:

public class Cell {
private String mName;
private String mPhone;
private int mLogo;
private String mLocation;


public Cell (String name, String phone, int logo, String location){
    mName = name;
    mPhone = phone;
    mLogo = logo;
    mLocation = location;}

public String getmName() {return mName;}

public String getmPhone(){return mPhone;}

public int getmLogo(){return mLogo;}

public String getmLocation() {return mLocation;}

this for the customAdapter:

public class CellAdapter extends ArrayAdapter<Cell> {

private static final String LOG_TAG = CellAdapter.class.getSimpleName();

public CellAdapter(Activity context, ArrayList<Cell> restaurant) {
    super(context, 0, restaurant);
}

@NonNull
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View listItemView = convertView;
    if (listItemView == null) {
        listItemView = LayoutInflater.from(getContext()).inflate(
                R.layout.list_item, parent, false);

    }

    final Cell currentNumber = getItem(position);

    TextView mapView = (TextView) listItemView.findViewById(R.id.map_view);
    mapView.setText(currentNumber.getmLocation());
    mapView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent mapIntent = new Intent(Intent.ACTION_VIEW);
                mapIntent.setData(Uri.parse("geo:47.6, -122.3"));
                getContext().startActivity(mapIntent);
        }
    });

    TextView nameView = (TextView) listItemView.findViewById(R.id.name_view);
    nameView.setText(currentNumber.getmName());

    TextView phoneView = (TextView) listItemView.findViewById(R.id.phone_view);
    phoneView.setText(currentNumber.getmPhone());
    phoneView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent call = new Intent(Intent.ACTION_DIAL);
            call.setData(Uri.parse("tel: " + currentNumber.getmPhone()));
            getContext().startActivity(call);
        }
    });

    ImageView logoView = (ImageView) listItemView.findViewById(R.id.logo_view);
    logoView.setImageResource(currentNumber.getmLogo());


    return listItemView;

}

and this is the activity code:

public class RestaurantsActivity extends AppCompatActivity {Intent mapIntent;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_restaurants);

    final ArrayList<Cell> restaurant = new ArrayList<>();{
        restaurant.add(new Cell("Restaurant 1", "12345", R.drawable.logo_1, "MAP"));
        restaurant.add(new Cell("Restaurant 2", "67890", R.drawable.logo_2, "MAP"));

        CellAdapter restaurantAdapter = new CellAdapter(this, restaurant);



        ListView restaurantView = (ListView) findViewById(R.id.restaurant_view);
        restaurantView.setAdapter(restaurantAdapter);

            }
        }

    }

The final result I need is to update the data in mapIntent with different restaurants when the user click (MAP):

Can you share an image for the layout you need and another one that appeared to you — Al-Mustafa Azhari, Mar 18 '18 at 09:25

The following steps should help you solve this if I got your question correctly:

Add another field to Cell to represent the location URI.
Get this new field and use it to set the currently hardcoded value. e.g mapIntent.setData(currentNumber.getLocationURI());
Then, when creating the Cell objects, you need to pass in the location URI like you did for its other fields in the Cell constructor.

Thanks azeez for the reply. In this method I'd be using the location link from google maps for instance, right ? I'm trying it and it looks promising. but is there an easy way to use lat&long. ? – Ahmed Mar 19 '18 at 05:03
I'm not sure I understand what you mean by an easier way. But: - What do the location links from google maps look like? can you share an example. Maybe you could just parse the Lat and Long from the String? - If you have access to the Location object, then the Longitude and Latitude will be as easy as in this question https://stackoverflow.com/questions/2227292/how-to-get-latitude-and-longitude-of-the-mobile-device-in-android – Azeez Olaniran Mar 19 '18 at 10:14
what I did is adding a String field in my Cell class and put the google map link as an argument (example:www.google.com/maps/place/...) So when the view is clicked, mapIntent open this link. I'm wondering if there is a way for a beginner if I need to use lang and lat data :) ? – Ahmed Mar 19 '18 at 12:56
