I have an app and inside it only one activity (main activity) and layout XML of main activity have only 
list view . This app will get restaurants near from my location and display it in list view.
What I need to do is add button to the main activity layout, when I press on button get to me list of restaurant item by item
from json file and display it in list view but not display all restaurants in one click but show item by item
every click get restaurant.

suppose I have 3 restaurant in json file
when I click on button for first click get me first restaurant
when I click on button for second click get me second restaurant
when I click on button for third click get me third restaurant 
How to customize this code to accept get item by item restaurant from json file
My code includes class and activity and code is working success  
my class is FoursquareVenue

public class FoursquareVenue
{

    private String category;

    public FoursquareVenue() {
        this.name = "";
        this.city = "";
        this.setCategory("");
    }

    public String getCity() {
        if (city.length() > 0) {
            return city;
        }
        return city;
    }

    public void setCity(String city) {
        if (city != null) {
            this.city = city.replaceAll("\\(", "").replaceAll("\\)", "");
            ;
        }
