The question is really broad. You should address one issue at a time. Are you facing issues in Fetching the JSON, parsing the JSON or populating the ListView? Start with one, learn how to do it, and if you face issues, post your question here, with the code that doesn't work at your end. — Shamas S

As mentioned the question is too broad, just to give the approach I would take.

Build the model class in this case: City
I would advise using retrofit(http://square.github.io/retrofit/) for the network call, so build the interface
Make the network call
Add the retrieved results in a recyclerview adapter

Using Gson can do the json parsing job for you. Its easy to integrate and handy to parse json data. You simply need to create a class containing city_id and city_name.

City.java

public class City {

    private String city_id;
    private String city_name;

    public City() {

    }

    public String getCityId() {
        return city_id;
    }

    public String getCityName() {
        return city_name;
    }
}

Now add another class. E.g. CityList.java

import java.util.List;

public class CityList {

    private List<City> cityList;

    public CityList() {
    }

    public List<City> getCityList() {
        return cityList;
    }

}

Now from json string, parse the data into the CityList class.

Gson gson = new Gson();
CityList myCityList = gson.fromJson(jsonString, CityList.class);

Add the gradle dependency for Gson in build.gradle

compile 'com.google.code.gson:gson:2.3'
