Answer 1

you should create a class as below to pars this JSON

public class Response{


    @SerializedName("next")
    String next;
    @SerializedName("previous")
    String previous;
    @SerializedName("count")
    int count;
    @SerializedName("count")
    int count;

    @SerializedName("results")
    ArrayList<City> results;
}

Answer 2

Error occurs because you map json to java class incorrectly. Use this ones:

import java.util.List;
import com.google.gson.annotations.SerializedName;

public class CityListItemResponse {

    @SerializedName("count")
    public Integer count;
    @SerializedName("next")
    public String next;
    @SerializedName("previous")
    public Object previous;
    @SerializedName("results")
    public List<City> results = null;
}


import com.google.gson.annotations.SerializedName;

public class City {

    @SerializedName("id")
    public Integer id;
    @SerializedName("title")
    public String title;
}

For creating data classes correctly I advise U to use this instrument link
