I am trying to get database from SQLite database and trying to populate the ListView and also adding data in ArrayList . The ListView is populated nicely but problem is ArrayList is not populated nicely.

Suppose I have data in database like: A B C D E F G H I J K L M N ........ My ListView Showing data in this way. But ArrayList add the data this way: A B C D E F A B C D E F G H ......

That means my ArrayList takes first 6 value then repeat it and then it takes next 6 value then again repeat it ..... . That means When I click item "H" from list view the ArrayList shows me "B". I don't know why it is happening?

My Code, CustomList which extends CursorAdapter

import java.util.ArrayList;

import android.content.Context;
import android.database.Cursor;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import android.widget.CursorAdapter;
import android.widget.TextView;

public class CustomList extends CursorAdapter {

    CheckBox favoriteBox;
    TextView cityName, countryName;
    ArrayList<String> city_name;
    ArrayList<String> country_name;
    ArrayList<String> country_short;
    ArrayList<CheckBox> check_box;

    public CustomList(Context context, Cursor c, ArrayList<String> city_name,
            ArrayList<String> country_name, ArrayList<String> country_short,
            ArrayList<CheckBox> check_box) {
        super(context, c, 0);
        this.city_name = city_name;
        this.country_name = country_name;
        this.country_short = country_short;
        this.check_box = check_box;
    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View retView = inflater.inflate(R.layout.all_city_list, parent, false);

        return retView;
    }

    @Override
    public void bindView(final View view, Context context, Cursor cursor) {
        cityName = (TextView) view.findViewById(R.id.cityName);
        String cityS = cursor.getString(cursor.getColumnIndex("city_name"));
        cityName.setText(cityS);
        city_name.add(cityS);//adding value to ArrayList<String>

        countryName = (TextView) view.findViewById(R.id.countryName);
        String conS = cursor.getString(cursor.getColumnIndex("country_name"));
        countryName.setText(conS);
        country_name.add(conS);//adding value to ArrayList<String>
        country_short.add(""
                + cursor.getString(cursor.getColumnIndex("country_short")));//adding value to ArrayList<String>

        favoriteBox = (CheckBox) view.findViewById(R.id.favoriteCheckBox);
        check_box.add(favoriteBox);
        if (cursor.getInt(cursor.getColumnIndex("favorite")) == 0) {
            favoriteBox.setChecked(false);
        } else {
            favoriteBox.setChecked(true);
        }
    }
}

Class AllCityListFragment which extends Fragment

import java.io.IOException;
import java.util.ArrayList;

import android.os.Bundle;
import android.os.Handler;

import android.widget.Toast;

public class AllCityListFragment extends Fragment {
    private CustomList customAdapter;
    private DatabaseHelper databaseHelper;
    ArrayList<String> city_name = new ArrayList<String>();
    ArrayList<String> country_name = new ArrayList<String>();
    ArrayList<String> country_short = new ArrayList<String>();
    ArrayList<CheckBox> check_box = new ArrayList<CheckBox>();

    public static final String ARG_OS = "OS";
    int pos;
    String sql = "";

    ListView list;
    View view;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.all_city_layout, null);

        databaseHelper = new DatabaseHelper(view.getContext());

        try {
            databaseHelper.createDataBase();
            databaseHelper.openDataBase();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            Toast.makeText(view.getContext(), "Error: " + e.getMessage(),
                    Toast.LENGTH_LONG).show();
            e.printStackTrace();
        }

        list = (ListView) view.findViewById(R.id.citylist);
        list.setFocusable(false);

        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View myview,
                    int position, long id) {
                Toast.makeText(getActivity(),
                        position + " " + city_name.get(position),
                        Toast.LENGTH_LONG).show();
            }
        });

            sql = "SELECT _id, city_name, country_name, country_short, favorite FROM city order by country_name asc;";


        new Handler().post(new Runnable() {
            @Override
            public void run() {
                customAdapter = new CustomList(getActivity(), databaseHelper
                        .getResult(sql), city_name, country_name,
                        country_short, check_box);

                list.setAdapter(customAdapter);
            }
        });

        return view;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }


}

In this picture I clicked "Shirajganj" but the Toast shows me "230 Thakurgaon" position =230 is correct but city_name.get(230) should be "Shirajganj" . I think it is doing wrong when I am trying to add value to ArrayList in binView in CustomList. How can I solve this problem?
