How to get data from database instead of resource in android

I am trying to get data from database instead of string resource.

Here is my code. where I want to show the data as a ListView. My ListView is now currently working with a custom list adapter.

import android.app.Fragment;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ListView;
import com.rupomkhondaker.sonalibank.adapter.PhoneListAdapter;
import com.rupomkhondaker.sonalibank.model.ContactItem;
import java.util.ArrayList;


public class GMOFragment extends Fragment {
    public GMOFragment(){}

    private ArrayList<ContactItem> phoneItems;
    private PhoneListAdapter adapters;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_gmo, container, false);

        final ArrayList<ContactItem> listData = getListData();

        final ListView listView = (ListView) rootView.findViewById(R.id.gmolistView);
        listView.setAdapter(new PhoneListAdapter(getActivity(), listData));


        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) {
                ContactItem newsData = (ContactItem) listView.getItemAtPosition(position);

                Intent intent = new Intent(getActivity(), ContactDetail.class);
                intent.putExtra("DATA_KEY", newsData);
                startActivity(intent);
            }

        });

        return rootView;
    }

    private ArrayList<ContactItem> getListData() {
        ArrayList<ContactItem> listMockData = new ArrayList<ContactItem>();

        String[] names = getResources().getStringArray(R.array.gmo_name_list);
        String[] phones = getResources().getStringArray(R.array.gmo_ph_list);
        String[] mobiles = getResources().getStringArray(R.array.gmo_mob_list);
        String[] emails = getResources().getStringArray(R.array.gmo_email_list);

        for (int i = 0; i < names.length; i++) {
            ContactItem newsData = new ContactItem();
            newsData.setName(names[i]);
            newsData.setPhone(phones[i]);
            newsData.setMobile(mobiles[i]);
            newsData.setEmail(emails[i]);
            listMockData.add(newsData);
        }
        return listMockData;
    }
} 

Here is My DataBaseHepler.java this create the database successfully !

        }

        localDbStream.close();
        externalDbStream.close();

    }

    public SQLiteDatabase openDataBase() throws SQLException {
        String path = DB_PATH + DB_NAME;
        if (database == null) {
            createDataBase();
            database = SQLiteDatabase.openDatabase(path, null,
                    SQLiteDatabase.OPEN_READWRITE);
        }
        return database;
    }
    @Override
    public synchronized void close() {
        if (database != null) {
            database.close();
        }

    }

    @Override

Please help me to set data into getListData() from my database instead of resource.

Note: My database has same columns like listarray with same data.
