如何顯示其保存在清單列表<>

Question

我已經看到在logcat的輸出，但我不能看到我的聯繫人列表中的模擬器

import java.util.List; 
import android.app.Activity; 
import android.os.Bundle; 
import android.util.Log; 
import android.widget.ListView; 


public class dbb extends Activity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    DatabaseHandler db = new DatabaseHandler(this); //i have created this class 

    /** 
    * CRUD Operations 
    * */ 
    // Inserting Contacts 
    Log.d("Insert: ", "Inserting .."); 
    db.addContact(new contact("Ravi", "9100000000")); 
    db.addContact(new contact("Srinivas", "9199999999")); 
    db.addContact(new contact("Tommy", "9522222222")); 
    db.addContact(new contact("Karthik", "9533333333")); 

// Reading all contacts 
    Log.d("Reading: ", "Reading all contacts.."); 
    List<contact> contacts = db.getAllContacts(); 
    ListView lv = new ListView(this); 
    lv = (ListView)findViewById(R.id.list1);   

for (contact cn : contacts) { 
     String log = "Id: "+cn.getID()+" ,Name: " + cn.getName() + " ,Phone: " + cn.getPhoneNumber(); 
      // Writing Contacts to log 
    Log.d("Name: ", log); 
    } 

    } 
} 

*//Here what should i do to show List[contact] as my desired output? which is saved in the list array. 

在此先感謝。
