Question

我已经查看了logCat上的输出，但我无法在模拟器中看到我的联系人列表

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.

提前致谢。
