import android.os.Bundle;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.app.Activity;
import android.app.ListActivity;
import android.database.Cursor;
import android.view.Menu;
import android.widget.ListAdapter;

public class CustomBaseAdapterActivity extends  ListActivity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.list);
		String[] projections = new String[] { Phone._ID,
				Phone.DISPLAY_NAME, Phone.NUMBER, Phone.TYPE };
				Cursor c = getContentResolver().query(Phone.CONTENT_URI,
				projections, null, null, null);
				startManagingCursor(c);
				List<ContactEntry> contacts = new ArrayList<ContactEntry>();
				while (c.moveToNext()) {
				int nameCol = c.getColumnIndex(Phone.DISPLAY_NAME);
				int numCol = c.getColumnIndex(Phone.NUMBER);
				int typeCol = c.getColumnIndex(Phone.TYPE);
				String name = c.getString(nameCol);
				String number = c.getString(numCol);
				int type = c.getInt(typeCol);
				contacts.add(new ContactEntry(name, number, type));
				}
				// CREATE ADAPTER USING LIST OF CONTACT OBJECTS
				ContactBaseAdapter cAdapter = new ContactBaseAdapter(this,
				 
				 this.setAdapter
				}
	

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.custom_base_adapter, menu);
		return true;
	}

}

i use above code to display contact numbers on the screen. how i use Loader class class instead of startManagingCursor(c);
