Rajouter le Listener sur les boutons

Bonjour
Voici comment rajouter le Listener sur les boutons d'Android:

public class NotificationHomeActivity extends Activity {
private Button addNotificationBtn;
private Button deleteNotificationBtn;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

addNotificationBtn = (Button) findViewById(R.id.add_notification);
addNotificationBtn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
Toast.makeText(getBaseContext(), "Ajout d'une notification", Toast.LENGTH_SHORT).show();
}
});

deleteNotificationBtn = (Button) findViewById(R.id.delete_notification);
deleteNotificationBtn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
Toast.makeText(getBaseContext(), "Suppression d'une notification", Toast.LENGTH_SHORT).show();
}
});
}
}
