我的代码似乎有问题.我创建了一个测试活动,只是为了看错了,但我还是不能.

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

    String extra = "test";

    NotificationManager myNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    Intent intent = new Intent(this, test.class);

    Notification notification = new Notification(R.drawable.icon, 
            extra, 
            System.currentTimeMillis());
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 
            0,
            intent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    notification.setLatestEventInfo(getApplicationContext(), "title", "text", pendingIntent);
    notification.flags |= Notification.DEFAULT_SOUND;
    notification.flags |= Notification.DEFAULT_LIGHTS;
    notification.flags |= Notification.DEFAULT_VIBRATE;
    notification.flags |= Notification.FLAG_INSISTENT;
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    myNotificationManager.notify(33, notification);

}
}

当通知弹出时,我没有声音和/或振动.

我查看了手机的设置,它们没问题,没有静音,默认声音启用.
