我试图展示通知型的单挑,但我不能.我尝试了什么

final Notification.Builder notif = new Builder(getApplicationContext())
    .setContentTitle(getString(R.string.title))
    .setContentText(getString(R.string.text))
//  .setTicker(getString(R.string.tick)) removed, seems to not show at all
//  .setWhen(System.currentTimeMillis()) removed, match default
//  .setContentIntent(contentIntent) removed, I don't neet it
    .setColor(Color.parseColor(getString(R.color.yellow))) //ok
    .setSmallIcon(R.drawable.ic_small) //ok
    .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher))
//  .setCategory(Notification.CATEGORY_CALL) does not seem to make a difference
    .setPriority(Notification.PRIORITY_MAX); //does not seem to make a difference
//  .setVisibility(Notification.VISIBILITY_PRIVATE); //does not seem to make a difference

mNotificationManager.notify(Constants.NOTIFICATION_ID, notif.build());

通知仅显示为栏中的图标.我使用的是API 21 API 21仿真器(不要使用L预览)我曾尝试:
android:Theme.Holo.NoActionBar,
android:Theme.Holo.NoActionBar.Fullscreen
和NotificationCompat.Builder

SDK示例不可用.有谁知道怎么做？

我通过添加:

.setDefaults(Notification.DEFAULT_VIBRATE)

这是最好的方法吗？
