android - NotificationCompat 和 setFullScreenIntent()

Question

我想知道是否有人对这种类型的通知有一些经验。

在我的用例中，我想从我的服务触发一个通知，而不是它应该打开一个全屏视频。 setFullScreenIntent 方法看起来恰好解决了这个问题，因为它在文档中写道:

An intent to launch instead of posting the notification to the status bar. Only for use with extremely high-priority notifications demanding the user's immediate attention, such as an incoming phone call or alarm clock that the user has explicitly set to a particular time.

所以它说它像来电一样工作。这意味着即使我的手机处于 sleep 状态，我也应该可以全屏查看通知。

但在我的例子中，我只是收到提醒通知，如果我点击它，它会打开 Activity 。甚至认为在文档中他们提到了一些关于这种行为的事情......

On some platforms, the system UI may choose to display a heads-up notification, instead of launching this intent, while the user is using the device.

... 我想知道如何在触发通知时自动打开 Activity 。就像来电屏幕一样。

这是我的服务代码:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {


    Intent notificationIntent = new Intent("android.intent.category.LAUNCHER");
    intent.setClassName("com.example.test",
            "com.example.test.VideoActivity");
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

    PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);

    NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentIntent(contentIntent)
                .setContentTitle("Video")
                .setContentText("Play video")
                .setFullScreenIntent(contentIntent, true);

    NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);



    mNotificationManager.notify(0, mBuilder.build());

    return Service.START_STICKY;
}

尝试在onCreate时用setFullScreenIntent通知notification

@Override
public int onCreate() {
    Intent notificationIntent = new Intent("android.intent.category.LAUNCHER");
    intent.setClassName("com.example.test",
        "com.example.test.VideoActivity");
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

    PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentIntent(contentIntent)
            .setContentTitle("Video")
            .setContentText("Play video")
            .setFullScreenIntent(contentIntent, true);

    NotificationManager mNotificationManager = (NotificationManager) 
   this.getSystemService(Context.NOTIFICATION_SERVICE);

    mNotificationManager.notify(0, mBuilder.build());
}
