Android 如何在锁屏上显示安卓推送通知？

我面临在锁屏上显示推送通知的问题。我能够接收通知，但无法在锁屏上显示它们

Notification notification;
notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
            .setAutoCancel(true)
            .setContentTitle(title)
            .setContentIntent(resultPendingIntent)
            .setSound(alarmSound)
            //.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
            .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
            .setWhen(getTimeMilliSec(timeStamp))
            .setSmallIcon(R.drawable.loader)
            .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
            .setContentText(message)
            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC) //to show content on lock screen
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .build();

NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(count, notification);

我也尝试过使用PowerManager，但它只在锁定屏幕上唤醒，而没有在屏幕上显示通知

PowerManager powerManager = (PowerManager) mContext.getSystemService(POWER_SERVICE);

if (!powerManager.isInteractive()){ // if screen is not already on, turn it on (get wake_lock for 10 seconds)
    PowerManager.WakeLock wl = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK |PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.ON_AFTER_RELEASE,"MH24_SCREENLOCK");
    wl.acquire(10000);
    PowerManager.WakeLock wl_cpu = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"MH24_SCREENLOCK");
    wl_cpu.acquire(10000);
}

由于我是android新手，我无法解决这个问题。请帮助我。

手机解锁后，您的通知是否会显示在状态栏中？@Christopher感谢您的快速重播，通知会正确显示在状态栏上，但手机本身已配置为在锁定屏幕上显示通知？作为用户，您可以控制是否希望在锁屏上看到通知。@Christopher非常感谢。我尝试了您建议的方法，效果很好。但他们是否可以通过编程自动选择“在锁屏上显示通知”选项卡？当然，您不能自动操作此设置，但您可以尝试引导用户进入设置->
