当我在 Android 中显示通知时，通知会放置在 Android 的通知区域中。当我下拉时我可以看到它，但它不会像我看到的许多应用程序那样自动下拉。如何强制通知下拉？我的应用程序打开时这可能吗？它是否仅在我的应用程序关闭或未全屏时才会下拉？
我正在使用 Xamarin，这是我的代码(基本上是从 Google 自己的示例中复制的):
更新 代码 fragment 现在可以工作并显示“提醒”通知。
string title = activity.Resources.GetString(Resource.String.Label_VideoSaved);
string text = string.Format(activity.Resources.GetString(Resource.String.Text_FileLocation), OutputFile);
Notification.Builder b = new Notification.Builder(activity);
b.SetSmallIcon(Resource.Drawable.Icon);
b.SetContentTitle(title);
b.SetContentText(text);
b.Extras.PutString("video", OutputFile);
// create a "heads up" notification with the following 2 lines:
b.SetPriority((int)Android.App.NotificationPriority.High);
b.SetVibrate(new long[0]);
Intent resultIntent = new Intent(activity, typeof(ViewVideoActivity));
TaskStackBuilder stackBuilder = TaskStackBuilder.Create(activity);
stackBuilder.AddParentStack(Java.Lang.Class.FromType(typeof(ViewVideoActivity)));
stackBuilder.AddNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.GetPendingIntent(0, PendingIntentFlags.UpdateCurrent);
b.SetContentIntent(resultPendingIntent);
NotificationManager notificationManager = (NotificationManager)activity.GetSystemService(Context.NotificationService);
notificationManager.Notify(0, b.Build());
最佳答案
我想你想要的是一个“提醒”通知: http://developer.android.com/guide/topics/ui/notifiers/notifications.html#Heads-up
Examples of conditions that may trigger heads-up notifications include:
The user's activity is in fullscreen mode (the app uses fullScreenIntent),
The notification has high priority and uses ringtones or vibrations
