在状态栏中显示通知文本

在我的应用程序中，我需要向用户显示通知。通过在Android设备标题栏中显示图标和内容标题，下面的代码片段效果很好。

$ p $ var notificationManager = GetSystemService（Context .NotificationService）作为NotificationManager; var uiIntent = new Intent（this，typeof（MainActivity））; var notification = new Notification（Resource.Drawable.AppIcon，title）; notification.Flags = NotificationFlags.AutoCancel; notification.SetLatestEventInfo（this，title，desc，PendingIntent.GetActivity（this，0，uiIntent，0））; notificationManager.Notify（1，通知）;

当我尝试构建用于部署应用程序的包时，出现以下错误：

Android.App.Notification.SetLatestEventInfo（Android.Content.Context， string，string，Android.App.PendingIntent）'已过时：'deprecated'

所以我发现了这个代码片段，我应该使用它，它显示状态栏中的图标不是内容title

意图resultIntent = new Intent（this，typeof（MainActivity））; PendingIntent pi = PendingIntent.GetActivity（this，0，resultIntent，0）; NotificationCompat.Builder builder = new NotificationCompat.Builder（Forms.Context） .SetContentIntent（pi） .SetAutoCancel（true） .SetContentTitle（title） .SetSmallIcon（Resource.Drawable.AppIcon） .SetContentText（desc）; //这是显示 的图标NotificationManager nm = GetSystemService（Context.NotificationService）作为NotificationManager; nm.Notify（_TipOfTheDayNotificationId，builder.Build（））;

我需要在新的代码片段中设置什么来显示Android设备状态中的内容标题bar？

解决方案

我需要将 .setTicker（）添加到第二个代码片段在Android设备状态栏中显示文本

In my application I need to display notification to the user. The following code snippet worked great by display the icon and content title in the Android device title bar.

var notificationManager = GetSystemService(Context.NotificationService) as NotificationManager; var uiIntent = new Intent(this, typeof(MainActivity)); var notification = new Notification(Resource.Drawable.AppIcon, title); notification.Flags = NotificationFlags.AutoCancel; notification.SetLatestEventInfo(this, title, desc, PendingIntent.GetActivity(this, 0, uiIntent, 0)); notificationManager.Notify(1, notification);

When I tried to build the package for deploying the application, I get the following error:

Android.App.Notification.SetLatestEventInfo(Android.Content.Context, string, string, Android.App.PendingIntent)' is obsolete: 'deprecated'

So I found this code snippet I should be using and it shows the icon in the status bar by not the content title

Intent resultIntent = new Intent(this, typeof(MainActivity)); PendingIntent pi = PendingIntent.GetActivity(this, 0, resultIntent, 0); NotificationCompat.Builder builder = new NotificationCompat.Builder(Forms.Context) .SetContentIntent(pi) .SetAutoCancel(true) .SetContentTitle(title) .SetSmallIcon(Resource.Drawable.AppIcon) .SetContentText(desc); //This is the icon to display NotificationManager nm = GetSystemService(Context.NotificationService) as NotificationManager; nm.Notify(_TipOfTheDayNotificationId, builder.Build());

What do I need to set in the new code snippet to display the content title in the android device status bar?

解决方案

I need to add .setTicker() to the second code snippet to have text display in the Android device status bar
