在状态栏中显示通知文本 - Android [英] Display Notification Text in Status Bar - Android

问题描述

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Android.App.Notification.SetLatestEventInfo(Android.Content.Context, string, string, Android.App.PendingIntent)' is obsolete: 'deprecated'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