在我的应用程序中,我需要向用户显示通知。以下代码片段非常有效,可以在 Android 设备标题栏中显示图标和内容标题。
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);
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:'已弃用'
所以我发现我应该使用这个代码片段,它在状态栏中显示图标而不是内容标题
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());
我需要在新代码片段中设置什么才能在 Android 设备状态栏中显示内容标题?
