![]() ![]() I don't think this is a good approach as it has its own NavigationPage so that it should utilize its own navigation instead of the parent's. Moreover, I noticed that your MessagePageViewModel used the parent tabbed view model's navigation. Public MessagePageViewModel(INavigation navigation, Master_PageViewModel viewModel)Īt last, trigger the method in your refresh command: public ICommand RefreshCommand Messages = new MessagePageViewModel(Navigation, this) Īnd change your message page view model's constructor: Master_PageViewModel parentViewModel You have to pass the parent tabbed view model to your MessagePageViewModel like: public Master_PageViewModel(INavigation navigation) It is not the parent tabbed page's binding context so the tab's badge won't be updated even though the GetCounter has been triggered. This is because you created a new instance of Master_PageViewModel in your RefreshCommand. Private async Task MessageDetails(object obj)Īwait Navigation.PushAsync(new MessageDetailsPage(.)) MessagesList = new ObservableCollection(msg) MessageDetailsCommand = new Command(async (object obj) => await MessageDetails(obj)) ReloadCommand = new Command(async () => await ReloadPage()) ![]() Public MessagePageViewModel(INavigation navigation) Master_PageViewModel vm = new Master_PageViewModel(Navigation,multiMediaPickerService) Master Tab Page ViewModel: public class Master_PageViewModel : INotifyPropert圜hanged This.BindingContext = vm = new Master_PageViewModel(Navigation) Public partial class MasterTabPage : TabbedPage If anyone can help i will be very grateful. When i Navigate to view the message it updates the database of that the message has been read, I then navigate back to the tabbed page with a popasync, I then pull to refresh which executes the call to get amount of messages read but it not updating the the counter, if i put a break point on the GetCounter method i see it is updating the counter with the right amount but not changing in on the badge. ![]() So I have a call to retrieve the amount of unread messages from the database which is populating into the counter on app load. I am having trouble updating the counter. I have a badge on one of the tabs that has a counter which shows how many messages there are. I populate all my other tab pages, I have a viewmodel that binds to the Parent tab page and viewmodels for each of the other Tab pages. intent.I have a App that uses tabbed pages, In the xaml of the Parent tab page clear notification badge from Samsung : set count zero.Intent.putExtra("badge_count_class_name", launcherClassName) Intent.putExtra("badge_count_package_name", context.getPackageName()) at 16:25 So how many apps have this notification on Android, for example, the Facebook app and Whatsapp Pedro Paulo at 16:50 They only offer those badges on devices with a launcher that supports it, and they have code that supports the different APIs for those launchers. Samsung content provider opposite to Sony, Broadcast an intent for Samsung Intent intent = new Intent("_COUNT_UPDATE").Intent.putExtra("._NAME", context.getPackageName()) Ĭom.badge.ACTIVITY_NAME : name of your app mainActivity use to know which icon to show the badge.Ĭom.badge.SHOW_MESSAGE: true/false indicate you want to show badge or not.Ĭom.badge.MESSAGE: display the number of badge.Ĭom.badge.PACKAGE_NAME: your application Package name. Intent.putExtra("._NAME", launcherClassName) Once you see, clear notification badge from preference and also with badge count simply send a new broadcast, this time with SHOW_MESSAGE set to false: Intent intent = new Intent().Broadcast an Intent to the BadgeReceiver to show the badge on app.ShortcutBadger.appl圜ount(context, badgeCount) Updating the badge count in the application icon.Declare the permission in your manifest file.Badges count function works really well with LG, Sony, Samsung, HTC.įor better understanding, let’s see an example, how badges are shown in Sony Ericsson and Samsung handsets: All the handset doesn't provide badge count, it fully depends on the manufacturer. It is handled by using a broadcast receiver. However, one of the ways to do it in a simple way is by adding badge num on your application icon in launcher. As a badge count there is no standard way of doing this. ![]()
